Ok so I answered all that above.
The quit claim deed is still valid, and it is valid from the date it was executed. The date that it is registered is not the valid date. That just registers the date that the deed was dated. So his transfer actually happened before the lien. So you can't contest the quit claim deed.
If you gave him a lien with a loan in your name, that will be an issue for the bank, once they find out. Technically you aren't allowed to transfer your interest if you have a mortgage in your name.
Although a lien does give the state certain ownership rights, it isn't full ownership, because the owner still has the right to pay them the back taxes. Once it is redeemed the state ownership no longer exists, so it is a temporary right, sort of like a mortgage, rather than full ownership rights.
I understand that you want to reverse this, but unfortunately this is not fraud. Someone can hold onto a deed for a long time before filing it and it is still valid. The issue is really that you were not supposed to have done a deed if you had a mortgage. So you are still liable on the mortgage, even though your name is ***** ***** the deed.
Let me know if this is clear.
