Buying a Business With Outstanding Litigation Against It: What Ontario Buyers Should Know

Finding out mid-negotiation that a target business is being sued, or has been threatened with a claim, understandably makes buyers nervous. It shouldn't automatically kill the deal — plenty of otherwise healthy businesses have a dispute in the background — but it changes what due diligence, deal structure, and price need to look like.

This article walks through how litigation exposure should be evaluated and managed when you're buying an Ontario business.

Why Structure Is the First Question

Whether an existing lawsuit becomes your problem depends heavily on whether the deal is a share purchase or an asset purchase.

• In a share purchase, the buyer acquires the corporation itself — and the corporation is the defendant. Any judgment, settlement, or ongoing defence cost attaches to the entity you now own, regardless of when the underlying events occurred.
• In an asset purchase, the buyer generally takes on only the liabilities it specifically agrees to assume. A lawsuit against the selling corporation typically stays with that corporation unless the purchase agreement says otherwise — though buyers should still be cautious about how a lawsuit might affect the value or continuity of the assets and relationships being purchased (a key customer relationship damaged by a dispute, for example, comes along either way).

This is one of the clearest illustrations of why the share-versus-asset choice is not just a tax question — it is a direct liability question, and litigation exposure is often the reason a buyer pushes for an asset structure even when a seller would prefer a share sale.

Step-by-Step: Evaluating Litigation Risk Before You Commit

1. Get full disclosure of every claim, threat, and dispute — not just active lawsuits, but demand letters, regulatory complaints, and disputes that haven't yet been filed. A seller's representations and warranties in the purchase agreement should specifically require this disclosure.
2. Understand what the claim is actually about. A contract dispute over a single invoice is a different risk profile than a product liability claim, an employment dispute, or a class proceeding.
3. Assess insurance coverage. Is the claim covered by the business's existing insurance, and does that coverage survive a change of ownership?
4. Consider the claim's stage. A freshly filed statement of claim with no evidence yet tested carries different risk than a matter close to trial or in active settlement talks.
5. Decide how the risk should be allocated — through structure (asset vs. share), through a specific indemnity, through a holdback, or through a price adjustment.
6. Document it in the agreement, rather than relying on an informal understanding. A disclosure schedule listing every known dispute, paired with specific representations, warranties, and indemnities, is the standard tool.

Deal Tools for Managing Litigation Risk

Specific indemnities

Beyond general representations and warranties, a purchase agreement can include an indemnity aimed specifically at a disclosed lawsuit — allocating responsibility for defence costs and any eventual judgment or settlement to the seller, sometimes without the general caps or time limits that apply to other indemnity claims.

Holdbacks and escrows

A portion of the purchase price can be held back or placed in escrow until a disclosed claim is resolved, giving the buyer a source of recovery without having to chase the seller separately after closing.

Purchase price adjustment

Where the likely exposure can be reasonably estimated, buyer and seller sometimes simply adjust the price rather than build an ongoing indemnity mechanism — trading complexity for certainty.

Excluding the risk entirely (asset deals)

In an asset purchase, the parties can expressly exclude any liability connected to the pending litigation from the assumed liabilities, leaving it with the seller's corporation.

What Undisclosed Litigation Means

If a seller fails to disclose a known claim and it surfaces after closing, the buyer's recourse depends on what the purchase agreement's representations and warranties say — and on proving the seller actually knew about it (see the discussion of "knowledge qualifiers" in representations and warranties generally). This is exactly why thorough, specific disclosure schedules matter more than a general reassurance that "there's nothing going on."
