“Reasonable transitional assistance” had no hours, no term and no fee

Anonymised, illustrative composite. A retiring seller agreed to help out after closing — no cap, no clock, no cost. Eight months later he was still fielding client calls, and neither side had ever defined what would end the obligation.

At a glance

  • • Ontario, asset purchase of a bookkeeping and accounting practice at $950,000, sold by a retiring sole practitioner.
  • • The purchase agreement's transition clause read: the seller “shall provide reasonable transitional assistance to the Buyer following Closing, at no additional cost, for such period as may be reasonably necessary to ensure an orderly transition of client relationships” — no hours cap, no defined term, no fee.
  • • Eight months post-closing, the seller was still fielding client calls, training staff and attending client meetings at the buyer's request, unpaid, while the deal's own retirement narrative and non-compete assumed he had stepped back from the industry.
  • • No statute governs an open-ended transition obligation in a business sale; a court asked to enforce it would imply a reasonable scope and a reasonable end date, but “reasonable” costs nothing to write and a great deal to argue about later.
  • • The parties resolved it with a negotiated side letter capping the obligation, rather than test the undefined standard in court — the more common outcome for a dispute like this one.

The situation

A retiring sole practitioner sold his bookkeeping and accounting practice for $950,000. Alongside the ordinary representations and a standard non-compete, the purchase agreement included a single sentence on post-closing help: the seller “shall provide reasonable transitional assistance to the Buyer following Closing, at no additional cost, for such period as may be reasonably necessary to ensure an orderly transition of client relationships”. No hours cap. No defined term. No fee, even after a stated free period.

The problem

Eight months after closing, the seller was still fielding client phone calls, training the buyer's new staff on how specific longstanding clients liked their files handled, and attending client meetings the buyer asked him to join — all unpaid, all justified by the buyer as still “reasonably necessary” under the clause. The seller, who had told his own family and his non-compete counterparties that he was stepping back from the industry, found himself effectively working part-time for a business he no longer owned, with no end date either side had agreed to.

The numbers

By month eight, the seller estimated he had given roughly 140 unpaid hours to the transition — call time, meetings and training — against an original expectation, never written down, of perhaps 20 to 30 hours over the first month or two. Nothing in the $950,000 price or the deal's closing adjustments had accounted for ongoing labour eight months out.

The rule that decided it

No statute governs a transitional-assistance clause in a business sale. The one statute worth checking — because the seller's post-closing work looked, on its face, like an unpaid job — is the Employment Standards Act, 2000, and it does not reach this arrangement either. Section 1(1) defines “employee” to include “a person…who performs work for an employer for wages” and “a person who supplies services to an employer for wages”. Both limbs require wages, and this clause specifically promised none: “at no additional cost” was the parties' own choice, made deliberately, not an omission a court would read past. Without a wage relationship, the Act's minimum standards, and its rule against contracting out of them, never engage.

Where a contract sets an obligation without defining its scope, duration or price, general contract principles — not any specific statute — imply a reasonable standard: a court asked to enforce this clause would read in a reasonable scope of assistance and a reasonable outside date, not an unlimited, indefinite one. That is real protection against an obligation that never ends, but it is not a substitute for a defined term, because “reasonable” is not self-executing — someone still has to litigate what it means, and a $950,000 deal rarely justifies that fight over a few hundred hours of goodwill labour.

The outcome

Rather than test the undefined standard in court, the parties negotiated a short side letter: the transitional assistance obligation was deemed fully discharged as of a stated date, on confirmation that the seller had made himself available for at least a stated minimum number of hours in the aggregate. Both sides gave something up — the buyer lost open-ended access to the seller's help, and the seller accepted a floor that retroactively validated some of what he had already given for free — but the relationship, and the transition itself, ended on agreed terms rather than a dispute.

What it would have cost otherwise

Litigating what “reasonable” meant would have cost both sides more than the value of the disputed hours, with no guarantee either side would consider the result vindicating — a court could as easily find that eight months and 140 hours was still within a reasonable transition for a client-relationship-driven practice as find it was not. Avoiding that uncertainty, not winning it, was what actually resolved the file.

The tell

The tell was in the clause's own language: three unlimited words — “reasonable”, “no additional cost”, “reasonably necessary” — stacked on top of each other with nothing to anchor any of them. It reads as a modest accommodation at signing and functions as an open-ended, unpriced obligation the moment a buyer with an incentive to lean on it starts doing so.

Takeaways

  • • A transition clause with no hours cap, no term and no fee is not a modest accommodation — it is an open-ended obligation bounded only by an implied “reasonable” standard, which is cheap to write and expensive to argue about later.
  • • Price it: even a modest per-diem or monthly rate after a defined free period turns a vague goodwill promise into a governed relationship both sides can plan around.
  • • Set a hard outside date, with an option to extend only by mutual written agreement, rather than leaving the endpoint to “as reasonably necessary”.
  • • This obligation is owed in time, not money — which means a solvent, willing seller can still be squeezed on it long after every dollar term of the deal has been fully paid.
