When a Donor-Conceived Family's Paperwork Wasn't Finished

The situation

Kajan and Abirami married in Ontario and spent the next several years building both a family and two separate careers. Kajan owned and managed a small portfolio of commercial rental properties around Leamington. Abirami worked as a surgeon. Neither income needed the other to get by, but together they had accumulated a household net worth well into seven figures: the rental buildings, a matrimonial home, retirement savings, and investment accounts.

Their two children were conceived through home insemination using sperm from Thao, a close friend of the couple who agreed to act as a known donor. Abirami carried both pregnancies. The arrangement was informal and friendly — Thao attended birthdays, was introduced to the children as an honorary uncle, and never asked for parenting time or decision-making input. Everyone involved understood, in the way families often do, that Kajan and Abirami were the parents and Thao was not. Nobody put that understanding in writing before the children were conceived.

Eight years into the marriage, the relationship broke down. Kajan and Abirami agreed the marriage was over and began trying to sort out parenting arrangements and finances between themselves before involving lawyers. It was during those early conversations that Kajan raised a question that had never come up before: whose name was actually on the children's legal parentage, and did it matter now that the family was separating.

The parentage gap

It mattered a great deal. Ontario's All Families Are Equal Act, 2016 sets out how legal parentage is determined for children conceived through assisted reproduction, including donor insemination. Where a birth parent's spouse intends to be a legal parent and there is no genetic connection, the Act generally expects a written pre-conception parentage agreement, signed before the child is conceived, confirming who intends to parent and confirming that a known donor does not. Where that agreement was never signed, the non-birth spouse's parentage is not automatically secured and may need to be established later through a court application for a declaration of parentage.

Kajan and Abirami had no such agreement. Because Abirami gave birth, she was recorded as a parent without difficulty. Kajan's status was murkier. On paper, depending on how the birth registration had been completed years earlier, Kajan's legal parentage of the children was not conclusively documented — despite having co-parented them from day one.

This was not an abstract problem. Two things followed from it. First, if Kajan's parentage was ever challenged, it could affect Kajan's standing to seek parenting time and decision-making responsibility on the same footing as Abirami during the separation. Second, because Thao had provided the sperm and had an ongoing relationship with the children, an unconfirmed parentage record left a narrow but real door open for Thao to later assert a parental claim — something neither spouse wanted, and something Thao had never sought, but a possibility that needed to be closed off formally rather than assumed away. A friendly understanding is not a legal status, and separations have a way of surfacing exactly the gaps that a good relationship had let everyone ignore.

What we did

1. Confirmed the parentage gap before touching anything else. Before any parenting schedule or property discussion could proceed on solid footing, our team reviewed the children's birth registrations and confirmed that Kajan's legal parentage had never been formally established. This was treated as the priority item, ahead of the property and support negotiations Kajan and Abirami had already started discussing informally.
2. Applied for a declaration of parentage. We brought an application asking the court to formally declare Kajan a legal parent of both children, supported by affidavit evidence of the couple's shared intention from before conception: the joint decision to have children, the joint parenting since birth, and the absence of any donor agreement or conduct suggesting otherwise.
3. Secured Thao's written confirmation. We asked Thao to provide a sworn statement confirming he had never intended to parent the children, had no genetic parentage claim he wished to pursue, and supported the declaration naming Kajan as a parent. Thao agreed without hesitation. Having this in writing, rather than relying on years of friendly understanding, removed the single biggest source of risk in the file.
4. Kept the parenting and property talks paused until parentage was resolved. We advised against finalizing any separation agreement provisions about parenting time or child support until Kajan's legal parentage was confirmed by the court. Negotiating those terms on an uncertain legal foundation risked having to revisit them later, or worse, negotiating from a position of doubt about Kajan's standing.
5. Negotiated the separation agreement once parentage was settled. With parentage confirmed, we moved to a parenting schedule reflecting the equal role both spouses had played since the children were born, and to dividing the family property. Kajan's rental portfolio was independently appraised, and the couple's respective net family properties were calculated: roughly $1.9 million for Kajan, after deducting mortgage debt on the rental buildings, and roughly $1.3 million for Abirami, including the matrimonial home equity and retirement savings. Under the Family Law Act's equalization framework, the spouse with the higher net family property owes the other half the difference between the two figures. Here, that difference was about $600,000, producing an equalization payment of roughly $300,000 from Kajan to Abirami, paid in part through a lump sum and in part by refinancing one of the rental properties.
6. Addressed spousal support separately from the property division. Given the income gap between a surgeon's earnings and rental income, we negotiated a time-limited spousal support arrangement reflecting the length of the marriage and the disparity in earning capacity, kept distinct from the equalization payment so neither side mistook one obligation for a substitute for the other.

The outcome

The declaration of parentage was granted several months after the application was filed, confirming Kajan as a full legal parent of both children with no further ambiguity. Thao's cooperation meant the application went through without opposition, but the family still lived with months of legal uncertainty during a period that was already emotionally difficult — uncertainty that a signed agreement, years earlier, would have avoided entirely.

The separation agreement that followed gave both spouses a shared parenting schedule and resolved the finances cleanly: the roughly $300,000 equalization payment, spousal support on a defined term, and clear title to the rental portfolio in Kajan's name going forward. Nobody's parenting rights were ultimately contested, and Thao never sought any role beyond the one he had always had as a family friend.

This is what a mitigated outcome looks like in family law: the worst-case scenario — a contested claim to parentage or custody involving a third party, dragged out during an already difficult separation — never materialized, because the gap was caught and closed before it could be exploited or misunderstood. But it was not free. The family paid legal costs and lost months to a process that a single signed document, completed before the children were conceived, would have made unnecessary. Acting properly limited the damage; it did not erase the fact that the damage was avoidable in the first place.
