The eleven percent that existed only as a family understanding

The situation

Zainab found out how exposed her ownership really was three weeks before her sister's company was supposed to close a sale, when Mona called to say the buyer's lawyer had asked a question neither of them could answer cleanly: who exactly owned the eleven percent of the business that was not registered in Mona's name? Zainab was an elementary school teacher, not the operator of the HVAC service company Mona had built over two decades from a one-van operation into a crew of thirty technicians across the Peterborough region. But she had lent Mona money in the company's early years, and in return she had held a minority stake that existed mostly as a family understanding rather than a paper trail: a handshake, an old note in a notebook, a few years of unequal dividend payments that did not match any share register anyone could produce.

It had never mattered until a private equity-backed platform, looking to add Mona's company onto a larger HVAC roll-up it was assembling across Central Ontario, sent its deal team in to do proper diligence. The transaction itself was straightforward on its face: a sponsor-backed platform, run by an operating partner named Tariq, wanted to acquire the company for a price in the neighbourhood of twenty million dollars, structured as a mix of cash at close and a rollover of part of Mona's proceeds into equity of the platform itself, sized to keep Mona engaged running the combined business after closing. None of that rollover mechanics touched Zainab directly. What touched her was simpler: if the buyer could not confirm who actually owned the eleven percent everyone had assumed was Mona's to sell, Zainab's claim to be paid for her share risked disappearing into the transaction that was supposed to cash her out of it.

Three years earlier, when Mona first restructured the business ahead of a financing round that never closed, our office had told Zainab directly, in a conversation Mona was part of, to formalize her stake with a proper shareholders' agreement and updated share certificates. Zainab had agreed it was sensible, trusted her sister, and let it slide as the two of them kept splitting distributions the way they always had. The gap sat there quietly for three years until a buyer's diligence team went looking for exactly this kind of thing, and Zainab called us back with three weeks left before a closing she had no control over and every reason to worry would happen without her getting paid what she was owed.

The complication

The buyer's counsel had flagged the problem the way diligence lawyers usually do: politely, in writing, with a deadline attached. Their review of the minute book had turned up a share register that did not reconcile with historical tax filings, dividend records that implied an ownership split the corporate documents did not show, and no shareholders' agreement at all. From the buyer's side, this was not a minor housekeeping item. If eleven percent of the company belonged to someone whose ownership had never been properly issued or documented, the seller could not deliver clean title to one hundred percent of the shares, which the purchase agreement required.

For Zainab, the complication cut a different way than it did for Mona. Mona's incentive, understandably, was to get the deal closed on schedule; a dispute over exactly how much of the company Zainab owned was a delay Mona did not want and, if it dragged on, a risk to the price and the rollover terms she had personally negotiated with Tariq's team. Zainab's incentive was to make sure that whatever got resolved in the next three weeks resolved in her favour, permanently, on paper, before the deal closed and the company she had a claim against ceased to be independently hers to claim against at all. The two sisters wanted the same broad outcome, but they were not, in that moment, aligned on the details, and a shareholder confirming a claim against a company her own sister is about to sell is not a negotiation one lawyer can run for both of them at once without shortchanging someone.

That mismatch mattered practically, not just in principle. If Zainab simply deferred to whatever number Mona and the buyer settled on, she had no independent confirmation that the figure reflected what she was actually owed, and no protection if closing pressure led to her stake being rounded down, deferred past closing on a promise to sort it out later, or folded into Mona's rollover in a way that suited the deal timeline more than it suited her. Because the rollover was calculated using Mona's expected proceeds from the full sale price on the assumption that the eleven percent flowed through her, an unresolved ownership question was not an abstraction for Zainab. Left unaddressed, it was money that could quietly end up inside a rollover stake she had never agreed to hold, since she was not the one staying on to run the combined business, and had no interest in her payout being tied to a platform's future performance instead of paid to her outright.

What we did

1. Confirmed we were acting for Zainab alone, and said so plainly. Given that Mona had her own deal counsel negotiating price and rollover terms with Tariq's team, we made clear from the first call that our role was to protect Zainab's ownership claim specifically, not to broker a compromise. That mattered, because a lawyer trying to represent both sides of a dispute over how much stock belongs to whom cannot actually advocate for either one.
2. Reconstructed the ownership history from source documents. We pulled every tax return, dividend record, and bank statement covering the period Zainab had been receiving distributions, and mapped what those payments implied about her actual economic interest in the company, since no contemporaneous share issuance had ever been filed to formalize it. Two of the earlier distributions had been recorded as consulting fees rather than dividends, which meant tracing them through both the company's books and Zainab's personal tax filings before the pattern held together as a consistent claim.
3. Negotiated the confirmed figure directly with Mona's counsel. Once the evidence supported a genuine eleven percent economic interest dating back roughly a decade, we took that position to Mona's lawyer rather than asking Zainab to simply accept whatever Mona was comfortable acknowledging in the moment, because a figure agreed to informally between sisters under deadline pressure is exactly the kind of number that gets revisited later, after the money has already moved and the leverage to fix it is gone.
4. Insisted on proper share issuance before, not after, closing. We prepared and required the filing of the share certificates and corporate resolutions that should have been done three years earlier, so Zainab's ownership existed on paper before the sale closed rather than as a promise to fix it afterward, when her leverage to insist on accuracy would have disappeared along with the deal team's attention.
5. Secured Zainab's payout in cash, separate from Mona's rollover. We pushed to have Zainab's eleven percent carved out of the purchase price and paid entirely in cash at close, rather than swept into the rollover structure being negotiated for Mona, since Zainab had no operating role with the buyer's platform and no reason to accept deferred, contingent value in place of money she was already owed.
6. Reviewed the tax treatment of her cash-out independently. A lump sum payment on a stake that had never been formally issued raised its own reporting questions, distinct from however the transaction's overall tax structuring treated Mona's larger and differently structured proceeds, so we confirmed separately that Zainab's payment was characterized correctly before it was reported to either sister's satisfaction.
7. Put an interim governance agreement in place. Since closing could not happen instantly once ownership was confirmed, we negotiated a short agreement covering the weeks between resolving Zainab's stake and completing the sale, so decisions the company needed to make in the meantime, including a supplier contract renewal that could not wait, could not later be used to quietly dilute or complicate what had just been established.
8. Confirmed the final closing documents reflected the correction. Before anything was signed, we reviewed the final purchase agreement and closing statement line by line to confirm Zainab's cash payment, its amount, and its independence from Mona's rollover were reflected exactly as negotiated, rather than trusting that a correction agreed to weeks earlier had carried through every draft that followed it.

The outcome

The deal closed roughly five weeks later than originally scheduled, after the extra time needed to formalize Zainab's ownership and separate her payout from the rest of the transaction. The final price held at the originally negotiated level; the sponsor did not use the diligence finding as leverage to cut it, in part because the correction was thorough and the underlying business performance had never been in question. Zainab received her eleven percent entirely in cash, properly taxed and properly documented, independent of whatever Mona ultimately agreed to with Tariq's team on the rollover.

What Zainab avoided was the quieter risk: being asked, under closing pressure, to accept an informal number, or to let her stake be absorbed into a rollover she had no say in and no interest in holding. Her ownership now rests on a share certificate and a corporate resolution instead of a shared memory, and the eleven percent she was owed could not be renegotiated later by anyone's convenience, including her sister's.

For Zainab, the harder lesson was the one she had already been given once. The formalization she had agreed was sensible three years earlier, and then let slide out of trust, did not end up costing her the money, but it cost weeks of pressure at the worst possible time and forced a conversation about money between sisters that neither wanted to have under a closing deadline. She has since asked our office to confirm her ownership documentation is current every year, rather than waiting for the next transaction to surface what should have been fixed long before.

The relationship between the sisters survived the deal, though not without strain. Mona's rollover came in smaller than originally structured once Zainab's confirmed share was carved out of its base, and Mona has said since that she wishes they had simply done the paperwork years earlier. For Zainab, the outcome was simpler: a stake that had existed only as an understanding between sisters became, finally, hers on paper, paid in full, before the company that carried it changed hands for good.
