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 (sometimes referred to as "carving out").

Waste is a term used in property law to describe a cause of action that can be brought in court to address a change in condition of real property brought about by a current tenant that damages or destroys the value of that property. A lawsuit for waste can be brought against a life tenant or lessee of a leasehold estate, either by a current landlord or by the owner of a vested future interest. The holder of an executory interest, however, has no standing to enforce an action for waste, since his future interest is not vested. There are several different kinds of waste under the law.
