Inheritance Division vs Reserved Portion Key Differences Explained

The two concepts that get confused most often in inheritance consultations are "inheritance-property partition" and "legal portion." In consultations, I see many clients ask, with the two concepts conflated, "do I have to share property already received?" or "how do I calculate money borrowed?" This article compares the two concepts step by step — definitions, objects, jurisdiction, procedure — and lays out the borderline cases that get confused most often.

Let me first draw the line precisely on definitions

• Inheritance-property partition: The procedure for deciding, among the heirs, how the property the deceased left at the time of death will be divided. The core is "what is left, and to whom and in what amount it belongs."
• Legal-portion restitution claim (yuryubun): Where the deceased transferred too much property to a specific person through inter vivos gifts or bequests, this is the right to claim restitution from that donee or beneficiary to secure, at a minimum, a defined ratio of the statutory inheritance share (typically half of lineal descendants' and spouses' statutory shares).

First borderline issue: "money borrowed from the father" — where does it go?

The question that comes up most often in consultations. "I borrowed money from my father (the deceased). Shouldn't that be reflected in the inheritance-property partition?"

• The father (the deceased) is the creditor, the child is the debtor — so the "father's claim" is the deceased's property and is typically inheritance property.
• However, deposits, monetary claims, and other "divisible claims" are typically not the object of inheritance-property partition. At the time of death they are automatically divided among the heirs according to their statutory shares.
• Therefore, a claim against the debtor (the child who borrowed money) typically must be pursued not in the Family Court's inheritance-property partition adjudication, but in a separate civil action in the Civil Court.

In consultations, this is the point that frustrates clients most. The question "why can't the Family Court handle everything at once" almost always comes up. Note up front that an inheritance-property partition is a non-contentious procedure that decides only "the method of division" and typically cannot issue an order to "pay money."

Second borderline issue: exceptions to "deposits are not subject to partition"

The principle is "deposits / monetary claims are automatically divided among heirs by statutory share upon death and are not subject to inheritance-property partition." But there are exceptions.

In such cases, Supreme Court precedent has typically allowed deposits and divisible claims to be exceptionally included in inheritance-property partition, allowing re-division based on the "special inheritance share." For example, where the eldest son took all the real estate, simply "splitting the remaining deposits in half" is typically blocked.

Procedural difference — why, after going to the Family Court, you have to go to the Civil Court too

• Family Court inheritance-property partition adjudication: A non-contentious procedure that typically decides "how much to whom." Witness examination is generally limited, and the court leads the flow of the procedure.
• Civil Court legal-portion restitution / monetary claim litigation: An ordinary civil action in which an order to "pay" a specific amount is generally available. Witnesses can be called as needed to multi-dimensionally prove the substance of the family dispute (who was more filial, who contributed to support, etc.).

In consultations, the fact that procedure splits in two — even for the same intra-family dispute — typically heightens client fatigue. So when preparing an inheritance-property partition adjudication, we recommend mapping out the "full picture" together with monetary claims and legal portion, and then proceeding in stages.

Third borderline issue: learn the term "special benefit" in advance

About half of inheritance disputes are typically over "special benefit."

• Special benefit: Among property an heir received through inter vivos gifts or bequests, the part that has the character of an advance on the inheritance share.
• Items that typically become disputes include marriage-fund support, study-abroad expenses, real-estate gifts, business-funding support, etc.
• Not all prior support is recognized as special benefit. Typically the key is whether it falls within the "ordinary range of parental support" or constitutes a "special benefit beyond ordinary support."

Are study-abroad expenses or living expenses also special benefit?

In consultations, I am often asked, "is KRW 100 million in study-abroad expenses a special benefit?" The answer is typically "it depends on the case."

• The parent's means, equity with other children, the nominal purpose of the support, and the timing of the support are evaluated comprehensively.
• If the amount is very large relative to the parent's means, or if other children did not receive comparable support, recognition as special benefit becomes more likely.
• Conversely, if it falls within the parent's means and amounts to ordinary parenting and education expenses, it may not be recognized as special benefit.

Summary comparison of the two procedures

• Inheritance-property partition: "How will the remaining property be divided?" → Family Court, non-contentious procedure
• Legal-portion restitution claim: "Can I recover part of the property already taken?" → Civil Court, ordinary civil litigation
• The two procedures typically run together, and the key point is that even within the "same family dispute," procedure and jurisdiction differ

Frequently asked questions

Q. My brother received KRW 500 million from our father as business funding. Can I have those KRW 500 million reflected in the inheritance-property partition so I receive more?

A. If it is evaluated as a "special benefit," for the inheritance-share calculation, your brother's KRW 500 million is treated as an advance, reducing his remaining share and increasing yours. However, the nature of the business funding, the parent's means, and equity with other children are all evaluated together, so the concrete evaluation of your case should be reviewed with an attorney.

Q. Can I run an inheritance-property partition adjudication and a legal-portion restitution claim simultaneously?

A. Yes, typically. However, the jurisdictional courts differ and the procedural nature differs, so to optimize the outcome, the schedule, materials, and strategy of the two procedures must be designed together. To avoid the situation of "having to restart 2–3 years later," I recommend integrated planning with an attorney from the outset.

Closing

Inheritance-property partition and legal-portion restitution claims are typically both "the same family dispute," but they differ entirely in their starting points, objects, jurisdiction, and procedure. Distinguishing the two concepts precisely from the start typically reduces the overall schedule and cost of the dispute significantly. If an inheritance dispute is imminent or already underway, I recommend checking integrated planning with an attorney as early as possible.
