I am a retired lawyer from Texas. I had a German client, who emigrated after WWII, who was contacted By a distant cousin to sign a deed because heirs were trying to sell a small apartment building in Dresden. We hired a very large international law firm with offices in Germany. Since they were an american firm, they had ethical duties to worry about.
so, search for a large international law firm in the same area as the property and write to see what they can do. They should charge a small retainer to check into it. If they can get something for you they will ask for more money. They probably will not work on contingency, as that is rare overseas. If they think it is a bad case, they should say so. Important that they have offices in US to protect you in case of trouble. Good luck. We got net of 200,000 dollars for her one sixty fourth share.
