Answer: William’s attorney indicated the parties should sign an agreement before the two get married that clearly states the ownership rights each party enjoys in the other party's property. This is known as a:
PRENUPTIAL AGREEMENT.
Explanation: A prenuptial agreement, antenuptial agreement, or premarital agreement (PNA), commonly abbreviated as prenup, is a contract entered into prior to marriage, civil union, or any agreement prior to the main agreement by the people intending to marry or contract with each other.
The content of a prenuptial agreement can vary widely, but commonly includes provisions for division of property and spousal support in the event of divorce or breakup of marriage.
