Debt Non-Existence Lawsuit Lawyer | How to Clear a Debt You Don't Actually Owe

Summary

A debt non-existence lawsuit (채무부존재확인소송) is a civil action filed by a person who has been named as a debtor — often after collection letters, a payment demand, or a threat of compulsory execution — asking the court to declare that all or part of the claimed debt does not exist. It is typically used when a creditor has not yet sued, so the debtor takes the initiative instead of waiting to be sued. Grounds range from simple non-existence (no contract was ever formed) to extinguishment by repayment, extinctive prescription, or setoff.

Debt Non-Existence Lawsuit | When Can You File This Suit?

Courts recognize several distinct grounds for asking for a declaration that a debt does not exist, in whole or in part. Which ground applies changes what evidence you need and how the case will be argued.

Ground 1

The debt never came into existence
You may argue no valid contract, loan, or guarantee was ever formed — for example, a signature was forged, the agreement was void for lack of capacity, or the claimed obligation is based on a transaction you never entered into. This requires the creditor to first prove the underlying obligation, but a proactive suit forces that proof out into the open instead of waiting for a collection lawsuit.

Ground 2

The debt has already been repaid
Where you have already performed the obligation, repayment extinguishes the debt (민법 제460조 이하 변제 관련 조문). Bank transfer records, receipts, or witness accounts of cash payment are central here, and disputes often turn on whether a partial payment was properly credited against principal, interest, or a different debt entirely.

Ground 3

Extinctive prescription (statute of limitations) has run
Civil claims generally extinguish through prescription after set periods — for example many commercial claims after 5 years (상법 제64조) and ordinary civil claims after 10 years (민법 제162조 제1항), with several shorter statutory periods for specific claims. If the creditor's claim has gone unenforced beyond the applicable period without a valid interruption (such as a lawsuit, seizure, or acknowledgment), the debt can be extinguished by prescription.

Ground 4

Setoff or partial extinguishment
If you hold your own claim against the same creditor, you may be able to declare a setoff, extinguishing the debts to the extent they overlap (민법 제492조). This often results in a suit asking the court to confirm the debt does not exist beyond a specific reduced amount, rather than a full non-existence claim.

Ground 5

Void or voidable underlying contract
Where the underlying loan or transaction was procured by fraud, duress, or was contrary to a mandatory statute or public policy, the contract — and any debt arising from it — may be void or subject to rescission (민법 제103조, 제110조). This ground requires detailed factual proof of the circumstances at formation.

What This Suit Cannot Do

A non-existence suit only resolves the specific debt identified in the complaint — it does not erase a poor credit record on its own, and if the creditor later obtains contrary evidence, they may still dispute the judgment through appeal. It also does not stop separate criminal proceedings (e.g., fraud) that may run in parallel to the civil dispute.

Debt Non-Existence Lawsuit | Who Has to Prove What

Unlike a typical lawsuit where the plaintiff must prove the claim they're asserting, a non-existence suit has a distinctive burden-of-proof structure that debtors should understand before filing.

The creditor still has to prove the debt exists

Even though you are the plaintiff who filed the suit, courts generally require the defendant-creditor to prove the existence and amount of the underlying obligation, since that is the substantive fact being disputed. Filing first mainly changes who controls timing and venue, not who bears the underlying burden on existence.

You carry the burden on repayment or extinguishment

If your argument is that a real debt existed but was later extinguished — by repayment, setoff, or prescription — the burden shifts to you to prove that extinguishing event happened. This is why bank records, cash receipts, and any written acknowledgment from the creditor become critical exhibits.

Documentary evidence outweighs testimony

Courts in these cases weigh bank transfer histories, text messages, KakaoTalk chat logs, and contracts far more heavily than oral testimony alone. Before filing, it is worth gathering every relevant transaction record, since gaps in the paper trail are often read against the debtor.

Debt Non-Existence Lawsuit | Choosing Offense Over Defense

Debtors often only think about defending once a collection suit or payment order arrives, but filing a non-existence suit first can change the dynamics of the dispute.

Filing first vs. waiting to be sued

If a creditor is sending demand letters or threatening compulsory execution based on a notarized deed or executory title, filing a non-existence suit lets you set the pace and venue rather than reacting to a suit filed in the creditor's chosen court. It can also head off provisional attachment (가압류) of your assets by putting the dispute before a court early.

Responding to a payment order or execution already in motion

If a payment order (지급명령) has already been served, filing an objection (이의신청) within two weeks converts the matter into ordinary litigation, and a non-existence suit can be pursued within that same proceeding rather than as a separate action. Missing that two-week window can let the payment order become final and enforceable, so timing here matters more than in most civil disputes.

Interim relief while the suit is pending

Where the creditor has already obtained an enforceable title (e.g., a notarized promissory note) and execution is imminent, a debtor may need to seek a suspension of compulsory execution (강제집행정지) alongside the non-existence suit, usually by providing a security deposit or bond. Without this interim step, the main lawsuit's outcome can be overtaken by execution against your assets before judgment.

Debt Non-Existence Lawsuit | From Consultation to Judgment

Case review and evidence collection
We review the creditor's claim, any contracts, transfer records, and communications to identify which ground for non-existence (or extinguishment) best fits your facts.

Filing the complaint
The complaint sets out the specific debt disputed, the amount if partial, and the factual and legal grounds, filed with the court having proper jurisdiction over the creditor or the disputed obligation.

Creditor's response and exchange of evidence
The creditor, as defendant, typically responds with evidence trying to establish the debt's existence and amount; both sides exchange briefs and supporting documents over one or more rounds.

Hearings and, where needed, fact-finding
Contested facts such as disputed signatures, payment history, or the timing of a transaction may require witness examination, document verification requests, or financial institution inquiries.

Judgment and post-judgment steps
The court issues a judgment declaring the debt does or does not exist (or exists in a reduced amount); an unfavorable outcome can be appealed within the statutory period, and a favorable judgment can be used to block or lift attempts at compulsory execution.

Debt Non-Existence Lawsuit | How Fees Are Calculated

Court filing fee (인지액)
Calculated as a percentage of the disputed debt amount stated in the complaint (the amount you claim does not exist), following the Civil Procedure Fee Act (민사소송 등 인지법) fee schedule.

Service and process fees (송달료)
A deposit paid to the court to cover mailing costs for serving documents on the creditor throughout the litigation; unused amounts are typically refunded at the end of the case.

Attorney's retainer fee
Usually set with reference to the amount of the disputed debt and the complexity of the evidentiary issues (e.g., forged signature disputes tend to require more work than a straightforward prescription argument).

Success fee (if agreed)
Where a success fee structure is used, it is typically tied to the amount of debt the court ultimately confirms does not exist, rather than a guaranteed outcome.

Additional costs
Fees for document authentication, appraisal, or financial institution transaction inquiries may be added depending on what evidence the case requires.

※ Costs vary depending on case complexity and specific circumstances; exact fees will be provided during consultation. No specific outcome is guaranteed.

Debt Non-Existence Lawsuit | Self-Check Before You File

1️⃣ Has a Payment Order or Lawsuit Already Been Served?

Frequently Asked Questions

Q. What exactly is a debt non-existence lawsuit?

A. It is a civil action in which you, as the person accused of owing money, ask the court to declare that a specific debt does not exist, in whole or in part. It is typically filed before the creditor sues you, so you control the timing and forum of the dispute.

Q. Do I have to wait until I'm sued to defend myself?

A. No. If a creditor is demanding payment or threatening enforcement without having filed suit yet, you can file this action yourself rather than waiting. This can also help preempt a provisional attachment (가압류) on your assets.

Q. I already received a payment order (지급명령) — what should I do?

A. You generally have two weeks from service to file an objection (이의신청); if you miss that window, the payment order can become final and enforceable like a judgment. Filing a timely objection converts the case into ordinary litigation, where non-existence arguments can then be raised.

Q. Who has to prove the debt exists — me or the creditor?

A. Even though you filed the suit, courts generally still require the creditor, as defendant, to prove the debt actually exists and its amount. If instead you argue the debt was repaid or extinguished by prescription, you bear the burden of proving that extinguishing event.

Q. What counts as good evidence in these cases?

A. Bank transfer records, signed contracts, receipts, and saved chat logs (KakaoTalk, text messages) tend to carry the most weight. Oral testimony alone is usually treated as weaker unless it is corroborated by some documentary record.

Q. Can I dispute only part of the debt, not all of it?

A. Yes. Many of these suits ask the court to confirm the debt does not exist beyond a specific reduced amount — for example, where interest was miscalculated or a setoff applies — rather than denying the entire claim.

Q. What is extinctive prescription and how does it help me?

A. Civil claims are generally extinguished if not enforced within a statutory period — commonly 10 years for ordinary civil claims (민법 제162조 제1항) and 5 years for many commercial claims (상법 제64조), subject to interruption by suit, seizure, or acknowledgment. If the applicable period has run without interruption, you may be able to have the debt declared extinguished.

Q. Will winning this lawsuit fix my credit score automatically?

A. A favorable judgment confirms the legal non-existence of the debt, which you can use to request correction of credit reporting or to resist collection, but the correction itself is usually a separate administrative step with the relevant financial institution or credit bureau.

Q. What if the creditor already has a notarized promissory note against me?

A. A notarized deed can be directly enforced without a separate lawsuit, so if execution is imminent you may need to seek a suspension of compulsory execution (강제집행정지) alongside your non-existence suit, typically by posting a security bond.

Q. Can the creditor still sue me after I file this suit?

A. Generally the creditor's later collection suit over the same debt would be affected by the pending or concluded non-existence action covering the identical claim, but the precise procedural interaction depends on the timing and scope of each case, so this is worth reviewing with counsel.

Q. How long does a debt non-existence lawsuit usually take?

A. Timing varies widely depending on whether the facts are disputed and whether witness examination or financial institution inquiries are needed; straightforward cases can resolve faster than ones involving contested signatures or complex transaction histories.

Q. Is it worth getting a lawyer for a debt dispute over a small amount?

A. Even smaller disputes can involve real evidentiary complexity — such as tracing partial payments or calculating prescription periods — so it is worth having the amount and complexity assessed before deciding whether to proceed alone or with counsel.
