Does the buyer's signature in the second-hand house property sales contract have anything to do with whose name is written on the real estate license? For example, the real estate license will write the man's name in the house purchase contract. In the future, the real estate license will write the man's name. Should the house purchase contract be signed by the man's name or by both husband and wife?

Your understanding is wrong.

The correct explanation is: in the purchase contract, the buyer is a person, and the real estate license is issued as a separate ownership, and the signature is signed by him alone; There are two property buyers and two real estate licenses, which are called * * * and * * * (they can be husband and wife or relatives and friends). There is no limit on the number of buyers in the same suite, and as many buyers as there are, how many real estate licenses will be issued.
