A partition action is a lawsuit in which a court determines whether a property with two or more owners is to be partitioned or sold. A Partition is a type of lawsuit where a judge, or a court-appointed master will hear evidence and determine whether the property is to be divided or sold.A partition action enables you to force the sale of property when coowners are refusing to sell. The document is a partition agreement between two parties to terminate their community ownership of a parcel of land and divide it between them. Everything you need to know to successfully litigate a land partition action is contained in the Pennsylvania Rules of Civil Procedure. 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. If division is not practical (for example, in the case of a single-family home), the court will order the property to be sold and the proceeds distributed.
