1. Entrustment Contract | Oral Contracts and Delayed Payment Practices Detected: Fair Trade Commission Sanction
An entrustment contract is a form of agreement used when a company assigns specific affairs to an outside specialist firm or individual. As issues such as the failure to prepare written contracts and disputes over payment have recently arisen in subcontracting transactions, the need to understand its legal structure and scope of liability accurately has grown.
Cases in which poor contract management, such as the failure to prepare written contracts or delays in payment, leads to corporate sanctions have recently occurred in succession during subcontracting transactions.
The Fair Trade Commission detected that Hanon Systems, a manufacturer of automotive climate-control products, had failed to properly perform its obligations, including the issuance of written contracts, the notification of inspection results, and the payment of amounts due, in the course of entrusting the production of molds to a partner company, and it imposed a corrective order together with a penalty surcharge of approximately 1.4 billion won.
The investigation found that, from 2020 to 2023, the company had conducted transactions with nine partner companies in a customary oral-contract form, omitting signatures and seals on contracts or failing to issue written contracts.
In addition, numerous cases were confirmed in which the company received deliveries but failed to issue receipts of acceptance or failed to comply with the statutory obligation to notify inspection results in writing within ten days after delivery.
It was further revealed that, in the course of paying subcontract amounts, the company failed to pay the delay interest and the bill-substitute settlement fees that arose from exceeding the 60-day payment deadline.
The Fair Trade Commission stated that, through this measure, it had detected the oral contracts and delayed-payment practices that had customarily occurred in the mold industry, and that it intended to encourage improvements in transaction practices through the use of standard subcontract forms and the specification of conditions for advance and interim payments.
2. Entrustment Contract | Understanding the Diligence of Handling Affairs and the Duty of Care of a Good Manager

One of the most basic forms used when a company assigns work to an outside specialist firm or individual is the entrustment contract.
An entrustment contract applies the provisions on mandate under the Civil Act mutatis mutandis, and it places emphasis on the very ‘process of performing the work diligently’ by the mandatary who has undertaken the work.
This means that, even if the result does not necessarily meet expectations, the mandatary is regarded as having fulfilled its contractual responsibility if it has discharged the duties required of it in the course of performing the work.
A mandatary shall manage the entrusted affairs with the care of a good manager in accordance with the tenor of the mandate.
Here, the ‘care of a good manager’ means the degree of attention objectively required of a person in the relevant occupation or position.
The most important indicator in an entrustment contract is how professionally and diligently the mandatary handled the affairs.
Accordingly, when concluding an entrustment contract, it is above all important to set out in concrete terms the method of performing the work, the reporting system, and the scope of the duty of care.
The Legal Principles of Mandate Under the Civil Act and the Duty of Diligent Performance
In an entrustment contract relationship, the mandatary must employ its knowledge and skills for the benefit of the mandator. In legal terms, this is referred to as the ‘duty of care of a good manager.’
If the mandatary breaches this duty intentionally or negligently and thereby causes loss to the mandator, liability for damages may arise regardless of whether the result was achieved.
The Right to Direct and Supervise the Process of Handling Affairs
Another characteristic of an entrustment contract is that the mandator may exercise a certain degree of direction or supervision over the mandatary's process of handling affairs.
Because the process matters, unlike in a contract for work, the mandator has the authority to receive reports on the progress of the work from time to time and to give appropriate instructions where necessary.
3. Entrustment Contract | The Decisive Difference From a Contract for Work and the Practical Value of Distinguishing Them
A contract for work, which is frequently compared with an entrustment contract, is directed at the ‘completion of a task’.
A contract for work shall take effect when one of the parties agrees to complete a certain task and the other party agrees to pay remuneration for the result of the task.
Under Article 664 of the Civil Act, a contract for work takes effect when one party agrees to complete a certain task and the other party agrees to pay remuneration for the result of the task.
In other words, no matter how diligent the process may have been, the contract is not regarded as having been performed if the promised result is not produced.
Purpose: completion of a tangible or intangible result (website production, construction, development, and the like)
Consideration: payment of remuneration according to the completeness of the result
Liability: warranty liability against defects (where the result is defective, liability for repair or damages arises)
The distinction between the two contracts serves as the standard for determining where liability lies when a dispute arises.
An entrustment contract examines the ‘appropriateness of the handling of affairs,’ whereas a contract for work examines ‘whether the result is defective.’
If software development was entrusted and the program does not run, this becomes a matter of warranty liability against defects under the contract for work, but if legal advice was entrusted and the case was lost, the question becomes whether the attorney fulfilled the duty of care of a good manager.
| Category | Entrustment contract (mandate) | Contract for work |
| Purpose of the contract | Diligence in the process of handling affairs | Completion of the task (the result) |
| Legal basis | Article 681 of the Civil Act | Article 664 of the Civil Act |
| Core duty | Duty of care of a good manager | Duty to deliver a result free of defects |
| Nature of the consideration | Fee for handling affairs | Remuneration for completion of the result |
| Autonomy in performing the work | Strengthened direction and supervision by the mandator | Independent performance of the work by the contractor |
| Liability for defects | Determination of whether performance was diligent | Warranty liability against defects arises |
An entrustment contract commonly involves payment of a monthly fee according to the period of handling affairs.
A contract for work, by contrast, as a rule involves paying amounts in installments according to the progress of the work, or paying the balance after inspecting the final result.
From a company's standpoint, even the payment conditions alone can indicate which nature a given contract is closer to.
4. Entrustment Contract | Legal Risks Arising From Mixed Use in Practice and Points That Warrant Attention

There are many cases in which the title of the contract is drafted as an entrustment contract while the actual operation resembles a contract for work or an employment contract.
Such mixed use heightens legal risk to the greatest degree, particularly in connection with the management of personnel.
If a company uses outside personnel in the form of an entrustment contract while, in substance, the company's own employees give specific work instructions and manage attendance directly, this may develop into an issue of ‘disguised subcontracting’ or ‘illegal dispatch.’
In this case, the personnel concerned may be recognized as workers under the Labor Standards Act, giving rise not only to claims for severance pay and annual-leave allowances but also to administrative sanctions for failure to enroll in the four major insurances.
In addition, there are frequent cases in which a transaction subject to the Fair Transactions in Subcontracting Act is treated as a simple entrustment contract, thereby violating the provisions on payment deadlines or delay interest.
The ‘Substantive Content of the Work’ Matters More Than the Name of the Contract
The court is not bound by whether the contract is named an entrustment contract or a contract for work, but determines the nature of the contract by comprehensively considering the actual manner in which the work is performed and the relationship of direction and command.
Accordingly, from the stage of drafting the contract, one must clarify the scope of the work and design carefully the extent to which independent authority to perform the work will be granted.
Applicable Statutes and Corporate Disadvantages in Cases of Disguised Subcontracting and Illegal Dispatch
Violation of the Act on the Protection, etc. of Dispatched Workers (the Worker Dispatch Act)
Where a company uses workers belonging to an outside firm while, in substance, the principal contractor gives direction and commands directly, this may be found to be illegal dispatch.
In this case, the company may suffer the following disadvantages.
- The obligation of direct employment arises
- Imprisonment with labor for not more than three years or a fine not exceeding 30 million won (Article 43 of the Worker Dispatch Act)
- Inclusion as a subject of a corrective order and supervision by the Ministry of Employment and Labor
Such problems frequently arise in particular on manufacturing production lines or in ongoing operations.
Recognition of Worker Status Under the Labor Standards Act
Even where the parties concluded an entrustment contract, if the structure is in fact one in which the person is subject to the company's direction and supervision, the court may find the person to be a worker regardless of the name of the contract.
In this case, the company may incur the following cost burdens.
- Obligation to pay severance pay
- Obligation to pay annual-leave allowances
- Liability for delayed wages
In addition, if delayed wages arise, the company may become subject to punishment as follows.
- Imprisonment with labor for not more than three years or a fine not exceeding 30 million won (Article 109 of the Labor Standards Act)
Administrative Sanctions for Failure to Enroll in the Four Major Insurances
Where the person is found to be a worker, the company also incurs the obligation to enroll in the four major insurances.
If the failure to enroll is confirmed, disadvantages such as the retroactive imposition of insurance premiums and the imposition of additional charges may arise.
Possibility of Violating the Fair Transactions in Subcontracting Act
Where a transaction is treated as a simple entrustment contract even though it in substance constitutes a subcontracting transaction, an issue of violating the Fair Transactions in Subcontracting Act may also arise.
Representative cases of violation are as follows.
- Failure to prepare a written contract
- Failure to notify inspection results
- Delay in payment
- Failure to pay delay interest
In this case, the Fair Trade Commission may impose sanctions such as a corrective order and a penalty surcharge.
In fact, such cases are frequently detected in mold production and manufacturing partner transactions.
5. Entrustment Contract | A Checklist of Key Risks That Companies Tend to Overlook
If these risks are left unaddressed, they may operate very unfavorably for the company in a future investigation or lawsuit by the Fair Trade Commission or the Ministry of Employment and Labor.
In particular, when carrying out a new project in cooperation with an outside party, one must first define whether the essence of the work is ‘process’ or ‘result’ and then insert the contract clauses that match it.
A company needs a strategy of blocking risks in advance through careful review by a corporate attorney from before the contract is concluded.
Why Daeryun
In the case of an entrustment contract, legal stability can be secured by delimiting the scope of the duty of care of a good manager, and in the case of a contract for work, by precisely setting the inspection criteria and the period of warranty liability against defects.
Because each company faces different circumstances and the work it seeks to outsource has different characteristics, using a uniform template is risky.
One should comprehensively consider the degree of direction and supervision between the parties, the party that provides the equipment and materials, and the party to which gains and losses are attributed, and then design the contract structure that is most advantageous and safe for one's company.
If a dispute over matters such as neglect of work or non-payment in connection with an entrustment contract has already begun, evidence should be secured promptly and the legal position analyzed.
Reports, communication records, and other materials that can prove whether the counterparty breached its obligations should be organized, and legal procedures should be followed, in order to prevent further harm.
