1. Return of the purchase price | Definition and prescription for claims

A lawsuit for return of the purchase price is a civil lawsuit filed under a sales contract in which property rights are to be transferred and money paid in return, where the other party fails to pay the price or fails to return money already received.
Such a lawsuit goes beyond a simple monetary dispute; because matters such as whether the contract was formed, the content of performance, grounds for rescission, the time of payment, and whether loss occurred must be proven, a systematic legal response is essential.
Extinctive prescription
The extinctive prescription for the right to claim return of the purchase price applies differently depending on the legal character of the transaction, that is, whether it is a commercial act (a business act) or a civil act (non-business).
For ordinary real estate sales, a 10-year extinctive prescription under the Civil Act applies.
By contrast, if the transaction was a sale between both parties dealing in real estate as a business, a 5-year extinctive prescription under the Commercial Act may apply.
In this regard, the starting point of the extinctive prescription is, depending on the circumstances, the date of rescission of the contract, the date of non-payment of the price, or the date of transfer of ownership, and the like.
How to interrupt the prescription
Measure | Description |
Sending a certified content-proof mail | Express the intent to claim through an official document containing the demand for return |
Application for a payment order | A simplified court procedure capable of interrupting the prescription |
Filing a civil lawsuit | The prescription is interrupted as of the date the complaint is filed |
2. Return of the purchase price | How to draft a complaint

To file a lawsuit claiming return of the purchase price, a complaint must be drafted.
In this regard, the complaint should clearly set out not merely a simple monetary claim but the legal relationship of rescission of the contract and return of the price, with supporting evidence attached; this increases the likelihood that it will be accepted by the court.
Required entries
The items that must be included when drafting a complaint are as follows.
Item | Description |
Identification of the parties | Clearly state the name (or trade name) and address of the plaintiff and the defendant |
Identification of the representative | Where there is a statutory representative or a litigation representative, state the name and address |
Contact information | Telephone number, fax number, email address |
Identification of the court | Specify the court with jurisdiction (e.g., ○○ District Court, Civil Division ○, single-judge) |
Date of drafting and signature | The date the complaint is drafted and the plaintiff's name and seal or signature |
Identification of attached documents | Specify the documentary evidence submitted, the receipt for stamp duty and service fees, etc. |
Drafting the purport of the claim
The purport of the claim is the specific content of the claim that the plaintiff seeks to have recognized by judgment.
Example of a purport of claim
2. The costs of the litigation shall be borne by the defendant.
3. Paragraph 1 may be provisionally executed.
Drafting the cause of the claim
The cause of the claim is the part that explains in detail, according to the facts, the legal grounds and background on which the plaintiff bases the claim.
It must be drafted clearly in accordance with the five Ws and one H (when, where, who, what, how, and why).
Example of a cause of claim
2. In accordance with the contract, the plaintiff paid the defendant a down payment of KRW X0,000,000 on XX. XX. 20XX, and also paid an interim payment of KRW X0,000,000 on February 20, 2023.
3. However, the defendant failed to complete the registration of ownership transfer by the agreed deadline of XX. XX. 20XX, and the plaintiff accordingly rescinded the contract as of XX. XX. 20XX.
4. Following the rescission of the contract, the plaintiff requested the defendant to return the purchase price of KRW XX0,000,000 already paid, but the defendant is refusing to return it.
5. The plaintiff therefore brings this action.
Preparing supporting materials
The evidentiary materials supporting the claim for return of the purchase price must be specifically identified.
Each item of evidence may be assigned a number in the form of "Exhibit A No. ○."
Key supporting materials
∙ Supply contract
∙ Written undertaking to pay the price
∙ Transaction ledger
∙ Receipt of delivery
∙ Record of the interim payment by account transfer
∙ Certified content-proof mail
∙ Receipts, etc.
List of attached documents
The documents that must be submitted together with the complaint are as follows.
Document name | Remarks |
1 copy of the corporate registration certificate or resident registration abstract | For verifying the identity of the party |
1 copy of the power of attorney or proof of authority to represent | When a representative is retained |
1 or more copies of the sales contract | Designated as Exhibit A No. 1, etc. |
1 copy each of the receipts for stamp duty and service fees | May be omitted in the case of electronic payment |
1 duplicate copy of the complaint | When submitting on paper, the number of opposing parties + 1 copy |
Because the complaint may be returned if attached documents are missing, it must be carefully checked in advance.
3. Return of the purchase price | Litigation process and finality of judgment

A lawsuit claiming return of the purchase price begins with the filing of a complaint and proceeds through numerous legal steps until the judgment becomes final.
Filing and service of the complaint
A lawsuit claiming return of the purchase price, like an ordinary civil lawsuit, begins with the filing of a complaint.
The court examines the complaint and, if there is no formal defect, serves a duplicate copy of the complaint on the defendant.
If the defendant receives the complaint but makes no response whatsoever, the court may uphold the plaintiff's claim through a "judgment without pleadings."
Submission of the answer and preparatory briefs
The defendant must, from the date of service of the complaint, submit an answer ordinarily within 30 days; in addition, both parties may supplement or organize their arguments through preparatory briefs.
Document name | Description |
Answer | A brief in which the defendant rebuts or partly admits the plaintiff's assertions |
Preparatory brief | A document organizing and summarizing the principal assertions and supporting materials |
List of evidence | A document submitted together with the evidentiary materials, organizing the supporting materials in a table |
Submission of evidence and examination of evidence
The key is to submit evidence proving such matters as whether a sales contract was concluded, the details of payment of the price, and the grounds for return.
The burden of proof rests with the parties, and the following types of evidence are generally used.
Type of evidence | Content and characteristics |
Documentary evidence | The sales contract, records of payment of the price, tax invoices, the content of text messages and emails, etc. |
Examination of witnesses | Examining as witnesses third parties who took part in the transaction, persons present, etc. |
Fact-finding inquiry | The court requests official documents from banks, business counterparts, etc. |
Order to produce documents | Contracts, payment receipts, etc. held by the other party can be secured by court order |
Pleading dates and concentrated evidence-examination dates
As a rule, the trial hears both sides' arguments and examines the evidence through "pleading dates."
Where the issues are complex, witness examination, examination of the parties, and the like are conducted intensively on a concentrated evidence-examination date.
→ Non-attendance may result in losing the case
∙ Where a change of the date is necessary
→ Apply in advance, attaching legitimate grounds and supporting materials
Pronouncement and finality of judgment
Once all examination of evidence and pleadings have concluded, the court sets a date for pronouncement of judgment and renders the judgment.
From the date of pronouncement of judgment, if no appeal is filed within 2 weeks, the judgment becomes final, and after it becomes final, compulsory execution also becomes possible.
▷ Methods of execution: provisional attachment of real estate or automobiles, attachment of claims or wages, etc.

4. Return of the purchase price | How to carry out compulsory execution

Even after prevailing in a lawsuit for return of the purchase price, where the other party does not voluntarily return the price, the creditor can recover the money through compulsory execution proceedings on the basis of a title of execution such as the court's written judgment.
Compulsory execution
Compulsory execution is a procedure whereby, on the basis of a legally recognized document (a title of execution) such as a court's written judgment, a conciliation record, or a notarial deed, state power (the court) intervenes to compulsorily dispose of the debtor's property and pay money to the creditor out of the proceeds.
In other words, it is a means of realizing the right to legally recover money even when the other party does not return the price.
Summary of required documents
Document name | Description |
Authenticated copy of the title of execution | The original or an authenticated copy of a document on which "compulsory execution is possible," such as a court's final judgment, a conciliation record, or a notarial deed |
Execution clause | A certificate by which the court confirms that the written judgment has executory force (an application is required) |
Proof of service | A document proving that the written judgment, etc. was duly delivered to the other party (the debtor) |
Proof of finality | A document proving that the judgment has become final (provided that it may be omitted if the written judgment includes a "declaration of provisional execution") |
The debtor's personal details | Identifiable information such as the debtor's resident registration number and business registration number (in the case of a corporation, a certified copy of the registry is required) |
※ A written judgment with a "declaration of provisional execution" may be subject to compulsory execution even before the judgment becomes final, so execution is possible without proof of finality.
Examples of claims and property subject to execution
∙ Wage claims : Request for wage attachment at the debtor's workplace
∙ Real estate : Provisional attachment of real estate owned by the debtor, or application for auction
∙ Movables such as automobiles : Conversion into cash through public sale after attachment
Summary of the compulsory execution procedure
Prepare the written judgment, execution clause, proof of service, etc.
② Apply for compulsory execution to the court or execution officer
Choose according to the target, such as attachment of deposits or auction of real estate
③ Notification of the execution result and recovery
After disposal of the attached property and distribution → the creditor recovers the money
