A partition is a term used in the law of real property to describe an act, by a court order or otherwise, to divide up a concurrent estate into separate portions representing the proportionate interests of the owners of property. It is sometimes described as a forced sale. Under the common law, any owner of property who owns an undivided concurrent interest in land can seek such a division. In some cases, the parties agree to a specific division of the land; if they are unable to do so, the court will determine an appropriate division. A sole owner, or several owners, of a piece of land may partition their land by entering a deed poll.
