Legal Question in Civil Litigation in Michigan

Re: Return of engagement ring and return of famly dog

You're probably out of luck on the engagement ring. That would arguably be considered a gift over which you would have no claim of ownership. As far as the dog goes, legally your best bet is to file a small claims action for what is called conversion. Conversion is wrongful appropriation of someone else's property with the purpose of assuming ownership of it. What you're going to have to establish is that you indeed owned the dog as an individual and not jointly with your fiance'. Good luck to you, I'm sure this is a pretty tough situation to be in.
