Behind every payroll line sits a set of obligations — accrued vacation pay, notice and severance exposure, and sometimes a live grievance or complaint — and selling the business doesn’t make those obligations disappear. It shifts the risk of them onto whoever finds out about them later, usually at the worst possible moment. Disclosing employee liabilities to a buyer honestly and completely is one of the seller’s central obligations in any purchase agreement, and getting it wrong is a leading source of disputes after closing.

This article covers what sellers are typically expected to disclose about their workforce, how that disclosure gets built into the legal documents, and what happens when something surfaces later that wasn’t on the list.

Why This Matters More Than Sellers Expect

Employee-related exposure is easy to underestimate because much of it is invisible on a balance sheet. Accrued vacation pay, an employee close to a notice-triggering milestone, an informal complaint that never became a formal grievance, or a verbal promise about bonus or severance terms — none of these necessarily show up in the financial statements a buyer reviews first. Standard due diligence on a business purchase specifically includes employee records for exactly this reason.

How Disclosure Gets Built Into the Deal

Purchase agreements — whether structured as a share deal or an asset deal — typically include representations and warranties in which the seller states facts about the business, including its workforce, as of closing. Those representations are then qualified by a disclosure schedule: a document listing the specific exceptions, known issues, or ongoing matters that the seller is flagging rather than concealing.

The legal effect is significant. A representation that there are "no outstanding employee claims, except as set out in Schedule 4.12" protects the seller for what’s listed in Schedule 4.12, but exposes the seller to an indemnity claim for anything relevant that should have been listed and wasn’t.

What Sellers Are Typically Asked to Disclose

What Happens When Something Wasn’t Disclosed

Post-closing disputes commonly arise from exactly this kind of gap — a claim or entitlement the buyer discovers after taking over that wasn’t reflected in the disclosure schedule. The purchase agreement’s indemnity provisions are what determine what happens next: typically the buyer notifies the seller of the claim, and depending on the agreement’s terms (caps, thresholds, time limits), the seller may owe compensation for the resulting loss.

This is also why buyers frequently negotiate a holdback — withholding part of the purchase price for a defined period after closing — specifically to have a fund available if an undisclosed employee liability turns up early.

Share Sale vs. Asset Sale: Does the Structure Change What Matters?

In a share sale, the buyer acquires the corporation itself, which means it inherits every employee liability the corporation has — disclosed or not — unless the purchase agreement’s indemnities allocate that risk back to the seller. Full, accurate disclosure is arguably even more critical here, because there is no "leave it behind" option once the shares change hands.

In an asset sale, liabilities the buyer hasn’t expressly agreed to assume generally stay with the selling corporation. But disclosure still matters: a buyer choosing which employees to hire needs an accurate picture of who comes with pending issues, and ESA continuity of service rules mean some obligations can follow specific employees the buyer decides to take on.

Frequently asked questions

What if the seller genuinely didn’t know about a problem?

Representations are usually drafted around actual knowledge for some items and stated as absolute facts for others — the wording matters enormously. A "knowledge qualifier" can limit a seller’s exposure to what it actually knew or reasonably should have known, but it needs to be negotiated deliberately, not assumed.

Do sellers have to disclose informal complaints that were never put in writing?

Generally yes, if they are material. Disclosure obligations are usually framed broadly enough to capture known issues regardless of whether they were formalized — trying to rely on the absence of paperwork is a risky strategy.

Can a buyer walk away if it discovers an undisclosed liability before closing?

Potentially, depending on how the purchase agreement’s conditions and representations are drafted. This is one reason buyers keep asking questions and reviewing documents right up until closing, not just at the letter-of-intent stage.

How long after closing can a buyer bring an indemnity claim for an employee issue?

This depends entirely on what the purchase agreement specifies — most agreements set survival periods and caps for different categories of representations. There is no fixed legal deadline that applies to every deal.
