Known Donors, Surrogates, and the Agreements That Protect Everyone

Educational, not legal advice. Donor and surrogacy law is intensely state-specific and turns on details (physician involvement, timing, marital status). Work with an assisted-reproduction attorney in your state.

If a known donor, surrogate, or gestational carrier helped build your family, the law's default answers may not match your intentions — and clearing that up is best done in writing, early.

Many states treat a sperm donor who donates through a licensed physician as having no parental rights or child-support obligations. But donate informally — or in a state without a clear statute — and a known donor can later be found to be a legal parent, or be pursued for support. A signed known-donor agreement, ideally executed before conception, records that the donor is a donor and not a parent, and that the intended parents are the parents.

A gestational carrier is not the intended parent, but states differ sharply on whether and how they enforce surrogacy agreements and pre-birth orders. Some are supportive; a few restrict or void compensated surrogacy. This is not a do-it-yourself area.

• Incorporate the signed donor or surrogacy agreement by reference, so the family's structure is documented.
• Confirm the intended parents and that the donor/carrier holds no parental role.
• Where a parentage judgment or pre-birth order was obtained, reference it and keep certified copies.

Clarity protects the child, the parents, and the donor. Without it, a relationship that felt settled can be reopened years later — over custody the donor never wanted, or support a parent never expected to seek.

Two moms conceive at home with sperm from a close friend. Everyone is warm and informal; nobody signs anything, because paper feels unnecessary between people who trust each other. Eight years later the moms separate, money is tight, and one of them — or the state, in connection with public benefits — looks to the donor for child support. Or the friendship frays and the donor, who has been a beloved uncle-figure, petitions for parental rights. In states without a clear statute covering informal insemination, both claims can get traction, and the family spends years litigating a question a two-hour signing meeting could have answered. The agreement is not about distrust. It is about writing the answer down while everyone still agrees on it.

• A plain statement of intent. The donor is a donor and not a parent; the intended parents are the child's only parents.
• No support, no custody. The donor owes no child support and holds no custody or visitation rights, and the parents will not seek support from the donor.
• Contact, if the family wants it. Many families want the donor known to the child. Describe that contact as something the parents choose and shape — a relationship the child gets to have, not a parental right the donor holds.
• Medical history and future disclosure. How health information is shared, and what the child will be told, and when, about their origins.
• Practical mechanics. Confidentiality, what happens if the law changes, and a severability clause so one weak provision does not sink the rest.
• Independent counsel and timing. Each side reviews the agreement with their own attorney, and everyone signs before conception wherever possible.

• Start with an assisted-reproduction attorney in the state where the birth will occur, before any medical steps.
• Separate counsel for the carrier and the intended parents — an agreement where one lawyer represented everyone is far weaker.
• Execute the agreement before embryo transfer, covering compensation or expenses, medical decision-making, insurance, and contact after birth.
• Obtain a pre-birth or post-birth parentage order where available, so the intended parents are the legal parents from the start.
• Consider a confirmatory adoption afterward as belt-and-suspenders, especially for a non-genetic parent, so the tie rests on a judgment that travels.

• Conceiving first, signing later. Agreements executed after conception are weaker in many states, and after birth weaker still.
• Skipping the physician where the statute cares. In some states the donor-protection rule turns on physician involvement; a home insemination can fall outside it.
• Letting warmth substitute for paper. The families that end up in court are almost never the ones who expected to.
• Forgetting the parenting plan. When parents separate, the donor's role can become a proxy battle. Restating it in the plan closes that door.

• Does our state have a donor statute, and does our conception method fall inside it?
• Is our agreement enforceable here, and what would make it stronger?
• Do we need a parentage judgment or adoption on top of the agreement?
• If we move, does the analysis change — and should anything be done before we go?
• How should the parenting plan describe the donor or carrier if we separate?

If you are separating, the plan should restate what the agreement established: who the parents are, that the donor or carrier holds no parental role, and what contact, if any, continues. Neither parent should be able to enlarge or erase the donor's role unilaterally as a move against the other. Attach or reference the signed agreement, note where certified copies of any parentage order live, and keep both where each parent can produce them. Paper only protects you if you can find it when it matters.
