Key takeaways
  • Before you can decide anything, you need real information, not just the fact that a claim exists.
  • The purchase price is reduced to reflect the estimated exposure.

Finding out that the business you're about to buy is currently being sued isn't automatically a reason to walk away — but it is a reason to slow down and ask better questions. Ontario buyers deal with pending lawsuits on target businesses more often than you might expect, and most of the time the right response is to assess and manage the exposure, not abandon the deal.

This article picks up where a litigation search leaves off: once you know a lawsuit exists, how do you actually figure out what it means for your purchase, and what should the purchase agreement do about it?

First: Get the Full Picture of the Claim

Before you can decide anything, you need real information, not just the fact that a claim exists. Ask for:

  1. The pleadings themselves — what is actually being alleged, and against whom (the corporation, an individual owner, or both)?
  2. The current status — is it newly filed, actively being litigated, headed to trial, or in settlement talks?
  3. The dollar exposure claimed, and whether it's realistic or inflated
  4. Insurance coverage — is the claim, or a meaningful part of it, covered by an existing policy?
  5. Legal costs incurred so far, and who's been paying them

A one-page summary from the seller is not enough on its own — your lawyer should generally review the actual court documents.

How the Analysis Changes by Deal Structure

StructureEffect of a Pending Lawsuit
Share purchaseThe lawsuit is a liability of the corporation you're acquiring, whatever happens with disclosure and negotiation
Asset purchaseThe lawsuit generally stays with the selling corporation unless it specifically involves an asset you're buying

This is one of the clearest illustrations of why share and asset structures carry materially different risk — the same pending lawsuit can be a central issue in one structure and largely irrelevant in the other.

Common Ways Deals Respond to a Known Lawsuit

Most deals land on some combination of the first four rather than the last one.

Questions to Work Through With Your Lawyer

Frequently asked questions

Does a pending lawsuit always reduce the purchase price?

Not always — sometimes the response is an indemnity or holdback instead of an upfront price cut, especially where the claim's outcome is genuinely uncertain and a fixed discount would be guesswork on both sides.

What if the lawsuit is against an individual owner, not the corporation?

This matters a lot for structuring. In a share deal it may still be relevant if the owner has obligations to indemnify the corporation, but in many cases a personal claim against an owner stays exactly that — personal — and outside the transaction.

Can I require the seller to settle the lawsuit before closing?

You can ask, and some purchase agreements make this a closing condition, but a seller may not control the timeline of litigation, and forcing an unfavourable settlement isn't always realistic. A holdback or indemnity is often more practical than a hard settlement requirement.

How do I know if the claimed exposure is realistic?

This is exactly the kind of judgment call that benefits from a lawyer reviewing the actual pleadings and, where the amount is significant, potentially involving litigation counsel to assess the claim's merits before you finalize deal terms.
