When a parent in Korea begins to lose mental capacity, children living overseas often learn that being family is not enough to manage the parent’s affairs. Banks freeze transactions, property cannot be sold, and siblings may disagree. Korea’s adult guardianship system is the legal tool for these situations. This article explains how it works and how a child living abroad can use it.

1. Why Family Members Cannot Simply Step In

Korean law does not give spouses or children automatic authority over an adult’s property, however close the family is. Once a parent can no longer understand what they are signing, several problems tend to appear together.

  • A new power of attorney is not an option. A document signed by someone who lacks capacity is invalid, and Korean banks and notaries are increasingly careful to check capacity.
  • An existing power of attorney is of limited use. Under the Civil Code, an agency relationship does not necessarily end when the principal loses capacity. In practice, however, banks and registry offices often refuse to accept a power of attorney once they learn the principal has dementia.
  • Banks restrict accounts. Withdrawals beyond small amounts, term-deposit cancellations, and changes to account details typically require the account holder or a legally authorized representative.
  • Real estate cannot be sold or leased. Paying for nursing care by selling or renting out the parent’s apartment requires someone with legal authority to sign.

Key takeaway: Once capacity is lost, the court-appointed guardian is usually the only person who can lawfully act for the parent.

2. The Four Types of Guardianship in Korea

Since 2013, Korea has had four types of guardianship. Which one fits depends on the parent’s condition and on what needs to be done.

  • Full guardianship (성년후견): For someone who persistently lacks the capacity to handle their affairs, such as a person with advanced dementia. The guardian has broad authority to represent the person.
  • Limited guardianship (한정후견): For someone whose capacity is insufficient but not absent. The person keeps their capacity in general, but the court specifies acts that require the guardian’s consent.
  • Specific guardianship (특정후견): Temporary support for a particular matter, such as a single property sale or a specific contract. It does not restrict the person’s general capacity and cannot be ordered against their wishes.
  • Voluntary guardianship (임의후견): A guardianship contract made in advance, while the parent still has capacity. It is discussed in Section 6.

For a parent with moderate to advanced dementia, families most often apply for full or limited guardianship. The court decides which type fits based on medical evidence, not the petitioner’s preference.

3. Applying from Overseas: The Procedure

Who may file

The person concerned, their spouse, relatives within the fourth degree, and certain public officials may petition. A child living abroad has standing to petition just as a child living in Korea does. Residence abroad is not a bar.

The process

① Prepare the petition and supporting documents

  • Family relation certificates showing the relationship
  • A medical certificate or diagnosis describing the parent’s condition
  • A list of the parent’s assets and income, and a description of current care arrangements
  • Written opinions or consents from other family members (the court asks for these, and having them significantly speeds up the case)
  • A power of attorney from the overseas child to Korean counsel, signed abroad and apostilled

② File with the Family Court

  • Jurisdiction lies with the Family Court for the parent’s place of residence in Korea.
  • Korean counsel can file and appear on behalf of the overseas child, so the child does not need to travel to Korea for the filing.

③ Court investigation

  • The court generally orders a psychiatric evaluation of the parent, unless the medical evidence makes this clearly unnecessary.
  • The court hears from the parent directly where possible, and a family court investigator may interview the petitioner and other family members.
  • Overseas petitioners can usually take part through counsel. Arrangements for remote interviews depend on the court.

④ Decision and registration

  • The court appoints a guardian and specifies the scope of their authority.
  • The guardianship is recorded in the guardianship registry, and the registry certificate becomes the guardian’s proof of authority with banks and other institutions.

Petition → Medical evaluation and investigation → Appointment → Guardianship registration → Asset management

How long it takes

An uncontested case commonly takes several months. Disputes among siblings, or delays in the medical evaluation, can extend it considerably. If something urgent comes up while the case is pending, such as hospital bills or a lease about to expire, the court can appoint a temporary guardian as a pre-decision measure.

4. Can a Child Living Abroad Serve as Guardian?

Yes, but the court will look closely at practicality. In choosing a guardian, the Korean court gives priority to the parent’s welfare and wishes. It also considers the candidate’s relationship with the parent, conflicts of interest, and whether the candidate can actually perform the role.

A child living abroad can be a strong candidate for managing finances, particularly if they are the most trusted family member. The court may still be concerned about day-to-day care and hospital decisions. Some common structures address this:

  • Co-guardians with divided roles: for example, the overseas child manages property and a sibling in Korea handles personal care and medical matters.
  • A professional guardian: a lawyer, judicial scrivener, or social worker, often appointed when siblings disagree.
  • A guardianship supervisor: appointed alongside a family guardian to oversee the guardian’s conduct.

Key takeaway: Where siblings disagree, the court frequently appoints a neutral professional rather than any of the children. Agreeing on a plan within the family before filing gives the family far more control over the outcome.

5. Managing Property: What a Guardian Can and Cannot Do

Being appointed guardian does not give unrestricted control over the parent’s assets. Korean law and court supervision impose real limits.

Reporting duties

  • Within two months of appointment, the guardian must prepare an inventory of the parent’s property.
  • The court typically requires periodic reports on the parent’s assets, income, and expenses.
  • The guardian must keep the parent’s money strictly separate from their own.

Acts requiring consent or court permission

  • Selling or leasing the parent’s home requires Family Court permission, even under full guardianship.
  • Where a guardianship supervisor has been appointed, major acts such as borrowing, disposing of important property, starting litigation, or dealing with an inheritance require the supervisor’s consent.
  • In practice, many appointment orders list additional acts that need court permission, such as sales above a set value. Read the appointment order carefully before acting.

Conflicts of interest: the inheritance problem

A situation many families face: the father passes away, the mother has dementia, and a child is the mother’s guardian. The child and the mother are both heirs, so the child cannot represent the mother in agreeing how to divide the estate. A special agent must be appointed by the court for that purpose. The court will also generally expect the mother to receive at least her statutory share.

The same issue arises if the guardian wants to buy, rent, or receive gifts of the parent’s property.

Key takeaway: Guardianship is designed to protect the parent, not to make inheritance planning easier for the children. Expect court scrutiny of any transaction that benefits the guardian or other family members.

6. Planning Ahead: Voluntary Guardianship and Trusts

The best time to deal with dementia is before capacity is lost. If a parent is still in the early stages, or currently healthy, two tools are worth considering.

Voluntary guardianship

  • The parent signs a guardianship contract before a notary, choosing the future guardian (for example, the overseas child) and defining that person’s authority.
  • The contract is recorded in the guardianship registry and takes effect when the parent loses capacity and the court appoints a voluntary guardianship supervisor.
  • The parent’s own choice of guardian and scope of authority are respected, which avoids a contested appointment later.

Trusts

  • Korean banks and trust companies offer dementia-preparation trusts and will-substitute trusts. The parent transfers assets to a trustee, which manages them and pays care expenses under the trust terms.
  • Trusts can operate without court involvement, though they come with fees, and the details vary by provider.

Key takeaway: A notarized voluntary guardianship contract, signed while the parent still has capacity, is often the single most effective step an overseas family can take.

7. Conclusion

For children living abroad, a parent’s dementia in Korea brings legal problems on top of an emotional one. Korea’s adult guardianship system lets a child overseas petition the court, take part through counsel, and even serve as guardian. The process does involve medical evaluation, court investigation, and ongoing supervision, and the guardian’s authority over property is deliberately limited.

Families can make the process much smoother by agreeing on a plan among siblings before filing, and by putting voluntary guardianship or a trust in place while the parent can still make decisions.
