Neighbour has moved house and refuses to give spare key to my house back!
Just that really. He had been doing some work in the house but it's finished now, and I let him keep the key in case I locked myself or needed a spare for whatever reason.
So obviously I asked him for the key back when he moved last week (so that I can give it to his landlord, who is moving back into the property), and he refused! I'm just waiting for something to complete that he's helping me with, then I will take action. I'd rather not have to change the locks. Is he breaking any French law by refusing to return the key?
Also, I read somewhere that leaving a key with a neighbour could invalidate house insurance, is that true?
