Why compare an estate administrator with direct management?
An inherited estate does not pause while the family identifies heirs, locates documents or agrees on who will act. Property fees, insurance, taxes, tenant questions, business obligations and preservation work can continue every month. Looking only at the court petition cost may make appointment appear too expensive, while treating family work as free may make direct management appear artificially cheap.
This Korea-specific calculator places both plans on the same 6-, 12- and 24-month timeline. It separates cash outlay from the economic value of an heir's time and an assumed loss of estate value caused by delay, vacancy, arrears or physical deterioration. It also estimates the cash shortfall against funds available now and shows a simple cumulative break-even point.
A lower number is not a legal recommendation. Under Civil Act Article 1053, where it is unclear whether an heir exists, the direct-management column is only an economic benchmark for the management gap. It does not mean that an identified heir is legally available to take over.
Identify the legal route before entering costs
Korean law uses estate-management mechanisms in different factual settings. The calculator cannot decide which provision applies, standing, jurisdiction or whether the court will appoint anyone. Select the closest planning route, then verify the legal route with the competent Family Court or Korean counsel.
Civil Act Article 1053
If it is unclear whether an heir exists, the court may appoint an estate administrator upon the petition of a relative, an interested party or a prosecutor and must publish notice without delay. Discovery and acceptance by an heir can end the administrator's duties and trigger an accounting.
Civil Act Article 1040
Where there are multiple co-heirs, the court may appoint an estate manager from among those co-heirs. That person represents the co-heirs in estate management and debt payment. This route does not automatically create an outside professional administrator.
Civil Act Article 1023
Before acceptance or renunciation is settled, an interested party or prosecutor may request a preservation measure. Timing and the measure's temporal reach require urgent review in light of Supreme Court order 99Eu1.
Comparison of Korean inherited-estate management routes| Route | Core fact | Potential manager | Priority question |
|---|
| Article 1053 | Existence of heir unclear | Court-appointed administrator | Notice sequence and heir discovery |
| Article 1040 | Co-heirs need a manager | One of the co-heirs | Representation and cost sharing |
| Article 1023 | Preservation before election | Court measure or appointed manager | Urgency and permissible timing |
What the verified 2026 rules establish
Statutory filing fee versus case-specific spending
The Family Litigation Act classifies measures under Civil Act Articles 1023, 1040 and 1053 as Category Ra family non-litigation matters within Family Court jurisdiction. Under Article 3(1) of the Family Litigation Fee Rules, the petition fee for a Category Ra matter is KRW 5,000. Applying the 90% electronic-filing rule in Article 8 gives a planning value of KRW 4,500. Filing availability and the receiving court's actual payment instruction control.
Publication, service, remuneration advances, inventory work, appraisal and professional assistance are not universal fixed prices. The Family Litigation Rules apply property-manager provisions to these inherited-estate proceedings and address expenses charged to managed property, notice costs and certain appraisal expenses. The amount and timing still depend on the court order, the estate, the number of interested parties and the scope of professional work. That is why every such field starts at zero.
Cash advanced now is not necessarily final personal cost
Supreme Court order 2000Eu2 explains that an applicant may be directed to advance administrator remuneration even though the ultimate burden may be placed on the managed estate under Civil Act Article 26 and the applicable procedural rules. The calculator therefore includes an entered advance in immediate cash need. It does not state that the full amount will remain the applicant's personal economic loss or that it will be refunded.
Automatically applied
- Paper petition fee of KRW 5,000
- Electronic-filing planning fee of KRW 4,500
- Simple 6-, 12- and 24-month horizons
You must supply
- Notice, service, advance and appraisal estimates
- Professional quotes and monthly administrator estimate
- Direct work hours and plan-specific value-loss rates
How the calculator treats the Article 1053 timeline
Civil Act Article 1053 requires prompt publication after appointment when heir existence is unclear. Under Article 1056, if the issue remains unresolved three months after that notice, the administrator publishes a creditor-and-legatee claims period of at least two months. If uncertainty remains after that period, Article 1057 provides for a court notice asking heirs to assert their rights within a period of at least one year.
First statutory interval
3 months
Measured after the initial appointment notice before the next notice stage may arise.
Claims notice period
At least 2 months
For estate creditors and legatees to report their claims.
Heir-search notice
At least 1 year
For an heir to assert a right after the claims-notice stage.
These are statutory intervals in a sequence, not a service-level promise. Corrections, service, investigation, asset work, discovery of an heir and disputes can change the actual duration. A 12-month calculator row must never be read as a prediction that an Article 1053 case will finish within one year.
Inputs and formulas
Appointment plan
- Initial cash includes urgent preservation, the statutory filing fee, notice and service, remuneration advance, inventory or appraisal and petition assistance.
- Monthly cash includes common estate upkeep, estimated administrator remuneration and other recurring procedure cash.
- Economic cost adds the plan's assumed monthly loss of estate value.
Direct-management benchmark
- Initial cash includes urgent preservation, documents and any initial professional help.
- Monthly cash includes common upkeep, travel, site work and other recurring spending.
- Economic cost adds monthly hours multiplied by hourly value and the plan's assumed estate-value loss.
Core equations
- Monthly value loss = gross estate × annual loss rate ÷ 100 ÷ 12
- Funding gap = max(horizon cash outlay − available cash, 0)
- Net estate after cost = gross estate − confirmed debts − horizon economic cost
- Break-even month = initial-cost difference ÷ monthly economic-cost difference
The break-even formula assumes that monthly costs and loss rates remain constant. It handles equal plans, a plan that is lower from the start and a future crossing in either direction. It is an arithmetic budgeting indicator, not a forecast of appointment, court permission, heir discovery or case completion.
Worked synthetic example
The built-in example validates the arithmetic; it is not a market average, court schedule or recommended quote. It assumes a KRW 300,000,000 gross estate, KRW 80,000,000 of confirmed debt and KRW 8,000,000 available cash. Common costs are KRW 500,000 initially and KRW 450,000 per month.
The appointment plan uses a KRW 5,000 paper fee, KRW 300,000 notice and service estimate, KRW 3,000,000 remuneration advance, KRW 1,200,000 inventory and appraisal estimate, KRW 800,000 professional cost, KRW 400,000 monthly administrator estimate, KRW 100,000 other monthly cash and a 1% annual value-loss assumption. The direct benchmark uses KRW 300,000 of documents, KRW 700,000 of initial advice, 20 monthly hours at KRW 30,000 per hour, KRW 150,000 monthly travel, KRW 100,000 other monthly cash and a 3% annual loss assumption.
Synthetic example results by planning horizon| Horizon | Appointment cash | Appointment economic | Direct cash | Direct economic | Difference |
|---|
| 6 months | KRW 11,505,000 | KRW 13,005,000 | KRW 5,700,000 | KRW 13,800,000 | KRW 795,000 |
| 12 months | KRW 17,205,000 | KRW 20,205,000 | KRW 9,900,000 | KRW 26,100,000 | KRW 5,895,000 |
| 24 months | KRW 28,605,000 | KRW 34,605,000 | KRW 18,300,000 | KRW 50,700,000 | KRW 16,095,000 |
Appointment initial cash is KRW 5,805,000 versus KRW 1,500,000 for the direct benchmark. Monthly economic cost is KRW 1,200,000 versus KRW 2,050,000. Dividing the KRW 4,305,000 initial difference by the KRW 850,000 monthly difference gives about 5.0647 months. At 12 months, net estate after debts and modeled cost is KRW 199,795,000 for appointment and KRW 193,900,000 for direct management.
The appointment plan has the lower 12-month economic estimate but a larger immediate funding gap in this example. Economic efficiency and short-term liquidity are different questions, so review both columns before consulting the court or a professional.
Step-by-step use
- Separate an unknown-heir case, a co-heir management issue and urgent preservation before acceptance or renunciation.
- Build a dated inventory of real estate, deposits, vehicles, businesses, lease deposits and confirmed debts.
- Enter only cash available now for petitions and management, not a hoped-for future sale price.
- Enter urgent preservation and recurring property, storage, insurance, tax, tenant and business costs common to both plans.
- Replace zeroes with the receiving court's notice, service and advance instructions and written professional quotes.
- For direct management, include coordination, travel, site visits, ledger work, filings and the cost of replacing that time.
- Develop separate, supportable annual value-loss assumptions for each plan rather than using an unexplained penalty rate.
- Read the 6-month liquidity, 12-month comparison and 24-month cumulative exposure together.
- Take the table, warnings and document checklist to a Korean lawyer, judicial scrivener or the competent court for verification.
Practical scenarios and commonly omitted costs
Vacant property or an active lease
Include building fees, fire insurance, freeze prevention, lock changes, tenant communication, inspections and urgent repairs. Model delayed rent collection or deteriorating property separately as value loss if it differs between plans.
Operating business and employees
List payroll, rent, suppliers, inventory, account access and tax filings that cannot wait. Direct-management hours should cover calls, document collection, adviser coordination and bookkeeping, not just time physically on site.
Heirs abroad or far from the estate
Add transport, lodging, international delivery, translation, notarization, leave from work and time-zone coordination. Unpaid help still consumes capacity, so test a reasonable replacement cost instead of automatically assigning zero value.
Possible insolvent estate
This calculator does not rank or distribute creditor claims. If debts may exceed assets, separately review limited acceptance, renunciation deadlines, inherited-estate bankruptcy, secured rights and priority claims.
Building a value-loss assumption
- Estimate vacancy, arrears, discarded inventory, uninsured exposure and delayed repairs in KRW first.
- Convert the annual total to a percentage of gross estate and distinguish each plan's response speed.
- If evidence is weak, test low, base and high inputs and note where the comparison reverses.
- Use the same assumption for market or tax changes unrelated to the manager, or leave those changes out of both plans.
Frequently asked questions
Should I choose whichever plan has the lower result?
No. The result compares entered costs and liquidity. It does not determine standing, the need for appointment, available authority, heir existence or the court's decision. The direct column in an Article 1053 case is only a benchmark.
Will an administrator remuneration advance be returned?
The calculator cannot say. Order 2000Eu2 and Civil Act Article 26 show that an advance can be required and remuneration may ultimately be paid from managed property, but the actual order, payment and accounting control. The model conservatively records the advance as cash needed now.
Does an Article 1053 process finish in 12 months?
Not necessarily. The statutory sequence itself can connect 3 months, a claims period of at least 2 months and an heir-search period of at least 1 year. Investigation, corrections, service, asset work and disputes can add time. The horizons are budgeting windows only.
Can an outside professional be the Article 1040 manager?
Article 1040 states that the manager is appointed from among the co-heirs. The shared remuneration field is a budgeting input, not a statement that an outside professional will be appointed or that any amount will be approved. Confirm compensation and separate representation costs for the actual case.
How should I value family time?
Use a supportable measure such as lost earnings, paid leave consumed, business revenue displaced or the hourly cost of replacement help. If several people share the work, estimate each person's hours and aggregate them. Test more than one value when the assumption is uncertain.
Why do market-cost fields start at zero?
Notice, service, appraisal, advances and professional fees can vary materially by estate and court. An unsupported average would create false precision in the funding gap. The synthetic-example button is for learning and formula verification; replace every amount with actual instructions and quotes.

This calculator does not determine standing, jurisdiction, heir existence, appointment or removal, authority, court permission, remuneration, final allocation of costs, validity of acceptance or renunciation, tax, creditor priority, outcome or actual duration. It is arithmetic planning information, not Korean legal advice, tax advice, appraisal or a substitute for court instructions.
Turn the result into a consultation checklist
Build the estate and task inventory first, then replace every zero with receiving-court instructions and written quotes. Review 6-month liquidity, 12-month economic cost and 24-month value-loss exposure under more than one assumption. Take the comparison to a Korean professional and ask who may act, which costs can be paid from estate property, when an advance is due, what requires court permission and what evidence supports each entered amount.
