Marrying Your Brother's Widow: Is It Allowed?

A sibling-in-law is the spouse of one's sibling or the sibling of one's spouse. In the context of a man marrying his sister-in-law, it is understood that the sister-in-law in question is the wife of the man's sibling, making her the man's sister-in-law by marriage, not by blood. While such a union is uncommon, there do not appear to be any legal impediments to it, as the relationship is not one of those prohibited by kindred, consanguinity, or affinity.

Can a man marry his sister-in-law?

A sibling-in-law is the spouse of your sibling

In Indian English, the spouse of your sibling may also be referred to as a co-sibling. A co-sister refers to the wife of one's sibling-in-law, and a co-brother refers to the husband of one's sibling-in-law.

The children of your siblings-in-law are called nieces and nephews, and if necessary, it can be specified whether they are "by marriage", "by blood", or "by adoption". For instance, if your sibling marries someone with children, those children become your nieces and nephews by marriage.

It is important to note that in many cultures and legal systems, marrying one's sister-in-law, or brother-in-law, is prohibited due to the close degree of kinship. This is true for both men and women.

A man cannot marry his sister by blood

Now, let's talk about the term "sister-in-law". A sister-in-law is the wife of one's sibling or the sister of one's spouse. This relationship is reciprocal, meaning it goes both ways. So, if you are a man and you are married, your sister-in-law could refer to your spouse's sister or the sister of your spouse. This relationship is not a blood relationship but one of "affinity" or "alliance".

It is important to note that the laws and cultural norms regarding marriage and kinship terms can vary across different countries and cultures. In some cultures, there may be exceptions or specific circumstances where a man can legally marry his sister-in-law, especially if they are not related by blood. However, it is always essential to respect the laws and cultural practices of the respective society.

In general, the concept of a "sister-in-law" is a way to refer to individuals who are considered family through marriage, as opposed to blood relations. This distinction is important in maintaining the integrity of family structures and avoiding prohibited marriages, such as those between blood relatives.

In conclusion, a man cannot marry his sister by blood due to legal and ethical prohibitions against incest. However, the term "sister-in-law" refers to a relationship by marriage, which is distinct from blood relationships and carries its own set of cultural and legal implications.

In Indian English, a sister-in-law can be called a co-sister

In most cultures, a sibling-in-law is the spouse of one's sibling or the sibling of one's spouse. In other words, it is a relationship by marriage. Commonly, a male sibling-in-law is referred to as a brother-in-law, and a female sibling-in-law is called a sister-in-law. However, in Indian English, a sister-in-law can also be called a co-sister, specifically referring to the wife of one's sibling-in-law. Likewise, a co-brother is the husband of one's sibling-in-law. These terms are used to describe the reciprocal relationship between a person's spouse and their sibling's spouse.

The children of one's siblings-in-law are called nieces and nephews, and if necessary, the relationship is specified as "by marriage", as opposed to "by blood" or "by adoption". For example, if one pair of siblings marries another pair of siblings, the siblings-in-law are doubly related, with each of the four being connected through their spouse and their sibling. In this case, the children of the two couples are double cousins.

In-law relationships are a type of kinship called affinity, which does not relate to the person directly by blood. This is in contrast to relationships that are "by blood" or "by adoption". In some cultures, there are specific customs and laws surrounding relationships and sexual relations with siblings-in-law. For instance, in Judaism, there was a custom called yibbum, where a man had a non-obligatory duty to marry his deceased brother's childless widow so that she could bear his children. On the other hand, Islamic law (Sharia) and Jewish law (halakha) prohibit sexual relations between siblings-in-law as incestuous unless the spouse is no longer married.

A man can marry his former sister-in-law if she was previously married to his brother

A man's sister-in-law is the wife of his sibling. This relationship is not one that is directly related by blood, but rather by affinity, or through marriage. Therefore, if a man's brother were to pass away or divorce his wife, the man would no longer be related to the former wife of his brother. The former sister-in-law would no longer be the man's sister-in-law, and there would be no legal or biological reason why the man could not marry her.

In some cultures, the terminology differs. In Indian English, for example, the wife of one's sibling-in-law is referred to as a co-sister. This is a more specific term that differentiates the relationship between the man and the wife of his sibling, and the relationship with his own sibling.

There are, of course, cultural and religious taboos surrounding such a relationship, and it may be considered unusual or unacceptable in certain societies. However, legally and biologically, there is no prohibition on a man marrying his former sister-in-law, provided she was previously married to his brother.

It is worth noting that, in some jurisdictions, there are laws that prohibit marriages between certain relatives, including relationships by affinity. These laws may vary, and it is always important to refer to local legislation and legal advice.

A man cannot marry his brother's wife

In simple terms, your sister-in-law is your sibling's spouse. So, if you were to marry your brother's wife, she would simultaneously be your sister-in-law and your spouse, which is not permitted. This is similar to how a woman cannot marry her brother's son, or her nephew, as he is her son by affinity or alliance.

In some cultures, there are different terms to describe these relationships. For example, in Indian English, the wife of your sibling's spouse (your brother's wife) would be referred to as a co-sister. This is a more specific term to describe the reciprocal relationship between a person's spouse and their sibling's spouse.

It is important to note that these marriage restrictions are based on cultural and societal norms and may vary depending on the legal system and geographic location. However, the concept of a "sister-in-law" as a prohibited marriage partner for a man is widely recognized and falls under the category of prohibited degrees of kinship in many legal systems.
