California real estate forms fall into a predictable stack: the purchase contract, a set of state-mandated seller disclosures, a federal lead-paint disclosure for older homes, agency relationship forms, lender-issued loan disclosures, FIRPTA paperwork when the seller is foreign, and the deed and change-of-ownership report filed at closing. Some come from statute, some from federal law, and most of the transactional paperwork comes from the California Association of REALTORS (C.A.R.) forms library. Missing even one required disclosure can give a buyer the right to walk away or expose a seller to liability after closing.
The Residential Purchase Agreement
The Residential Purchase Agreement (RPA), published by C.A.R. and updated regularly, is the contract that sets the entire transaction in motion. It spells out the purchase price, how the buyer plans to finance it, the size of the earnest money deposit (typically one to three percent of the price), and the timeline for every major milestone from inspection through closing. The RPA also doubles as joint escrow instructions, so escrow can close without a separate instruction letter.
The contingency clauses built into the RPA are what protect the buyer during due diligence. A loan contingency gives the buyer a set window to lock down financing; if the lender falls through inside that window, the buyer can cancel and recover the deposit. Inspection and appraisal contingencies work the same way, each with its own deadline. Once a contingency period expires without cancellation, the buyer loses that safety net.
Liquidated Damages and the Deposit
The RPA includes an optional liquidated damages clause that both parties must separately initial. If the buyer defaults after removing contingencies, the seller keeps the deposit as pre-set compensation rather than suing for actual losses. California law caps that amount: for owner-occupied homes of four units or fewer, a liquidated damages provision is presumed valid only if the amount does not exceed three percent of the purchase price. Above three percent, the seller has to prove the higher amount was reasonable.1California Legislative Information. California Code CIV 1675 – Liquidated Damages in Residential Purchase Contracts That is why most agents set the deposit at or below three percent.
State-Mandated Seller Disclosures
California imposes some of the most extensive seller disclosure obligations in the country. These are not optional and cannot be waived by agreement between the parties.2California Legislative Information. California Code CIV 1102 – Disclosures Upon Transfer of Residential Property
Transfer Disclosure Statement
The Transfer Disclosure Statement (TDS) is the centerpiece. The seller fills it out to report known problems with the property, covering the roof, foundation, plumbing, electrical, appliances, and other structural or mechanical components. Both agents in the transaction add their own sections, noting anything they’ve observed on walkthroughs or learned through their involvement in the deal.3California Legislative Information. California Code CIV – Disclosures Upon Transfer of Residential Property
Timing matters. If the seller delivers the TDS after the buyer has already signed the purchase agreement, the buyer gets a statutory right to back out: three days after in-person delivery, or five days if it arrives by mail or electronic delivery.4California Legislative Information. California Code CIV 1102.3 – Rescission Period for Disclosures Short window, firm rule. It applies to any material amendment of a required disclosure, not just the original TDS.
Natural Hazard Disclosure
The Natural Hazard Disclosure (NHD) statement tells the buyer whether the property sits in any of six designated hazard zones: a FEMA special flood hazard area, a dam failure inundation area, a high or very high fire hazard severity zone, a wildland fire area, an Alquist-Priolo earthquake fault zone, or a seismic hazard zone for liquefaction or earthquake-induced landslides.
The seller or seller’s agent is responsible for delivering this disclosure, though in practice most agents order the report from a third-party NHD company that researches the property against official hazard maps. If the maps are not detailed enough to determine whether the property falls inside a zone, the seller must check “Yes” unless a professional report says otherwise.5California Legislative Information. California Code CIV 1103.2 – Natural Hazard Disclosure Statement
Safety and Compliance Certifications
California requires every residential water heater to be braced, anchored, or strapped against earthquake movement. At the point of sale, the seller must provide a written certification confirming this. The certification can appear on a standalone form or be folded into the TDS or the purchase contract itself.6California Legislative Information. California Health and Safety Code 19211 – Water Heater Bracing
Sellers must also confirm functioning smoke detectors and, in homes with fuel-burning appliances or an attached garage, carbon monoxide detectors. A separate written disclosure covers water-conserving plumbing fixtures: the seller must state whether the property contains any noncompliant fixtures, since California has required water-efficient plumbing in single-family homes since 2017.7California Legislative Information. California Code CIV 1102.155 – Water-Conserving Plumbing Fixtures Disclosure
Lead-Based Paint Disclosure
For any home built before 1978, federal law adds another required form. The seller must disclose all known information about lead-based paint in the property, hand the buyer the EPA pamphlet “Protect Your Family From Lead in Your Home,” and provide copies of any existing lead inspection reports. The buyer then gets a 10-day window to arrange a lead inspection or risk assessment before committing to the purchase, though the buyer can waive that period or the parties can agree to a different timeframe in writing.8U.S. Environmental Protection Agency. Real Estate Disclosures About Potential Lead Hazards
Both parties sign a lead warning statement confirming the steps were completed, and the seller must keep a signed copy for three years after closing. The rule does not apply to homes built after 1977, foreclosure sales, or housing exclusively for elderly or disabled residents where no child under six lives or is expected to live.8U.S. Environmental Protection Agency. Real Estate Disclosures About Potential Lead Hazards
Agency Relationship Disclosure
Before anyone starts negotiating, California law requires real estate agents to clarify who they represent. The Disclosure Regarding Real Estate Agency Relationship form, commonly called the AD form, explains the three possible roles an agent can fill: seller’s agent, buyer’s agent, or dual agent representing both sides.9California Legislative Information. California Code CIV 2079.13 – Agency Relationship Definitions It also spells out the fiduciary duties an agent owes to a client, and the baseline duty of honesty and fair dealing every agent owes to everyone in the transaction.
Each agent must confirm their specific role in writing, either in the purchase contract or in a separate document signed before or at contract execution.10California Legislative Information. California Code CIV 2079.17 – Agency Disclosure and Confirmation Dual agency triggers an additional layer of required consent from both parties, and the arrangement limits the agent’s ability to advocate on price or strategy for either side.
Federal Loan Disclosures
A buyer financing with a mortgage will see two federally mandated disclosures from the lender. These are not agent forms, but they control when closing can actually happen.
Loan Estimate
Within three business days of receiving a complete mortgage application, the lender must deliver a Loan Estimate. It breaks down the interest rate, monthly payment, estimated closing costs, and how those costs compare to what the borrower might pay over the life of the loan.11Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs
Closing Disclosure
The borrower must receive a Closing Disclosure at least three business days before loan consummation. It shows the final loan terms, monthly payment, and an itemized list of every closing cost. If the lender then makes a significant change, such as altering the annual percentage rate, changing the loan product, or adding a prepayment penalty, a new three-business-day waiting period starts over.11Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs Minor corrections can go through at or before consummation without resetting the clock. This three-day rule is one of the most common reasons closings get delayed, usually because a last-minute change triggers a fresh waiting period that nobody built into the schedule.
FIRPTA Forms When the Seller Is Foreign
When a foreign person or entity sells U.S. real property, federal law requires the buyer to withhold 15 percent of the sale price and remit it to the IRS.12Internal Revenue Service. FIRPTA Withholding Two forms come into play. If the seller is a U.S. person, they provide a Non-Foreign Affidavit (also called a FIRPTA certification) stating under penalty of perjury that they are not foreign, with their name, taxpayer ID, and home address. That affidavit eliminates the withholding requirement.
If the seller is foreign, the buyer is on the hook for withholding unless an exception applies. The most common one for residential deals: if the buyer intends to use the property as a personal residence and the price is $300,000 or less, no withholding is required. Above that threshold, the seller can apply to the IRS for a withholding certificate to reduce the amount, but that takes time and should be started early.13Internal Revenue Service. Exceptions from FIRPTA Withholding Escrow generally handles the mechanics, but the legal responsibility falls on the buyer.
The Deed and Preliminary Change of Ownership Report
The physical transfer of ownership happens through the deed, and most California residential sales use a grant deed. A valid deed must be in writing, identify the parties and the property, include operative words of conveyance, be signed by the seller, and be delivered to and accepted by the buyer. Recording is not technically required for the deed to be valid between the parties, but it establishes priority against later claims: the instrument recorded first wins.14California State Board of Equalization. Property Ownership and Deed Recording
Along with the deed, the buyer files a Preliminary Change of Ownership Report (PCOR) with the county recorder at the time of recording. This form notifies the county assessor of the transfer so the property can be reassessed for property tax purposes. Skipping it triggers an additional $20 recording fee, and the assessor will come looking for the information regardless.15California State Board of Equalization. Preliminary Change of Ownership Report
Where the Forms Come From
Most of the transactional documents, including the RPA, the AD form, and various addenda, live in the C.A.R. forms library. Access is generally restricted to licensed real estate professionals who are C.A.R. members, so buyers and sellers rely on their agents to generate, complete, and explain each form.
State-mandated disclosures like the TDS use a format prescribed by statute, and the NHD report is typically ordered from a third-party vendor. Federal forms like the Loan Estimate and Closing Disclosure come directly from the lender. The lead-based paint disclosure and FIRPTA affidavit are handled through escrow. The PCOR is a government form available from the county recorder or the California State Board of Equalization. Knowing which forms come from which source helps when something is missing or delayed, because the fix depends on whether you need your agent, your lender, or your escrow officer to act.
