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, but perhaps not in the way Kajan first assumed. Ontario's parentage law, set out in the Children's Law Reform Act as rewritten by the All Families Are Equal Act, 2016, already presumes that a birth parent's spouse at the time of conception is a parent, automatically, without needing a written agreement or a genetic connection. That presumption is rebuttable, though: it falls away if it can later be proven that, before conception, the spouse did not consent to be a parent, or consented and then withdrew that consent. A presumption is only as solid as the evidence behind it, and nothing in Kajan and Abirami's file, no agreement, no clinic paperwork, no contemporaneous written record of who intended what, supplied that evidence if the presumption were ever put to the test.

Kajan and Abirami had no such agreement, and the children's birth registrations, completed years earlier, did not list Kajan as a parent, an administrative gap that had never mattered while the marriage was intact and nobody was asking. That gap did not necessarily mean Kajan was not a legal parent; the spousal presumption likely already made Kajan one, automatically, from the moment each child was born. But being likely already a parent under a rebuttable presumption that had never been tested or documented is a far shakier position to be in during a separation than parentage confirmed by a signed agreement or a court order, despite Kajan having co-parented the children from day one.

This was not an abstract problem. Two things followed from it. First, if Kajan's parentage was ever challenged, on the consent question or simply because nothing on paper matched the presumption, it could affect Kajan's standing to seek parenting time and decision-making responsibility on the same footing as Abirami during the separation. Second, Thao's own protection from being treated as a parent, which the law also extends automatically to a sperm donor whose material is used for insemination, rested on that same undocumented history: nothing in writing confirmed the method of conception or Thao's intentions at the time. That left a narrow but real door open for a future dispute about what had actually happened and what everyone had actually intended, something neither spouse wanted and Thao had never sought, but a possibility that needed to be closed off formally rather than assumed away. A friendly understanding is not the same as a documented one, 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, though likely already arising automatically under the spousal presumption, had never been formally documented, tested, or confirmed by a court. 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. Rather than leave Kajan's status resting on an untested presumption during an already difficult separation, 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 on different terms, or worse, negotiating from a position of doubt about Kajan's standing that Abirami's side could have used as leverage even without intending to.
5. Negotiated the parenting schedule and appraised the family property. With parentage confirmed, we moved to a parenting schedule reflecting the equal role both spouses had played since the children were born, then turned to dividing the family property. Kajan's rental portfolio was independently appraised by a qualified valuator, since a portfolio of income-producing commercial buildings cannot be priced from a market estimate the way a single home can, and the appraisal became the agreed starting figure for everything that followed.
6. Calculated the equalization payment. The couple's respective net family properties came to 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.
7. 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, and so a future change in either spouse's income could be addressed under support rules without reopening the property settlement.

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.
