Surrogacy Laws in Washington: A 2026 Guide

Overview

A same-sex couple from Texas, using donor eggs and their own sperm, matches with a surrogate in Spokane. Six months before their daughter is born, their attorney files a parentage petition. A Washington court grants a pre-birth order. Both fathers' names go on the original birth certificate — no post-birth adoption, no amendments, no additional court proceedings. The whole thing is routine. That is what a green-light state looks like in practice, and it is why Washington draws surrogacy journeys from across the country.

Washington enacted the Uniform Parentage Act (RCW 26.26A) in 2019, creating one of the most modern and explicit surrogacy frameworks in the country. Contracts are enforceable, pre-birth parentage orders are available statewide for all family structures, and the law applies regardless of marital status, sexual orientation, or whether donor gametes are involved.

For intended parents in restrictive states, Washington is one of the most common solutions. Your home state's laws do not govern what happens in Washington — the birth state controls parentage, and Washington's rules are about as clear as they get.

Surrogacy Contracts

Washington's Uniform Parentage Act (RCW 26.26A.700–26.26A.830) governs gestational surrogacy agreements. Under this statute, a valid surrogacy agreement must be in writing, executed before the embryo transfer, and signed by the intended parent(s), the surrogate, and the surrogate's spouse or partner if applicable.

Both parties must have independent legal representation before signing. The surrogate must have completed a prior pregnancy and given birth to at least one child. The agreement must be validated by a court before or after execution — Washington allows pre-approval, which adds certainty before any medical procedures begin.

Compensation for surrogates is expressly permitted beyond medical expenses. There is no statutory cap. This makes Washington contracts among the most commercially sophisticated and legally solid in the country.

Parentage and Birth Certificates

Washington law allows pre-birth parentage orders, meaning intended parents can obtain a court order before the baby is born naming them as the legal parents. The original birth certificate is then issued in the intended parents' names — no amendment, no adoption, no post-birth procedure required.

Pre-birth orders are available for all family structures: married heterosexual couples, same-sex couples, unmarried couples, and single intended parents. There is no requirement that either intended parent have a genetic connection to the child. Families using donor egg, donor sperm, or both are fully supported.

In practice, the parentage petition is typically filed during the second trimester. Most Washington courts process these routinely and the order is in hand well before delivery.

For Intended Parents

If your surrogate lives in or will deliver in Washington, you are in one of the best legal positions available in the country. Engage a Washington reproductive attorney early — ideally before your embryo transfer — to draft and validate your surrogacy agreement and file the parentage petition on the appropriate schedule.

Washington is a common destination for cross-state arrangements, which means there is a well-developed ecosystem of reproductive attorneys, clinics, and agencies experienced with multi-state journeys. If you live in a restrictive state and are working with a Washington surrogate, your own state of residence generally does not affect the Washington legal process.

Budget for legal fees separately from compensation and medical costs. A Washington reproductive attorney will typically quote a fixed fee for drafting the agreement and managing the parentage petition — ask for a written estimate before engaging, as it varies by firm and the specifics of your situation.

For Surrogates

Washington surrogates are among the most legally protected in the United States. Your agreement is enforceable, your compensation is unambiguously lawful, and the legal pathway for the intended parents is clear. Most major national agencies actively recruit and work with Washington surrogates.

You will need your own independent legal representation — not shared with the intended parents — before signing the surrogacy agreement. This is a statutory requirement, and reputable agencies and intended parents will cover the cost of your independent counsel as part of the standard arrangement.

Your surrogate compensation, allowances, and reimbursements should all be specified in the contract. Because Washington law is clear on enforceability, your contract provides real protection if any disputes arise.
