How sad. Not being a lawyer like MeganS

, I'm not sure of the legal ramifications. I would think any kind of paper trail outlining the agreement would help in small-claims court. Or if you could get them to admit the agreement and record the conversation.
However, as sad as it is for your mother, it's probably best for the dog to go back to its original owner.
