Mt father-in-law lives in South Carolina and wants to visit his daughter (my wife) and his grandchildren. He's handicapped and unable to drive and he plans to stay with us for about a week. A relative of his (and I guess, us, through marriage) has offered to drive him here but this relative is a convicted felon. I remember hearing or reading that it is illegal for a convicted felon to stay at a property where there are firearms.

So my question is: Can we legally have this convicted felon stay in our home for about a week while my father-in-law visits or do we have to put him up in a motel or some other place that doesn't have firearms?

Thanks in advance for help.
