In Law, Estray means a valuable domestic or tame animal that is found wandering and ownerless. It can be an animal that has escaped from its owner-a stray and unclaimed domestic animal. The general rule now is estray animals passes to the state in trust for the true owner, who may regain it by proving ownership. However an animal which is on the range where it is raised and where its owner permits it to run cannot be considered estray. It does not amount to estray when the owner is known to the party who takes the animal.
