Known Donor in California: Law, Cost, and Clinics

2026-08-28 · M. Ewert

A known sperm donor in California is treated in law as not the natural parent of the child in two situations: the sperm was provided to a licensed physician and surgeon or to a licensed sperm bank before insemination, or the donor and the woman signed a written agreement before conception saying he would not be a parent. Family Code Section 7613(b) sets out both routes.

California is unusual in giving people a second route that works outside a clinic, and unusual again in publishing free statutory forms that satisfy the writing requirement. This article covers what Section 7613(b) requires, what the statutory forms do and do not do, how a California court has treated a donor who later acted as a father, what the licensed route costs in 2026, and what changed for insurance on January 1, 2026. One thing belongs at the top. sperm-donation.com is a matching platform, 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 give legal or medical advice. The checks, and the decisions, stay with you.

Is a known sperm donor legal in California?

Yes. California places no restriction on who may donate sperm privately, and no restriction on inseminating at home. The law regulates two other things: the parentage that results, and any business that collects, processes, stores, or distributes sperm.

The parentage rules sit in the California Uniform Parentage Act, Family Code Sections 7600 and following. The business rules sit in the Health and Safety Code, which requires a state tissue bank license for any gamete bank operating in California. Two people arranging a donation between themselves fall outside the licensing regime entirely, which is why the parentage question is the one that matters for a private arrangement.

Does a sperm donor have parental rights in California?

A donor who meets one of the conditions in Section 7613(b) is treated in law as if he is not the natural parent, which removes both his claim to custody and any claim against him for child support. A donor who meets none of them is in an open question that a court decides.

Family Code Section 7613(b) is written in two paragraphs, and they cover different situations. Paragraph (b)(1) applies where the semen was provided to a licensed physician and surgeon or to a licensed sperm bank for use in assisted reproduction by a woman other than the donor’s spouse. In that case the donor is not the natural parent unless he and the woman signed a written agreement before conception saying that he would be a parent.

Paragraph (b)(2) applies where the semen was not provided to a licensed physician or licensed sperm bank. The donor is still treated as not the natural parent if either of two things is true: 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 the child was conceived through assisted reproduction and that the woman and the donor had an oral agreement before conception that he would not be a parent.

The practical reading is that California gives a private arrangement a clean paper route and a messy fallback: a written agreement signed before conception, or a judge weighing evidence about a conversation under the clear and convincing standard years later.

What counts as assisted reproduction in California?

Section 7613(b)(2) only helps where the child was conceived through assisted reproduction, which means conception by a method other than sexual intercourse. Conception through sex falls outside the section, and the donor exemption does not apply to it at all.

This is the single most consequential line in California’s framework for people arranging privately. Where users offering so-called natural insemination come up on donor sites and in groups, that is a pattern people report rather than a method presented alongside others, and in California it carries a specific legal consequence on top of the health risk: the statute that removes a donor’s parentage does not reach a child conceived through intercourse. Our guide on whether a free sperm donor is safe goes through the risk picture in more detail, and what people test for before a donation covers the health side.

Do the California statutory forms replace a lawyer?

No. They satisfy the writing requirement in Section 7613, and they are free, but they do not settle every parentage question and the statute itself says so.

Family Code Section 7613.5 publishes four optional California Statutory Forms for Assisted Reproduction. Form 4 is the one written for known donation, headed “Intended Parent(s) Using a Known Sperm and/or Egg Donor(s) to Conceive a Child”. It is used where the intended parents do not intend for the donor to be a parent, and it is signed by the person giving birth, by the donor, and by a second intended parent where there is one, with a notary acknowledgment.

The text of the section is careful about its own limits. The forms “do not affect any presumptions of parentage based on Section 7611, and do not preclude a court from considering any other claims to parentage under California statute or case law”. The forms also do not apply to surrogacy or gestational carrier agreements, and every form carries the line that the laws about parentage are complicated and that readers are strongly encouraged to consult an attorney about their rights.

Form 1 carries a warning worth quoting for anyone using a known donor while partnered: signing the form that establishes a second intended parent “does not terminate the parentage claim of a sperm donor”. Those are two separate pieces of paper doing two separate jobs. A comparison of how other states handle the same document is in our overview of donor agreements state by state.

Can a California donor become a legal parent later?

Yes, on a different legal theory, and this is the part of California law most often missed. Section 7613(b) blocks a claim to parentage based on the biological connection. It does not block a claim based on how the donor behaved after the child was born.

The case is Jason P. v. Danielle S., which reached the California Court of Appeal twice. In the first appeal, decided in 2014, the court held that Section 7613(b) precludes a sperm donor from establishing paternity based on his biological connection to the child, and does not preclude him from establishing that he is a presumed parent under Section 7611(d) based on post-birth conduct. In the second appeal, decided in 2017, the court held that the family law court had properly applied the law of presumed parentage in finding Jason to be a presumed father and that the finding was supported by substantial evidence, while conditionally reversing the joint custody award on a separate point.

Section 7611(d) makes a person a presumed parent where they received the child into their home and openly held the child out as their own. That is a description of conduct rather than of paperwork, so it can be built up over months of ordinary involvement without anyone intending a legal result. Families who want a donor in the child’s life as a known figure and not as a parent are describing the situation the case turned on, which is why the arrangement is worth talking through before conception rather than assuming a signed form covers it. Our guide to a first meeting with a known donor covers that conversation, including contact after birth.

Does home insemination change anything in California?

It changes which paragraph of Section 7613(b) applies. Insemination at home without a physician means paragraph (b)(2) governs, so the written pre-conception agreement carries the weight that a clinic’s records would otherwise carry.

Nothing in California law requires a doctor for insemination, and nothing makes home insemination unlawful. What disappears without a licensed physician or licensed sperm bank in the chain is the automatic operation of paragraph (b)(1), along with the clinic’s dated records, its screening file, and its independent evidence that a donation happened on a particular day. The method itself is the same everywhere, and how home insemination works explains it without the legal layer. Some people in California use a licensed sperm bank purely to put the arrangement inside paragraph (b)(1), storing a known donor’s samples rather than buying from a catalog, and the section below sets out what that costs.

What does California require of sperm banks and clinics?

California requires a state tissue bank license for any facility that collects, processes, stores, or distributes sperm, on top of federal FDA registration. The requirement sits in Health and Safety Code Sections 1635 and following, and licensing is handled by the Tissue Bank Section of the California Department of Public Health, which licenses and surveys assisted reproductive technology facilities including sperm banks.

Two consequences follow. An out-of-state cryobank has to hold a California license to supply sperm into the state, so licensing status is worth checking before selecting a donor. A private arrangement between two people is outside the regime, which means no license, no inspection, and no file: the screening and the record keeping are whatever the two people decide to do.

Health and Safety Code Section 1644.5 adds a layer about infectious disease. It sets out when sperm from a donor who has tested reactive for hepatitis B, hepatitis C, syphilis, HIV, or HTLV may be used, and it requires the physician providing the service to advise both donor and recipient of the medical risks, with both signing a document confirming that they consent. That framework applies to the clinic route and says nothing about what two people do privately, which is the point most often missed by people who assume the state is checking something.

How much does a known donor route cost in California in 2026?

The published figures come from banks rather than from any state schedule, and they vary widely. The Sperm Bank of California, a licensed nonprofit bank in Berkeley, publishes a fee page that puts real numbers on the known donor route.

On its fee schedule as published in July 2026, a Known Donor account has an initial appointment cost of $3,350, made up of $1,300 for account setup and consultation including the donor eligibility determination under FDA, California, and New York rules, $550 for lab processing of the first sample, $600 for the first year of annual storage, and $900 for the regulatory sexually transmitted infection testing. Screening document review is $250, and $150 every six months after that.

The Known Donor account differs from the bank’s Directed Donor account in one respect that drives the cost: the recommended six month quarantine is waived, and in exchange STI testing has to be completed within seven days of every sample collected, at $900 each time. The Directed Donor route keeps the quarantine, starts at $3,050, and requires an exit blood draw at least six months after the last collection, also at $900. The bank notes that some fertility clinics will not accept vials that have not been quarantined, so the choice is worth confirming with the clinic first. All figures are from the bank’s published sperm storage fees page as it stood in July 2026, and they are one bank’s prices rather than a California average.

On the catalog side, the same bank lists program donor sperm at $2,500 per IUI vial and $2,300 per ART vial, with a $100 recipient registration fee. Clinic charges for monitoring and insemination sit on top of any of these numbers, and our national breakdown of donor sperm cost works through the per cycle arithmetic. A known donor changes the cost structure without removing it, because testing, any clinic involvement, and the paperwork still cost money when there is no vial to buy.

California’s parentage statute says nothing about money, and payment does not change whether Section 7613(b) applies. What people actually pay a known donor in California is not published anywhere reliable, and figures circulating in groups are not a source we would treat as one.

Does insurance cover any of this in California?

Some of it, for some people, starting January 1, 2026. California Senate Bill 729, signed in 2024, requires fully insured large group health plans covering 101 or more employees to cover the diagnosis and treatment of infertility, including in vitro fertilization.

The law was originally set to take effect on July 1, 2025 and was pushed back to January 1, 2026 by Assembly Bill 116, signed on June 30, 2025. Coverage under SB 729 includes up to three completed oocyte retrievals with unlimited embryo transfers, subject to clinical guidelines. The bill also broadens the definition of infertility so that it reaches people who need donor sperm for reasons that are not medical, including same-sex couples and single people building a family by choice.

The exclusions are large and they matter more than the headline. SB 729 does not reach self-funded employer plans, small group plans, individual market plans, or Medi-Cal, and self-funded plans are regulated federally rather than by the state. Anyone counting on the mandate should confirm with their plan whether it is fully insured and large group. People arriving at this question as a solo parent will find the wider picture in our guide for a single mother by choice.

How does a second parent get recognized in California?

Through a Voluntary Declaration of Parentage signed at the hospital or afterward, or through a court judgment. Since January 1, 2020, following Assembly Bill 2684, the declaration has been available to intended parents of a child conceived through assisted reproduction, including a parent with no genetic connection to the child.

The declaration is free and is offered at the hospital after birth. It is available to two people, married or unmarried, who had a child through assisted reproduction using donated sperm or eggs, where the donation did not come from one of them. It is not available where a surrogate carried the child, where there is uncertainty about whether the child was conceived by donation or by intercourse, or where someone who did not originally intend to be a parent has changed their mind.

Many California families obtain a court judgment as well, because a state administrative document is treated differently across state lines than a court order under the Full Faith and Credit Clause. The general US picture on that choice is in our article on second-parent adoption and the VAP. California also has a simplified confirmatory adoption route for a parent who is already recognized, and which of the three fits depends on marital status, travel plans, and how the child was conceived.

Where do people look for a known donor in California?

Most searching happens in the four population centers: Los Angeles and Orange County, the San Francisco Bay Area, San Diego, and the Sacramento region. California reports more fertility clinics to the CDC’s national assisted reproductive technology surveillance than any other state, and most of them sit in those same regions.

Distance matters more in California than the state’s clinic count suggests. A donor in Sacramento and a recipient in San Diego are roughly 500 miles apart, which rules out the fresh sample timing that people in one metro area take for granted and pushes the arrangement toward a licensed bank and shipping. Timing a cycle across that distance is the practical constraint rather than the legal one, and timing and ovulation covers what the window looks like.

Facebook groups, dedicated platforms, and word of mouth all operate in California, with the same trade-offs as anywhere in the country. Our comparison of Facebook groups and platforms sets out what each format does with identity, moderation, and record keeping, and readers looking at a second large state with a modern statute may want the New York picture alongside this one.

On our side of it, sperm-donation.com is where people create a profile, search, and message each other. Everything in this article that involves a form, a test, or a clinic happens between the people involved and the professionals they choose.

Frequently asked questions

The short version

California gives a private arrangement something most states do not, which is a statutory route that works without a clinic. Family Code Section 7613(b)(2) treats a known donor as not the natural parent where a written agreement was signed before conception, and Section 7613.5 publishes a free form built for exactly that. Signing it before conception costs a notary fee. Skipping it leaves a judge to weigh clear and convincing evidence about a conversation.

The second layer is the one people underestimate. Section 7613(b) closes the biological route to parentage and leaves the conduct route open, and a California appellate court has applied that distinction against a donor who acted as a father after birth. Families planning ongoing contact are describing the fact pattern that case turned on, so the conversation about contact belongs before conception.

The third layer is money, where California is expensive on the licensed route and where the new insurance mandate helps a real but limited group. If you are working out which route fits, our guides on finding a known sperm donor in the US and on donor agreements state by state are the natural next reads.
