Change of Custody Lawyer
Change of Custody Lawyer | Grounds, Evidence, and How the Court Decides
A change of custody (친권자변경) case asks the family court to replace the parent currently designated to exercise parental rights and/or actual custody, usually because that parent is failing to properly raise the child or because circumstances have changed since the divorce. Courts do not treat this as reopening old disputes between the parents; the sole standard is the child's welfare (민법 제837조, 제843조, 제909조 제6항). Because the current custodian will resist, these cases typically hinge on documented evidence of neglect, instability, or the child's own wishes rather than on the petitioning parent's grievances against their ex-spouse.

Change of Custody | When Can Custody Be Changed?
A relative of the child within the fourth degree of kinship, such as a parent, can petition the family court to change the person exercising parental rights (Civil Act Article 909(6)), and a parent, the child or a prosecutor can ask the court to change the person with actual custody (Civil Act Article 837(5)). The court examines whether the current arrangement continues to serve the child's welfare (민법 제909조 제6항, 제837조 제5항).
If the custodial parent is not providing adequate food, education, medical care, or supervision, this can support a change. Courts look for a pattern rather than an isolated incident — repeated absence, leaving the child with relatives long-term without arrangement, or failure to enroll the child in school are commonly cited examples.
Physical, emotional, or sexual abuse, or exposure to domestic violence or substance abuse in the household, is treated as a serious and often decisive factor. Police reports, hospital records, or child protection agency (아동보호전문기관) findings carry significant weight.
Remarriage itself is not automatically grounds for a change, but if it results in an unstable environment, conflict with a stepparent, or reduced attention to the child, it may be considered alongside other factors (민법 제837조 제5항).
For children old enough to express a reasoned preference, courts frequently have a family court investigator interview the child. A clearly and consistently stated wish to live with the other parent, when the child appears capable of independent judgment, is given meaningful weight.
A custodial parent who systematically blocks the other parent's visitation rights (면접교섭권) or coaches the child against the other parent can face a custody change petition, since this behavior itself may be found contrary to the child's welfare.
What courts do not consider decisive
Financial superiority alone is not a sufficient ground — Korean courts do not simply award custody to the wealthier parent. Similarly, fault in the divorce (e.g., who caused the breakdown of the marriage) is largely irrelevant to a later custody change; the focus stays strictly on the child's present and future welfare, not on relitigating the divorce.
Change of Custody | How Courts Assess the Child's Welfare
'Best interests of the child' is not a slogan in these cases — it is the single legal standard the court applies, and it is investigated concretely through home visits, interviews, and expert input.
The family court investigation officer's role
In most custody-change cases, the court assigns a family court investigation officer (가사조사관) to visit each parent's home, interview the parents and, where appropriate, the child, and submit a report. This report is not binding on the judge, but in practice it heavily influences the outcome, so how a parent presents during this investigation matters enormously.
Age and maturity of the child
For children roughly age 13 and older, courts generally give substantial weight to the child's stated preference, assuming no signs of coaching. For younger children, the court relies more on objective indicators — school attendance, health records, and the stability of daily routine.
Continuity vs. change
Korean courts are generally cautious about disrupting a child's established environment (school, friends, primary caregiver) unless the current arrangement is demonstrably harmful. A petitioner who is simply a 'better' parent on paper, without evidence the current arrangement is harming the child, faces an uphill argument.
Change of Custody | Building the Evidentiary Record
Because the current custodian will almost always contest the petition, outcomes are driven by documentation collected over time, not by allegations made at the hearing.
School and medical records
Attendance logs, teacher statements, unexplained absences, and pediatric or dental records showing neglected care are among the most persuasive documentary evidence, because they are created by neutral third parties rather than by either parent.
Communication logs and witness statements
Text messages, KakaoTalk chat logs, and statements from teachers, relatives, or neighbors who have directly observed the child's living conditions can corroborate claims that are otherwise difficult to prove. Courts weigh firsthand, dated evidence far more than secondhand accounts.
Prior violations of the custody or visitation order
If the current custodian has previously violated visitation arrangements or ignored mediation agreements, a documented history of noncompliance (dates, correspondence, mediation records) can support the argument that the current arrangement is not functioning.
Change of Custody | Custody Change vs. Related but Different Claims
Petitioners sometimes conflate custody change with other, related family court procedures. Distinguishing them early avoids wasted motions.
Custody change vs. enforcement of visitation rights
If the real problem is that visitation is being blocked but the child's overall welfare is otherwise fine, the more direct remedy may be a performance order for visitation (Family Litigation Act Article 64), not a full custody change — the two can be pursued together, but they are legally distinct claims.
Change of the 'person exercising parental rights' vs. 'person with actual custody'
Korean law separates 친권자 (the person with parental rights, e.g., legal representation, property management) from 양육자 (the person with day-to-day custody). A petition can seek to change one, both, or neither together, and the appropriate scope depends on which specific problem is being addressed (민법 제837조, 제909조).
Change of Custody | From Consultation to Court Decision
We review the divorce judgment or settlement, the current custody terms, and the specific facts you believe justify a change, and assess whether the available evidence meets the threshold courts look for.
Before filing, we help identify and organize records — school, medical, communication logs, and witness statements — since a petition filed without a documented factual basis is unlikely to succeed regardless of how serious the underlying situation feels.
Custody change cases are generally filed as a family court adjustment (조정) matter first; if mediation fails or is deemed inappropriate, the case proceeds to a litigation (심판) track (가사소송법 제2조).
The court typically orders a home visit and interview process through a family court investigation officer, and may separately interview the child depending on age and circumstances.
The judge reviews the investigation report, evidence, and any child interview results before issuing a ruling. Either party can appeal the decision to a higher court within the statutory period if they disagree with the outcome.
Change of Custody | How Fees Are Structured
Set based on whether the case is expected to proceed through mediation only or requires a full contested litigation track, and on the complexity of the evidence that needs to be organized and presented.
If applicable, structured as a fixed or partial success-based fee tied to whether the requested custody change is granted, agreed separately in the retainer agreement.
Costs such as obtaining school/medical records, expert consultation, or engaging an investigator for factual verification are billed separately as they arise.
Filing fees for the family court petition and any related mediation costs are calculated according to the court's fee schedule and are separate from attorney fees.

- Have you filed or received a police report or child protection agency (아동보호전문기관) record related to the allegation?
- Is there a protective order or provisional custody measure currently in place?
- Have you consulted a family law attorney about whether emergency provisional measures (임시양육자 지정 등) should be sought alongside the main petition?
