My wife's brother needs a place to stay and we were planning to let him stay with us for a while. He informed me that he is currently on probation and his probation states that he can not have access to firearms at any time, if he gains access to a firearm he will be in violation of his probation.

I have firearms in my home and they are locked up in a safe that he will not have access to. Does keeping my firearms locked up in a safe meet the requirements of him not having access to a firearm?
