Sister-In-Law has our stuff and won't give it back, what do we do?
About 2 weeks ago my sister-in-law's boyfriend borrowed $60 from my husband. They refused to give it back and an argument insued. While from this sprouted the fact that my husband has a little girls scooter and some speakers of theirs, and they have my husbands $100+ tools and our tent. We have been trying since to set up an "exchange" to give them their stuff and get ours back. They keep on stalling though. Both of them have a reputation of pawning stuff so we think that may be what they did. We have reciepts showing that the tools are outs (not the tent though). We told them that if we don't get our stuff soon we are going to call the cops. They keep saying that won't do us any good cause we have their stuff too. However we have text messages of this whole endeavor and from those proof that we have been nothing but cooperative and TRYING to give them their stuff (though there have of course been some nasty words exchanged). What legal grounds do we have to get our stuff back? PLEASE ONLY PEOPLE WITH EXPERIENCE IN LAW OR LAW ENFORCEMENT! No offense to anyone just want to make sure we have our ducks in order here.
