Related Terms: Lex Loci Contractus


  • locum or
  • loci.

In Sweet & Maxwell's anonymously-authored, 1960 book Latin for Lawyers, at page 264, this:

"Locus: place."

Locus typically forms part of other Latin maxims or phrases such as:

  • Lex loci (the law of a place);
  • Lex loci contractus (the law of the place of the contract)
  • Lex loci delecti (the place of the wrong);
  • Locum tenens (temporarily holding an office);
  • Locus criminis (the place of the crime);
  • Locus publicus (a public place);
  • Locus regit actum (the place where the facts occured);
  • Locus sigilli (the place where the seal was apposed);
  • Locus standi (legal standing); and
  • Ratione loci (by reason of the place).

Or lawyers talk of the locus delicti as the place where a criminal offense was committed or in loco parentis to refer to a person who stands in the place of a parent such as a step-parent in a common law relationship.
