I loan my son in law (now ex son I law) money to payoff some high interest loans he had a couple of years ago now that my daughter and him have split he has stop paying me back.
My question is can I take the remaining amount owed and take it off as a loss on my 2015 taxes? And what do I need to support this in paper work for the IRS.
I got his name, SSI number and other information as I did his taxes last year.

Thanks,
