Renter signed lease, paid deposit and rent, wants to back out

[Matthew T.]

Hi all. The title is pretty self explanatory. I have a renter who signed a lease last week. Paid deposit and first months rent. Didn’t move in. Now he wants out of the lease and wants their money back. According to him he is in a custody legal battle and his lawyer said he can’t move. He hasn’t proven this and I don’t think is entirely true. 

I did run background checks on him, and I found court records of child support, but according to those records it was dismissed. 
I didn’t know he was in a custody legal battle because he had specifically told me his ex-wife was out of the picture and didn’t want anything to do with their kids when I brought up those records. Now he is telling me the opposite. 
I’m located in Kansas. 
Thanks.
