Hello, legal analysis: Is it useful for a rental contract to be signed by both spouses: Yes, as long as it is signed by one spouse. Because it is signed by the spouse, it has certain validity from a legal perspective, but it is best to have the property owner's spouse indicate on the contract that the property owner has agreed. But it is best to have a power of attorney. The house rental contract signed with either spouse is valid. Because both husband and wife own property and have equal rights to dispose of it. Husband and wife have equal rights in handling property owned by the husband and wife.
