Clause primer
Sandbagging clause (pro-sandbagging and anti-sandbagging)
The clause states whether a buyer can recover for breach of a representation it knew was inaccurate before closing.
Legal information, not legal advice. What a clause does depends on its exact words, the rest of the agreement and the governing law.
Also called: knowledge savings clause, reliance clause, anti-sandbagging provision. Where you find it: Acquisition agreements, including stock purchase, asset purchase and merger agreements, usually in the indemnification or survival section.
SAMPLE CLAUSE (INVENTED FOR THIS PRIMER)
The rights of each Indemnified Party under Article 9 will not be affected or limited by any investigation conducted by or on behalf of that party, or by any knowledge acquired or capable of being acquired at any time, whether before or after signing or closing, regarding the accuracy of any representation or warranty. The representations and warranties are bargained-for risk allocations, and reliance on them is not a condition to recovery.
How it works
Investigation and knowledge
The first sentence states that the buyer's diligence and knowledge do not reduce its indemnity rights. Including knowledge "capable of being acquired" closes the argument that the buyer should have found the problem.
Timing
Covering knowledge before or after signing or closing addresses issues found during diligence and between signing and closing. Some agreements treat these periods differently.
Risk allocation and reliance
The second sentence treats representations as risk allocations and removes reliance as a requirement. That framing supports recovery under governing laws that would otherwise require reliance.
Anti-sandbagging alternative
An anti-sandbagging clause reverses the result, barring recovery for breaches the buyer knew of before closing. It typically defines knowledge narrowly by named individuals.
Why it is there
The clause decides who bears known risks. A pro-sandbagging clause protects the buyer, which can close on a known issue and still claim. An anti-sandbagging clause protects the seller, which wants known issues raised and priced before closing. Many agreements stay silent, which leaves the result to governing law.
How it works with other clauses
- Representations and warranties: the clause determines whether known inaccuracies still support claims.
- Indemnity caps, baskets and survival: these limit recovery regardless of sandbagging.
- Bring-down and closing conditions: a buyer's knowledge between signing and closing may affect its choice to close.
- Representation and warranty insurance: policies often exclude matters known to the deal team, whatever the agreement says.
Negotiating it
Who it protects: The buyer (pro-sandbagging) or the seller (anti-sandbagging).
If it protects you
- Buyer: keep coverage of knowledge before signing, between signing and closing, and after closing.
- Buyer: keep the risk-allocation and no-reliance language.
- Seller: define knowledge narrowly and require actual knowledge of named people.
If it runs against you
- Buyer standard ask: replace anti-sandbagging with silence or with a pro-sandbagging clause.
- Seller standard ask: anti-sandbagging limited to matters disclosed in writing.
- Fallback: require a buyer to notify the seller before closing of known breaches, or require specific indemnities for known issues.
Escalate before accepting: For a buyer, a broad anti-sandbagging clause that counts constructive knowledge of the whole deal team; for a seller, a pro-sandbagging clause combined with uncapped indemnity.
What AI explanations get wrong
- Assuming silence means sandbagging is allowed. Check: consider governing law on reliance and contract claims.
- Confusing anti-sandbagging with a non-reliance clause. Check: read what knowledge bars and for whom.
- Missing the knowledge definition. Check: confirm whose knowledge counts and whether it is actual or constructive.
- Ignoring insurance exclusions. Check: compare the agreement with the known-matters exclusion in any representation and warranty insurance policy.
Where the law varies
States differ on whether a buyer that knew a representation was false can recover where the agreement is silent, and on the role of reliance in a warranty claim. The governing law therefore matters most when the agreement says nothing.
