What Is Assisted Reproduction Law in Washington?

Families are built in more ways than ever, and Washington law has caught up. Assisted reproduction law is the set of rules that decides who a child's legal parents are when conception happens with medical help rather than through intercourse. This topic is part of Washington adoption and assisted reproduction law.

A Modern Framework for Modern Families

Assisted reproduction law in Washington lives in the Uniform Parentage Act at RCW 26.26A.600 through 26.26A.635. Washington adopted this framework as part of a broader modernization of its parentage law, effective in 2019, in order to give clear answers to questions that older law handled poorly or not at all. The goal is certainty. When a child is conceived through medical assistance, the law aims to make it clear from the outset who the parents are, so that families are not left to litigate parentage after the fact.

The statute starts by defining what it covers. Under RCW 26.26A.010, assisted reproduction means a method of causing pregnancy other than sexual intercourse. That definition expressly includes intrauterine or intracervical insemination, the donation of gametes, the donation of embryos, in-vitro fertilization and the transfer of embryos, and intracytoplasmic sperm injection. In plain terms, if a pregnancy is achieved with medical help rather than through intercourse, this body of law is likely in play.

What This Law Does and Does Not Cover

It is worth understanding the boundaries. RCW 26.26A.600 makes clear that the assisted reproduction rules do not apply to a child conceived through sexual intercourse, and they do not apply to a child conceived through a surrogacy agreement, which Washington governs separately under RCW 26.26A.700 through 26.26A.785. So there are really two neighboring frameworks. One set of rules covers assisted reproduction where the woman giving birth is the intended parent, and a separate set covers surrogacy, where the woman carrying the pregnancy is not an intended parent. Knowing which framework applies to your situation is the first step, because the rules and required documents differ.

The Central Rule of Parentage

The core of assisted reproduction law is a single, powerful idea: parentage follows consent and intent. RCW 26.26A.610 provides that an individual who consents to assisted reproduction by a woman, with the intent to be a parent of the resulting child, is a parent of that child. This rule frees parentage from being tied strictly to genetics or to giving birth. A parent who uses donor sperm, a donor egg, or a donor embryo can be the child's legal parent because they intended to be and consented to the process. For many families, that is exactly the recognition they are seeking.

Washington then explains how that consent should be shown. RCW 26.26A.615 provides that the consent must ordinarily be in a written record signed by the woman giving birth and by the person who intends to be a parent. This is the gold standard, and it is the surest way to lock in parental status. The same section also supplies fallback routes to establish consent when the written record is missing, such as proof by clear and convincing evidence of an express pre-conception agreement to both be parents, or proof that the parties lived together with the child and openly held the child out as their own during the child's first four years, with special rules where death or incapacity intervenes. These backstops are valuable, but they require going to court and meeting a demanding standard of proof, which is why a signed consent up front is always preferable.

The Role and Protection of Donors

Donors are essential to assisted reproduction, and the law treats their role with clarity. RCW 26.26A.605 states simply that a donor is not a parent of a child conceived by assisted reproduction. The definitions in RCW 26.26A.010 reinforce this by defining a donor as an individual who provides gametes for use in assisted reproduction, whether or not for payment, while excluding from that definition both the intended parents and, in the assisted reproduction context, the woman who gives birth. The practical effect is important in both directions. A donor cannot be forced into the legal and financial responsibilities of parenthood, and a donor cannot assert parental rights over a child conceived from their donation. That protection gives intended parents confidence and gives donors clarity about their role.

Why This Area of Law Matters

The value of assisted reproduction law is that it replaces uncertainty with rules. Without it, a family that used a donor might face questions years later about whether the donor could claim the child, or whether a non-genetic parent was truly a parent in the eyes of the law. By grounding parentage in consent and intent, and by declaring that donors are not parents, Washington gives families a stable legal foundation. That stability is not just about peace of mind. It touches inheritance, medical decision-making, custody, child support, and every other area where legal parenthood matters.

Because the rules reward careful documentation, the smartest time to think about them is at the very beginning of the process, not after a child is born. Making sure consent is in a signed record, keeping clear documentation of everyone's roles and intentions, and confirming which framework applies to your situation are all steps that prevent problems before they start.
