Here's the thing nobody tells you when you start down the donor-conception road: the most important step often isn't medical. It's legal. A clear donor agreement made before insemination helps protect your family (your child, your partner, and your donor) from confusion, crossed wires, and painful assumptions later on.
This page is general information, not legal advice. Every family's situation is different, and NZ law has specific requirements. Please talk to one of the qualified family lawyers below before acting.
What a donor agreement actually does
A donor agreement is a written document, usually prepared before conception, that records everyone's intentions. In New Zealand, it may not override the law or bind a court, but it can still be a very important record of what everyone understood and agreed to at the start.
It typically covers:
- Role clarity: is this person a donor, a known donor with contact, or an intended co-parent?
- Contact: what relationship, if any, will the donor have with the child
- Legal parentage: who is intended to be recognised as the child’s legal parent or parents
- Future children: whether the same donor may be used again
- Financial: confirming no payment for sperm, while clarifying reasonable expenses
When you actually need a lawyer
You don't always need a lawyer to when trying to conceive using donor sperm, plenty of people don't use one. But you should strongly consider legal advice if any of these apply:
- You're using a known donor, such as a friend, family connection, or community introduction
- You want your partner recognised as the second legal parent
- Your donor wants some form of ongoing relationship with the child
- You're entering any kind of co-parenting arrangement
- You're using donor sperm outside a clinic setting
- You're considering surrogacy, donor eggs, embryo donation, or a more complex family-building pathway
The paperwork can feel unromantic in the moment but it’s one of the most loving things you can do for your future child.
The New Zealand legal basics, in plain English
Under NZ's Status of Children Act, if you conceive via insemination (not intercourse) and the birth mother is in a marriage or civil union, her partner is generally recognised as the second legal parent from birth and the donor is generally not a legal parent. But this clean outcome depends on the donation being by insemination and ideally backed by a written agreement.
This is exactly why home insemination (rather than natural conception with a donor) matters legally, and why getting the agreement signed before you start is so important. The details get nuanced fast, which is what the lawyers below are for.

What to ask when you call
- "Do you offer a fixed fee for a donor agreement, or is it hourly?"
- "Have you worked with families in my exact situation before?" (solo, same-sex, known donor, etc.)
- "Will both intended parents and the donor each need separate advice?"
- "How long does the whole process usually take?"
- "What do you need from us before we inseminate?"
A note on timing: get legal advice before your first insemination, not after. The earlier you have the conversation, the easier it is to make sure everyone is clear, protected, and on the same page.
