Tenants in Common

[Mike]

My name was put on a quit claim deed along with someone else I don't know and placed as tenants in common by my dad who passed away. The quit claim was on property that was auctioned off without my knowledge and I received half of the interest on the property. The other party on the quit claim deed was deceased and I'm assuming someone in her family will get her part. My question is that noone has been able to claim her part of the interest and wanted to know then where would the rest of the interest go? Thanks.
