First published 2026-05-30 / Last reviewed 2026-05-30 This article summarizes the relationship between inheritance-property-division and yuryubun litigation and taxes, as covered in the YouTube above by attorneys Roh Jong-eon and Yoon Ji-sang of Jonjae Law Firm.
In handling inheritance cases, the most frequent tragedy I see is when emotions between siblings run so deep that they refuse to cooperate even on inheritance-tax filings and payments — and ultimately all the heirs lose together through penalty taxes and delinquency procedures. The single most important message of this video boils down to one line: "Inheritance disputes and taxes cannot be handled separately."
There is a structure to grasp first. Inheritance disputes typically run on three separated tracks.
- Family court — decides how the decedent's estate is to be distributed (inheritance-division petition, yuryubun-recovery claim)
- Civil court — settles money issues that arise after the decedent's death (inheritance-tax indemnity claim, unjust-enrichment recovery, etc.)
- Tax authority — inheritance-tax filing and payment, tax audit
In an inheritance-division petition, tax issues are in principle not within the court's scope. So disputes around inheritance tax usually move into separate civil procedures.
The most common misunderstanding I hear is "everything gets settled at family court at once, doesn't it?" Usually that is not the case. However, when both parties reach a settlement, the family-court mediation can sometimes close out tax issues at the same time.
Inheritance-tax filing — 6 months from the end of the month in which the death occurred
The inheritance-tax filing deadline is 6 months from the last day of the month in which the decedent died. Missing this deadline typically accumulates the following losses:
- Non-filing penalty
- Late-payment penalty
- Loss of usually available deductions (such as the filed-tax-amount deduction)
The video emphasizes: "If you do not file at all, the penalty is enormous." Even if you are in dispute among heirs, you should at least cooperate on the tax filing.
When disputes arise at the filing stage — three flows
Disputes at the filing stage typically take three forms.
- No one files, and the tax authority assesses ex officio
- A single representative heir files comprehensively
- Group A, Group B, etc. each file separately. Because the filings differ, the probability of a tax audit usually rises.
The third pattern is the most dangerous. Inconsistencies among the filings are themselves clues for a tax audit.
Who pays first — from a penalty-tax perspective
The most common question at the payment stage is "who pays first?" Inheritance tax in Korea is typically operated as follows.
- Korean inheritance tax is assessed on the decedent basis, and all heirs bear joint and several payment obligation
- The tax authority tends to assess against whoever is easiest to collect from
- Usual order: the decedent's deposits → real-estate seizure / public auction → seizure of an individual heir's assets
The video emphasizes: "If you have the basis to recover from the other party, paying first yourself is usually advantageous from a penalty-tax perspective." Non-payment penalties accumulate quickly.
Once the inheritance-division outcome later fixes your actual share, you can use an indemnity claim against the other heirs to recover the difference.
The real reason late tax is scary — speed of delinquency proceedings
Inheritance-tax delinquency is much more frightening than typical civil debt because of the speed and coercive power of the delinquency procedures.
- General compulsory execution takes time and requires preservation procedures
- Delinquency procedures typically execute seizure and public auction faster
- Even with personal bankruptcy, tax debts are not discharged
A real case introduced in the video illustrates this point. An heir who deferred inheritance-tax filing and payment received shares of an unlisted company that subsequently went under. The assets effectively vanished, while the inheritance tax remained, and the heir eventually ended up bankrupt.
Real-estate acquisition tax — another 6-month deadline you must catch
When you inherit real estate, the acquisition tax also has to be paid within 6 months. Missing it adds an acquisition-tax penalty.
- Even while the inheritance dispute is ongoing, acquisition-tax filing and payment must be handled separately
- One heir may pay first and then bring an indemnity claim against the others to recover
- An ongoing dispute is not a reason to extend the acquisition-tax deadline
Appraisal versus assessed value — how you file changes the result
Even if you file using the published assessed value, the tax authority may within a certain period conduct an appraisal and reassess at that figure. Court appraisals carried out during the inheritance-division petition or yuryubun lawsuit can also be used as tax data.
In the video, attorney Yoon Ji-sang recommends: "Because appraisals often hurt everyone, in the early stage we recommend a flow where the valuation method is agreed by negotiation as much as possible." Collaboration between attorney and tax accountant is usually decisive.
Tax audit — a tool you can use
A tax audit tends to be conducted when the inheritance estate exceeds roughly KRW 5 billion. The video emphasizes that a tax audit is not merely a burden — it can also be used as a tool.
- In litigation, the court typically only opens the decedent's accounts
- Opening another heir's accounts requires special justification
- By contrast, the tax authority audits with all heirs' accounts open
- So actively requesting a tax audit to identify special benefits is a viable strategy
Frequently asked questions
Q. The other heirs will not cooperate with the inheritance-tax payment. Do I have to pay everything first? A. If there are circumstances that allow you to later recover via an indemnity claim, paying first to stop penalty accumulation is usually advantageous. Still, you should decide after weighing your cash position and recoverability together.
Q. Can we settle inheritance tax and inheritance-property division in the same court at the same time? A. At the family-court petition stage, tax issues are typically outside the scope of judgment. But when both parties reach a settlement in family-court mediation, the allocation of tax burden can sometimes be settled at the same time.

Five tax items to check at the start of an inheritance lawsuit
I usually look at these five items together in early consultation.
- How much time is left in the 6-month inheritance-tax filing deadline from the end of the decedent's month of death
- Possibility of agreement on who and how to file the inheritance tax
- Whether you have the cash position to pay inheritance tax first
- Whether the real-estate acquisition-tax deadline is running on a separate track
- Whether the decedent's assets include unlisted stock, business interests, or other high-volatility assets
Organizing these five items in the first month usually proves decisive for protecting your share. The longer an inheritance lawsuit drags on, the more momentum the tax dimension builds.
