In my country when two people want to get married they set an amount of money that if they want to get divorced the husband must give that money to his wife. I wanted to know if there is any specific word for this money in English Thanks in advance.
I do not know a word for the sum of money itself. But a prenuptial agreement (or prenup informally) is a legal agreement entered into prior to marriage. It can specify how property is divided in the case of a divorce.
