Abstract
Let be a definably complete locally o-minimal expansion of an ordered field. We demonstrate the existence of definable quotients of definable sets by definable equivalence relations when several technical conditions are satisfied. These conditions are satisfied when is a locally closed definable subset of and there is a definable proper action of a definable group on .
