Context
An acquaintance rescued a dog that had been abandoned and was looking for someone to adopt her. My wife and I offered to take the dog and find her a home because we were in a better position to care for the dog than this acquaintance was. While filling out some paperwork for a dog fostering program, we encountered the question, "Are you the legal owner of the dog?" I do not know the answer to that question.
Question
What constitutes legal ownership of a dog in Utah? Is there paperwork or registration that needs to be filled out to become the legal owner? Or do you become the legal owner once you claim the dog (and no one disputes the claim)? Or does taking care of the dog long-term make you the legal owner even if you don't claim ownership? Or is it something else?
