Vietnamese Buyer Fails to Pay: How to File a Lawsuit

Non-payment for delivered goods is one of the most common commercial disputes involving Vietnamese companies. For foreign suppliers and business partners, the situation can be especially frustrating—goods have been shipped, invoices issued, and reminders sent, yet payment is delayed or refused without clear justification.

At this point, many businesses ask the same question:
How do we legally sue a Vietnamese company for unpaid goods, and what should we do first?

This article provides a practical legal roadmap for initiating claims in Vietnam, explains common pitfalls, and highlights how early legal involvement can significantly improve recovery prospects.

Step One: Confirm That a Legal Claim Exists

Before initiating any legal action, it is critical to confirm that the claim is legally valid under Vietnamese law.

Key questions include:

  • Was there a valid contract or purchase order?

  • Were the goods delivered in accordance with agreed terms?

  • Has payment become due under the contract or invoice?

  • Are there any contractual conditions precedent to payment?

Many disputes arise not because goods were unpaid, but because payment conditions were not legally triggered due to missing documents or unclear terms.

Gather and Secure Evidence Immediately

Vietnamese courts and arbitration tribunals rely heavily on documentary evidence.

You should collect and preserve:

  • Contracts, purchase orders, and amendments

  • Invoices and payment requests

  • Delivery documents (B/L, delivery notes, acceptance records)

  • Emails, messages, and written confirmations

  • Any evidence of partial payment or acknowledgment of debt

Weak or inconsistent documentation is one of the main reasons foreign companies lose payment disputes—even when goods were clearly delivered.

Review the Dispute Resolution Clause Carefully

Before filing a lawsuit, the contract must be reviewed to determine:

  • Whether disputes must go to court or arbitration

  • Which court or arbitration center has jurisdiction

  • Whether Vietnamese law applies

Filing in the wrong forum or jurisdiction can delay the case or cause it to be dismissed entirely.

This is a common mistake when foreign companies act without local legal advice.

Consider Demand Letters Before Litigation

In many cases, a formal legal demand letter sent by a Vietnamese law firm can prompt payment or negotiation.

A well-structured demand letter:

  • Sets out the legal basis of the claim

  • Fixes a clear payment deadline

  • Preserves the right to initiate legal proceedings

  • Signals seriousness and legal preparedness

Skipping this step may escalate disputes unnecessarily or weaken later arguments.

When Negotiation Fails, Litigation Becomes Necessary

If demand letters and negotiation do not result in payment, legal action may be unavoidable.

In Vietnam, unpaid goods claims are typically resolved through:

  • Vietnamese courts, or

  • Arbitration (if agreed in the contract)

Each route has different procedures, timelines, and enforcement mechanisms. Choosing the wrong path can significantly affect recovery prospects.

Filing a Lawsuit in Vietnamese Courts: What to Expect

When filing a lawsuit in Vietnam:

  • Claims must be submitted in Vietnamese

  • Documents may need notarization and legalization

  • Strict procedural requirements apply

  • Timelines can be longer than expected

Foreign companies often underestimate the importance of local procedural compliance, leading to delays or dismissal.

Enforcement Is as Important as Winning the Case

Winning a judgment does not automatically mean recovering payment.

Before suing, it is essential to assess:

  • Whether the Vietnamese company has assets

  • Where those assets are located

  • Whether enforcement measures will be effective

A strategic legal approach focuses not only on winning, but on actual recovery.

Common Mistakes Foreign Companies Make

Foreign suppliers often weaken their cases by:

  • Waiting too long before taking action

  • Continuing delivery despite non-payment

  • Accepting vague payment promises

  • Negotiating without legal guidance

  • Filing claims without understanding local procedure

By the time legal action is taken, leverage may already be lost.

Why Early Legal Involvement Matters

The earlier a lawyer is involved, the stronger the position.

Early legal support helps to:

  • Structure communication with the debtor

  • Preserve evidence properly

  • Avoid harmful admissions

  • Select the correct dispute resolution forum

  • Improve chances of recovery

Waiting until frustration peaks often reduces legal options.

Litigation Should Be Strategic, Not Emotional

Non-payment disputes are stressful, but decisions driven by emotion often backfire.

A strategic approach considers:

  • Cost vs recoverable amount

  • Strength of evidence

  • Enforcement feasibility

  • Business impact

Not every unpaid invoice should lead to immediate litigation—but when it does, it must be done correctly.

How Ongoing Legal Consultancy Prevents Payment Disputes

Most payment disputes could be prevented with better legal structure from the beginning.

Ongoing legal consultancy helps businesses by:

  • Drafting clear payment and delivery clauses

  • Aligning contracts with actual trading practice

  • Monitoring payment risk early

  • Advising on legally safe responses to late payment

  • Escalating disputes before leverage is lost

Legal risk is managed before invoices become unpaid claims.

Especially Important for Cross-Border Transactions

Foreign suppliers face additional challenges:

  • Language barriers

  • Different legal cultures

  • Unfamiliar enforcement procedures

  • Difficulty assessing debtor solvency

Without local legal support, these challenges compound quickly.
