How do I get a joint owner removed from the property

You will simply have to confer with an attorney about this in person. Whether this is an option at all depends greatly on the specific facts in your situation. If you both are title owners, absent other circumstances, you both have the right to possession. In fact, forcing the other person to leave may result in liability (unless there is a lawful option.) I am sorry that there isn't a simple answer here. There may be many options depending on the facts, but you will have to meet with an attorney to discuss those options.
