When Construction Contracts Don’t Match Reality in Vietnam

In many construction projects in Vietnam, disputes do not arise because parties intend to breach the contract, but because the contract no longer reflects how the project is actually being executed.

The signed agreement may say one thing, while on-site reality tells a very different story:
different contractors performing the work, informal variations, payment flows outside the contract, or project control exercised by parties not named in the agreement.

When problems surface—delays, defects, payment disputes, or termination—the mismatch between the contract and reality becomes a serious legal risk.

So what should businesses do when their construction contract no longer reflects the real project?

Why This Situation Happens So Often in Vietnam

Construction projects in Vietnam evolve quickly, especially in FDI and EPC projects. Common reasons contracts fall out of sync with reality include:

  • Urgent project timelines leading to shortcuts at signing

  • Reliance on informal instructions and site practices

  • Changes in subcontractors or scope without formal amendments

  • Regulatory or licensing constraints handled “off-contract”

  • Commercial pressure to keep the project moving

While these practices may seem practical at the time, they significantly increase legal exposure if a dispute arises.

Why Contract–Reality Mismatch Is Dangerous

Vietnamese courts and authorities increasingly focus on substance over form.

This means that when a dispute occurs, they will look beyond the written contract and examine:

  • Who actually performed the work

  • Who controlled the site and gave instructions

  • Who received payments and economic benefits

  • How the project was managed in practice

If the contract does not match reality, it may:

  • Be partially unenforceable

  • Be reinterpreted against the parties’ expectations

  • Expose additional parties to liability

In serious cases, courts may disregard the contractual structure entirely.

First Step: Stop Relying on the Contract Alone

A common mistake is assuming that the signed contract automatically protects all parties.

If the project has evolved beyond the contract, continuing to rely on outdated terms is risky. Instead, businesses should acknowledge the gap and address it proactively—before disputes escalate.

Second Step: Identify Where the Contract No Longer Matches Reality

A legal assessment should focus on questions such as:

  • Is the named contractor the actual performer?

  • Are subcontractors operating beyond permitted scope?

  • Have payment methods changed from what the contract provides?

  • Have variations been implemented without formal approval?

  • Has project control shifted to another entity?

Understanding these gaps is essential before deciding how to fix them.

Third Step: Assess Legal and Regulatory Exposure

When contracts do not reflect reality, risks extend beyond civil disputes.

Possible consequences include:

  • Contractual liability for parties who lack real control

  • Joint liability for parties not named in the contract

  • Administrative penalties for illegal subcontracting

  • Project suspension or compliance investigations

Early legal review helps determine which risks are already material and which can still be mitigated.

Fourth Step: Formalize the Actual Project Structure

In many cases, the safest solution is not to terminate the contract, but to bring it back in line with reality.

This may involve:

  • Contract amendments

  • Formal recognition of subcontractors

  • Revised scope of work and responsibilities

  • Updated payment and reporting mechanisms

The goal is to ensure that the written agreement accurately reflects how the project is actually being executed.

Fifth Step: Document Variations and Instructions Properly

Informal site instructions are one of the biggest sources of dispute in Vietnam.

When changes occur:

  • They should be documented in writing

  • Approval authority should be clearly identified

  • Time and cost impact should be recorded

Without documentation, parties often struggle to prove their position in disputes.

Sixth Step: Re-evaluate Termination and Suspension Rights

When the contract no longer reflects reality, termination becomes especially risky.

Improper termination may:

  • Trigger counterclaims

  • Expose the terminating party to damages

  • Lead to regulatory scrutiny

Legal advice is essential before suspending work or terminating a contract that no longer matches project practice.

Why Waiting Until a Dispute Arises Is Costly

Many companies delay action because the project is still moving.

Unfortunately, once a dispute arises:

  • Positions harden

  • Evidence becomes contested

  • Informal practices work against the parties

Correcting structural problems early is far cheaper and more effective than litigating later.

Why One-Time Legal Review Is Not Enough

Many investors rely on legal review only at the signing stage.

However, construction projects are dynamic. Without continuous legal oversight:

  • Contracts quickly become outdated

  • Informal practices take over

  • Legal risk accumulates unnoticed

This is why construction disputes often come as a surprise to management.

How Ongoing Legal Consultancy Prevents These Problems

With ongoing legal consultancy, businesses can:

  • Monitor contract compliance throughout the project

  • Identify deviations early

  • Formalize changes before disputes arise

  • Align commercial decisions with legal requirements

This proactive approach significantly reduces dispute and liability risk.

Especially Important for Foreign Investors and EPC Projects

Foreign investors face additional challenges:

  • Limited familiarity with Vietnamese construction law

  • Dependence on local partners and contractors

  • Language and documentation issues

When contracts and reality diverge, foreign investors often face disproportionate risk.

Continuous legal support helps bridge this gap.
