My friend used to own property along with his wife. They have since divorced and was looking to see if his name was still on the deed. Is there anywhere he can find out online a registrar of property deeds?

I live in Travis County Texas. I own a property and would like to buy the adjacent lot. I only wish to do so if I can refinance my existing home to include the adjacent lot, which I can only do if they are joined under a single deed. Is it possible and if so, how does one go about this? The county clerk is telling me it's not possible but I can't understand why.

My father in law has recently died, his will states that he leaves his share of their property to his wife. Is it neccessary to have his name removed from the deeds?
