Quick answer

Unclaimed oil and gas royalties in California are held by the California State Controller's Office — Unclaimed Property Division; search its official site, claimit.ca.gov, under every name the royalties may have been paid to. California presumes unpaid property abandoned after 3 years (Cal. Code Civ. Proc. § 1520(a) (general rule)), and the holder must then report it to the state.

## When unpaid royalties are presumed abandoned

California has no separate statutory period for mineral proceeds; intangible property held in the ordinary course of business escheats after more than three years unclaimed. The Controller's dormancy table lists every mineral code (net revenue interest, royalties, overriding royalties, production payments, working interest, bonuses, delay rentals, shut-in and minimum royalties) at three years.

**Dormancy period:** 3 years

**Statute:** Cal. Code Civ. Proc. § 1520(a) (general rule)

**Mineral-specific rule:** No (general period)

## How operators report unclaimed royalties

California uses two reports: holders file a Notice Report before November 1, as of June 30 or their fiscal year-end, then remit unclaimed property later with a Remit Report after the Controller has notified owners. Life insurers file before May 1 as of December 31.

**Report due:** Notice Report before November 1 (life insurers before May 1); property is remitted later with a separate Remit Report

**Covers property held as of:** June 30 or fiscal year-end preceding (life insurers: December 31)

## How to claim and what proof you need

California claims start on the Controller's claim site, and eligible claims can be filed electronically. The documents that go with the signed Claim Affirmation Form depend on whether the claimant is the owner, an heir, or a business or government agency.

**How to file:** Search and file on the Controller's claim site. Eligible claims are offered electronic filing after the claim details are entered; if a paper claim is required, the site gives instructions for it.

**Proof required:** Depends on who is claiming (owner, heir, business or government agency); the Controller's filing instructions list the documents to send with the signed Claim Affirmation Form.

## Claiming for a deceased owner

An heir, trustee or personal representative can claim a deceased owner's property. Heirs must provide certified copies of documents such as a will or trust showing they are entitled, and fill out additional Controller forms if there is no will or trust.

**Documents:** Heirs, trustees or personal representatives/executors/administrators may claim; heirs provide certified copies of official documents such as a will or trust showing entitlement; if there is no will or trust, additional forms are required. The Controller verifies mainly by Social Security number and asks for the extra documents in the filing instructions when the holder did not report one.

Whether an estate must be opened is a legal question for a qualified attorney in that state.
