Signing a personal guarantee is one of the easiest ways for an expat in Thailand to acquire a debt that is not theirs. Banks routinely require directors — including foreign directors — to guarantee company loans; landlords and suppliers ask for guarantors; spouses guarantee each other’s borrowing. A recent Supreme Court decision, Dika No. 7982/2568, shows just how durable that liability is: even when the borrower’s own bankruptcy case was cancelled by the court, the guarantors remained fully on the hook.
The case: four guarantors and a defaulted export loan
A bank extended export credit to a company. Four people guaranteed the debt, and two of them also mortgaged their own property as additional security. The company defaulted, and the bank obtained a bankruptcy order against it. Later, the Central Bankruptcy Court cancelled the bankruptcy of the company (and of one guarantor-mortgagor) under Section 135(3) of the Bankruptcy Act B.E. 2483. The creditor then sued all four guarantors for repayment and enforcement of the mortgages.
The guarantors argued that the cancellation of the debtor’s bankruptcy relieved them too. The Supreme Court disagreed, and its reasoning is a compact lesson in Thai security law:
- Guarantors remain liable. Relief that a debtor obtains through bankruptcy proceedings is personal to the debtor. Under Section 698 of the Civil and Commercial Code (CCC), a guarantor is discharged only when the principal obligation itself is extinguished — by payment, release, or another cause that kills the debt. A bankruptcy discharge does not extinguish the debt; it only shields the debtor personally. So the creditor could still pursue every guarantor.
- A guarantor-mortgagor who was himself released by the bankruptcy court kept a limited shield. One defendant whose own bankruptcy had been cancelled under Section 135(3) was released from personal liability for any shortfall — but his mortgaged property still answered for the debt up to its value.
- The other mortgagor had agreed to broader terms and remained liable for any shortfall after the mortgage sale, as his contract provided.
The Court also applied Sections 95 and 136 of the Bankruptcy Act on the position of secured creditors and the effects of discharge.
How guarantees work under Thai law
A guarantee (ค้ำประกัน) is governed by CCC Sections 680 to 701. The guarantor promises the creditor to perform if the principal debtor defaults. Three features of the regime matter most in practice:
| กฎ | Practical effect |
|---|---|
| CCC s.680 — definition | The guarantee must relate to a valid principal obligation and be evidenced in writing to be enforceable |
| CCC s.686 — notice of default | The creditor must notify the guarantor within 60 days of the debtor’s default before demanding payment from the guarantor |
| CCC s.698 — discharge | The guarantor is released only when the principal debt itself is extinguished — not when the debtor merely becomes personally unreachable (e.g. through bankruptcy relief) |
Since the 2014–2015 amendments to the CCC (Acts No. 20 and 21 amending the Civil and Commercial Code), individual guarantors enjoy meaningful protections: clauses that make an individual guarantor liable “as a joint debtor” are void, the guaranteed obligation must be specifically described (amount, purpose, period), and pre-agreed waivers of the guarantor’s statutory defences are unenforceable. But none of those protections touches the core rule confirmed in Dika 7982/2568: the guarantee survives the debtor’s personal escape routes.
Guarantor vs third-party mortgagor: not the same risk
The decision also draws a clean line between two roles that are often confused when banks paper a loan:
| Guarantor | Third-party mortgagor | |
|---|---|---|
| What is at stake | Entire personal wealth (subject to the contract and CCC limits) | Only the mortgaged property, up to its value |
| Shortfall after sale of security | Liable, if the contract so provides | Not personally liable for the shortfall — unless they agreed otherwise |
| Debtor’s bankruptcy relief | No release (CCC s.698; Dika 7982/2568) | Property still answers for the debt |
In Dika 7982/2568, the difference was decisive: one security provider walked away shielded from any shortfall, while the guarantors — signatories of broader undertakings — remained exposed for the full remaining debt.
What expats should take from this
First, treat a guarantee as a real debt, not a formality. If the borrower fails, Thai courts will enforce the guarantee even where the borrower has been through bankruptcy — debt collection against guarantors is routine and effective.
Second, negotiate the paper. If you must provide security, offering a specific asset as a third-party mortgagor limited to that asset is dramatically safer than an open-ended personal guarantee. If you sign a guarantee, cap the amount, limit the duration, and refuse shortfall clauses where possible. The wording of the loan agreement and the guarantee — not fairness — will decide the outcome.
Third, remember the 60-day notice rule. If a creditor sat on a default for months before contacting you, the CCC s.686 notice requirement (and its consequences for interest and accessory liabilities) is one of the few statutory defences an individual guarantor holds — alongside verifying that the underlying instrument, such as a promissory note, is itself enforceable.
Key statutory provisions
Civil and Commercial Code Sections 680, 686 and 698 (guarantee: form, notice of default, discharge); Bankruptcy Act B.E. 2483 Sections 95, 135(3) and 136 (secured creditors, cancellation of bankruptcy, effects of discharge) — all as applied in Supreme Court decision 7982/2568.
คำถามที่พบบ่อย
If the borrower goes bankrupt in Thailand, is the guarantor released?
No. Bankruptcy relief is personal to the debtor. Under CCC Section 698 and Dika 7982/2568, the guarantor remains liable because the underlying debt still exists.
Can a Thai bank make me liable as a “joint debtor” in a guarantee?
Not if you are an individual. Since the 2014–2015 CCC amendments, clauses making an individual guarantor liable as a joint debtor are void, though the guarantee itself remains valid.
What is the difference between guaranteeing a loan and mortgaging my property for someone else’s loan?
A guarantor’s exposure can reach their entire wealth; a third-party mortgagor generally risks only the mortgaged property, and is not liable for a shortfall after its sale unless they specifically agreed to be.
Does the creditor have to notify me before suing me as guarantor?
Yes. Under CCC Section 686 the creditor must give the guarantor written notice within 60 days of the debtor’s default. Late notice does not void the guarantee but limits accessory liabilities such as accrued interest.
Can foreigners act as guarantors in Thailand?
Yes, and they frequently must — banks commonly require foreign directors to guarantee their Thai company’s borrowing. The obligations are enforceable against them in Thai courts like any other contract.
