When You and Your Siblings Cannot Settle the Division of the Estate

If you line up the numbers and documents before emotions take over, both negotiation and adjudication become much easier.

• List the real estate, deposits, stocks, insurance, vehicles and debts as of the date of death in one table. Leave blank anything you do not know.
• Write down what you know about money, homes or wedding funds your siblings received during the parent's lifetime, and look for registry records or transfer records.
• If you cared for your parent or paid hospital bills, gather transfer records and medical records showing the period and amounts.
• Do not delete messages exchanged during the negotiations or any draft agreement the other side sent; save them.
• Mark the inheritance tax filing deadline (6 months from the last day of the month of death) on a calendar.

• Stamping an agreement 'for now' when you do not fully understand it
• Leaving your registered seal and certificate of seal impression with one sibling
• Breaking into your parent's home or removing belongings during a dispute with the sibling living there
• Posting criticism of a sibling in the family group chat
• Withdrawing and spending the deceased's deposits without the other siblings knowing

With three children, each statutory share is one third, and if there is a spouse, the spouse's statutory share is 1.5 times one child's share. But in an actual division, property received in advance during the parent's lifetime (special benefit, 특별수익) is added back for the calculation, and the contribution share (기여분) of anyone who specially supported the parent is set aside first. So 'equal shares by law' can actually produce an unfair result.

Under the amendment of March 17, 2026, gifts received in return for specially supporting a parent are no longer treated as special benefits to that extent. If one of the siblings received such a gift, this must also be included in the calculation.

In a blended family, the calculation becomes more complex. A stepmother or stepfather whose marriage was registered is a co-heir as a spouse, and children from the father's earlier marriage and from his later marriage have equal shares. On the other hand, a stepmother's child from a previous relationship is not the father's heir unless he adopted them.

Division by agreement requires the consent of every heir, so if even one objects, there is no agreement. In that case, one heir can register the inheritance in all the heirs' names according to their statutory shares. However, the objecting sibling's share is registered too, and this is not a final division reflecting special benefits or contribution shares.

If a sibling cannot be reached at all, an administrator of an absent person's property (부재자재산관리인) must be appointed first, and if an heir is a minor, a special representative (특별대리인), before either an agreement or an adjudication can go ahead.

Before you stamp an agreement your sibling sent, check each of the points below. Once stamped, an agreement is hard to undo.

• Whether any deposits, insurance, vehicles or lease deposits are missing from the list of assets
• Whether the lot numbers and shares of real estate and the account numbers of deposits are written correctly
• Who takes on the debts, and whether the loans can be transferred into that person's name
• Whether it says how assets discovered later will be divided
• If you are to receive a settlement payment, whether the amount, the payment date and what happens if payment is late are written in

If agreement proves impossible, you ask the family court for an adjudication on division of the estate (상속재산분할). The person filing names all the other heirs as respondents, and because mediation must come first in these cases, a mediation date is usually set first. To claim a contribution share, you must file a petition to determine it together with the request for division.

During the case, orders to submit financial transaction information are used to confirm money the siblings received, and the market value of real estate is set by appraisal. If mediation succeeds, the estate is divided on those terms; if not, the court decides by adjudication who gets what and any settlement payments. Including mediation, it usually takes around a year.

Jisan Law first gathers the list of the estate, lifetime gifts and records of support, and prepares a table calculating each person's specific share. Based on that table, we put forward a settlement proposal or review the agreement the other side sent, and if agreement fails, we pursue an adjudication on division and a contribution share claim.
