What Is Indemnification?

The Sibyl Un-Glossary · What it actually means

Indemnification

Indemnification is a contractual promise to compensate another party for specified losses when defined risks or breaches occur.

The Sibyl Un-Glossary starts with the definition, then goes beyond it to where founders misinterpret the term.

Indemnification is one of those deal terms that sounds more limited than it is. Founders often hear “cap” and think maximum exposure, or hear “indemnity” and imagine a lawsuit from a customer, employee, or regulator. Both assumptions can make the risk allocation in a financing or acquisition look much safer than it actually is.

The Cap Is Not Always the Ceiling

“If the indemnification cap is $1 million, I cannot possibly owe more than $1 million.”

That is only true if the cap applies to every type of indemnification claim. It often does not. Agreements commonly set a general cap for breaches of ordinary representations and warranties, then carve certain matters out of that cap. Fundamental representations, such as authority, capitalization, or ownership of shares, may be subject to a higher cap. Tax matters, specific known liabilities, covenant breaches, or fraud may also sit under separate rules. So the number labeled as the indemnification cap may really be the cap for one category of claim, not a universal ceiling on liability. You have to read the cap together with its exceptions. Recent M&A deal data illustrates the point. In WilmerHale’s 2026 report, every reviewed 2025 deal in which representations and warranties survived closing had exceptions to its indemnification limits.

Imagine a company is sold for $20 million. The purchase agreement caps ordinary representation and warranty claims at $2 million. After closing, the buyer discovers two problems. First, a customer contract was inaccurately described, causing a $700,000 loss. Second, the company owed $3 million in taxes that were allocated to the sellers under a separate tax indemnity outside the general cap. The $700,000 claim counts toward the $2 million cap. The $3 million tax claim does not. The sellers could therefore face $3.7 million of indemnification claims even though the headline cap is only $2 million.

Indemnification Is Not Only About Third Party Lawsuits

“No one has sued the buyer, so there cannot be an indemnification claim.”

Indemnification provisions can cover third party claims, but they can also cover direct losses suffered by one contracting party because the other breached an agreed representation, warranty, covenant, or specific obligation. A third party claim might arise when a former employee sues the acquired company or a regulator imposes a penalty. A direct claim is different. The buyer itself says, in effect, “You promised this fact was true. It was not, and that caused us a loss.” No outside claimant is required. The agreement determines which losses qualify and what procedures apply. Acquisition agreements commonly include breaches of representations, warranties, and covenants among the events that can generate indemnification obligations, separately from the procedures used when an actual third party claim arises.

Suppose a buyer pays $12 million for a software company. The seller represents that all material customer contracts listed in the disclosure schedule are valid and in force. Two months after closing, the buyer discovers that a contract represented as worth $1 million a year had actually been terminated before signing. No customer sues. No regulator appears. But if the inaccurate representation falls within the indemnification provisions and the buyer can establish a covered $600,000 loss, the buyer may bring a direct indemnification claim for that amount. The absence of a lawsuit does not eliminate the contractual claim.

Why does indemnification matter to early stage founders?

Early stage founders tend to spend much more time negotiating valuation than indemnification. That makes sense during a financing, when dilution is immediate and indemnification can feel remote. But the legal promises made in investment documents can still matter. If the company or, in some jurisdictions and deal structures, the founders themselves give indemnities, those provisions determine who bears the cost when certain statements turn out to be wrong or specified liabilities arise.

The issue becomes even more important in an acquisition. The headline purchase price tells you what the buyer has agreed to pay. Indemnification helps determine how much of that value may later move back toward the buyer if agreed risks materialize. A $20 million sale with tightly limited seller liability is economically different from a $20 million sale where major claims sit outside the general cap.

This is why founders should read indemnification together with the representations, warranties, covenants, baskets, caps, survival periods, exclusions, and special indemnities. None of those provisions tells the whole story alone. The real question is not simply, “What is the cap?” It is, “What can trigger a payment, how much can be claimed, for how long, and from whom?”

How wrong is too wrong?

Thinking that a cap is an absolute ceiling is a serious mistake because it can cause a founder to misunderstand the maximum downside of a transaction. The correction is straightforward. Whenever you see a cap, immediately look for the language that tells you what the cap applies to, then look for every exception. A cap with broad carveouts is not the same protection as a cap that genuinely limits nearly all contractual claims.

Thinking indemnification requires a third party lawsuit is also materially wrong, but easier to catch once you understand the architecture of the agreement. Look at the events that trigger indemnification. If breaches of representations, warranties, or covenants are listed, the counterparty may have a claim even when nobody outside the transaction has complained.

The larger lesson is that indemnification is a risk allocation system, not a single clause. The label matters less than the combination of triggers, limits, exceptions, procedures, and remedies. If you understand only the headline cap or only the third party claim mechanics, you do not yet understand your indemnification exposure.
