Party Walls and Boundary Agreements


Matthew Bender Editorial Staff

Chapter Summary


This chapter discusses party walls and boundary agreements. The law of party walls relates essentially to the law of easements and to the right of support by adjoining landowners in a common wall located on or near the line of division between their properties. The law of boundary agreements relates to the procedure by which an uncertain boundary line between adjoining lands is defined and fixed, with the agreed boundary attaching to the deeds under which the adjoining owners claim title. The chapter's research guide contains the California statutes relevant to these topics.

The chapter's legal background section defines a party wall, discusses how an agreement for a party wall creates an easement appurtenant, and distinguishes a party wall from a partition fence. It further explains the creation of a party wall by deed, implication, and agreement, which is the most common method. In addition, the section covers the scope of the party wall easement, modifications to the party wall, and the allocation of construction and maintenance costs for the party wall.

The legal background also examines boundaries and the methods by which they may be located and established. This section describes the creation of boundaries by a written description in a deed, by agreement, by estoppel, by adverse possession or prescriptive easement, or under the Cullen Earthquake Act if boundaries have been disturbed by earth movements. It provides details on the doctrine of agreed boundaries and the requirements for boundary agreements. Finally, the legal background discusses the natural-accretion rule and the artificial-accretion rule with respect to the ownership of land that accretes by natural or artificial means.

The chapter's transaction guide provides facts and documents needed regarding the landowners and the property in order to draft party wall or boundary agreements, as well as a procedural guide for the execution, acknowledgment, and recordation of party wall and boundary agreements.

The forms section contains party wall agreements, a grant of a party wall easement, and boundary agreements.
