Is your sister-in-law's brother your brother-in-law?

Answer:
Your brother-in-law is the brother of your spouse or the husband of your sister.

If your sister-in-law is the sister of your spouse, then her brother is your brother-in-law, unless you are a female, in which case he might be your husband. If your sister-in-law is the wife of your brother, her brother is not related to you
