Key takeaways
  • The survival period for most representations begins running from the closing date, not from whenever you happen to notice a problem.
  • - Read the indemnification section of your purchase agreement in full, not just the price and closing mechanics, before you get busy running the business.
  • Problems tied to a breached representation don't always announce themselves clearly.

Closing day feels like the end of the process. For the representations and warranties in your purchase agreement, it's actually the start of a different clock — the survival period, which sets how long you have to discover a problem and bring a claim before that particular promise stops being enforceable.

Most articles on survival periods explain the concept in the abstract. This one is about what to actually do with that information — from the day you close through to the day the clock runs out.

The Day the Clock Starts: Closing

The survival period for most representations begins running from the closing date, not from whenever you happen to notice a problem. This matters because buyers often don't start paying close attention to post-closing risk until something goes wrong — by which point weeks or months of the survival period may have already passed without anyone tracking it.

What to Do With This Information Right After Closing

Watching for Trouble During the Survival Period

Problems tied to a breached representation don't always announce themselves clearly. Buyers are often better served by paying attention to specific signals rather than waiting for an obvious crisis:

None of these automatically means there's a valid claim — but each is worth reviewing against the specific representations in your agreement before you dismiss it as an ordinary cost of doing business.

When You Spot Something Close to the Deadline

If a potential issue surfaces as a survival period is approaching its end, the practical choice is usually between sending notice now, based on a good-faith estimate, or waiting to fully quantify the loss first. Most purchase agreements only require a reasonable estimate at the notice stage, not a final number — which means waiting to be certain is often the riskier choice. Get legal advice immediately in this situation rather than letting the deadline pass while you're still gathering details.

After the Clock Runs Out: What's Actually Gone, and What Isn't

Once a survival period for a given category of representation expires, a fresh claim based on that specific representation is generally no longer available — even if the underlying facts would otherwise have supported one. This doesn't necessarily eliminate every possible avenue: claims already properly noticed before expiry typically continue toward resolution, and matters that amount to fraud, or that are tied to a covenant rather than a representation, may be treated differently depending on how the agreement is drafted. Don't assume either way without reviewing your specific agreement.

Frequently asked questions

Should I set a calendar reminder the day I close, or wait until something goes wrong?

Set it the day you close. Waiting until a problem surfaces means you're starting from behind, and survival periods don't pause just because you weren't tracking them.

If I suspect a problem but I'm not certain yet, should I send notice anyway?

Generally yes, using a good-faith estimate, rather than waiting for certainty. Most agreements are built around this exact scenario — a timely, imperfect notice preserves your rights far better than a late, fully-researched one.

Does the survival period pause while the seller and I are still talking informally?

Not usually, unless your specific agreement says so. Informal discussions don't typically extend a contractual deadline — formal written notice, delivered as the agreement requires, is what protects your position.

What if the seller becomes hard to reach during the survival period?

This doesn't stop your deadline from running. Follow the agreement's notice requirements exactly as written — proper delivery to the address or method specified usually counts as notice even if the seller doesn't respond.
