What it means
Sale agreements include warranties about the business, such as "there are no disputes", and the seller discloses facts that make warranties untrue, such as an ongoing dispute. The disclosure letter works alongside the share purchase agreement.
A warranty is a contractual statement about the company, for example that there is no current litigation, and if the seller knows of a claim, the disclosure should identify the matter and its scope rather than hope that a buyer discovers it in a document folder. The agreement decides what counts as effective disclosure and what liability remains, so local law and the signed agreement, not a generic glossary rule, decide a particular claim.
General disclosures may cover public records, accounts or an agreed collection of data-room documents, while specific disclosures identify exceptions against particular warranties. Sellers usually prepare the letter with their lawyers and people who know the contracts, employees, tax affairs and disputes, and a useful schedule points to the relevant warranty, explains the facts, and identifies evidence the buyer can inspect.
Do not paste a vague list of document names and assume the buyer can infer the issue. Fair disclosure is often negotiated to mean enough detail for the buyer to identify the nature and scope of a matter.
The UK law-firm discussion by Bird & Bird gives examples where burying information in complex records did not meet the agreed standard, and Norton Rose Fulbright describes general and specific disclosures in share purchases, with the qualification that its article outlines Luxembourg practice. The buyer should treat each disclosure as a decision point, not simply a legal appendix.
A pending lawsuit might lead to a price adjustment, escrow, insurance discussion, a specific indemnity or further diligence. An indemnity is a separate contractual promise about an identified risk, so disclosing the risk does not itself create that promise, and the parties should spell out what happens if the issue worsens between signing and completion.
Timing matters. The seller should start collecting exceptions as the warranties are negotiated, then recheck them before signing and, where required, completion, assigning someone to collect answers from finance, legal, HR and operations.
Use a version-controlled disclosure bundle so both sides know which document set was supplied and when, because late additions can lead to new questions or delay closing and a last-minute upload does not automatically cure an incomplete disclosure. For a simple fictional example, a warranty says all customer contracts are in force without disputes, and Palm Engineering knows that a major customer sent a written notice alleging missed milestones.
It should describe the notice, contract, amount at issue and current response, with the notice attached or referenced clearly, so the buyer can evaluate the commercial exposure, whereas saying only that all contracts are in the data room may not convey that specific risk. There is no universal numerical coverage score for a disclosure letter: counting 80 reviewed warranties out of 100 can measure internal review progress, but it cannot prove that disclosures are fair, and one omitted material dispute could matter more than dozens of routine checks, so replace the tempting percentage with a checklist of each warranty, responsible reviewer, known exception, supporting document and decision by both sides.
In practice
Real-world examples.
Example
A seller identifies a pending customer complaint against the warranty that there are no material disputes and supplies the written notice. The letter names the contract, the date of the notice and the amount claimed. The buyer can then decide how to price the risk.
Example
After a disclosed tax investigation, the buyer requests a separate indemnity that allocates the identified risk. The seller agrees to a cap and a time limit on the indemnity. The disclosure alone would not have given the buyer that protection.
Example
The parties negotiate whether an entire data room is generally disclosed or only a dated, indexed disclosure bundle. They agree on the indexed bundle, which fixes exactly what the buyer was shown. A later upload is treated as new information that needs a separate discussion.
Case study
Seen in the real world.
This illustrative and entirely fictional example follows Palm Engineering, an invented company selling to a larger rival. Palm knew a major customer had alleged a contract breach. Its first draft letter referred only to contracts uploaded in the data room. Counsel asked the team to identify the disputed contract, describe the notice and its potential value, and cross-reference the supporting correspondence.
The buyer reviewed the matter and negotiated a specific allocation of risk in the sale agreement. In this fictional case, both sides had a clearer record of what they had agreed; it does not predict how a real court would decide a claim. Palm's finance team also kept a checklist showing each warranty, who reviewed it and which document supported any exception, and rechecked the list the day before signing.
Watch out
Common mistakes.
- Describing a known issue so vaguely that the buyer cannot assess its nature and scope.
- Uploading documents at the last minute without identifying the relevant exception.
- Assuming a disclosure automatically creates an indemnity or defeats every future claim.
Questions
People also ask.
What is a disclosure letter?
A seller document that identifies exceptions to contractual warranties, usually with general and specific disclosures.
Why does it matter?
It gives the buyer a chance to assess identified risks and may qualify a warranty if it meets the agreed disclosure standard.
Who reviews it?
The buyer and its advisers review it; the seller and advisers prepare it with input from people who know the business.
