Your brother's wife is your sister-in-law.

Yourself

Assuming the brother who died with a will was unmarried and had no children, and assuming his beneficiary brother predeceased him, his estate would pass to the children of his siblings. If he had only one brother then his brother's children would inherit his estate.

At certain points your friends will ignore whatever your brother because he is your brother but if your brother crosses the limit then your friends will never forgive him. Try to tell your brother that he is making a mistake

It gets a bit tricky so I'll try my best...Brother in Samoan is "uso"..but that's only if you're a male referring to his brother. A female would refer to her brother by calling him her "tuagane". A female would refer to her sister by calling her her "uso". Hope that helps.
