In many construction projects in Vietnam—especially those involving foreign investors—it is not uncommon to see contracts that exist only on paper. The contract names one party as the contractor, but in reality, the work is performed by another entity. Payments, instructions, and project management may also differ from what the contract states.

When disputes arise, a critical legal question emerges:

If a construction contract is merely formal, who actually bears legal responsibility?

The answer is often more complex—and riskier—than many investors expect.

What Is a “Formal” Construction Contract?

A construction contract is considered “formal” when:

  • The named contractor does not perform the actual work

  • Another entity carries out construction without being a party to the contract

  • The contract exists mainly to satisfy licensing or regulatory requirements

  • The real relationship between parties differs from contractual wording

This situation often arises when:

  • A licensed Vietnamese company signs the contract, but unlicensed entities execute the work

  • Subcontracting exceeds what is legally or contractually permitted

  • The investor relies on informal arrangements outside the contract

While these structures may seem convenient during project execution, they create significant legal exposure when disputes occur.

Vietnamese Law Focuses on Substance Over Form

Under Vietnamese law, courts and authorities increasingly assess the actual performance and control of the project, not merely what the contract states.

This means:

  • The entity that actually performs the work may be deemed legally responsible

  • The party that exercises control, gives instructions, or receives payment may be treated as the real contractor

  • Formal contracts may be disregarded if they do not reflect reality

In disputes, courts often examine:

  • Who managed the site

  • Who hired workers

  • Who received payments

  • Who benefited economically from the project

A “paper contractor” does not automatically shield other parties from liability.

Liability Risks for the Named Contractor

The company named in the contract—even if it did not perform the work—may still face:

  • Contractual liability for delays or defects

  • Administrative penalties for illegal subcontracting

  • Joint liability for safety or labor violations

In many cases, the named contractor becomes legally exposed without having real control over the project, leading to severe financial and legal consequences.

Liability Risks for the Actual Performer

The entity that actually performs the construction work—despite not being named in the contract—may also face legal exposure.

Potential risks include:

  • Being deemed a de facto contractor

  • Liability for construction defects or accidents

  • Labor and safety violations

  • Tax and licensing penalties

Operating “outside the contract” does not eliminate responsibility—it often increases it.

Risks for the Investor or Project Owner

Investors often assume that responsibility lies solely with the contractor. This assumption is dangerous.

If the investor:

  • Directly instructs the actual performer

  • Pays entities not named in the contract

  • Tolerates or encourages informal arrangements

Then the investor may be considered:

  • A joint employer

  • A party exercising effective control

  • Partially liable for damages or violations

In serious cases, investors may face claims even when they believe they are protected by the contract.

Construction Disputes Reveal Hidden Legal Relationships

Problems with “formal contracts” often surface only when disputes arise, such as:

  • Defective works

  • Delays and liquidated damages

  • Payment disputes

  • Worksite accidents

At that stage, parties realize that:

  • The contract does not match reality

  • Evidence contradicts contractual structure

  • Legal responsibility is unclear

This uncertainty significantly weakens dispute resolution outcomes.

Regulatory and Compliance Consequences

Beyond civil liability, formal-only contracts can trigger:

  • Project suspension by authorities

  • Administrative fines

  • Revocation of construction licenses

  • Delays in project approval or completion

These consequences can affect not only the contractor, but the entire project timeline and investment plan.

Why Courts May Disregard the Contract Entirely

Vietnamese courts may disregard a contract when:

  • It is used to conceal illegal subcontracting

  • It does not reflect actual performance

  • It violates mandatory construction regulations

In such cases, courts may reconstruct the legal relationship based on facts and conduct, not contractual wording.

This creates unpredictable outcomes and increases litigation risk.

Why These Risks Are Often Overlooked

In practice, formal construction contracts exist because:

  • Investors prioritize speed over compliance

  • Legal review is skipped to save costs

  • Parties assume disputes will not arise

  • Enforcement risk is underestimated

Unfortunately, when disputes occur, correcting structural mistakes becomes extremely difficult.

Why One-Time Contract Review Is Not Enough

Many investors believe that reviewing the contract at signing is sufficient.

However, construction projects evolve:

  • Subcontractors change

  • Scope expands

  • Payment structures shift

  • Control dynamics change

Without continuous legal oversight, contracts quickly become disconnected from reality.

How Ongoing Legal Consultancy Prevents Liability Gaps

With ongoing legal consultancy, businesses can:

  • Align contractual structure with actual execution

  • Monitor subcontracting and compliance

  • Adjust contracts as projects evolve

  • Detect legal risk before disputes arise

This approach prevents the formation of “formal-only” contracts that expose all parties to liability.

Especially Critical for Foreign Investors

Foreign investors face additional challenges:

  • Limited familiarity with Vietnamese construction regulations

  • Language barriers

  • Reliance on local partners

Without continuous legal guidance, informal practices may unknowingly violate local law.
