Two credit card companies have put liens on my deceased mother's house in Texas. I would like to sell the house. The house is still in her name. What rights do I have? What can the credit card companies get/do? Is there any way out ?

The liens will have to be paid at settlement was the house is sold. They will release the liens once they receive payment in full.

There is no other option?

Only if you can prove they did not give notice or summon before the judgment was granted.
