Locus Sigilli Law and Legal Definition
Locus sigilli is a phrase that is most often abbreviated as “L.S.” “Locus sigilli” is a Latin phrase meaning “the place of the seal.” These traditional letters appear on the notarial certificates to show where the notary public’s embossed seal should be placed or fixed. In case of a rubber-stamp seal; the seal should be placed near the abbreviation “L.S.” but, not over it. This may also be used to indicate the signer, the place for fixing his signature. While a contract under seal was a formal contract at Common law, anything indicating a seal served the purpose under Modern law. However, pursuant to the Uniform Commercial Code, the use of seal is inoperative in a contract for sale of goods.
