§ 760.020.Action to Establish Title Against Adverse Claims; Actions By Parties to Agreements Pursuant to Section 6307 Or 6357, Public Resources Code

This is the chapter's core grant of authority. Subdivision (a) lets a plaintiff sue to establish title against adverse claims to real or personal property, or any interest in it — the general-purpose quiet title action most people mean when they use the phrase.

Subdivisions (b) and (c) address a narrower situation: agreements entered into under Public Resources Code § 6307 or § 6357, which let private landowners and the State Lands Commission fix disputed boundaries along tidelands and other state-owned land. Subdivision (b) lets the parties to one of those agreements sue under this chapter to confirm it's valid. Subdivision (c) makes clear that letting the parties confirm their own agreement doesn't shut out members of the public who want to challenge it — the same public-participation protection that § 764.080 later builds into the trial of these boundary-agreement cases.
