Nothing, your husband's brother is your brother in law but his wife isnt related
ya mum!
no
Yes, certainly it is acceptable. As a wife you can choose your husbands clothes for him.
NO. any person who is truly professional does not mix work with relationship. even if his wife is his PA they should have ONLY a professional relationship at work.
its romantic
Your younger brother's wife's sister's daughter would be your son's cousin.
Your mother's brother is your uncle. Your father is your uncle's brother-in-law. But your uncle could have other brothers-in-law. These would include the husbands of any sister's your mother might have (also your uncles), as well as the brothers of of your uncle's wife, if she has any. The brothers of your uncle's wife are not related to you.
Yes a wife has monetary rights to her husbands home in a divorce.
They are brothers in law
Sisters-in-law, assuming that they are otherwise unrelated. In a small town, it's entirely possible that your wife and your brother's wife might be cousins of some degree.
You are your brother's wife's brother-in-law, if you are male. But your brother's wife can also have brothers-in-law who are not related to you or to your brother. They would be the husband's of the wife's sisters.
My wife says "cuz husbands usually deserve it".
