In practice, if a contract is signed without a seal, the parties can prove it in other ways, such as providing emails, text messages and other documents related to the contract, or issuing a written statement to prove the true wishes of the party. At the same time, when signing a contract, the parties can agree on matters such as the method and time of sealing or signing to ensure the evidentiary strength and enforceability of the contract.
