I don't know much about divorce, but I would sell the guns to a person I trusted (mother, brother, sister, father, really close friend, ect) and then buy them back after the divorce was all said and done. If Kentucky laws are like Texas laws, then you can just sell the gun with no paperwork. That means that he (or the court) would not be able to track the guns down or even prove they exist.
I am not a lawyer, or anything like that. This is just what I would try to do. You should also talk to your lawyer.
Sorry about the divorce.
