Quick answer

Assess the debt, original cheque, dishonour reason and relevant dates before choosing demands, litigation or enforcement. A bounced cheque does not automatically establish a criminal offence; check its elements and applicable law. Recovery depends on enforceable rights and assets, not a guaranteed payment following judgment. Contact our team for a quotation.

In depth

Debt Collection — Bounced Cheques, Enforcement, Seizure: what foreign clients need to know

Recovery that actually produces money starts with what the debtor owns, not with whether a claim exists. A judgment won against a debtor with nothing to seize is spend without return. We therefore check the asset base and the limitation period before deciding between demand letters, a restructuring negotiation, or full litigation.

Limitation is the first thing to check, not the last

Start with enforceability under section 193/12, not interchangeable contract, demand or default-interest dates. Amortised principal instalments and interest arrears have five-year provisions in section 193/33(2) and (1); the ten years in section 193/30 are residual where no specific rule applies. Establish individual due dates and examine acceleration effects before calculating, rather than starting every amount at final maturity.

Before expiry, assess section 193/14 against the debtor's act towards the creditor for the particular claim: written acknowledgement, part-payment, interest or security, with authority and dates. Not every transfer slip renews every balance. A unilateral demand or informal negotiation does not interrupt prescription. Section 193/15 starts a new period when the interruption event ends, not invariably on the filing date. Review section 193/17 before withdrawing or abandoning proceedings, which may be treated as never having interrupted time.

Demanding payment effectively without breaching debt-collection law

Establish the collector and debtor definitions in section3 before treating every obligation as subject to the Debt Collection Act. Sections8–11 regulate recipients, timing and prohibited methods where the Act applies; section12 separately addresses misleading court, official or seizure representations. Threats or public shaming can create liability; they do not automatically erase the debt or decide the creditor's lawsuit. A demand should accurately explain the balance and facts rather than assert seizure powers that do not exist.

Negotiation must distinguish the reduced balance, revised maturity and each person consenting to be bound. The existing guarantor does not automatically follow every debtor term. Section700 addresses extensions of fixed-maturity debt; section691 has specific conditions for post-default debt-reduction agreements. For a consent judgment, check parties, operative scope and enforcement terms rather than assuming it permits execution against an unbound guarantor.

From judgment to money received: the enforcement stage people overlook

Before seeking a writ, separate the command in section272, compliance period in273 and section276 requirements. Check notice or deemed knowledge, expiry and stay or suspension orders; neither finality nor immediate seizure is universal. Identify the obligation and execution method under275, then assess deposits, attachable income, receivables, land or shares against each asset's exemptions.

Build the section274 calendar from the judgment or order for the general ten years. Separate instalment or future obligations starting at enforceability and targets covered by timely officer requests for seizure/attachment or partly undertaken other execution, which can continue to completion for that enforcement. Tracing or a writ does not preserve every new target. Track actual dates and assets rather than starting every balance at finality.

Cost structure: government fees vs professional fees

Item	Official fee	Professional fee	Note
Demand letters and pre-litigation negotiation	Registered-post charges at actual rates	Contact our team for a quotation	Best value where the debtor is contactable and has regular income
Filing a recovery claim in the court of first instance	Filing fees on the claim value, plus service costs by distance	Contact our team for a quotation	Small-claim and consumer-case tracks are shorter and cheaper
Asset tracing and enforcement of the judgment	Replacement Schedule5 distinguishes sale at2% of proceeds, payment of attached money at1% of that money, and inter-party bidding at1% of the highest bid. Do not add all rates; advertising and incidental expenses are separate	Contact our team for a quotation	These costs are often recoverable from the sale proceeds

A trade debt carried over a year with a supplier still trading

Situation: Hypothetical: a seller has purchase orders and delivery records, but the buyer disputes some items and requests deferred payment. Reconcile the balance and due dates before choosing recovery steps.

Assessment points: Assess delivery proof, settlement authority, instalment terms and prescription effects. If cheques are proposed, examine the genuine obligation and applicable legislation; a cheque does not assure payment.

Illustrative example; outcomes depend on the facts and the authority's decision.

A debtor who moved and closed every account

Situation: Hypothetical scenario: the known account is closed, while a land record shows several owners. Check the debtor's entitlement separately from other owners rather than treating the whole plot as debtor-owned.

Assessment points: Review title, the proposed execution method and section323 claims. Distinguish qualifying release from reserved proceeds for registered co-owners under324(2). Do not infer a seizable share or demand payment from a co-owner without an obligation.

Illustrative example; outcomes depend on the facts and the authority's decision.

When to act, and when waiting is fine

The debt is over six months old and the debtor has gone quiet
Check prescription and assets before planning the demand. Sending a letter earlier does not create a preference or payment priority; examine each creditor's security and legal entitlement.
You learn the debtor is moving assets out of their own name
Take advice quickly; provisional protective measures before judgment may still be available
The balance is clearly below the cost of suing
Negotiate, or bundle several debtors into one exercise; a single small suit does not pay for itself
The debtor has entered bankruptcy or rehabilitation
Obtain the order and publication date before choosing a remedy. Distinguish bankruptcy from rehabilitation and secured rights from distribution claims. Check proof-of-debt rights and restrictions on litigation or execution against the actual procedural stage, not a single deadline assumed for every order

Common pitfalls

Treating termination notice as erasing earlier exposure or an instalment request as discharge

Under699 separate transactions before and after creditor receipt and verify the unlimited continuing guarantee. Under698 establish actual extinction; under701 examine a mature payment tender and refusal evidence, not dispatch dates or a below-balance offer alone

A guarantor pays without checking defences or informing the debtor

Assess sections694–696 and debtor-awareness evidence. Duplicate payment in the statutory circumstances directs the restitution claim to the creditor. Under697, quantify damage from creditor-caused impairment of subrogation rather than promising full recourse

Assuming a revised instalment schedule automatically binds the existing guarantor

Distinguish section700 fixed-maturity extensions and consent to that extension from advance consent; the exception is not all companies. Section691 post-default reductions have their own written-notification and reduced-payment rights. Review agreements, dates and receipt records before assigning liability

Claiming face principal and concealed charges without reconciling the actual advance

Reconcile the advance against false statements concealing interest under section4(2) and disproportionate other benefits under4(3); assess the statutory elements, not the fee label alone. Interest enforceability and payment allocation require the prohibition statute and applicable judgments, not the CCC654 ceiling alone

Petitioning solely because an asset search failed without reviewing insolvency and collateral

Apply sections 9–10 to petitioners' debts and evidence, including surrender of security or the shortfall after valuation, not always gross debt. The court assesses receivership and dismissal under section 14. Filing creates no assets and guarantees no distribution

Treating dishonour as a criminal conclusion or citing section 5 as automatic director liability

Assess an enforceable debt, section 4 circumstances, lawful presentment and refusal. Section 5 addresses compoundability; verify each participant and current Gazette status before real-case use

Collecting in ways the debt-collection law forbids, such as calling beyond the permitted frequency or telling third parties

Verify section3 scope before applying section9 hours and contact limits. Log when the demand was communicated; unanswered calls do not license unlimited harassment. The 2024 clause4 exception requires the person's stated work circumstances and failed ordinary-hours attempts before official-holiday 08:00–20:00 contact; it does not permit later calls in every case. Clause3's alternative location is not disclosure authority. Section8 permits conditional location enquiries, not pressure through relatives or colleagues. Separate section11 threats/disclosure from section12 false-authority representations

Treating every trade claim as a two-year debt and negotiating past its deadline

Section193/34(1) covers the specified traders and claims with an exception for the debtor's own business; section193/33(5) gives five years to specified claims outside the two-year rule. A B2B label alone fixes neither period. Check the cause of action, enforceability date and interruption rather than relying on negotiations

Missing execution time by using finality or assuming a writ preserves every target

Section274 generally runs ten years from the judgment or order; instalment/future debts start at enforceability. Timely requested seizure/attachment or partly undertaken other execution can continue for those targets or methods, not every asset. Trace ahead and check the command, stays and suspension rather than making finality universal

Assuming nominee ownership from debtor use or family connection alone

Inspect the register, agreements and acquisition of rights rather than seizing on suspicion. Section323 qualifying release uses60days from seizure. Registered co-owners may reserve proceeds under324(2), not necessarily release the whole asset. Section295 procedural defects use15days from learning the grounds and before execution completion, not the ownership deadline

FAQ

Frequently asked questions

Debt collection via LINE — legal?

LINE does not automatically make collection lawful. Check Debt Collection Act section3 scope, recipient, timing, frequency and content. Do not post balances in a group or pressure the debtor through their workplace. Section8 restricts third-person contact with narrow exceptions, not a right to public shaming. Falling outside this Act does not authorise threats or unlawful disclosure.

How much salary can be garnished?

Identify the payment and employing body first. Section302(3) protects an aggregate THB20,000 monthly, or an officer-determined amount subject to statutory conditions, for employees outside paragraph(2). Government-agency salaries, wages and pensions under paragraph(2) are exempt subject to other laws. No single percentage applies to everyone; provide payslips and the attachment order for assessment.

Bounced cheque — criminal case?

Not in every case. A return slip proves dishonour, not every criminal element. Promptly assess the underlying debt, issuance, bank reason, knowledge dates and alleged offender under the law applicable to the events. Do not automatically use the return date as the starting point for every deadline.

Debtor has no assets?

Review asset-search findings, debt amount and insolvency evidence first. Finding no assets is not automatic entitlement to petition for bankruptcy, and a creditor cannot appoint an official receiver independently. Assess petition conditions, security and negotiation or enforcement options under applicable orders; filing does not guarantee recovery.

Cheque prescription?

Distinguish cheque-instrument claims, the underlying debt and any criminal complaint. Check the party pursued, cheque maturity, bank presentation, knowledge dates and evidence. A single one-year or three-month formula does not cover every route; do not let negotiations put a deadline at risk.

When does the ten-year period start for a judgment payable in instalments?

Section274 paragraph two addresses judgment/order instalments, monthly, annual or future obligations: start when that obligation may be enforced, not every instalment at pronouncement or finality. Read actual maturity and acceleration terms separately from pre-suit loan prescription. A writ or asset search does not replace timely seizure or attachment steps.

Does the Debt Collection Act cover every debt?

Section3 protects natural-person debtors, including natural-person guarantors, and defines covered collectors by specified creditor categories, such as ordinary-business claims, alongside authorised representatives and collection businesses. An occasional loan between friends is not automatically covered; a habitual commercial lender can qualify without being a financial institution. Protection concerning an unlawful debt does not make that debt enforceable, and exclusion from scope is not permission to threaten.

What contact hours and daily frequency apply?

For covered collection, section9 sets Monday–Friday 08:00–20:00 and official holidays 08:00–18:00, including electronic contact. Different hours require the applicable Committee rule, not unilateral choice. Clause4 of the announcement published on 26 November 2024 permits official-holiday contact at 08:00–20:00 only where the person has explained work circumstances preventing ordinary-hours contact and the collector has already tried unsuccessfully during those hours. It is not a blanket extension. Clause3 identifies the debtor's husband's, wife's or spouse's domicile or address as another location; third-person disclosure safeguards still apply. Clause3 of the 2019 announcement limits communicated collection to the debtor or designated recipient to one contact per day. Bank of Thailand guidance distinguishes receiving the demand, including answering and hearing it or opening a LINE message, from unanswered calls or unread messages. This is not one successful payment, nor permission for unlimited harassing attempts. Preserve occupation details, unsuccessful contact evidence, timing and recipient records for counsel to check the rules applicable on the actual date.

May relatives or a workplace be used to pressure payment?

Section8 reserves collection contact for the debtor or their designated person. Other third-person contact is for locating or verifying whereabouts, with identity and purpose disclosure but no debt disclosure. A spouse, ascendant or descendant who asks the reason permits only necessary and appropriate explanation, not demands that every relative pay. Section9's conditional workplace-location rule does not authorise shaming before colleagues. Assess section11 threats and disclosure separately from section12 false authority claims.

Which transactions matter after notice ending a continuing guarantee?

First establish whether section699's unlimited-duration, successive-transaction guarantee applies. Compare creditor receipt of the termination notice with each debtor transaction. Later transactions are excluded under that rule; prior exposure is not erased by the notice. Review remaining balances and defences separately. Dispatch is not proof of receipt. Section698 requires actual extinction of the obligation, not merely a prescription calculation or debtor bankruptcy discharge that ignores Bankruptcy Act78.

How should a claimed refusal of guarantor payment be assessed?

Obtain tender and refusal evidence, not just a discount request. Section701 concerns guarantor payment from maturity and the creditor's refusal. Review the correct amount, timing and readiness under sections207–208. Offering a partial amount or asking to change the terms is not automatic discharge. Preserve financial and communication records for counsel; a one-sided account does not establish the outcome.

What should a guarantor check before paying the creditor?

Review both debtor and guarantor defences under section694 before payment. Section693 provides recourse and subrogation after payment, not assured reimbursement. Section695 limits recourse for an omitted debtor defence, subject to proof of faultless ignorance. Inform the debtor and preserve payment evidence: section696 addresses an uninformed payment followed by a second payment from an unaware debtor, leaving an unjust-enrichment claim against the creditor rather than recourse against the debtor. Lack of notification alone does not establish every element of that outcome.

Can the creditor release security and still demand the full guarantee?

Do not rely on the face balance. Section697 examines creditor conduct impairing subrogation to an existing right, mortgage, pledge or priority given before or when the guarantee was made. The discharge matches the resulting damage, with conduct, causation and amount requiring proof. It is not an automatic full discharge whenever collateral depreciates. Supply security records, release documents and payment history for counsel to assess the claim.

Does extending repayment always preserve the existing guarantee?

For fixed-maturity obligations, section700 discharges a non-consenting guarantor when the creditor agrees to extend the payment time. Advance consent given before the extension is unenforceable, except for a guarantor that is a financial institution or routinely guarantees for remuneration, not every company. The section691 exception concerns an extension in a debt-reduction agreement made after default. Mere delay in collection or any negotiation is not automatically a releasing extension. Examine the terms, dates and transitional law.

What must a guarantor be told about a debt reduction?

Section691 requires written notification within60days of the debt-reduction agreement, distinct from section686's default trigger. Release depends on the debtor paying the reduced debt, or the guarantor paying the remaining reduced amount or the reduced debt as provided, not merely signing a reduction. The guarantor can exercise the payment right within60days after reduced-debt maturity; notification after maturity gives a60day period from the creditor's written-notification date in the statutory text. Preserve notification and receipt evidence for counsel rather than equating those dates. A term imposing greater burdens than paragraph one is void. Do not transfer section686's late-notice consequences to section691.

Does part-payment after expiry restart the remaining balance?

Do not assume so. Section 193/28 bars recovery of any payment on a prescribed claim even if the payer did not know it had expired; this does not automatically restart the original period for the unpaid balance. A written-evidenced acknowledgement of liability or security under its second paragraph creates a claim with two years from acknowledgement or security under section 193/35, subject to section 193/27. That acknowledgement cannot be invoked to the detriment of an existing guarantor. Distinguish pre-expiry acts, post-expiry documents and guarantor rights.

Can a creditor assume discharge after counting three years?

Further checks are required. An individual's ordinary section 81/1 period starts at the bankruptcy judgment, unlike the published receivership date used for proof of debt. A prior judgment less than five years before later receivership leads to a five-year discharge period; dishonest-bankruptcy and public-fraud borrowing grounds involve ten years with different exceptions. Sections 81/2–3 allow judicial suspension of the ordinary period for unjustified failure to assist asset collection, totalling no more than two years, not a creditor's unilateral extension. Suspension does not apply to exception periods (1)–(3). Have counsel examine the orders before selecting a creditor remedy.

How should a creditor preserve rights after receivership?

For repayment from the estate, section 91 generally gives two months from the published absolute-receivership order; even a petitioner must check their own filing. A creditor outside Thailand may be granted up to two further months by the receiver. Distinguish pre-receivership security under section 95, open to inspection, from section 96 shortfall claims. Force majeure may support a section 91/1 court application, not guaranteed permission or recovery of sums already distributed.

Does discharge erase every debt and guarantor obligation?

No. Section 77 retains government/municipal tax or customs debts and the specified fraud-related debts. Section 78 does not release partners, co-obligors, guarantors or guarantor-like persons solely because the debtor is discharged; examine individual defences. Discharge neither proves full payment to creditors nor permits status to be assumed from a rough date calculation.

Does reaching the debt threshold suffice for bankruptcy?

No. Section 9 also requires insolvency and a determinable amount. Debt owed to one or several petitioning creditors must total at least 1 million baht for an individual or 2 million for a juristic person, whether due now or in the future. Secured creditors face section 10 conditions on recourse beyond security and surrender or a valued shortfall meeting the threshold. The court determines the facts and order under section 14; creditors do not appoint the official receiver themselves.

What must be proved beyond a cheque return slip?

Under section 4 of the 1991 Cheque Act, prove an existing enforceable debt, lawful presentation and refusal, plus one of five circumstances: intent not to pay, no funds at issuance, an amount exceeding funds at issuance, withdrawal causing insufficiency, or a dishonest stop-payment instruction. Section 5 makes the offence compoundable; directorship alone is not liability. Assess individual acts and the law's status before proceeding.

Must a holder wait 30 days after notice before complaining?

That is not a general section 4 element. Section 7 concerns termination if the offender pays the holder or bank within 30 days of the drawer receiving written refusal notice, or the obligation ceases to bind before final judgment. Assess receipt and payment separately from complaint deadlines; a demand letter does not automatically extend every time limit.

Can repeal status be established from news alone?

No. Parliamentary material located on 29 October 2026 describes a repeal bill, not verified promulgation. This search does not certify that no later enactment exists. Counsel must check the Royal Gazette and its effect on past events. Unpaid debt alone does not establish all fraud elements.

Can we sue without a written contract?

The debt type matters; a transfer slip is not a universal basis for suit. For loans over THB 2,000, section 653 paragraph one requires written evidence of borrowing signed by the borrower. A full-form agreement is not mandatory, but a transfer record alone does not establish compliance. Electronic records need assessment of content, signatory and statutory conditions. Delivery notes and purchase orders concern their sale obligations, not automatic substitutes for loan evidence.

What evidence should a borrower keep after repayment?

For a loan evidenced in writing, section 653 paragraph two conditions proof of repayment on a writing signed by the lender, return of the loan-evidence document, or cancellation marked on that document. Obtain a lender-signed receipt identifying the debt, amount and date; handle the original appropriately on full repayment. Preserve transfers and conversations as supporting material. A slip alone or oral testimony is not guaranteed sufficient in every dispute; part-payment does not justify treating the whole loan document as discharged.

How much salary can be attached?

Distinguish section302(3) monthly income from government-agency income under(2) and termination sums under(4). The statute protects aggregate monthly income of THB20,000 and gratuity or severance of THB300,000, or an officer-determined amount within statutory conditions. An interested person disputing that determination may petition the court within15days of learning of it. This is neither a30% deduction from all income nor authority for a creditor to order payroll deductions independently.

Does an excessive rate automatically determine the principal balance?

Review money actually advanced, concealed benefits and receipts before fixing a balance. Section654 contains a15% reduction provision, but the prohibition statute and relevant civil judgments must also be considered. Promise neither a full principal recovery nor automatic credit of every interest payment. Section4(2) addresses false loan evidence used to conceal excessive interest, and4(3) clearly disproportionate non-interest benefits. Have counsel establish the statutory elements and payment accounting before demanding or suing for an amount.

What default interest can be claimed?

Section 224 uses the section 7 rate plus 2 percentage points annually. The 2021 text sets a 3% base, yielding 5% while that base applies; it is not a permanent 5% rule for every debt. A royal decree may change the base, and a higher rate needs another lawful ground. No interest on interest during default. Establish the default date separately from the demand-letter date and check the applicable legal period.

Does one missed instalment attract interest on the whole balance?

For monetary instalment obligations, section 224/1 confines default-interest principal to the missed instalment, excluding future principal and accrued interest. A conflicting agreement is void, not automatically the entire contract. A single-payment debt is not necessarily an instalment obligation. An acceleration clause requires counsel to examine notice, effectiveness and the amount actually due; a missed payment alone does not justify charging the whole balance.

Does the 2021 change rewrite all interest on an older contract?

The signing date alone does not decide. The decree took effect on 11 April 2021: its sections 6–7 apply the amended rules to interest and default interest due from commencement without affecting earlier accrual periods. Section 8 applies the instalment-principal rule to instalments due from that date. Split older contracts by payment due dates and accrual periods, and check any rate-changing royal decree effective for the claim.

Can all instalment-loan principal wait ten years?

Ten years is not the single formula. Section 193/33(2) gives five years for capital amortisation instalments and paragraph (1) five years for interest arrears; section 193/30 supplies ten years only without a specific rule. Separate each enforceable instalment under section 193/12 and examine acceleration of unmatured sums. Acceleration does not automatically restart every amount for ten years. Provide the agreement, balance schedule and payment history for counsel's assessment.

Does waiting to send a demand postpone prescription?

Do not treat a chosen dispatch date as the general start. For a claim requiring demand before enforcement, section 193/13 uses the earliest time demand could be made, or the expiry of an applicable period during which payment is not yet required following demand. Check the claim and contractual terms; withholding a letter is not a way to extend time, and a unilateral demand does not itself interrupt prescription.

Are legal costs recoverable from the debtor?

Courts may award costs to the winner under the statutory table, usually below actual professional fees, so budget realistically.

Can a guarantor be required to pay immediately?

First establish guarantor-signed written evidence and the identified obligation under sections 680–681; a name or oral assurance is insufficient for enforcement. Section 681/1 voids joint-debtor terms, except for consenting juristic guarantors who lose sections 688–690 rights. Multiple guarantors under section 682 are not thereby joint debtors with the principal debtor. Section 686 requires written notification within60days of default and bars demand before receipt. Delayed notice releases post-deadline interest, compensation and accessories, not the whole principal. Section 685/1 voids departures from section686. Review execution, default and receipt dates against transitional rules; counsel should assess sections688–690 defences and the balance before selecting the person to pursue.
