Legal Question in Real Estate Law in Georgia

We don't know how the house was treated in the divorce and settlement documents. Obviously, it should have been decided then and it is likely costly to have not dealt with it then. One option is the one you did not mention - contact your ex to resolve the issues, whether it is to continue renting or sell, or one of you buying out the other. That is what business partners do (except most have contracts to cover this - they don't just buy a hose together without smart planning). What will likely cause more harm than good is you interfering with the tenants.

You say "ex." In a divorce, you were required to disclose the real estate, and divide it in the divorce. What does the divorce say? Assuming you didn't do something completely goofy and do a divorce without a lawyer, the answer is in your paperwork, and you didn't tell us what it said.

Be prepared to go to court AND hire a lawyer to represent you if you are looking for that rent money or for control of "your half" of the home.

Good luck.
