Legal documents requiring a signature sometimes also contain the word Seal, seal in brackets [Seal], or the Latin words, Locus Sigilli or [L.S.] near the signature line. This may refer to a private seal or personal seal, such as a rubber ink stamp, or an embossed seal, a corporate seal, a government seal or a notary seal. So does placing “(Seal)” next to the signature blocks on a contract actually make a contract enforceable for a longer period of time? The answer depends on which state’s laws govern the contract. In Maryland and Virginia, adding that single word does not itself extend the enforcement period. That is, it gives a party 20 years (essentially beginning with the date of the signature) to assert claims against you as to the transaction or contract covered by your signature. And, on the flip side, it gives you 20 years for you to assert claims against the other party if that party also also signed under seal.
