I am so sorry to hear about this...I'm assuming that the house was sold at sheriff's sale, the sale was confirmed, and the sheriff evicted you or the tenants. I find it hard to believe you would have had no notice. This is a long process and you should have received a whole lot of paperwork over several months. If all of this has taken place, then you likely have no rights to your property. I would suggest contacting the sheriff or the new owner to see if they will allow you to go get your stuff. Outside of their permission, you're out of luck.
