When a Known Donor Is Treated as a Parent
Statutes say a donor is not a parent. Several of them then attach conditions about how the donation was made and what the parties signed, and conduct after the birth can matter as much as anything the parties arranged before conception.

The rule in short
Parentage statutes provide that a donor is not a parent of a child conceived through assisted reproduction. Some states apply the exclusion unconditionally; others condition it on the gametes having been provided to a licensed physician or sperm bank, or on a writing signed before conception. Where the donation was informal, courts examine intent and later conduct, and a donor who lived with the child and held the child out as his own may be found a parent.
The rule everyone remembers is that a donor is not a parent. It is accurate as far as it goes. What produces litigation is the part underneath: whether the arrangement in question satisfies the statute's definition of a donation, and whether what happened after the birth created a parentage claim that has nothing to do with donor status.
The rule and its conditions
States take two approaches. In the uniform model the provision is short and unconditional: a donor is not a parent of a child conceived by assisted reproduction. There is no requirement that a physician be involved and no requirement of a written agreement to achieve the exclusion.
California takes the conditional approach. A donor of semen 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 is treated as not being the natural parent, unless the donor and the woman signed a written agreement before conception that the donor would be a parent.
Where the semen was not provided that way, the same statute supplies alternative routes to the exclusion: a written agreement signed before conception that the donor would not be a parent, or a court finding by clear and convincing evidence that the child was conceived through assisted reproduction and that the parties had a pre-conception understanding to that effect.
The difference matters most for arrangements between friends. In a conditional state, a private donation with nothing in writing sits outside the safe harbor and the outcome depends on proof of intent.
What assisted reproduction means
Every one of these provisions applies only to assisted reproduction, and statutes define the term to exclude conception by sexual intercourse. The definition typically covers intrauterine or intracervical insemination, donation of gametes or embryos, in vitro fertilization and embryo transfer.
Conception by intercourse falls outside the framework entirely. The ordinary parentage rules apply, and an agreement that the man will not be treated as a parent is generally unenforceable, because the obligation of support belongs to the child rather than to the adults who agreed about it.
Home insemination usually falls inside the definition, which is why the conditional states matter so much. The method is assisted reproduction, but the gametes were not provided to a licensed physician or a bank, so the safe harbor turns on the writing.
| Arrangement | Uniform-model state | Conditional state |
|---|---|---|
| Anonymous donation through a licensed bank | Donor is not a parent | Donor is not a parent |
| Known donor, gametes provided to a physician, no writing | Donor is not a parent | Donor is not a parent |
| Known donor, home insemination, signed pre-conception agreement | Donor is not a parent | Donor is not a parent |
| Known donor, home insemination, nothing signed | Donor is not a parent by statute | Turns on proof of pre-conception intent |
| Known donor who later lived with and raised the child | May be a parent on other grounds | May be a parent on other grounds |
| Conception through intercourse | Outside the donor provisions | Outside the donor provisions |
Even in a state where the donor provision is unconditional, a person can become a parent by a route that does not depend on donor status. Consenting to assisted reproduction with the intent to be a parent creates parentage. So does residing with the child and openly holding the child out as one's own for the period a statute specifies. A donor who moves in, is called dad and appears at school as a parent is not relying on donor status; he is building a different claim.
Consent and the writing that establishes it
The mirror image of the donor question is how an intended parent who did not give birth becomes a parent. The uniform model provides that an individual who consents to assisted reproduction with the intent to be a parent of the resulting child is a parent, and requires that consent to be in a record signed by the person giving birth and by the intended parent.
Failure to sign is not fatal. Statutes permit a court to find consent where a party proves by clear and convincing evidence an express agreement entered into before conception that both would be parents, or where the parties resided together with the child for the first several years of the child's life and both openly held the child out as their own.
Those alternatives are the provisions that decide most contested cases. They also explain why the same facts can produce opposite results depending on the state: a couple who separated shortly after a birth may satisfy the pre-conception agreement route and fail the holding-out route, or the reverse.
What the child may later ask for
A separate set of provisions deals with information rather than status. Recent statutes require gamete banks and fertility clinics to collect identifying and medical information about donors, to ask each donor whether identifying information may be released when a resulting child reaches adulthood, and to keep the records for a defined period.
Where a donor agreed to release, the information is disclosed on request once the person conceived reaches the age the statute sets. Where the donor declined, medical history is usually still available in non-identifying form, and some statutes require a bank to make a good faith effort to contact the donor with a later request.
These provisions do not change parentage. A donor whose identity is disclosed is still not a parent, and disclosure creates no support obligation and no right to contact. They matter because they are the reason a private arrangement with no records leaves the child with nothing to ask for later, which is a consideration separate from the legal risk to the adults.
How informal arrangements fail
The recurring pattern is an arrangement that worked until it did not. Friends agree that one will donate and will have no legal role but will be present in the child's life. Nothing is signed because the agreement feels clear. Years later the relationship between the adults deteriorates, or a support claim is filed, or the donor wants more contact than the parents want to give.
At that point the court is asked to reconstruct intent from conduct, and conduct usually points in several directions at once. Who was listed on the school forms, who provided money, who was introduced as what, who attended medical appointments. None of it was arranged with a later dispute in mind.
The failures are avoidable at low cost. A pre-conception writing that states the parties' intent, executed by everyone involved, satisfies the conditional statutes and is strong evidence in the others. Using a licensed physician or a bank, where feasible, satisfies the safe harbor in states that require it. And where the parties actually intend shared parentage, saying so in the record produces a more reliable result than an unwritten understanding.
Where a second parent's status is intended, the routes that produce a judgment rather than a presumption are described in obtaining a parentage order, and where a surrogate is involved the framework in the requirements for an enforceable agreement applies. Where no framework fits, families sometimes use a second-parent adoption, which brings the requirements in the study and its disqualifying findings into play.
Points to carry away
- The general rule in parentage statutes is that a donor is not a parent of a child conceived by assisted reproduction.
- Several states condition the exclusion on the gametes being provided to a licensed physician or a licensed sperm bank.
- Where the donation was private, some states require a written agreement signed before conception.
- A court may find consent to parentage without a writing on clear and convincing evidence of a pre-conception agreement.
- Living with the child and openly holding the child out as one's own can establish parentage independently of donor status.
- Sexual intercourse rather than assisted reproduction places the arrangement outside the donor provisions entirely.
Questions readers ask
Does a donor agreement have to be notarized?
Statutes differ. Where a state conditions the donor exclusion on a written agreement, the usual requirement is a record signed by the donor and by the person who will give birth, executed before conception. Notarization is not always required by the parentage statute, though it is common practice and it removes an easy line of attack on the document. What matters more than the form is the timing: an agreement signed after conception generally does not satisfy a statute that specifies a pre-conception writing.
Can a donor agree to have parental rights?
Yes, in states whose statutes permit it. Several provide that a donor is not a parent unless the donor and the person conceiving signed a written agreement before conception that the donor would be a parent. That structure lets the parties choose the outcome expressly. Where three adults intend to share parentage, some states now permit a court to adjudicate more than two parents, but that is not available everywhere, and an agreement cannot create a status the state's law does not recognize.
What if conception occurred through intercourse?
The donor provisions apply to assisted reproduction, which statutes define to exclude conception by sexual intercourse. Where conception occurred that way, the ordinary parentage rules apply and any agreement that the man would not be a parent is generally unenforceable, because a parent cannot contract away a child's right to support. Parties who intend an arrangement to be governed by the donor provisions should ensure the method of conception falls within the statutory definition.

Getting a Parentage Order Entered Before Birth
In states with an enabling framework, a party to a surrogacy agreement may seek an order declaring each intended parent to be a parent, declaring the person who gave birth and any spouse not to be parents, and directing the registrar to record the intended parents on the birth record. The court may issue the order before birth and stay enforcement until delivery. Other states enter an order only after birth, sometimes on an expedited timetable measured in days.
The Revocation Window After Consent Is Signed
Consent statutes set a minimum interval after birth before a birth parent may sign, then a revocation period measured either in days or by reference to court approval. Some states make consent binding on execution for a newborn and allow only fraud or duress as a later challenge. Others allow a fixed number of days, or a waiver of the right to revoke signed with counsel. Federal law adds a separate rule where the child is an Indian child.
The Putative Father Registry and the Deadline Running Against It
Most states maintain a registry where a man who believes he may have fathered a child files identifying information to preserve a right to notice of an adoption or termination proceeding. Registration does not establish paternity and confers no custody. Deadlines are short, commonly measured from the child's birth or from the filing of a petition. A certificate that a search found no filing lets a court proceed without notice to any unregistered man.
