A more thorough explanation: In legal terms, a seal refers to a formal mark or symbol affixed to a document to signify its authenticity and to indicate that the document has been executed with the intention of creating a legally binding agreement. Seals were historically used as a form of signature, but in modern times, they are often replaced by signatures or other forms of authentication.
Example: The parties agreed to seal the contract with their signatures.
