Parentage disputes after donor conception

Your family was built intentionally. The agreements were clear, the roles were defined, and everyone understood the plan. Then something shifted. Now you are facing a dispute about who is legally a parent to your donor-conceived child, and the answer is not as simple as biology.

These situations happen more often than people expect. A known donor decides they want a parental role. A co-parent argues they never consented. A recipient parent is unsure whether their partner is legally recognized. Or a birth certificate does not reflect what everyone agreed to.

BC's family law framework for donor conception is actually quite clear, and in most situations it protects families well. But when disputes arise, the details matter enormously. Here is what you need to know.

How BC law determines parentage after donor conception

In BC, the Family Law Act (FLA) governs who is and is not a legal parent when a child is conceived through assisted reproduction. Assisted reproduction is defined in the FLA as any method of conceiving a child other than sexual intercourse. This distinction matters a great deal.

The default rules under the FLA

When a child is conceived through assisted reproduction:

  • The person who gives birth is always a legal parent.
  • Their spouse or partner at the time of conception is also a legal parent, unless there is proof they did not consent to be a parent or they withdrew consent before conception.
  • A donor of sperm, eggs, or embryos is not a parent by reason of the donation alone.
  • A donor can only become a legal parent if there is a written pre-conception agreement that specifically says so.

Good to know

A co-parenting agreement is not the same as a separation agreement. It is drafted before the child is born, when everyone still agrees on the vision. That timing matters. Agreements made in goodwill, before conflict, are far more durable than ones negotiated in the middle of it.

This framework protects most families. Anonymous donors have no parental rights. Known donors who signed no agreement have no parental rights. Intended parents are recognized from birth.

The important exception: conception through sexual intercourse

BC's assisted reproduction rules only apply when a child is conceived through a method other than sexual intercourse. If conception occurs through sexual intercourse, even with a known donor who agreed not to parent, the biological father is treated as a legal parent under the FLA.

This is sometimes called the 'that's a donor not a dad' problem. No informal agreement can override it. If your child was conceived through intercourse with a known donor, BC law currently treats that person as a legal parent regardless of what was agreed. A formal legal process (typically adoption) would be required to change that.

Important

BC's Law Institute and provincial government have proposed changes to address this gap. But as of now, the rule stands. Always use a licensed clinic or assisted reproduction method, not sexual intercourse, when working with a known donor.

When parentage disputes actually arise

Even with BC's clear framework, disputes happen. Here are the scenarios we see most often.

A known donor claims they want to be a parent

This is one of the most emotionally complex situations. A friend or family member donated sperm or eggs. There was no written agreement, or the agreement was informal. Now they want contact, parental recognition, or formal legal status.

Under BC law, if the child was conceived through assisted reproduction and there was no written pre-conception agreement designating the donor as a parent, the donor has no legal parental status. The absence of a written agreement does not create uncertainty, it just means the donor is not a parent.

Courts in BC have upheld this framework consistently. Biology alone does not make someone a parent in an assisted reproduction context. Intention, documented before conception, is what matters.

An intended parent was not properly documented

Sometimes the intended co-parent is not recognized on the birth certificate, and the birth parent's partner later disputes the co-parent's status. Or a single recipient parent had a partner at the time of conception, but the partner claims they never consented.

These situations often come down to evidence of consent. Was the partner involved in the decision to conceive? Did they attend clinic appointments? Did they sign any clinic consent forms? BC courts look at the full picture when a dispute arises about whether a partner consented to being a parent.

Multi-parent families and agreements that were not formalized

BC law allows for more than two legal parents through assisted reproduction, but only when there is a written pre-conception agreement signed by everyone involved before conception. Families that planned to have three legal parents but did not formalize this in writing before the child was conceived will face real challenges.

Courts have used broad discretionary powers in rare cases to recognize additional parents outside the FLA framework, but this is not guaranteed and requires a court application. Do not count on it as a substitute for a proper written agreement.

Disputes following separation

When two parents who conceived through assisted reproduction separate, disputes about parenting arrangements, parenting time, and decision-making authority are governed by the same rules as any other BC family. Parentage was established at birth. Separation does not change who is a legal parent.

What changes is the need for a formal parenting arrangement that reflects the new reality. A final separation agreement or parenting plan can address parenting time, how decisions will be made, and how the child's relationship with their birth story will be handled as they grow.

What a parentage declaration is and when you need one

If there is genuine dispute or uncertainty about whether someone is a legal parent of a donor-conceived child, either the BC Supreme Court or BC Provincial Court can make a declaration of parentage under section 31 of the Family Law Act.

A declaration of parentage is a lifelong, immutable legal order. It formally establishes someone as a parent in law. This affects guardianship rights, parenting time, child support obligations, and a child's right to inherit.

When a declaration may be needed

  • A known donor seeks parental recognition and claims there was a pre-conception agreement.
  • An intended parent was not registered on the birth certificate and needs formal legal recognition.
  • There is genuine uncertainty about whether a partner consented to parentage at the time of conception.
  • A child was born outside BC and the home jurisdiction requires a court order rather than administrative registration.
  • An existing birth registration needs to be amended to reflect agreed or disputed parentage.

Good to know

No court order is required in most BC assisted reproduction situations if the legal steps were followed correctly before conception. If you followed the FLA framework, you can register as parents through BC Vital Statistics without going to court. A parentage declaration is for when something went wrong or is genuinely disputed.

The role of a pre-conception agreement

The single most effective way to prevent a parentage dispute after donor conception is a written pre-conception agreement, signed before the child is conceived.

This agreement documents the intentions of everyone involved: who will and will not be a parent, what role (if any) a donor will play in the child's life, and what obligations each party is taking on. It is not a guarantee that a court will do exactly what it says in every circumstance, but it is powerful evidence of what was intended.

A pre-conception agreement should address

  • Whether the donor is or is not intended to be a legal parent.
  • Whether the donor will have any ongoing relationship with the child, and on what terms.
  • The intended parents' roles, including both in a couple or all three in a multi-parent arrangement.
  • What happens if the relationship between intended parents ends before or after the birth.
  • Consent to the use of the donated material.

Good to know

A note on known donors: Even though BC law does not require a donor agreement for anonymous or clinic-based donations, we strongly recommend one for any known donor situation. It protects everyone, including the donor, from misunderstanding down the road.

BC Vital Statistics and birth registration

For most families in BC who followed the legal steps for assisted reproduction, birth registration is straightforward. There is no requirement to go to court. The birth parent registers the child, and their spouse or partner is registered as the second parent.

If there is a multi-parent agreement in place, the Vital Statistics Agency handles registration for those situations as well. If a surrogate carried the child, a different post-birth process applies.

Where disputes arise about who should appear on the birth certificate, a court application for a parentage declaration may be required before the Vital Statistics Agency will amend the registration.

What to do if you are in a dispute right now

If a donor is claiming parental rights, if your co-parent is being denied recognition, or if you are unsure whether your child's parentage is properly documented, the first step is to get clear legal advice quickly.

These situations can escalate. A donor who files a court application for a parenting time order or a declaration of parentage sets a legal process in motion that you will need to respond to. Acting early gives you more options.

Steps to take now

  • Gather every document you have: clinic records, any written agreements, correspondence with the donor, birth registration paperwork.
  • Do not agree to informal arrangements or contact while a dispute is unresolved. Get any agreement in writing.
  • Speak to a BC family lawyer who works in fertility and reproductive law. This is a specialized area and the details matter.
  • If a court application has been filed against you, respond within the required timelines. Missing a deadline can have real consequences.

What happens without an agreement

Without a written co-parenting agreement, the Family Law Act's default rules apply. Both parents who have lived with the child are guardians. Decision-making authority is shared. Parenting time is whatever the parents informally agree to, until they do not agree anymore.

When informal arrangements break down, the parties end up in negotiation or court, trying to establish what everyone intended from the beginning. That process is expensive, slow, and hard on children. It is also completely avoidable.

The families who need a co-parenting agreement the most are often the ones who feel they need it the least, because everything seems fine right now. An agreement is not a sign of distrust. It is a sign that both parents are serious about doing this well.

Parentage Disputes after Donor Conception

Real questions. Straight answers. No legal jargon required.

If your child was conceived through assisted reproduction at a clinic or using a non-intercourse method, BC law says a donor is not a parent simply by reason of donation. An informal agreement that was not written down still leaves the donor without legal parental status in an assisted reproduction context. However, if conception occurred through sexual intercourse, the law applies differently and the biological father may be treated as a legal parent regardless of your agreement. Get legal advice quickly to understand exactly where you stand.

No. Under BC's Family Law Act, parentage through assisted reproduction is not based on biological connection. If your partner was your spouse or in a marriage-like relationship with you at the time of conception and consented to be a parent, she is a legal parent. The fact that donor eggs were used does not change that. The birth certificate may already reflect this. If there is a dispute, evidence of her consent at the time of conception is what matters.

A written pre-conception agreement designating a donor as an intended parent is exactly what BC law requires to give a donor legal parental status. Under the FLA, you can have more than two legal parents through assisted reproduction if that was the documented intention before conception. You should still confirm the birth registration reflects all intended parents correctly. If it does not, a parentage declaration from the court may be needed to formalize what your agreement set out.

Yes, and this is not optional. Independent legal advice for the surrogate is a foundational requirement of a sound surrogacy arrangement. Each party needs their own legal counsel to ensure the agreement is fair, informed, and enforceable.

TIf your child was conceived through assisted reproduction and there was no written pre-conception agreement making the donor a parent, he is not a legal parent under BC law. He has no automatic right to parenting time or contact. However, if he files a court application, you will need to respond. A court will not grant parenting time to someone who is not a parent and has no established relationship with the child simply because they are a biological donor. Document everything, do not engage informally, and speak with a family lawyer who can help you respond from a position of strength.

BC's Family Law Act covers embryo donation as part of its assisted reproduction framework. Neither the genetic contributors to the embryo nor the donors are automatically parents if the proper steps were followed. The birth parent and their spouse at the time of conception are the legal parents. Embryo donation is treated the same as sperm or egg donation under the FLA in terms of parentage. That said, embryo donation involves additional layers of consent and documentation. We recommend confirming your specific situation with a BC fertility law practitioner to make sure your birth registration and any agreements are properly in order.
