1. Betrayal Behind the Name of Family

Twelve-year-old Ji-hoon Park lost both his parents in a sudden accident. All they left behind was a modest apartment and a savings account intended for Ji-hoon's future college tuition. His uncle, Min-su Kim, the only close relative remaining, stepped forward to become Ji-hoon's legal guardian. Ji-hoon leaned on his uncle, hoping for a stable future amid his grief.

However, Min-su's commitment was short-lived. Facing pressure from personal debts after a failed business venture, he withdrew 10 million KRW from Ji-hoon's savings account on May 20, 2017, and used it for his own living expenses and debt repayment. Furthermore, Min-su neglected Ji-hoon's education and welfare. Eventually, upon the petition of Ji-hoon's aunt, Hye-jin Lee, the court replaced Min-su with Hye-jin as the new guardian.

While conducting a thorough audit of Ji-hoon's assets, Hye-jin discovered the missing funds from 2017. Can Hye-jin, acting on behalf of the minor, recover this money from Min-su and hold him legally accountable?

2. The Core Legal Question

The central issue is whether a guardian is liable for not just the principal amount misappropriated, but also the interest accrued since the day of use. Furthermore, we must determine the legal standing of a successor guardian to claim these damages from a predecessor.

3. What Korean Law Says

The Korean Civil Act imposes a strict fiduciary duty on guardians to protect the assets of their wards. The law specifically addresses the scenario where a guardian uses the ward's money for their own benefit:

Civil Act Article 958 (Consumption of Money and Payment of Interest) Paragraph 2If a guardian has consumed a ward's money for his/her own benefit, he/she shall add interest thereto as from the day on which it was consumed, and if there are any damages caused to the ward, he/she shall be liable to compensate for such damages.

Based on this provision, the guardian is responsible for:

  • Full Restitution: Returning the entire principal amount consumed.
  • Mandatory Interest: Paying legal interest calculated from the very day the money was taken.
  • Additional Damages: Compensating for any other losses, such as lost investment opportunities or penalties incurred by the ward.

4. How Korean Courts Approach This

Korean courts view the relationship between a guardian and a ward as one of utmost trust, requiring the 'Duty of Care of a Good Manager.' Any act of disposing of or spending the ward's assets for the guardian's own benefit is treated as a severe breach of duty. Consequently, courts consistently rule in favor of the ward (or their new representative) to ensure that the ward is returned to the financial position they would have been in had the misappropriation not occurred.

5. Applying the Law to Ji-hoon's Case

Applying the Civil Act to Min-su Kim's actions leads to a clear legal conclusion:

  1. The Starting Point for Interest: Min-su cannot simply return the 10 million KRW. He is legally obligated to pay the principal plus interest calculated from May 20, 2017, until the date the debt is fully repaid.
  2. Calculating Damages: If the 10 million KRW was originally in a high-yield savings account or an investment vehicle that would have generated more profit than standard legal interest, Min-su must cover that difference as well.
  3. The Role of the Successor: As the newly appointed guardian, Hye-jin Lee has the legal authority to file a lawsuit for the return of unjust enrichment and damages against Min-su on Ji-hoon's behalf.

6. Conclusion: What Happened, and What Should You Do?

In the end, Hye-jin has a strong legal ground to sue Min-su and recover the 10 million KRW plus years of accumulated interest. The court will likely prioritize the minor's welfare and order Min-su to pay the full amount to restore Ji-hoon's inheritance.

If you find yourself in a similar situation, consider these practical steps:

  • Audit Financial Reports: Guardians are required to report assets to the court regularly. Always cross-reference these reports with actual bank statements.
  • Promptly Petition for Replacement: If you suspect a guardian is mismanaging or stealing funds, petition the Family Court for a change of guardian immediately to prevent further loss.
  • Secure Evidence of Withdrawal: Obtain bank records showing the exact date of unauthorized withdrawals. This date is critical for calculating the interest you are owed.
