Tax Deed Overages - I found an owner who is due money!

[Seung Lee]

I found an owner of a house who is due the overage.  I did a bit of research and the house was deeded to 3 people, her, her mother, and her step father.  Her mother is deceased. Her step-father left the country long ago and no one has kept in touch with him.  I am speaking with the daughter.

Assuming that the overage amount is $10,000.  How much is the daughter able to claim? Does she have to do anything to show that her mother is deceased?  Or if she makes the only claim, does she get everything as long as no one else makes any claims to it?  

Thanks for your help.
