Washington Purchase Contracts & Seller Disclosures

Washington does not offer a free state-agency purchase agreement for an ordinary home resale. Brokers commonly use privately licensed NWMLS Statewide Forms—often Form 21. Choose your situation:

Working with an agent or broker

Ask your brokerage for its current authorized purchase agreement, addenda, and seller-disclosure form—often an NWMLS Statewide Forms package.

See the agent and broker path

Buying or selling without an agent (FSBO)

Have a Washington real-estate lawyer prepare or review the agreement before either side signs, and complete the statutory seller disclosure when it applies.

Washington seller disclosure: two important clocks

For most covered improved-home sales, the seller must deliver a completed seller disclosure no later than five business days after mutual acceptance, unless the parties agree otherwise. The buyer generally has three business days after receipt to rescind in the buyer’s sole discretion. Exemptions, a valid waiver, or different agreed timing can change these rules, and required environmental disclosure cannot always be waived.

Read Washington disclosure rules

PublicLegal does not sell or reproduce NWMLS Statewide Forms, and we do not pass off a generic national contract as Washington-specific.

Washington law and forms checked August 2026 · Sources include RCW 64.06 (updated June 11, 2026; further change January 1, 2027) and Washington DOL

PublicLegal provides independent self-help guidance and links to Washington primary sources. We do not sell or reproduce NWMLS purchase contracts or NWMLS-branded disclosure forms.

Do not assume you can cancel for any reason after signing. The Chapter 64.06 seller-disclosure rescission right has short written-notice deadlines. Inspection, financing, appraisal, title, association-document, and lead rights have separate rules.

Editorial summary based on Chapter 64.06 RCW (seller disclosures), RCW 64.04 conveyancing practice, Washington DOL real-estate licensing materials, EPA lead-disclosure materials, and common NWMLS Statewide Forms market practice. Re-check the current RCW text and the exact brokerage-authorized form versions before you rely on deadlines. RCW 64.06.020 already reflects a June 11, 2026 amendment and changes again January 1, 2027.

Who this page is for

  • Buyers or sellers trying to understand how Washington residential purchase contracts usually work
  • People working with a Washington agent who want plain-English context before signing brokerage forms
  • FSBO parties who need a safe written-contract path and the correct disclosure checklist
  • Buyers tracking Form 17 / RCW 64.06 delivery and three-business-day rescission clocks

Who should use another path

  • Anyone looking to download a PublicLegal “official NWMLS Form 21” — we do not sell that
  • Users who need a filled-in offer for a live transaction without professional help on complex terms
  • Commercial, heavily customized, development, or entity deals that need specialized Washington counsel from the start

The purchase agreement creates the parties’ contractual obligations. The seller disclosure statement is a separate statutory document. The deed transfers title later at closing. Do not treat a deed form as a substitute for the purchase contract.

Washington does not issue one free government residential purchase blank for ordinary resales. Licensed practice often uses NWMLS Statewide Forms or another appropriate current agreement supplied through the professionals on the deal. Those forms are a private industry standard—not a claim that every sale is legally required to use Form 21.

Washington residential transactions commonly close through a title or escrow company. Limited Practice Officers may prepare approved closing documents under court rules, but they do not replace party-specific legal advice.

Two common Washington situations

Working with an agent or broker

If a Washington real-estate licensee is handling your transaction, that professional typically selects and supplies the current purchase agreement and addenda authorized by the brokerage. In many Washington markets the package uses NWMLS Statewide Forms—commonly Form 21 for the residential purchase and sale agreement, with separate financing, inspection, and other addenda. These are privately copyrighted industry forms—not a DOL consumer blank and not a free PublicLegal download.

PublicLegal does not host, sell, or reproduce NWMLS Statewide Forms. Do not rely on random internet copies; they may be unauthorized, altered, or outdated. Ask which form and revision is being used and read financing, inspection, earnest money, title, appraisal, disclosure, possession, and default provisions carefully before signing.

Your brokerage should also supply a current compliant seller disclosure statement (often called Form 17 in the market). The legal duty comes from Chapter 64.06 RCW, not from the form number alone. Calendar every contract and disclosure deadline from the actual signed documents.

Buying or selling without an agent (FSBO)

Washington does not publish a free state-agency residential purchase-contract blank for ordinary FSBO resales. Unrepresented parties still need a signed written agreement covering price, earnest money, financing, inspections, title, closing, possession, defaults, and related logistics, with a reliable property description.

The safer contract path is a Washington real-estate attorney who prepares or reviews the agreement before anyone signs. An escrow company or Limited Practice Officer can help with closing documents after the parties have agreed in writing to basic terms, but cannot act as your personal contract lawyer or give party-specific legal advice.

FSBO sellers remain subject to Chapter 64.06 seller-disclosure duties when the transfer is covered, unless an exemption applies or the buyer validly waives receipt (with statutory limits on environmental-section waiver). Federal lead rules still apply to most pre-1978 housing.

PublicLegal does not sell a Washington purchase-contract substitute on this page. For lawyer-directory starting points, see the Washington State Bar Association’s Find Legal Help resources.

Washington seller disclosures: RCW 64.06, Form 17, and related notices

For most covered improved residential sales, Chapter 64.06 RCW requires the seller to deliver a completed seller disclosure statement in the statutory format unless the buyer has expressly waived the right to receive it or the transfer is exempt. Brokers commonly call the residential statement “Form 17.” The legal duty is the statute’s seller disclosure statement—not a DOL-issued form number that PublicLegal can sell.

Unless the parties agree otherwise, delivery must occur not later than five business days after mutual acceptance of a written purchase contract. Within three business days after receipt (or as otherwise agreed), the buyer may approve and accept the statement or rescind the purchase agreement by delivering a separately signed written statement of rescission to the seller or seller’s agent. If the buyer does not timely rescind, the disclosure is generally deemed accepted. The statement is based on the seller’s actual knowledge, is for disclosure only, is not a warranty, and is not part of the purchase contract.

If the seller fails or refuses to provide the statement, the buyer’s rescission right generally continues until the earlier of three business days after the statement is finally received or the date the transfer closes, unless the buyer has waived rescission in writing. If, after delivery, the seller learns of additional information or an adverse change that makes any disclosure inaccurate, the seller must amend and deliver the amendment, subject to a corrective-action exception when accuracy is restored at least three business days before closing. An amendment can restart a three-business-day rescission window.

Buyers may expressly waive receipt of the disclosure statement under RCW 64.06.010, but the statute limits waiver of the Environmental section when any answer there would be “yes.” Confirm the current exemption list and waiver rules in the statute for your facts. Separate statutory formats exist for unimproved residential and commercial property.

RCW 64.06.020 already reflects a June 11, 2026 amendment and is scheduled to change again on January 1, 2027. Use a current form. Most housing built before 1978 also triggers federal lead-based paint disclosures and the EPA pamphlet before contract. Condominium and common-interest community resales can require separate association resale certificates or public offering statements under Washington common-interest statutes—those packets are not the same document as the Chapter 64.06 seller disclosure and can create separate cancellation rights depending on the community type and governing statute.

Common exemption categories

Key points to keep straight:

  • Default delivery is within five business days after mutual acceptance unless otherwise agreed
  • Default buyer rescission window is three business days after receipt of the disclosure statement
  • Rescission requires timely written notice—do not assume a free-floating cooling-off period for every reason
  • “Form 17” is a common market name for the statutory residential disclosure statement
  • Environmental-section answers that would be “yes” cannot always be waived
  • Condo/HOA resale certificates are a separate track from Chapter 64.06
  • The improved-residential form text changes again January 1, 2027

When in doubt about what must be disclosed for your facts, ask Washington counsel. Complete the current forms required by statute and your contract.

Washington purchase checklist

Use this as a practical sequence—not a substitute for advice on your facts.

  1. Confirm whether a Washington real-estate licensee is supplying the purchase agreement
  2. If yes, obtain the current authorized NWMLS or other brokerage forms and addenda—do not rely on random internet blanks labeled “Form 21”
  3. If no, arrange Washington real-estate attorney preparation or review before anyone signs
  4. Deliver the Chapter 64.06 seller disclosure within the default five-business-day window after mutual acceptance when required
  5. Buyers: calendar the three-business-day post-receipt rescission window and any contractual contingencies
  6. Address federal lead materials for most pre-1978 housing
  7. Request condo/HOA resale documents early when the property is in an association
  8. Select title/escrow professionals and confirm deposit, signing, and recording logistics
  9. Treat the deed as part of closing—not a DIY substitute for the purchase contract
  10. If required disclosures are missing or a rescission clock may be running, get Washington legal advice promptly

Step summary

  1. Identify who supplies the agreement An agent-assisted deal usually uses the brokerage’s current authorized forms. An FSBO deal usually needs attorney-prepared or attorney-reviewed writing before signature.
  2. Handle seller disclosure on the statutory clocks Track five-business-day delivery after mutual acceptance and three-business-day buyer rescission after receipt unless a valid waiver, exemption, or different agreed timing applies.
  3. Investigate during contractual contingency windows Disclosures are not a warranty. Preserve inspection, title, financing, and association-document rights in the signed agreement.
  4. Close with verified instructions Coordinate deed, funding, taxes, and recording with your escrow/title professionals. Verify wires independently.

Inspections, contingencies, and other deal issues

Depending on the property and transaction, parties may also need to address:

  • Contractual inspection, financing, appraisal, title, and closing deadlines in the signed agreement
  • Home, sewer, septic, pest, environmental, and other inspections appropriate to the property
  • Federal lead materials for most pre-1978 housing
  • Condominium or common-interest community resale certificates / public offering statements
  • Local city or county transfer, inspection, or occupancy requirements
  • Wire-fraud precautions—verify closing instructions by phone using a known number

Local practices differ across Washington markets. Use professionals and primary sources for your address—not a generic national packet.

Washington title, escrow, LPOs, and attorneys

Washington residential purchases commonly close through a title or escrow company that holds funds, issues the title commitment, coordinates lender and signing requirements, and completes recording. That provider is not automatically your personal lawyer for negotiating contract rights or disclosure disputes.

Washington court rules allow Limited Practice Officers to prepare certain approved closing documents. An LPO generally acts after the parties have agreed in writing to basic transaction terms and cannot give legal advice to either party. An LPO or escrow officer is not a substitute for a Washington real-estate attorney on FSBO contract drafting or disputed terms.

A Washington real-estate attorney can prepare or review the purchase agreement, advise on title objections, association documents, estate or entity authority, boundary issues, and custom terms. Consider counsel early in FSBO deals and whenever deadlines or documents are unclear.

The purchase agreement creates the sale obligations. The deed conveys title at closing. PublicLegal’s deed resources can help when you need conveyance forms, but a deed is not a substitute for the purchase agreement. A Washington-specific deed router page is not live yet; use the general deed hub and coordinate with counsel or title professionals.

Independently verify wire instructions. Real-estate wire fraud is common.

When to talk with a Washington real estate attorney

  • No agent is involved and you need a purchase agreement prepared or reviewed
  • You do not understand form deadlines, contingencies, or earnest-money terms
  • Seller financing, assignment/wholesale, trust, estate, entity, or boundary issues appear
  • The property is a condo or common-interest community with complex association documents
  • A disclosure statement arrived late, is incomplete, or a party is considering rescission under Chapter 64.06
  • Custom occupancy, repair, or possession terms are requested

What PublicLegal does not sell for Washington

  • NWMLS Form 21, NWMLS Statewide Forms addenda, or any lookalike or derivative
  • An “official Washington” or “DOL-approved” residential purchase agreement
  • An NWMLS-branded Form 17 sold as a PublicLegal blank
  • A generic national purchase blank or national disclosure form relabeled as Washington-required
  • A deed or closing packet represented as a substitute for the purchase agreement or for Washington counsel

That keeps this page honest: orientation and primary-source links, not a substitute for authorized industry forms or Washington legal advice.

Frequently asked questions

Is there an official Washington government home purchase contract?

Washington does not provide a free state-agency purchase agreement for ordinary home resales. Many brokered deals use NWMLS Statewide Forms—often Form 21—or another brokerage-authorized package. PublicLegal does not sell an NWMLS lookalike.

Is NWMLS Form 21 required by Washington law?

No statute makes Form 21 mandatory for every residential sale. NWMLS Statewide Forms are a widely used private industry standard. Your brokerage’s current authorized forms control for an agent-assisted deal.

What is Form 17?

Form 17 is the common market name for a residential seller disclosure statement that follows Chapter 64.06 RCW. The legal duty is the statutory seller disclosure statement. It is separate from the purchase agreement.

When must the seller deliver the disclosure statement?

Unless waived or exempt, and unless the parties agree otherwise, delivery is due not later than five business days after mutual acceptance of a written purchase contract.

How long does a buyer have to rescind after receiving the disclosure?

Unless otherwise agreed, the buyer generally has three business days after receipt to rescind in the buyer’s sole discretion by delivering a separately signed written rescission notice. Missing that window usually means the disclosure is deemed accepted.

Do Washington buyers have a general cooling-off period after signing?

No. There is no free-floating “cancel for any reason” period for every home purchase. Chapter 64.06 creates a short disclosure-based rescission path. Other cancel rights come from the signed contract or separate laws such as lead or association-document rules.

Is a deed the same as a purchase contract?

No. The purchase agreement is the contract to buy and sell. Title typically transfers later by deed at closing. A deed form is not a substitute for the purchase agreement.

Should an FSBO buyer or seller use a Washington attorney?

Yes—having a Washington real-estate attorney prepare or review the written agreement before signature is the safer unrepresented path. Escrow companies and Limited Practice Officers do not replace that advice. This page is orientation, not representation.

What is different for a condo or HOA home?

Besides the Chapter 64.06 seller disclosure when applicable, condominium and common-interest community resales often require a separate resale certificate or public offering statement from the association. Those documents can create separate cancellation rights depending on the community type and governing statute. Request them early and review with professionals.

PublicLegal provides self-help forms and information. This is not legal advice. Real estate purchase and disclosure rules vary by state and transaction. Confirm requirements for your property with a qualified professional when needed.
