I had offered my future brother-in-law and his girlfriend my old wedding set to use for their new engagement. This was a verbal agreement between both of them ,with me, that they could have these rings (engagement/wedding band) for the price of $2,000.00. At the time they were in the process of moving into a new house, which needed some work done, so I advised both of them that they didn't need to pay me right away for the set. Since then they have broken off the engagement and planned wedding, and now he is living with us. She has been difficult with this transition from the beginning of the break-up. She is now threatening to keep this set of rings without paying me for them. Is there some legal advise you could give me as to how I could go about getting those returned to me..Thanks for your time!
