A Ninety-Day Notice Clause Almost Ran Out Unnoticed

The situation

Dragan had eleven days left when he called, and he knew it down to the date. Two years earlier he had sold his logistics company, a mid-sized trucking and warehousing operation he had built over almost two decades, to Ivan, a buyer who had structured most of the purchase price through a vendor take-back note — seller financing, in effect, where Dragan agreed to accept payments over five years rather than requiring the full amount at closing. The note was for roughly $1.1 million, secured against the business assets, with a clause allowing Dragan to demand the full remaining balance immediately if Ivan missed payments and did not cure the default within ninety days of written notice.

As part of the sale, Dragan had stayed on as an employee, managing dispatch and client relationships during a transition period both sides had agreed would help preserve the business's value. That arrangement had worked reasonably well for the first year. Then payments on the note started arriving late, then partial, then not at all for two consecutive quarters. Dragan's own review of his bank records, read against the note's acceleration clause, suggested the remaining balance now due was close to $860,000, though Dragan could not fully reconcile the number against the payment schedule in the note itself — some payments had come through an intermediary account tied to Anahit, Ivan's business partner in a separate venture, and Dragan was not certain every payment he had received had been properly credited against the right period.

Dragan had sent Ivan a written default notice roughly eighty days earlier, after the second missed quarter, starting the ninety-day cure clock. If the ninety days ran out without either a cure or a properly documented next step, Dragan risked losing the practical ability to demand the accelerated balance cleanly, and would likely have to pursue the missed payments piecemeal instead of as a single default.

Complicating the calculation, Dragan and Ivan's relationship, personal as much as professional, had deteriorated badly. Dragan still worked in the business daily, reporting to the person who owed him money and who he now believed was avoiding him. Both men had, by Dragan's account, said things to each other in the office that neither fully meant, and the dispute had become as much about the relationship as the money.

The gap nobody had noticed

The first task, with days rather than weeks available, was making sure the ninety-day notice deadline did not simply lapse. We reviewed the default notice Dragan had already sent and confirmed it met the note's requirements for triggering the cure period, then prepared a formal follow-up communication reserving Dragan's right to accelerate the full balance if the default was not cured within the remaining window, sent well before the deadline passed. That protected the legal position while the underlying numbers were still being sorted out.

The harder problem was the number itself. Dragan believed the accelerated balance came to about $860,000. Ivan's position, communicated through his own counsel once the dispute became formal, was that the true remaining balance was closer to $735,000, and that several of the payments Dragan was treating as missed had in fact been made through the account tied to Anahit, as part of an informal arrangement the two men had discussed but never fully documented in writing.

We requested full records for both the direct payments to Dragan and the payments routed through Anahit's account, and had them reconciled month by month against the note's payment schedule. The reconciliation found a gap nobody had noticed on either side: two payments made through Anahit's account had been recorded by Ivan's bookkeeper as applied to the note, but had actually been credited, due to a bookkeeping error, against a separate unrelated invoice between Ivan's company and a supplier Anahit also did business with. The money had been paid, but it had never actually reduced the note balance — it had gone somewhere else entirely inside Ivan's own books.

Once isolated, this explained almost the entire gap between Dragan's $860,000 figure and Ivan's $735,000 figure. It was not a dispute about whether Ivan owed the money in some general sense; it was a specific, traceable bookkeeping error that had misapplied roughly $120,000 in payments that were real but had never landed against the right debt — meaning the note balance was higher than Ivan's own books had led him to believe. That distinction turned an emotionally charged accusation of non-payment into a narrower, provable accounting question — which mattered a great deal given how personally the two men had come to take the dispute.

What we did

1. Confirmed the existing default notice and sent a protective follow-up before the deadline. With the ninety-day window closing and days rather than weeks to work with, the immediate priority was making sure Dragan's right to demand the accelerated balance was not lost to a technicality. We reviewed the original notice line by line against the note's own requirements for form and delivery, confirmed it complied, and sent a further letter reserving Dragan's rights well inside the remaining window — protecting the legal position before either side had agreed on a single dollar figure.
2. Requested full payment records from both the direct and intermediary accounts. Rather than arguing from Dragan's partial bank records alone, which covered only what had landed in his own account, we sought complete documentation of every payment made toward the note, including those routed through Anahit's account. Building the reconciliation from records both sides had to accept as authentic, rather than from memory or a partial paper trail, was what eventually made the numbers persuasive to Ivan's own counsel.
3. Reconciled the payment schedule month by month against both parties' figures. This line-by-line comparison, matching every payment against the note's amortization schedule rather than accepting either side's running total, isolated exactly where Dragan's and Ivan's numbers diverged instead of leaving the dispute as a general disagreement about how much was owed. It surfaced two specific misapplied payments as the entire provable source of the roughly $125,000 gap, turning a vague accusation into a narrow, checkable question.
4. Traced the misapplied payments to the underlying bookkeeping error. We obtained the ledger entries from Ivan's own bookkeeper, which showed the two disputed payments had in fact been credited against an unrelated supplier invoice rather than the note, and confirmed the sequence with the supplier's own records. That converted what had looked like a credibility dispute over Ivan's honesty into a documented clerical mistake both sides could accept as fact, which mattered because Dragan no longer had to prove Ivan was lying to prove he was owed the money.
5. Proposed a direct conversation before pursuing further legal steps. Given how personal the breakdown had become, and that Dragan still worked alongside Ivan daily, escalating straight to a formal acceleration demand risked hardening a fixable relationship into an adversarial one neither man could easily walk back from. We recommended a structured settlement discussion, with counsel present on both sides to keep it on the facts, on the view that de-escalating the relationship was a precondition to the financial fix holding rather than a nicety.
6. Negotiated a revised payment schedule reflecting the corrected balance. With the bookkeeping error resolved and the true balance owing established at roughly $855,000, close to Dragan's own figure once the misapplied payments were properly counted back into the balance, we negotiated a revised repayment schedule with stronger security and shorter cure periods for any future default. Anchoring the negotiation in the reconciled figure, rather than either party's opening position, meant the schedule reflected what the records actually showed instead of a split-the-difference compromise.
7. Documented the new terms and Dragan's continued employment separately. To avoid the two issues bleeding into each other again the way they had before, we papered the revised note terms and a separate, clearer employment arrangement for Dragan's ongoing role, each with its own dispute-resolution process. Keeping them as two distinct documents meant a future disagreement about one would not automatically threaten the other, which neither the original note nor Dragan's informal employment understanding had provided for.

The outcome

The ninety-day deadline was met with the protective notice in place, preserving Dragan's right to enforce the note on proper terms. Once the bookkeeping error was traced and both sides accepted the corrected figures, the dispute resolved on Dragan's terms in substance: Ivan agreed the true balance owing was roughly $855,000, close to Dragan's original position once the misapplied payments were properly counted back into the note, and paid it down over a tightened schedule with stronger security than the original note had provided, including a registered charge against Ivan's personal property that had not been part of the original arrangement.

This was a clear win, though it did not come from a courtroom victory — it came from finding a specific, documentable error before the dispute hardened into an adversarial acceleration proceeding that would have cost both men more, financially and personally, than the underlying gap in the numbers ever justified. Had the matter gone to a formal acceleration demand and possible litigation, Dragan would likely have recovered a similar amount eventually, but only after months of proceedings, legal costs on both sides, and very likely the end of Dragan's role in the business well before either man was ready for that.

Dragan and Ivan's working relationship recovered enough for Dragan to continue in his role for another year before moving on to other work by mutual agreement, on terms neither side described as acrimonious. The revised note was paid in full within the following eighteen months, on schedule, with no further defaults. Anahit's business relationship with Ivan also continued afterward, once it was clear the misapplied payments had been an honest bookkeeping error rather than anything either man had done deliberately.

What made the difference, in the end, was treating the deadline and the relationship as two separate problems requiring two different responses — one legal and immediate, protecting Dragan's contractual position without waiting for the numbers to be sorted out, and the other slower and dependent on getting two people who had stopped trusting each other talking again before asking them to sign anything.
