A Minor Girl's Right of Mi'un

One should not marry a girl who is still a minor.

Although a father has the authority to arrange for his minor daughter, instructed that this should not ordinarily be done. Rather, she should be allowed to mature and express whom she wishes to marry.

If a man marries a minor girl who is an orphan,

established a form of marriage for a minor orphan so that she could have someone to care for and protect her. Since she has no father who can effect -level for her, this marriage has Rabbinic rather than full -level force.

-

and she does not wish to remain with this husband—

she may perform mi'un and leave,

and she does not require a from him;

because the of a minor in this situation are not complete ,

as we have explained.

Mi'un is the minor girl's refusal to continue this Rabbinically established marriage. Because these do not have the full -level force of ordinary , gave her the ability to reject the marriage while she is still entitled to mi'un. She then leaves without requiring a .

Mi'un is therefore not a form of divorce through a . It is the mechanism established through which a minor can reject this particular type of Rabbinic marriage.

This right is temporary. Once she reaches adulthood, mi'un is no longer available. Whether the marriage has also become fully binding under law depends on what occurred after she reached maturity, as explained in 4–6.

Similarly, if a girl's father married her off while she was a minor,

In this case, the original marriage is fundamentally different. arranged by her father while he has authority over her are binding under law and cannot be ended through mi'un.

and she was then widowed or divorced,

-

while she was still a minor—

she is considered like an orphan even though her father is still alive;

Although her father is alive, she is treated like an orphan for this law. Once the marriage arranged by her father has ended, his authority to arrange another -level for her does not return.

and if she marries again while she is still a minor,

she may end that marriage through mi'un.

Her original marriage arranged by her father could not have been ended through mi'un. But once that marriage has ended through widowhood or divorce, a later marriage entered while she remains a minor has the Rabbinic status that can be rejected through mi'un.

Synopsis

A minor orphan may end her Rabbinically established marriage through mi'un without receiving a . The same applies to a minor whose father originally married her off, if that -level marriage first ended through divorce or widowhood and she then entered another marriage while still a minor.

Why a Cannot Use Mi'un

-

With regard to a —

A in this context is a deaf-mute woman with the limited legal capacity associated with that status.

although her marriage is established by Rabbinic law,

-

like the marriage of a minor girl—

At first glance, we might expect her to have the same right of mi'un as the minor discussed in Halachah 1. In both cases, the marriage is a Rabbinic institution rather than an ordinary -level marriage.

the Sages did not establish the right of mi'un for her,

so that men would not refrain from marrying her.

A minor's right to mi'un has a built-in endpoint: when she reaches adulthood, her status changes and the special right ends. A 's status does not automatically change with age in the same way, so such a right would have no comparable built-in endpoint.

If she could end her marriage through mi'un indefinitely, men might be reluctant to marry her in the first place. therefore did not establish mi'un for her, even though her marriage, like the minor's, is Rabbinic.

Synopsis

Although the marriage of a is Rabbinic like the marriage of a minor, did not give her the right of mi'un. A minor's right ends when she matures; for a , such a right would have no comparable built-in endpoint and could discourage men from marrying her.

How Broadly a Minor Can Exercise Mi'un

-

A minor girl may exercise her right of mi'un—

The now defines how broadly this right operates while she remains a minor.

whether she is only in the stage of ,

or she has already entered nisu'in,

Mi'un is not limited to the period before the couple begins married life. As long as she still qualifies for this right, she may exercise it even after nisu'in.

whether in her husband's presence,

or when he is not present.

Her husband's presence or consent is not what gives mi'un its effect.

Just as she may perform mi'un with regard to her husband,

so too she may perform mi'un with regard to a .

If her husband dies childless and she becomes bound to a , mi'un can terminate that bond as well. She does not have to proceed with .

She may perform mi'un with one husband,

then marry another man,

and perform mi'un with the second husband,

-

and likewise with a third—

even any number of times.

There is no rule that exercising mi'un once exhausts the right. As long as she remains a minor and enters marriages to which mi'un applies, she may exercise the right repeatedly.

As long as she remains a minor, she has the right to perform mi'un.

This is the basic time limit on the special right. The following will define more precisely when she is no longer treated as a minor for this purpose.

If a minor girl did not formally perform mi'un,

even though she is married,

and she went and accepted from another man,

-

while she was still a minor—

those very are themselves her mi'un.

Ordinarily, a married woman cannot accept from another man. Here, however, her first marriage is the special Rabbinic marriage of a minor that she still has the power to reject through mi'un.

By knowingly accepting from another man while she still possesses that right, she unmistakably rejects her first marriage. Those new themselves are therefore treated as her act of mi'un: קידושיה הן הן מיאוניה — her are themselves her mi'un.

Synopsis

A minor who has the right of mi'un may exercise it after or nisu'in, in or outside her husband's presence, and even toward a . She may exercise mi'un repeatedly while she remains a minor. If she instead accepts from another man while still entitled to mi'un, those new themselves constitute her rejection of the first Rabbinic marriage.

When the Right of Mi'un Ends

Until when may a girl exercise her right of mi'un?

The previous established that mi'un is available only while she remains a minor. The now defines when that period ends.

As long as she remains a minor,

until she becomes a na'arah,

A na'arah is a girl who has reached the next stage of maturity. Once she reaches that stage, the special right of mi'un ends.

or until it becomes known that she is an .

An is a woman whose development establishes that she does not follow the ordinary pattern of female physical maturity and is regarded as incapable of bearing children. Once she is established as an , she likewise no longer exercises mi'un as a minor.

When does this apply?

The now qualifies the ruling. Once she reaches the age when signs of maturity are expected, whether marital relations took place afterward becomes crucial.

When her husband did not have relations with her

after she became twelve years and one day old.

After she reaches twelve years and one day, we ordinarily presume that she has developed the physical signs of maturity. If she has not had marital relations after reaching that age, however, it can still be relevant to determine through examination whether she actually developed those signs.

But if she reached this age

-

and then had marital relations,

since relations effect under law,

as we have explained,

she can no longer exercise mi'un.

Once she reaches twelve years and one day, we ordinarily presume that she has developed the signs of maturity. If her husband then has marital relations with her, those relations establish the marriage on the level. Mi'un, which applies to the special Rabbinic marriage of a minor, can therefore no longer terminate the relationship.

And she does not require an examination for purposes of mi'un,

because we presume that she has developed the signs of physical maturity.

This — legal presumption is the starting point once she reaches twelve years and one day: unless established otherwise, we assume that she has matured.

If she has not had marital relations after reaching twelve and wants to establish that she still qualifies for mi'un, an examination showing that she has not developed signs of maturity can establish that she remains a minor for this purpose.

The next addresses the more complicated situation in which such an examination finds no signs, but marital relations had already taken place after she reached the age when those signs could have appeared.

Synopsis

A girl may exercise mi'un only while she retains the status of a minor. Once she becomes a na'arah or is established as an , that right ends. After twelve years and one day, she is ordinarily presumed to have developed signs of maturity; if marital relations then take place, those relations establish -level and mi'un can no longer end the marriage.

When Her Physical Maturity Is Uncertain

If she was physically examined

-

and no signs of maturity were found—

At first glance, the examination seems to establish that she is still a minor. But here there is an additional fact: marital relations had already taken place after she reached the age when signs of maturity could have appeared.

since she had marital relations

after reaching the age at which signs of maturity could be expected,

we are concerned

that perhaps she developed the signs and they later fell away,

The examination establishes only that the signs are not present now. It does not prove that they were never present.

Perhaps she had already developed signs of maturity before the marital relations and those signs later disappeared. If so, she was already mature when those relations took place, and the relations established -level .

Therefore, she requires a because of the doubt.

There are two possibilities.

If she never developed signs of maturity, she remained a minor and her marriage retained the Rabbinic status that could be ended through mi'un.

If she had already developed the signs before the marital relations and they subsequently disappeared, those relations established -level , which mi'un cannot terminate.

Because we cannot determine whether she had already matured when those relations occurred, she requires a because of the possibility that -level took effect.

If she performed mi'un after being examined,

-

and then became to another man—

She performed mi'un after an examination showed no present signs of maturity. But the earlier uncertainty remains: perhaps she had previously matured, had relations with her first husband, and only afterward lost those signs.

she requires a from the second man because of the doubt;

Here the two possibilities lead to opposite results.

If she was still a minor, her mi'un ended the first Rabbinic marriage and the second man's took effect.

If she had already matured before the earlier marital relations, those relations established -level with the first husband. Her later mi'un could not end that marriage, and the second man's could not take effect.

We cannot determine which situation actually occurred, so the second relationship must also be treated as doubtful.

-

And if she entered nisu'in with the second man—

she must leave both men,

and a child from either man has the status of a safek — a doubtful .

This consequence concerns children fathered after the second .

If the first marriage became binding under law, a child subsequently fathered by the second man may have been conceived while she was still married to the first.

But if she truly remained a minor, her mi'un was valid and the second man's took effect. A child subsequently fathered by the first man may then have been conceived while she was bound to the second.

Because we cannot determine which marriage was binding, a child subsequently fathered by either man after the second has the status of a safek .

Synopsis

If a girl had marital relations after reaching the age when signs of maturity could appear, a later examination finding no signs does not prove that she was still a minor—the signs may have appeared and then fallen away. She therefore requires a because -level may have taken effect. If she then performs mi'un and becomes to another man, it is uncertain which relationship is binding; if she proceeds to nisu'in, she must leave both men, and a child subsequently fathered by either man has the status of a safek .

When She Grows Up Without Renewed Relations

If a minor girl did not perform mi'un and then reached adulthood,

even though her husband did not have relations with her

-

from the time she became twelve years and one day old—

This case differs from the previous two . Here, no later marital relations occurred that could establish a -level basis for the marriage.

she can no longer exercise mi'un,

because she has reached adulthood.

Mi'un is a special right that exists only while she remains a minor. Once she has grown up, that right ends even though her husband did not have relations with her after she reached the relevant age.

And she requires a by Rabbinic law.

She still requires a , but not because later relations established -level . Her need for a comes from the Rabbinic marriage she entered while she was still a minor.

The now carefully rules out the two ways in which later relations could have given the marriage a stronger status.

For her husband did not have relations with her

after she reached the age of na'arut,

which would have required us to be concerned

that perhaps she had developed signs of maturity

and was therefore doubtfully ,

This rules out the uncertainty discussed in Halachah 5. There were no relations during the period in which we might wonder whether she had already developed the physical signs of maturity and thereby acquired a -level marital status.

nor did he have relations with her after she had definitely reached adulthood

which would have made her a fully married woman,

This also rules out definite -level through later relations.

There were therefore neither relations creating a doubt about nor relations after definite adulthood that would make the marriage fully binding under law.

It follows that she requires a

only because of the marriage she entered while she was a minor,

which is a Rabbinic institution.

Nothing occurred after her childhood marriage to establish -level . Her bond to the first husband therefore remains Rabbinic, and that Rabbinic bond is the sole reason she requires a .

Therefore, if after reaching adulthood she went and became to another man,

the second man's take effect.

Because her bond to the first husband remains only Rabbinic, it does not prevent another man's -level from taking effect after she reaches adulthood.

There are now two different levels of relationship at the same time:

The first husband's bond remains Rabbinic.

The second man's have -level force.

Keeping that distinction in mind explains the rulings that follow.

If the first husband divorces her,

the second man may proceed to nisu'in with her.

The second man's have already taken effect, but she may not proceed to nisu'in with him while the Rabbinic bond to the first husband remains. Once the first husband gives her the required , that remaining bond is removed and the second man may proceed to nisu'in.

But if the second man divorces her,

-

the first husband may not continue his marriage with her—

lest people say,

“He took back his divorcee

after she had become to another man.”

Once the second man's have taken effect and he later divorces her, do not allow her to remain with the first man. Otherwise, it could appear that the first husband took back his divorcee after she had become to someone else.

If the second man had relations with her

-

before the first husband divorced her—

she must leave both men,

because her situation resembles that of a woman

who heard that her husband had died,

married another man,

and afterward her first husband returned.

The resemblance is that she entered into a second marriage before her bond to the first husband had been formally severed. Because of that similarity, require her to leave both men.

A child from the second man, however, is not a .

The resemblance to the earlier case does not extend to the child's status.

The first husband's bond is only Rabbinic, while the second man's have -level force. A child from the second man is therefore not a .

But if the first husband had relations with her

before the second man divorced her,

the child is a .

Here the -level relationship is with the second man. Once his have taken effect, a child subsequently fathered by the first husband while that second marriage remains in force is a .

The difference between the two children therefore follows directly from which relationship has force: the first husband's bond is only Rabbinic; the second man's are binding under law.

Synopsis

If a minor's Rabbinic marriage continues until she reaches adulthood without later relations with her first husband, she loses the right of mi'un but requires a only by Rabbinic law. Because the first bond remains Rabbinic, -level from a second man can take effect. The later rulings—including the different status of children from the two men—follow from the distinction between the first husband's Rabbinic bond and the second man's -level .

Picture the CaseA concrete example

married as a minor and later grew up, but her first husband never had relations with her after she reached the relevant age. Her bond to him therefore remains Rabbinic. If now accepts from a second man, those -level can take effect even though she still needs a Rabbinic from her first husband. That difference—first bond Rabbinic, second -level—explains the unusual rulings that follow.

Which Minor Requires Mi'un?

Which minor girl requires mi'un to end her marriage?

Not every marriage involving a minor has enough Rabbinic standing to require mi'un. The now defines when a minor's understanding is sufficient for her marriage to require this formal rejection.

From age six through age ten,

we examine her

according to the level of her understanding:

Between ages six and ten, the ruling depends upon her individual level of understanding.

If she knows how to safeguard what she received for her

and understands that it was given to her as ,

The question is not merely whether she can physically keep an object safe. She must appreciate the special significance of what she received and understand that it was given to her for the purpose of .

rather than merely guarding it

-

or something similar—

A young child may understand that an object has value and should not be lost. That alone is not the level of understanding described here. She must recognize the special significance of the object as .

then she requires mi'un;

Her understanding is sufficient for the marriage to have the Rabbinic standing that requires mi'un in order for her to leave it.

-

But if she does not understand how to safeguard her —

she does not require mi'un,

rather, she simply returns to her mother's home

as though she had never been at all.

If she lacks the required understanding of the , she does not need a formal act of mi'un to leave. She simply returns to her mother's home as though no had taken place.

-

If she is younger than six—

even if she knows how to safeguard what she receives,

she does not require mi'un.

Below age six, the rules that mi'un is unnecessary even if she knows how to safeguard what she receives.

-

If she is older than ten—

even if she has very little understanding,

she requires mi'un.

Above age ten, while she remains a minor, the individual assessment of understanding no longer changes this ruling: she requires mi'un.

Whenever her brothers arranged her marriage,

or her relatives,

or her mother,

-

without her knowledge—

she does not require mi'un.

This refers to a case in which her family arranged the marriage without informing her of the identity of the man she was being married to. Because she did not knowingly participate in accepting this marriage, she does not require mi'un to leave it.

Synopsis

Between ages six and ten, whether a minor requires mi'un depends upon whether she understands the special significance of the she receives. Below six, mi'un is unnecessary; above ten, while she remains a minor, mi'un is required even if her understanding is very weak. If her family arranged the marriage without her knowledge, she does not require mi'un.

Picture the CaseA concrete example

An eight-year-old girl is given an item for . The question is not simply whether she knows that the item is valuable and should not be lost. Does she understand that she received it specifically as and recognize what that means? Between ages six and ten, that level of understanding determines whether her Rabbinic marriage has enough standing that she will need mi'un to leave it.

How Mi'un Is Performed

How does a minor girl perform mi'un?

The now moves from defining who is eligible for mi'un to the actual procedure. Mi'un does not require a from the husband; it is accomplished through the girl's own declaration rejecting the marriage.

She says in the presence of two people,

The declaration of mi'un must be made before two people.

“I do not want so-and-so, my husband,”

or, “I do not want the

through which my mother had me ,”

or “my brother,”

or another statement with a similar meaning.

No single formula is required. What matters is that she clearly expresses that she does not want the husband or the through which she was married to him.

Even if the two people were guests seated in her husband's home,

and she was standing there serving them drinks,

The two people do not have to be assembled for a formal proceeding. They may simply be present when she makes her declaration.

-

and she said, “I do not want so-and-so, my husband”—

this constitutes mi'un.

The example emphasizes how straightforward the essential act is. Even while carrying on an ordinary task in her husband's home, a clear declaration before two people that she does not want him is sufficient to constitute mi'un.

Synopsis

Mi'un is accomplished when the minor clearly declares before two people that she does not want her husband or the through which she was married to him. No special formula or formal setting is required; a clear statement expressing her rejection of the marriage is sufficient.

Picture the CaseA concrete example + illustration

Two guests are sitting in a girl's husband's home while she serves drinks. Without any formal ceremony, she says clearly in front of them, “I don't want him as my husband.” That is enough to constitute mi'un.

The Written Record of Mi'un

The two people before whom the minor performs mi'un

The mi'un itself has already occurred through her declaration. The now describes the written record documenting what happened.

“On such-and-such a day,

so-and-so, daughter of so-and-so, performed mi'un in our presence

with regard to so-and-so, her husband,”

and they sign it

and give it to her;

and this is the essential text of a document of mi'un.

Although this document is called a mi'un, it does not function like an ordinary . The girl's spoken mi'un is what ends the Rabbinic marriage; the document records that the mi'un already occurred.

A document of mi'un—

whose delivery effects the divorce,

This is the fundamental distinction between the two documents.

With an ordinary , giving the document to the wife is itself what effects the divorce.

With mi'un, the girl's declaration has already ended the Rabbinic marriage. The written document merely records what occurred.

and it does not need to be written specifically for her sake,

An ordinary has special requirements concerning the intention with which it is written. Since the mi'un document does not itself cause the separation, those requirements do not apply here.

nor does it require formal delivery,

That misunderstanding could lead to incorrect consequences, such as treating the former husband as forbidden to marry her close relatives.

Who Must Know the Girl and Her Husband?

The prohibition discussed in Halachah 12 is not triggered merely because she had relations with someone else while she was divorced.

The decisive factor for this prohibition is , not simply relations with another man.

That explains the contrast:

Divorce → to another man → she may no longer return to the first husband.

Divorce → non-marital relations with another man, without → this particular prohibition against returning to the first husband does not arise.

Since the second marriage was not binding under law, it does not create the prohibition that ordinarily prevents a divorced woman from returning to her first husband. For this purpose, it is as though she had not entered the type of intervening marriage described in Halachah 12.

The marriage itself is not dissolved. Rather, the couple must remain apart for the remainder of the ninety-day waiting period.

and afterward he may live together with his wife.

Once the waiting period has ended, they may resume married life. They do not require new or nisu'in, because their existing marriage was never dissolved.

The three cases can therefore be distinguished clearly:

Nisu'in during the waiting period: the couple are temporarily separated until the period ends, after which they may resume married life.

Synopsis

If a man enters with a woman during her required ninety-day waiting period, he is placed under nidui. If he enters and then flees, nidui is not imposed. If they already entered nisu'in, their marriage is not dissolved; they are separated until the ninety days have ended and may then resume married life without new or nisu'in.

Protecting Another Man's Unborn or Nursing Child

Similarly, the Sages decreed

that a man may not marry

a woman who is pregnant with another man's child,

or a woman who is nursing another man's child,

The now introduces a different protective enactment.

The previous dealt with situations in which a waiting period was needed to clarify a child's paternity. Here, there is no uncertainty about the father. The concern is instead for the welfare of another man's fetus or nursing child.

even though it is known whose offspring the child is.

This phrase makes the distinction explicit. The prohibition does not arise from uncertainty about who fathered the child.

Even when the father is definitely known, prohibited another man from marrying the pregnant or nursing mother because of the concerns that follow.

-

With regard to a pregnant woman—

there is concern that the fetus might be harmed

during marital relations,

for another man's child;

The explains the decree as a concern that the new husband, knowing that the fetus is another man's child, may not exercise the same degree of caution to avoid harming it.

And with regard to a nursing woman—

there is concern that her milk might become impaired,

to restore the milk

if it becomes impaired.

If her ability to nurse is affected, measures may be needed to restore her milk. were concerned that a new husband would not take sufficient responsibility for those needs because the nursing child is another man's child.

Thus, both parts of the decree protect a child whose biological father is not the woman's new husband.

Synopsis

The Rebbe ExplainsWhen halachah calls for medical guidance

When halachah calls for medical guidance

The explains that prohibited marrying a woman who is pregnant with another man’s child partly because the new husband may not be sufficiently careful, and marital relations could harm the developing child.

The Rebbe refers to the ’s teaching that marital relations can have different effects during the various stages of pregnancy: during the first three months they may be difficult for both the mother and child; during the middle months, difficult for the mother but beneficial for the child; and during the final months, beneficial for both. At the same time, the Rebbe notes that in a number of medical matters it has been ruled that physical conditions have changed since the era of the .

The ’s ruling here nevertheless shows that the possibility of harm during pregnancy is recognized in practical and must be taken seriously. The Rebbe therefore concludes that the proper guidance for an individual situation must come from an expert physician. General statements found in sources should not be turned into personal medical instructions without evaluating the actual circumstances.

Weaning the Child Does Not Normally End the Restriction Early

Just as it is forbidden to marry her,

Even if she gave her child to a wet nurse,

during the twenty-four months—

she may not marry.

At first glance, once another woman is nursing the child—or once the child has been weaned—the original concern about the mother's milk appears no longer to apply.

Nevertheless, these steps do not ordinarily shorten the twenty-four-month restriction.

If her child dies—

she is permitted to marry,

Once the child has died, the concern that motivated the nursing restriction no longer exists.

and we are not concerned

that perhaps she will kill him.

Although remarriage becomes permitted if the child dies, did not extend the restriction out of fear that a mother might deliberately harm her child in order to marry sooner.

Synopsis

The restriction on marrying a nursing mother applies even to and normally continues for the full twenty-four months. Giving the child to a wet nurse or weaning him early does not ordinarily permit the mother to marry sooner. If the child dies, however, she may marry; did not prohibit this out of concern that a mother might harm her child in order to remarry.

Picture the CaseA concrete example

A widow has a six-month-old baby and wants to remarry. She arranges for another woman to nurse the baby instead. That does not ordinarily allow her to marry immediately; the twenty-four-month restriction remains. Simply changing who is nursing the child after the father's death does not normally shorten the period established to protect the child.

There are circumstances, however, in which this concern does not apply. The rules that if the child had already been given to a wet nurse during the first husband's lifetime, or if the mother is physically incapable of nursing, she may remarry.

Halachah 27: Don't solve a responsibility by moving it away

The rules that the nursing-period restriction does not normally disappear simply because the child was given to a wet nurse or weaned early. Changing the immediate arrangement does not automatically remove the responsibility that the original safeguard was meant to protect.

Sometimes we do something similar: instead of dealing with a responsibility, we rearrange things until it no longer feels like ours. We mute the reminder, hand off the annoying part, or find a technical workaround. Before doing that, it can be worth asking whether the underlying responsibility has actually disappeared—or whether we have only moved it out of sight.

This is more stringent than violating the ninety-day waiting period discussed in Halachah 24.

Chapter 11 at a glance

From a minor's refusal to safeguards between marriages

The chapter defines the temporary right of mi'un and its consequences, then explains the waiting periods that preserve clear family status and protect an unborn or nursing child.

  • A minor orphan may end her Rabbinically established marriage through mi'un without receiving a . The same applies to a minor whose father originally married her off, if that -level marriage first ended through divorce or widowhood and she then entered another marriage while still a minor.
  • A girl may exercise mi'un only while she retains the status of a minor. Once she becomes a na'arah or is established as an , that right ends. After twelve years and one day, she is ordinarily presumed to have developed signs of maturity; if marital relations then take place, those relations establish -level and mi'un can no longer end the marriage.
  • If a minor's Rabbinic marriage continues until she reaches adulthood without later relations with her first husband, she loses the right of mi'un but requires a only by Rabbinic law. Because the first bond remains Rabbinic, -level from a second man can take effect. The later rulings—including the different status of children from the two men—follow from the distinction between the first husband's Rabbinic bond and the second man's -level .
  • Mi'un is accomplished when the minor clearly declares before two people that she does not want her husband or the through which she was married to him. No special formula or formal setting is required; a clear statement expressing her rejection of the marriage is sufficient.
  • The two people who witness the girl's mi'un write and sign a document recording what occurred. Unlike an ordinary , this document does not cause the separation; the girl's declaration of mi'un already did that. It therefore does not require the special writing, delivery, or wording of a and serves as a legal record of the mi'un.
  • Once a divorced woman becomes to another man, she is forbidden to return to her first husband even if the second relationship never progressed to marital relations. If that second relationship later ends and the first husband nevertheless takes her back and has relations with her, he violates a prohibition, receives lashes, and is compelled to divorce her.
  • Mi'un does not have the status of divorce. If a girl leaves the first man through mi'un, she may return to him even after an intervening marriage ends. But if she left the first husband through an actual , a later mi'un from another husband does not erase the consequences of that original divorce. The key is how she left the first husband before the intervening marriage.
  • A divorced or widowed woman must wait ninety full intervening days before entering new or nisu'in. Neither the day the previous marriage ended nor the day of the new counts toward the ninety days. The waiting period allows any pregnancy from the previous marriage to become identifiable, preventing uncertainty about which husband fathered the child.
  • applied the ninety-day waiting period uniformly, even where pregnancy is not a concern in the individual case or the circumstances strongly indicate that the couple had not been living together. A minor, elderly woman, barren woman, , woman whose husband was absent or unable to be with her, and even a virgin leaving must all wait ninety days.
  • A freed maidservant and a woman who converts are subject to a ninety-day waiting period. Even a husband and wife who convert together must separate for ninety days so that conception before conversion can be distinguished from conception afterward. A yefas to'ar likewise waits a total of ninety days so that a possible conception from the soldier's initial relations can be distinguished from a later conception; the 's thirty-day period is included within those ninety days.
  • If a man enters with a woman during her required ninety-day waiting period, he is placed under nidui. If he enters and then flees, nidui is not imposed. If they already entered nisu'in, their marriage is not dissolved; they are separated until the ninety days have ended and may then resume married life without new or nisu'in.
  • prohibited a man from marrying a woman who is pregnant with or nursing another man's child, even when the child's father is definitely known. The explains that, during pregnancy, the concern is that the new husband may not exercise sufficient caution to avoid harming another man's fetus; during nursing, the concern is that he may not take sufficient measures to restore the mother's milk if it becomes impaired.
