What is a disclosure letter?
A disclosure letter, sometimes called a “disclosure schedule,” is a document provided by the seller alongside a sale and purchase agreement (SPA). Its purpose is to disclose exceptions to the warranties given in the SPA.
Warranties are statements by the seller about the business, covering areas such as:
- Financial statements
- Contracts and obligations
- Intellectual property
- Employment matters
- Regulatory compliance
The disclosure letter allows the seller to highlight issues or risks that are already known, limiting their liability for those matters after completion.
Why disclosure letters are important
Disclosure letters are important for several reasons:
- Limiting liability: Warranties in a SPA are legally binding. If a warranty is breached, the buyer may seek damages. A disclosure letter can carve out exceptions, reducing exposure.
- Building trust: Transparency with the buyer fosters confidence and can help negotiations progress smoothly.
- Protecting reputation: By proactively disclosing issues, sellers demonstrate good faith and reduce the risk of disputes.
Without a properly drafted disclosure letter, sellers may face claims for matters the buyer discovers after completion.
Key elements of a disclosure letter
A well-prepared disclosure letter should include:
- Reference to warranties
The letter should clearly reference each warranty in the SPA and specify any exceptions or qualifications. This ensures that disclosures are linked to the relevant contractual obligations.
- Detail of exceptions
Disclosures should be specific and detailed, not general or vague. For example:
- Instead of stating “some contracts may have issues,” specify the exact contracts, the nature of the issue, and any steps taken to resolve it.
Detailed disclosures help prevent misunderstandings and reduce the risk of claims.
- Supporting documentation
Where appropriate, the disclosure letter can include or reference supporting documentation, such as:
- Copies of material contracts
- Regulatory correspondence
- Financial records
- Employment agreements
This provides the buyer with evidence and reassurance about the matters disclosed.
- Structure and organisation
A clear and logical structure makes the letter easier to review and reduces the risk of disputes. Common approaches include:
- Dividing the letter into sections corresponding to the SPA warranties
- Using schedules or appendices for large lists of contracts or assets
- Cross-referencing disclosures to relevant documents
Clarity and organisation improve enforceability and credibility.
Best practices when preparing a disclosure letter
To mitigate risk effectively, sellers should consider the following best practices:
Engage experienced advisers
Legal and financial advisers can help identify potential risks, draft accurate disclosures, and ensure consistency with the SPA. Early involvement prevents last-minute surprises.
Be comprehensive
Even minor issues should be disclosed if they relate to a warranty. Omitting known matters can create liability for the seller. Full disclosure reduces the likelihood of post-completion claims.
Use clear language
Avoid ambiguous terms or vague statements. Disclosures should be precise, factual, and supported by evidence wherever possible.
Update regularly
If circumstances change between signing the SPA and completion, the disclosure letter should be updated accordingly. This keeps information current and protects the seller.
Maintain confidentiality
While disclosure letters are shared with the buyer, sensitive information should be marked as confidential and shared on a need-to-know basis to protect business interests.
Common pitfalls to avoid
Sellers should be aware of common pitfalls that can undermine the effectiveness of a disclosure letter:
- Overly broad statements: General disclaimers like “all known issues are disclosed” are insufficient and may not protect the seller.
- Incomplete references: Failing to link disclosures to specific warranties can create gaps in protection.
- Inconsistent information: Differences between the SPA, disclosure letter, and supporting documents can be used against the seller.
- Late or rushed drafting: Preparing a disclosure letter at the last minute increases the risk of omissions and errors.
Avoiding these pitfalls ensures the letter achieves its intended purpose.
Interaction with warranties and indemnities
The disclosure letter works in tandem with warranties and indemnities in the SPA. Key points include:
- Warranties: Statements about the state of the business. Disclosures qualify these statements where exceptions exist.
- Indemnities: Specific obligations to compensate the buyer for particular risks. A disclosure letter can limit or clarify the scope of indemnities.
A carefully drafted disclosure letter ensures that the seller’s liability is proportionate and manageable.
Legal enforceability
English law recognises the role of disclosure letters in limiting post-completion claims. However, enforceability depends on:
- Accuracy and completeness of disclosures
- Clear linkage to the SPA warranties
- Absence of misrepresentation or fraudulent concealment
Courts are more likely to uphold disclosures that are transparent, specific, and well-documented.
