The Affidavit of Labor is a Bureau of Land Management (BLM), California State Office form on which a claimant swears that the labor and improvements required by law were performed on one or more contiguous mining claims during the mining assessment year ending September 1. The Riverside County Assessor-County Clerk-Recorder publishes it among its Recorder Sample Documents. It records assessment work on mining claims, so it is not a bill or payment form for Riverside County property tax.

What is Affidavit of Labor – Riverside County, CA?
The Affidavit of Labor is a two-page notice, issued under the U.S. Department of the Interior's Bureau of Land Management (BLM), California State Office, in which the people responsible for one or more mining claims certify under penalty of perjury that required assessment work was done during the mining assessment year ending September 1.
The form is built around five numbered statements:
- 1. The claims worked, listed as a group of contiguous claims, with the county, the claim name, its location (S/T/R/Mer.), the original CAMC number, and county recordation and amendment data.
- 2A and 2B. The type of labor and improvements, with a description and value for each, and the date(s) the work was performed.
- 3. The name(s) and address(es) of the people who performed the labor.
- 4. The name(s) and address(es) of the people who hold and claim the mining claim(s).
- 5. A statement that, on the original location date, the required monuments were erected, the required notices were posted (or copies were in place), and each corner monument was marked to designate the corner and the name of the claim.
The header also has a line for the number of claims and the total due to BLM, and a box marked "Tax Collector Use" beside the total value. The form states that it exists to comply with federal and California law on assessment work (30 USC 28, 43 CFR 3833.2). The original notice is filed with the county recorder and a duplicate with BLM.
It is a mining-claim document. It is not a property tax return, bill or payment form. The county's forms page adds that its staff cannot give legal advice or help prepare legal documents.
Who needs to file Affidavit of Labor – Riverside County, CA?
The form is for the people who hold and claim one or more mining claims and who are responsible for the statements in the affidavit. Item 4 asks for the name and current mailing or residence address of each person who holds and claims the claim(s) for the valuable minerals in them, and the signature line is for the "person(s) responsible for above statements."
- Claimants with several claims. The form is written for a group of contiguous claims, with room for several claims on one sheet. If you need more space, the form says to use a supplemental sheet.
- Whoever did the work. Item 3 asks for the name and address of each person who performed the labor and improvements, who may differ from the claim holders.
- Surveys. If a geological, geochemical or geophysical survey was part of the work, item 2A asks you to reference the report's title, cost and date and to indicate that it was filed with the County Recorder.
Anyone who willfully makes a false statement about a mining claim on the affidavit or on the supplementary affidavit is guilty of a misdemeanor under Public Resources Code of California, Div. 3.5, Chap. 1, Sec. 3913c,d. The county's forms page states that its employees cannot provide legal advice; for questions about whether this is the right document, consult an attorney or other professional.
When to file Affidavit of Labor – Riverside County, CA
The form is tied to the mining assessment year ending September 1, which the form prints in statement 1. File the original notice with the appropriate county recorder by September 30, and file a duplicate notice with the Bureau of Land Management, California State Office, by December 30.
Item 2B asks for the month, day(s) and year the assessment work was performed, so the work comes first and the affidavit follows. The form sets no other date or renewal cycle. Statement 5 refers to the original location date of the claim, which you enter from your claim records.
Because the affidavit is signed under penalty of perjury, check the work dates, values and claim details before you sign and file.
Documents you need
- A duplicate of the notice, filed by December 30 with the Bureau of Land Management, California State Office; the original goes to the county recorder.
- A supplemental sheet, only if the claim table in item 1 does not have enough room for all of your claims.
- The report of a geological, geochemical or geophysical survey, only if such a survey was part of the work; item 2A asks for its title, cost and date and for an indication that it was filed with the County Recorder.

- Entering a total value of labor and improvements below the minimum the form prints for each claim in item 2A.
- Writing in the "For Recorder's Use Only" area or the "Tax Collector Use" box, which are not for the claimant.
- Leaving out the survey report details in item 2A when a geological, geochemical or geophysical survey was part of the work.
- Signing without checking the statements: a willful false statement about a mining claim is a misdemeanor under Public Resources Code Sec. 3913c,d.
- Submitting the form online or by an electronic channel, when the county says its forms must be delivered by mail or in person.
