This topic investigates the previous property management contract. The Contract Law stipulates that the parties may stipulate that the validity of the contract is subject to conditions. A contract with effective conditions shall take effect when the conditions are met. A contract with termination conditions is invalid when the conditions are met, and the previous property service contract is a contract with termination conditions. "Property Management Regulations" stipulates that if the property service contract signed by the owners' committee and the property service enterprise takes effect before the expiration of the time limit, the previous property service contract will be terminated. Therefore, the term of the previous property management contract is uncertain, and the property service enterprise may be dismissed by the owners' meeting at any time.
