locus sigillithe place to which the seal is affixed on legal documents.
LOCUS SIGILLI. The place of the seal. 2. In many of the states, instead of sealing deeds, writs, and other papers or documents requiring it, a scroll is made in which the letters L. S. are printed or written, which is an abbreviation of Locus Sigilli. This in some of the states has all the efficacy of a seal, but in others it has no such effect. See Scroll.
