What do the letters “L.S.” mean on a signature line on a document?
The Latin phrase logus sigilli means “place of the seal.” You may see the letters at the end of a signature line for the document signer or for the notary. Although rarely done, a person may use a private seal to authenticate his or her signature. More commonly, a corporate seal may be affixed next to the officer’s signature when he or she signs on behalf of the corporation. When affixing your notary seal, take care not affix the seal over these letters, or any other writing.
