Can the property management contract be signed by the lessee and the property management company?

No, the property management company can only sign a property service contract with the owner. Property management regulations have clear provisions. Don't say renter, for example, only your name is on the real estate license. You and your wife live in a community, and your wife is not qualified to sign a contract with a property management company. Similarly, your wife is not qualified to participate in the owners' Committee.
