∙ 13y agoYour sister-in-law may be the wife of your brother. If so, her daughter is your brother's daughter and your niece. You are her aunt or uncle. If your sister-in-law has a daughter fro a previous marriage, that daughter is not related to you unless your brother adopts her; then she is your niece.
Your sister-in-law may also be the sister of your spouse. In that case her daughter is your spouse's niece, and, because you are married to your spouse, your niece, too. In the English-speaking cultures, you and your spouse are her aunt and uncle. The concept of "in-law" is not used when discussing this relationship.
