Nolo’s Plain-English Law Dictionary. . 2009.

The buyer will want the seller to make certain assurances ("warranties (warranty)") about the state of the business (e.g., assets in good condition). If the assurance is incorrect and the seller did not disclose it, it may be sued later for breach of the warranty. The seller will therefore be keen to disclose as much as possible beforehand. Disclosures are usually made in a disclosure letter.
This term has a number of potential meanings:
• In the context of acquisitions, the process of the seller making general and specific disclosures against the warranties (warranty) contained in an acquisition agreement. If the seller fails to disclose a relevant matter, in respect of the warranties, it may be sued by the buyer for breach of warranty. The seller usually makes his disclosures in a disclosure letter and attaches relevant documents to that letter to support its disclosures.
• In the context of dispute resolution, stating in a formal list whether a document exists or has existed and whether you are willing to allow your opponent(s) to inspect it.
