Got a deed for collateral

[Chip Chronister]

There is a house that was sold at a tax sale and I gave the couple a small loan so they could pay the taxes on the house and redeem it back, she claims that she did this but the man who bought it at a tax sale filed a deed in 17th of July and I got them to sign a quit claim deed the 20th of June.

Now the couple will not pay what they owe me and I would like to file the deed and evict them and take the house. Will I be able to file the quit claim deed and get the house or how should I go about getting the house.

Thanks
