FAR 52.233-4—Applicable Law for Breach of Contract Claim.
Plain-English Summary
FAR 52.233-4 is a very short but important contract clause that addresses one specific issue: what law governs a claim that the government or contractor has breached the contract. It states that United States law will apply to resolve any breach-of-contract claim, which helps avoid uncertainty about whether state law, foreign law, or some other body of law might control. In practice, this clause is a choice-of-law provision that supports uniform interpretation of federal procurement contracts and reduces litigation over governing law. It does not itself create a breach remedy, define what counts as a breach, or replace other contract terms, dispute procedures, or statutory remedies; it simply directs that U.S. law governs breach claims. The clause is prescribed by FAR 33.215(b), so contracting officers include it when required by the FAR, and contractors should understand that any breach dispute will be analyzed under U.S. legal principles rather than non-U.S. or state-law alternatives unless another applicable rule specifically provides otherwise.
Key Rules
U.S. law governs breach claims
The clause expressly provides that United States law will apply to resolve any claim that the contract was breached. This is a mandatory choice-of-law direction for breach-of-contract disputes covered by the clause.
Applies only to breach claims
The clause is limited to claims of breach of contract. It does not address every possible dispute under the contract, such as interpretation issues, equitable adjustments, or claims arising under other statutes or clauses unless they are part of a breach analysis.
Does not define breach
The clause does not explain what conduct constitutes a breach or what remedies are available. Those issues are determined by the contract terms, applicable procurement law, and other governing legal authorities.
Inserted when prescribed
The clause is included as directed by FAR 33.215(b). Contracting officers should use it when the prescription applies, rather than treating it as optional boilerplate.
Supports uniform federal treatment
By selecting United States law, the clause promotes consistent treatment of breach claims across federal contracts and reduces uncertainty about conflicting state or foreign legal rules.
Responsibilities
Contracting Officer
Include the clause when required by FAR 33.215(b) and ensure the contract clearly states that U.S. law governs breach-of-contract claims.
Contractor
Understand that any breach claim will be evaluated under United States law and account for that legal framework when negotiating, performing, and disputing the contract.
Agency
Use the clause consistently where prescribed and support contract administration and dispute handling under the governing federal legal framework.
Legal Counsel
Advise on how U.S. law applies to breach allegations, including interaction with other clauses, statutes, and dispute-resolution procedures.
Practical Implications
This clause is mainly about predictability: it removes doubt about whether a breach dispute will be decided under U.S. law.
Contractors should not assume state-law concepts will control simply because the work is performed in a particular state or involves local subcontracting.
The clause is narrow, so parties should not overread it as covering all disputes or as replacing the Contract Disputes Act, other FAR clauses, or specific remedies.
Because it is a choice-of-law clause, it can matter significantly in litigation or claims analysis even though the text is brief.
A common pitfall is assuming the clause changes substantive rights; in reality, it mainly identifies the governing law for breach claims rather than creating new rights or procedures.
