What does a federal contracting lawyer do?

A federal contracting lawyer helps businesses navigate procurement, contract performance, disputes, and compliance. That can include an award challenge, a teaming agreement, an unpaid subcontract, a government claim, or an audit response.

Shin Law Office assists contractors from offices in Leesburg and Fairfax, Virginia. We begin with the actual agreement, the business’s role, the decision or notice at issue, and the result the client needs to pursue.

Identify the relationship.A government claim and a private prime/subcontractor dispute can follow different routes.

Start with the right legal route

The contract relationship changes the analysis.

A dispute about who should receive an award differs from a dispute about performance after award. A prime contractor’s claim against the government also differs from a subcontractor’s payment claim against the prime.

We identify the party that owes the obligation, the controlling agreement, and the forum before assessing demands, claims, or litigation.

  • Procurement challenge: identify the solicitation or award decision and available protest forum.
  • Government performance dispute: examine the claim, contracting officer process, and potential appeal.
  • Private commercial dispute: examine the teaming agreement, subcontract, or purchase order and governing law.

Sources: GAO: Bid protests · FAR 33.206: Initiating a claim · FAR 44.203: Subcontract consent

Different disputes follow different legal routesA challenge to a solicitation or award calls for a procurement protest analysis. A covered government contract performance dispute may require a contracting officer claim and then a board or court case. A private prime and subcontractor dispute follows the governing agreement and applicable law, with pass-through claims assessed separately.Choose the legal route01SOLICITATION OR AWARDProcurement protestReview standing, forum,grounds, and filing clocks.02GOVERNMENT PERFORMANCEContract claimStart with the contract, notices,and contracting officer process.03PRIME / SUBCONTRACTORPrivate contract disputeReview the subcontract, governinglaw, and any pass-through route.The parties and the issue determine the path.
Federal funding alone does not turn a private subcontract dispute into a direct claim against the government. Identify the agreement, parties, and legal forum first.

Teaming commitments need careful language.

Review workshare, exclusivity, proposal support, negotiation duties, and conditions to a future subcontract. FAR recognition of a teaming arrangement does not itself guarantee that a private promise is enforceable.

Teaming agreement questions

Sources: FAR Subpart 9.6: Team arrangements

Bid protests and award defense

A timely filing and a stay are different questions.

A lost award, unexpected evaluation, or restrictive solicitation term deserves prompt review of the record and the available forum.

Government contract claims

Connect the contract change to the evidence.

Changes, delays, payment disputes, and terminations can raise questions about entitlement, notice, cost support, and the available remedy. An informal request for payment or equitable adjustment may not satisfy the requirements for a claim.

For covered disputes, a written claim is submitted to the contracting officer for a decision. Claims exceeding $100,000 require the certification described in FAR 33.207.

  • Identify the direction or event that caused the claimed impact.
  • Preserve contract notices, modifications, and reservations of rights.
  • Support the amount with reliable cost and performance records.
  • Track submission, the decision, and proof of receipt.

Sources: FAR 33.206: Initiating a claim · FAR 33.207: Claim certification · FAR 33.211: Decisions and appeals

A contracting officer final decision can start alternative appeal periodsFor covered Contract Disputes Act disputes, receipt of the contracting officer final decision generally starts either a 90-day period for an agency board appeal or a 12-month period for an action in the United States Court of Federal Claims. They are alternative forums, not successive extensions. These are not bid protest deadlines.After a final decisionSTART WITH RECEIPTContracting officer’sfinal decision90DAYSAppropriate agencyboard of contractappeals12MONTHSU.S. Court ofFederal ClaimsactionORALTERNATIVE FORUMSCount from receipt; preserve proof.Check jurisdiction and any exception.
The usual covered CDA routes are 90 days to a board or 12 months to the Court of Federal Claims after receipt. Maritime and other jurisdictional issues require review. GAO protests use separate deadlines.

Six years is not the only clock.

FAR 33.206 generally uses six years after accrual for claim submission, subject to exceptions and a valid shorter agreement. Earlier notice provisions and the later appeal period still need separate review.

Sources: FAR 33.206: Initiating a claim · FAR 33.201: Claim accrual

A subcontractor may need a different route.

Subcontractors generally lack direct contractual rights against the government. A pass-through claim may require prime-contractor sponsorship and other conditions. Evaluate the private subcontract claim separately.

Sources: FAR 44.203: Subcontract consent

FAR, DFARS, and contract compliance

Work from the obligations your contract actually creates.

A useful compliance review starts with the solicitation, signed contract, modifications, clause versions, and applicable agency deviations. A general FAR checklist cannot resolve every contract’s requirements.

We help examine contractual obligations, representations, required flow-downs, and supporting records. Where technical or accounting work is needed, legal review should be coordinated with the appropriate professionals.

  • Map the clause to the work, data, systems, and subcontract tier.
  • Separate mandatory flow-downs from negotiated business terms.
  • Assign responsibility for notices, reports, certifications, and records.
  • Review changes before signing or repeating a representation.

Sources: Acquisition.gov: FAR overhaul and deviations · FAR 52.215-2: Audit and records · FAR 52.203-13: Ethics and disclosure

Identify required and negotiated obligations before drafting the subcontractReview the prime contract and applicable clauses. Determine which flow-downs are mandatory under their stated conditions and which additional commercial terms are proposed for negotiation. Write a coherent subcontract, identify responsible owners and records, and assess any lower-tier duties separately.Follow the obligationsPRIME CONTRACTClauses + scope + dataCheck the version and agency direction.REQUIREDFlow-downsApply the clause’strigger, tier, andrequired wording.NEGOTIATEDBusiness termsReview payment,scope, liability,and remedies.A COHERENT SUBCONTRACTAssign responsibility and preserve evidence.Review lower-tier duties separately.
A flow-down review is clause-specific. Cybersecurity, audit, and other requirements have different triggers. Not every prime-contract term applies unchanged to every subcontract.

CMMC and cybersecurity requirements

Review the required CMMC level and assessment type, covered information and systems, current agency direction, and any lower-tier obligations. Avoid assuming every defense subcontract has the same assessment requirement.

Cyber incident reporting under DFARS 252.204-7012 is a separate obligation when applicable. A technical response and a contract-law review may both be needed.

Audits, investigations, and False Claims Act defense

Understand the request before preparing the response.

A records request, questioned cost, fraud allegation, and suspension notice can call for different evidence and procedures. Preserve the full document and identify its deadline.

Prepare for the consultation

Bring the complete record, not just the disputed clause.

Use the checklist that fits the matter. A clear timeline and the full agreement make the first conversation more useful.

The agreements and award record
  • Solicitation, amendments, proposal, award notice, and debriefing exchanges.
  • Signed prime contract, modifications, teaming agreement, and subcontracts.
  • Flow-downs, attachments, incorporated documents, and governing-law provisions.
Notices and the timeline
  • The complete notice, final decision, audit request, or subpoena.
  • Dates and times of receipt, submission, and any confirmed extensions.
  • A short timeline and the business’s immediate objective.
Performance, costs, and payment
  • Invoices, delivery and acceptance evidence, time records, and cost support.
  • Change directions, approvals, cure notices, and disputed deliverables.
  • Communications explaining the problem and the response.
Compliance and company structure
  • Relevant policies, representations, certifications, and prior disclosures.
  • Ownership, control, affiliate, program, and joint venture records when relevant.
  • A description of affected systems or data; arrange a suitable channel before sharing sensitive material.
Preserve originals and use the right channel. Keep records intact, including relevant messages and receipt information. Arrange an appropriate method with counsel before sending classified information, controlled unclassified information, or other protected contract data.

These answers address procurement, contract relationships, and compliance. The actual agreement, facts, forum, and current requirements control the particular matter.

Discuss your question
What does a federal contracting attorney help with?

A federal contracting attorney helps businesses assess procurement challenges, government contract claims, teaming and subcontract disputes, compliance obligations, and agency inquiries. The first step is identifying the contract, the parties, the forum, and any time-sensitive notice.

Sources: GAO: Bid protests · FAR 33.206: Initiating a claim · FAR Subpart 9.6: Team arrangements

Does Shin Law Office work with prime contractors and subcontractors?

Shin Law Office assists prime contractors and subcontractors with contract review, performance disputes, payment issues, and compliance questions. The legal route depends on the business’s role and agreements. Representation in a particular matter follows a conflicts check and an agreed scope of services.

What is a federal bid protest?

A bid protest challenges the terms of a federal solicitation or a proposed or actual contract award. Potential issues include evaluation errors, unequal treatment, or an improper solicitation requirement. Available forums and standing requirements must be assessed before choosing where to file.

Sources: GAO: Bid protests

How long do I have to file a GAO bid protest?

Apparent solicitation defects generally must be protested before bid opening or the initial proposal deadline. Other grounds generally must be filed within 10 days after the protester knew or should have known the basis. Required debriefings and other circumstances can change the analysis. There is no universal 10-days-after-award rule.

Sources: 4 CFR § 21.2: Protest timing

Does a timely GAO protest automatically stop contract performance?

No. Protest timeliness and the conditions for a statutory stay are different. The ordinary post-award rule in FAR 33.104 addresses agency receipt of GAO notice within 10 days after award or 5 days after the date offered for a requested and required debriefing, whichever is later. Applicable debriefing procedures and authorized overrides also require review.

Sources: FAR 33.104: GAO protests

Should I wait for a debriefing before discussing a protest?

No. Request a debriefing within the applicable period and obtain advice about the particular procurement. GAO has a special rule for debriefings that are both requested and required, and enhanced defense debriefing procedures can affect timing. An optional debriefing or an unanswered question does not necessarily delay a deadline.

Sources: 4 CFR § 21.2: Protest timing · FAR 33.104: GAO protests

Can the firm help defend an award that another bidder protests?

Yes. The firm can assess the protest, participation rights, the award record, and response strategy. An awardee should preserve its proposal and communications and follow the agency’s actual performance instructions. An award does not guarantee that a protest will be dismissed or that performance will continue uninterrupted.

Sources: GAO: Bid protests · FAR 33.104: GAO protests

Are teaming agreements enforceable?

Enforceability depends on the agreement and applicable law. Review whether the language creates definite obligations or leaves essential terms for a future subcontract, along with conditions, exclusivity, and remedies. FAR recognition of contractor team arrangements does not itself make every private workshare promise enforceable.

Sources: FAR Subpart 9.6: Team arrangements

What if a prime contractor reduces the workshare promised to a teammate?

Compare the signed teaming agreement, proposal commitments, any awarded subcontract, and the communications about the change. Potential remedies depend on which obligations became binding, applicable law, conditions, and provable loss. A workshare percentage alone does not guarantee a recovery.

Sources: FAR Subpart 9.6: Team arrangements

What can a subcontractor do when the prime does not pay?

Review the subcontract’s payment, acceptance, notice, dispute, and termination provisions. Preserve invoices, work records, change approvals, and payment communications. Counsel can evaluate a demand, negotiation, mediation, arbitration, or litigation as appropriate. The fact that a project is federally funded does not by itself create a direct payment claim against the government.

Sources: FAR 44.203: Subcontract consent

Can a subcontractor bring a Contract Disputes Act claim directly against the government?

Generally, a subcontractor lacks a direct contractual relationship with the government. A government-related subcontractor claim may need sponsorship through the prime under a valid pass-through arrangement, subject to legal requirements and defenses. A private claim against the prime uses a different analysis. Government consent to a subcontract does not itself create a direct contractual relationship.

Sources: FAR 44.203: Subcontract consent

Is a request for equitable adjustment the same as a Contract Disputes Act claim?

Not necessarily. A request for equitable adjustment may seek a negotiated contract adjustment. A claim must satisfy the applicable requirements for submission to the contracting officer for a decision, including certification when required. Its substance and the request for a decision matter more than the document’s title.

Sources: FAR 33.206: Initiating a claim · FAR 33.207: Claim certification

Is there a six-year deadline for government contract claims?

FAR 33.206 generally requires a contractor claim to be submitted in writing within six years after accrual, unless the parties agreed to a shorter period, with other applicable exceptions. Accrual is not necessarily the invoice date or contract closeout. Earlier contract notice requirements and later appeal deadlines still require separate attention.

Sources: FAR 33.206: Initiating a claim · FAR 33.201: Claim accrual

When does a contractor’s monetary claim require certification?

Under FAR 33.207, a contractor must certify a claim exceeding $100,000. The certification addresses good faith, supporting data, the amount believed due, and authority to certify. The claim amount, required language, and signer should be reviewed before submission.

Sources: FAR 33.207: Claim certification

How long do I have to appeal a contracting officer’s final decision?

For covered Contract Disputes Act disputes, the usual alternatives are an appeal to the appropriate agency board within 90 days after receipt or an action in the U.S. Court of Federal Claims within 12 months after receipt. These are alternative forums, not successive extensions. Jurisdiction and exceptions, including maritime matters, require review.

Sources: FAR 33.211: Decisions and appeals

Do all FAR and DFARS clauses apply to every contractor?

No. Applicability depends on the procurement, agency, contract type, clause prescription, incorporated terms, modifications, and any governing deviations or legal requirements. FAR overhaul materials do not mean every existing contract has automatically changed. Review the actual solicitation and contract rather than relying on a generic compliance list.

Sources: Acquisition.gov: FAR overhaul and deviations

What are subcontract flow-down clauses?

Flow-down clauses carry specified prime-contract obligations into lower-tier agreements. Some are required when stated conditions apply; others are negotiated commercial terms. Review each clause’s trigger, tier, wording, and performance context. Simply attaching the entire prime contract can leave important duties and conflicting terms unclear.

Sources: FAR 44.203: Subcontract consent · FAR 52.215-2: Audit and records · DFARS 252.204-7012: Safeguarding and reporting

Does every defense subcontract require the same CMMC assessment?

No. Review the solicitation and contract’s CMMC requirement, assessment type, covered systems and information, applicable flow-downs, and current agency direction. DFARS 252.204-7021 distinguishes levels and assessment types; CUI does not by itself answer every certification question. Legal contract review and technical assessment are separate tasks.

Sources: DFARS 252.204-7021: CMMC requirements

What should a contractor do after a possible cyber incident?

Preserve relevant evidence, involve the appropriate technical response team, and promptly review the contract’s reporting obligations. DFARS 252.204-7012 contains rapid reporting and preservation duties for covered incidents when the clause applies. Other clauses or laws may impose additional duties. A general consultation request does not submit a required incident report.

Sources: DFARS 252.204-7012: Safeguarding and reporting

Does SAM registration establish eligibility for every small-business set-aside?

No. SAM registration, size eligibility, and program certification are different requirements. Review the solicitation’s NAICS code and size standard, ownership and control, affiliates, required certifications, and relevant eligibility dates. Programs such as 8(a), HUBZone, WOSB, and SDVOSB have distinct rules.

Sources: SBA: Contracting requirements and size · SBA: Set-asides and protests

Is an SBA size or status protest the same as a GAO bid protest?

No. A size or status challenge concerns eligibility under applicable SBA rules. A GAO protest generally challenges procurement conduct or solicitation terms. Filing, response, and appeal procedures differ, so do not use a GAO deadline as the deadline for an SBA matter.

Sources: SBA: Set-asides and protests · GAO: Bid protests

Does an SBA mentor-protégé relationship automatically make a joint venture eligible?

No. Mentor-protégé approval, joint venture terms, the protégé’s eligibility, and procurement-specific requirements must be reviewed separately. An affiliation exception is not blanket permission to ignore ownership, performance-of-work, reporting, or other applicable conditions.

Sources: SBA: Mentor-protégé and joint ventures

How should a contractor prepare for a DCAA audit?

Identify the audit’s scope, authority, requested records, and response dates. Organize the relevant contract, accounting support, labor records, policies, and prior correspondence, and preserve the originals. Counsel and accounting professionals can coordinate their respective roles. The applicable audit clause and contract type determine important access and retention obligations.

Sources: FAR 52.215-2: Audit and records

What if the company receives an OIG subpoena or investigative request?

Keep the complete request and proof of receipt, preserve potentially relevant records, and obtain prompt advice about authority, scope, privilege, and the response deadline. Coordinate a truthful, supported response. Do not alter records or assume that an informal extension request has changed the deadline.

Sources: FAR 52.215-2: Audit and records · FAR 52.203-13: Ethics and disclosure

Does every compliance mistake require a mandatory disclosure?

No. Where applicable, FAR 52.203-13 requires timely written disclosure to the agency inspector general, with a copy to the contracting officer, when its credible-evidence trigger for specified criminal violations or civil False Claims Act violations is met. Assess the facts and other obligations. Exceptions to some internal-control requirements do not create a blanket disclosure exemption.

Sources: FAR 52.203-13: Ethics and disclosure

What is the False Claims Act risk for government contractors?

The civil False Claims Act can apply to knowingly false claims, material false records, and other covered conduct involving government funds. Potential exposure includes treble damages and civil penalties; whistleblowers may bring qui tam actions. A contract disagreement or billing error is not automatically an FCA violation. The particular allegation and legal elements matter.

Sources: DOJ: False Claims Act

Are suspension and debarment the same as a False Claims Act judgment?

No. Suspension and debarment concern the government’s protection and a contractor’s present responsibility under separate administrative procedures. They can affect eligibility for federal business without being the same proceeding as an FCA case. The notice, grounds, response process, and corrective measures require their own assessment.

Sources: FAR Subpart 9.4: Suspension and debarment

Which federal contract terms should be reviewed before signing?

Review scope, price and payment, acceptance, changes, notices, required flow-downs, data and intellectual-property rights, confidentiality, insurance, indemnity, liability limits, termination, disputes, and releases. The priorities depend on the business’s role and the actual work. Identify conflicts between the prime contract, subcontract, and attachments.

What should I bring to a federal contracting consultation?

Bring the complete solicitation or contract and amendments, the relevant teaming or subcontract agreements, key correspondence, invoices or cost records, and any notice, decision, subpoena, or protest. Include a short timeline with receipt dates and the outcome the business wants. Arrange a suitable channel before sharing classified information or controlled contract data.
