a good start would be to go to the lands registry to find out under whose name the title is held right now. it might not even be the father of your ex...
Called my wife and she told me where I could possibly find the deed to the house. Dug around for about an hour and I have found it, but it looks like it's still in her grandmother's name. Her grandmother died way back in 99. So any advice on what I do now?
I've paid everything that needs to be paid while living here.
