A partition action enables you to force the sale of property when coowners are refusing to sell. When two or more people own the same property, one of the owners CAN force a sale of the jointly owned property via a partition action or lawsuit.Most states will utilize both methods. A partition lawsuit can be pretty difficult to stop, though it is not impossible with help from an experienced property dispute lawyer. This is a document through which the parties agree that particular property will be "separate property" and will not be divided.
