Sperm Donor Agreement: Does It Hold Up by State?
A sperm donor agreement carries real weight in some states and almost none in others. Parentage in the US is decided by state statute, and several states protect a donor from parental status only when a licensed physician performed the insemination. Where that condition exists, a signed agreement has repeatedly failed to change the outcome.
This article works through the statutes and the reported decisions that show how the rule actually applies, state by state, with the citation for each. One thing belongs at the top. sperm-donation.com is a matching platform. People create profiles, search, and message each other, and that is the entire product. We do not handle, store, test, or ship anything biological, we are not a clinic or a sperm bank, we do not verify identity or health, and we do not draft or review agreements or give legal advice. The checks, and the decisions, stay with you.
Does a sperm donor agreement hold up in court?
It depends on the state, and in a handful of states it has not held up at all. A written agreement is strong evidence of what two people intended. It cannot override a statute that makes a donor a legal parent whenever some other condition, such as physician involvement, was missing.
Two things are being decided at once whenever this comes up, and they are worth separating. The first is whether the donor is a legal parent, which controls custody, visitation and child support. The second is whether the intended second parent, if there is one, is recognized. Courts answer those questions using the state’s parentage statute. The agreement enters the picture as proof of intent, and its power depends entirely on whether the statute makes intent decisive.
What actually decides whether a donor is a legal parent
The state’s parentage statute decides it, and most of these statutes turn on one to three conditions: whether the donation went through a licensed physician or sperm bank, whether a written agreement exists and when it was signed, and whether the recipient was married.
That third condition is larger than most people expect. The Movement Advancement Project’s Parental Recognition Laws map, with data as of August 24, 2026, records that 20 states and the District of Columbia recognize an intended parent as a legal parent regardless of marital status if they consented to the conception, while 30 states and five territories recognize an intended parent only if they are married. MAP puts the population effect at 41 percent of LGBTQ adults living in the first group and 59 percent in the second. Many donor-parentage statutes were written in the 1970s and 1980s for married couples using a clinic, and the older wording still shapes results for everyone who does not fit that picture.
Which states require a physician for the donor rule to apply
Some states protect a donor from parental status only when a licensed physician was involved in the insemination. Kansas states the condition in the statute itself, and Virginia produces the same result through its definition of assisted conception. Both have been tested in reported decisions.
Kansas Statutes Annotated § 23-2208(f) provides that the donor of semen provided to a licensed physician for use in artificial insemination of a woman other than the donor’s wife is treated in law as if he were not the birth father, unless the donor and the woman agreed otherwise in writing. The physician clause sits in the sentence that grants the protection, so a donation arranged privately falls outside it.
Virginia reaches the same place by a different route. Code § 20-158(A)(3) says a donor is not the parent of a child conceived through assisted conception, and Code § 20-156 defines assisted conception as a pregnancy resulting from intervening medical technology. Whether a given arrangement counts therefore depends on what the court accepts as medical technology.
Whether any other state’s statute carries the same condition has to be checked in that state’s own code, because the wording varies and no reliable national list of physician-requirement states is published. A family law attorney licensed in the relevant state is the only dependable source on this point.
Kansas: what the Marotta case decided, and what it did not
The Kansas case involving William Marotta is the most cited example of a donor agreement failing, and its ending is frequently reported wrong. Marotta responded to a Craigslist advertisement, donated to a couple who inseminated at home without a physician, and signed documents waiving parental rights. He was still pursued for child support.
The Kansas Department for Children and Families petitioned in 2012 to have Marotta declared the legal father after the couple separated and the birth mother received state assistance. In January 2014, Shawnee County District Judge Mary Mattivi held that K.S.A. 23-2208(f) did not shield him, because no licensed physician had been involved, and that a parent may not terminate parental rights by contract even where the parties consented.
The case did not end there. On November 22, 2016, the same judge ruled that the birth mother’s former partner should be treated as the child’s second parent rather than Marotta, and that Marotta owed neither back payments to the state nor future child support. The reporting at the time noted his minimal contact with the child as part of the reasoning. Two lessons come out of that sequence. A signed agreement did not stop four years of litigation, and the eventual protection came from a second-parent finding rather than from the document.
Virginia: why a turkey baster changed the outcome
In Bruce v. Boardwine, decided April 21, 2015, the Court of Appeals of Virginia held that a home insemination performed with a turkey baster did not qualify as assisted conception, so the donor was never a donor in the statutory sense and could seek custody as the biological father.
The facts are ordinary. Joyce Bruce asked a longtime friend, Robert Boardwine, to donate. They discussed a written contract and never signed one. Boardwine brought a container of sperm to her home, and Bruce inseminated herself with a turkey baster. When the relationship between them broke down after the birth, Boardwine petitioned for paternity and custody. DNA testing established his paternity at a probability greater than 99.999 percent.
The court read the statute literally. The plain meaning of the term medical technology, it wrote, does not encompass a kitchen implement such as a turkey baster, and the other procedures listed in Code § 20-156 all involve medical personnel. Boardwine received joint legal and physical custody along with visitation. The case is a clean illustration of how the method of insemination, which feels like a practical detail, can decide the legal question. If you are weighing that choice, the mechanics themselves are covered in our guide to how home insemination works.
California: the state that wrote the home route into the statute
California is the clearest example of a statute that gives a written agreement decisive force outside a clinic. Family Code § 7613, current as of January 1, 2026, sets out two separate paths, one for clinic donations and one for everything else.
Under § 7613(b)(1), a donor who provides semen to a licensed physician and surgeon or a licensed sperm bank is treated as not the natural parent, unless the donor and the woman signed a written agreement before conception that he would be a parent. Under § 7613(b)(2), where the semen was not provided to a physician or sperm bank, the donor is still treated as not the natural parent if either the donor and the woman signed a written agreement before conception that he would not be a parent, or a court finds by clear and convincing evidence that they had an oral agreement to that effect before conception.
The word before is doing heavy lifting in both subsections. An agreement signed after conception does not meet the statutory description, which is the single most common way this provision is misread. California’s own history explains why the second path was added: in Jhordan C. v. Mary K. (1986), a donor who handed over sperm directly, with no physician, was found to be the child’s legal father under the version of the statute then in force.
Pennsylvania: when a court enforced an agreement with no writing at all
Pennsylvania has no donor parentage statute of the California kind, and its Supreme Court instead enforced an oral agreement. Ferguson v. McKiernan, 940 A.2d 1236, decided December 27, 2007, released a known donor from child support for twins on the strength of an unwritten understanding.
The court’s reasoning was contract-based. The agreement had been negotiated outside a romantic relationship, the donor had relied on the mother’s promise to release him from parental responsibility, and that release formed part of the bargained-for exchange. The decision reversed both the Court of Common Pleas and the Superior Court, and it came down 3 to 2 with two dissents, which is a fair signal of how contested the ground is.
Read alongside Kansas, Ferguson shows the whole spread. The same document, or in that case no document at all, produced opposite results in two states because the statutes and the doctrines behind them differ.
New York: the Child-Parent Security Act and donative intent
New York’s Child-Parent Security Act took effect on February 15, 2021 and states the rule directly. Family Court Act § 581-302 provides that a donor is not a parent of a child conceived by assisted reproduction or artificial insemination, except as provided in § 581-303.
The practical catch sits in the known-donor scenario. Where the donor is known to the recipient, the court requires proof of the donor’s intent not to be a parent before it will grant a judgment of parentage to the intended parents. A written agreement predating the conception is the usual way that intent gets proved, which puts New York in the group of states where documentation carries real evidentiary weight without being the whole of the test.
States that follow the 2017 Uniform Parentage Act
The 2017 Uniform Parentage Act removes the physician condition entirely. Its donor provision states that a donor is not a parent of a child conceived by assisted reproduction, and its definition of assisted reproduction does not require a clinic, which is why home insemination is covered.
Enactment has been gradual. A report published by the American Academy of Matrimonial Lawyers records nine states as having enacted the UPA 2017: California, Colorado, Connecticut, Maine, Massachusetts, Oregon, Rhode Island, Vermont and Washington, with Massachusetts effective January 1, 2025. Michigan enacted the assisted reproduction provisions in 2024 without adopting the full act. Because the list moves with each legislative session, the enactment status of any particular state has to be checked against that state’s current code rather than against an article.
The 2017 act also does more than protect the donor. It recognizes an intended parent who consented to the conception regardless of marital status, which is the provision behind most of the 20 states plus DC in the MAP count above.
A compact state-by-state read
The list below groups the states discussed in this article by what their law turns on. It covers only the states with statutes or decisions cited here, so treat it as a way to recognize which pattern your own state might follow rather than as a national survey.
Kansas. The outcome turns on licensed physician involvement, per K.S.A. 23-2208(f). A written agreement did not substitute for it in the Marotta litigation.
Virginia. The outcome turns on whether intervening medical technology was used, per Code § 20-156. A turkey baster did not qualify in Bruce v. Boardwine (2015).
California. The outcome turns on a written agreement signed before conception, or on a proven oral agreement made before conception, per Family Code § 7613(b)(2).
Pennsylvania. The outcome turned on contract principles when the question reached the state Supreme Court. An oral donor agreement was enforced in Ferguson v. McKiernan (2007).
New York. The outcome turns on donative intent, per Family Court Act § 581-302, with proof required where the donor is known to the recipient.
States that enacted the 2017 Uniform Parentage Act. The outcome turns on donor status alone, with no physician condition, in the nine states the American Academy of Matrimonial Lawyers report lists as having enacted the act.
What a donor agreement can and cannot do
An agreement records what everyone intended at the time, and in several states that record is the thing a court needs. In other states it changes nothing about parentage, and its value is limited to setting expectations between the adults.
The parts that people commonly write down are the donor’s role in the child’s life, whether and how the child will be told, contact between the donor and the family, future donations to siblings, and who pays for what. Those points reduce the chance of the disagreement that gets people into court in the first place. They also become the factual record if a court later has to reconstruct intent, as it did in California’s oral-agreement provision and in the New York donative-intent requirement.
What an agreement cannot do is waive the child’s right to support. That is the principle Judge Mattivi stated in Kansas in 2014, and it appears in some form in most states. The obligation belongs to the child, so two adults cannot contract it away between themselves. Where a donor escapes support, it is because the statute says he was never a parent, rather than because he signed something.
Anyone drafting one is choosing a legal document, and that is work for a family law attorney in the relevant state. Our role stops well before that point. We connect people who are looking for each other, and everything after the introduction is theirs to arrange.
How this interacts with choosing a bank instead
Buying from a cryobank moves the parentage question into the safest configuration in almost every state, because the bank donor is anonymous or identity-release, the donation passes through a licensed establishment, and the physician condition is satisfied wherever it exists. The tradeoff is cost and the loss of a known person in the child’s life, which we set out in donor sperm costs and in the bank versus known donor comparison.
Known donation puts the legal question back in your hands and gives the child a person to know. That is the tradeoff people are actually weighing, and it is worth being honest that the legal exposure is the price of the second option in a fair number of states. The practical side of finding someone is covered in finding a known sperm donor, and the safety questions in is a free sperm donor safe.
One pattern deserves a plain mention because it comes up in private arrangements. Some people offering to donate propose intercourse instead of insemination, described in donor communities as natural insemination. It is a reported pattern and a risk rather than a method. It removes the assisted-reproduction framing that every donor statute discussed here depends on, and it carries the health and safety exposure of sex with a stranger.
Frequently asked questions
Is a sperm donor agreement legally binding in the US?
There is no single national answer, because parentage is state law. In California, Family Code § 7613(b)(2) makes a written agreement signed before conception decisive for a donation that did not go through a physician or sperm bank. In Kansas, K.S.A. 23-2208(f) grants the donor protection only where a licensed physician was involved, and a signed waiver did not prevent the state from pursuing William Marotta for child support in litigation that ran from 2012 to 2016.
Can a sperm donor be ordered to pay child support?
Yes, in states where he is treated as a legal parent. That happens when the state's donor statute does not apply to the arrangement, for example because no licensed physician was involved in a state that requires one. In Bruce v. Boardwine (Va. Ct. App. 2015) the donor was held to be the father after a home insemination and received joint custody. Support obligations belong to the child, so adults cannot waive them by agreement.
Does the agreement have to be signed before conception?
In California it does. Family Code § 7613(b)(2)(A) refers to a written agreement signed before conception, and § 7613(b)(2)(B) to an oral agreement made before conception, proved by clear and convincing evidence. Other states word the timing differently or do not address it, so the requirement has to be read out of the specific state's statute.
Which states are safest for a known donor arrangement?
States that have enacted the 2017 Uniform Parentage Act give the clearest protection, because the act's donor provision has no physician condition and its assisted reproduction definition covers home insemination. An American Academy of Matrimonial Lawyers report lists California, Colorado, Connecticut, Maine, Massachusetts, Oregon, Rhode Island, Vermont and Washington as having enacted it. Enactment changes with each legislative session, so the current code of the state in question is the only reliable check.
Does the donor have to go through a clinic for the agreement to work?
It depends on the state. Kansas and Virginia both produce donor protection that depends on medical involvement, through K.S.A. 23-2208(f) and through the definition of assisted conception in Virginia Code § 20-156. California expressly provides for donations that did not go through a physician or sperm bank in Family Code § 7613(b)(2). The 2017 Uniform Parentage Act sets no such condition at all.
Does an agreement protect the non-biological second parent?
Only indirectly. Second-parent recognition is a separate question with its own rules. The Movement Advancement Project records, with data as of August 24, 2026, that 20 states and DC recognize an intended parent regardless of marital status where they consented to the conception, while 30 states and five territories recognize one only if married. In the remaining states the usual route is a court order or an adoption, which a family law attorney in that state can explain.
What happens if the donor and the recipient live in different states?
The law that applies is usually that of the state where the child lives and where any proceeding is brought, which may be neither the state where the agreement was signed nor the state where the donor lives. That mismatch is one of the reasons attorneys advise having the agreement reviewed in the state where the child will be born. This is a jurisdictional question with real consequences, and it needs an attorney rather than a template.
The short version
In most of the country the state statute decides this and the document plays a supporting role. The two conditions the statutes most often turn on are physician involvement and the timing of any written agreement. Where a state has enacted the 2017 Uniform Parentage Act, a known donor who did not intend to parent is protected without a clinic. Where a state still conditions the protection on medical involvement, as Kansas does in its text and Virginia does through its definitions, a private arrangement leaves the donor exposed and leaves the recipient with a person who has standing to seek custody.
Anyone in this position benefits from two conversations before conception rather than after: one with the other party about roles and expectations, and one with a family law attorney licensed in the state where the child will live. Everything else in this article is background for those two conversations.
