Is a stepmother your mother-in-law

Answer 1

If (as a man) you married your sister-in-law's sister then her mother is your mother-in-law.

If (as a woman) you married your sister-in-law's brother then her mother is your mother-in-law.

If your sister-in-law married your brother then her mother is not your mother-in-law.

Answer 2

If your wife and your brother's wife are sisters, then your mother-in-law is also your brother's mother-in-law.

Otherwise, your brother's mother-in-law is notyour mother-in-law. In fact, she is not related to you at all.

Answer 3

If you are living as a minor with your father and your step-mother, she is part of your nuclear family, not your extended family. If you are living with your spouse and your minor children, then your step-mother is a member of your extended family, as is your father and your mother, even if they are also living with you.

Answer 4

No, just your stepmother. Your mother-in-law is your husbands/wifes mother.

Answer 5

If your father is married to a woman who is not your mother, this woman is your step-mother.

If you are married, the mother of your spouse is your mother-in-law.

Answer 6

No, your mother-in-law is your husband's mother.
