If someone thakes something thats not theres and it blong to there dead husbands child can that child get it back if so how

I suggest you visit a local probate attorney. Through probate you can retrieve your inheritance. To get your stereo back you can file a tort action for trespass of chattel or conversion, and you can probably do so in small claims court if the value of the system was under the Kentucky max for small claims.

Yes-it is possible through the probate court. You should see an attorney.
