Estate Already Divided, Then a Bank Account or Another Plot of Land Turns Up: Do You Start Over?

The siblings divided the estate carefully. They closed the accounts they knew about and transferred the land they knew about. Months or years later a letter arrives from a bank nobody had heard of, or a relative mentions that the deceased owned another plot in a neighbouring district. The first question is whether everything has to go back to court. The most accurate answer is: do not decide yet. Check the old court order and the papers you already have first.

This guide covers only the situation where property is found after the partition. For the overall picture of an estate, see the main inheritance guide. For the filing steps, see filing the petition for an estate administrator, and for land in particular see transferring inherited land at the land office.

The core answer

The order of work is this. One, read the court order that appointed the administrator and the summary of the earlier distribution. Two, decide whether the existing administrator can still act on the new asset. Three, if so, have the heirs sign a fresh partition agreement; if not, consider a new petition. Four, check the dates for limitation before letting time pass.

The rule (Civil and Commercial Code). Civil and Commercial Code Section 1732 requires the administrator to perform the duties, submit the accounts and distribute the estate within one year from the date referred to in Section 1728, unless the will, a majority of the heirs or the court sets a different period. Section 1733 provides that an approval or discharge relating to the accounts is valid only if the accounts were delivered to the heirs with the supporting documents at least ten days in advance, and that an heir may not sue over the administration of the estate more than five years after the administration ended. Section 1745 gives co-heirs joint rights and duties over the estate until partition is complete and applies the co-ownership rules in Sections 1356 to 1366 so far as they do not conflict. Section 1750 sets out how to partition: the heirs take possession of separate portions, or the estate is sold and the money divided, or the partition is made by contract, which needs written evidence before it can be enforced by suit. The limitation rules for inheritance claims are in Section 1754.

Our practical view. A newly found asset is usually a paperwork problem, not a quarrel. If the heirs are still on speaking terms, there are normally two real jobs: proving to the bank or land office who has authority, and recording a clear agreement to divide only the new asset. We do not want anyone to file a new petition unnecessarily, and we do not want anyone to divide things orally and argue about it later.

Hypothetical used throughout this guide: a family in Khon Kaen. Father Somboon has died and left three children, Pornthip, Thanakorn and Siriporn. The court appointed Pornthip as administrator two years ago. The siblings divided the house and the accounts they knew about. Later Thanakorn finds an old passbook from a branch in Udon Thani, and a relative says their father once bought a small plot of land in a nearby district.

1. Start with the Old Court Order: Is It Still in Force, and Does It Cover the New Asset?

Take out the certified copy of the order and the certificate of finality (if you have one) and answer three questions yourself.

1. Is the appointment still in force? Is the administrator alive, and has he or she not been removed or resigned? Is there any document showing the duties have ended, such as a court order discharging the administrator or declaring the administration complete?
2. Which property does the order cover? Does it say "all estate property of the deceased" or does it list specific assets? If it lists specific assets, an asset not on the list may fall outside the order.
3. Is the administration finished? Has the administrator done the accounts and distributed everything? Under Section 1732 the usual period is one year, unless the will, a majority of the heirs or the court sets a different period.

One caution. Section 1732 sets a one-year period for performing the duties, but it does not say in so many words that the appointment lapses automatically after a year. The practical result depends on the wording of the order, the facts and how the receiving office reads it. We therefore do not tell you that the authority continues or has ended; take the order to a lawyer or to the court registry first.

In the hypothetical, the order Pornthip received appoints her administrator "of the deceased" without limiting the list of assets, and no document shows a discharge or an end to her duties. That gives the siblings good reason to ask the bank and the land office whether the old order can be used. There is no need to rush to court yet.

2. What Was Found, What to Check, and the Likely Path

This table is a general guide. The real outcome depends on the wording of the order, the documents for the asset and the requirements of each office.

3. When the Existing Administrator Can Continue, and When a New Petition Is Needed

The administrator can often continue when the old order authorises management of estate property without limiting the list, the administrator is still in office, no document shows the duties have ended, and the office receiving the matter accepts the old order.

A new petition is often needed when the old order is limited to other listed assets, the administrator is absent or unwilling, the court has ordered the duties ended, or the office will not accept the old order for the new asset and the heirs think a clear order is needed.

Note that "the administrator can continue" does not mean the administrator decides the distribution alone. The administrator manages on behalf of the heirs. The new asset still has to be divided according to the heirs' rights or the will, and you should make a list of the additional assets that all heirs can see and agree on. If the administrator has not told the heirs or has gone silent, see administrator not distributing and not responding to heirs.

4. What Banks and the Land Office Usually Ask For

Each bank and land office asks for different papers. From general practice, the common items are as follows.

• A certified copy of the court order appointing the administrator
• A certificate of finality, which the court issues after the period the court sets
• The death certificate of the deceased and the administrator's ID card
• Proof of the asset, such as the account number or the title deed and land number
• Some offices also ask for the heirs' consent, or a document showing the division that the heirs have signed
• If the administrator is the same person as before, some offices may ask to see that the duties have not ended

The most economical approach is to telephone or write first and keep the reply in writing, so you know which documents are really needed before you spend time going to court. Please note that you should not try to get into the deceased's account yourself, for example by using the deceased's password or banking app. Access without authority may be an offence under the Computer Crime Act B.E. 2550, Sections 5 to 7. Use only the channels the bank sets.

A sample letter of enquiry to a bank follows. Adapt it to your case.

Re: Request for details of a deceased person's deposit account and the documents the bank requires
To: The Manager, ____ Bank, ____ Branch

I, ____, am the [administrator / heir] of Mr/Ms ____, who died on ____.
I have found evidence that the deceased may have held a deposit account with your bank (account number ____, if known).
The ____ Court appointed me administrator of the deceased's estate on ____ (case no. ____).
I enclose a copy of the order, the death certificate and my ID card.

Please inform me in writing:
1. Whether the bank holds an account of the deceased and what its status is.
2. What further documents the bank requires so that the administrator or heirs can proceed.
3. Whether the bank accepts the existing court order for this account or requires other documents.

I have not asked to withdraw money or close the account, and I ask the bank to freeze movements on the account
until the documents are complete. You can reach me at ____ (tel. ____).

Yours faithfully,
____ (signature)  Date ____

5. Dividing the New Asset: The Heirs Remain Co-Owners Until Partition

Section 1745 gives co-heirs joint rights and duties over the estate until it is fully divided, and applies the co-ownership rules in Sections 1356 to 1366 so far as they do not conflict with the succession book. So the newly found asset still belongs to the heirs jointly. It does not belong to whoever found it first, and it does not belong to whoever holds the papers just because the earlier division is finished.

Section 1750 allows partition by the heirs taking possession of separate portions, or by selling and dividing the money. If partition is by contract, it cannot be enforced by suit unless there is written evidence signed by the party to be held liable or its agent, and Sections 850 and 852 on compromise apply by analogy.

In practice you should sign a separate supplementary partition agreement stating:

• The old court order and its date, the deceased, and every heir entitled
• The asset found, with details that can be checked (account number, bank, branch, or title deed number)
• The shares or the method of division: who takes which asset, or whether it is sold and the money divided
• Who will deal with the bank or land office, and who bears which costs
• A statement that no other asset has been concealed, and how any further asset found later will be divided
• Signatures of all heirs and witnesses

If some heirs will not sign, or someone objects to the shares, this agreement does not work in full, and negotiation may need a mediator or may end as a partition suit. See siblings who refuse to divide in the main guide.

In the hypothetical, Pornthip, Thanakorn and Siriporn agree to split the money in the account found into three equal parts, and to sell the small plot of land and divide the proceeds. They write one agreement, sign it with two witnesses, and attach it to the old court order when they approach the bank and the land office.

6. Limitation and Time Limits: Check the Dates First

Do not conclude that "it is too late" or that "it is not yet time-barred". Check three things.

1. Section 1754. The general rule for inheritance claims is 1 year, and in principle no claim may go beyond the 10-year cap from the date of the deceased's death, unless an exception applies, for example an heir who possesses estate property under Section 1748, who can still claim division of the property he or she possesses even after the Section 1754 period.
2. Section 1733. An heir may not sue over the administration of the estate more than five years after the administration ended. That limit concerns an heir who says the administrator handled the estate wrongly. It is not the same limit as a claim for a share of a newly found asset.
3. The real dates. Write down the date of death, the date of the order appointing the administrator, the date each heir learned of the new asset, and the date the earlier administration ended.

An important warning: a demand letter on its own does not normally interrupt the limitation period. Do not wait just because you have sent one, and if any date is close, consult a lawyer immediately. This cannot be answered from hearsay; it needs the real dates and the documents.

7. Inheritance Tax

The Inheritance Tax Act B.E. 2558 taxes only the part of the estate that each recipient receives from each deceased person above 100 million baht, and the deceased's spouse is exempt, so most families are below the threshold. Finding a further account or a small plot of land therefore usually does not trigger this tax. If the total is very large, have a specialist check the current threshold and the types of property that count. Land transfer registration fees are a separate matter, set by the land office case by case.

8. Checklist

Before you do anything

• Keep the evidence you found: photograph the passbook or land documents and note when and from whom you learned of them
• Note the date of death, the date the court appointed the administrator and the date each heir learned of the asset
• Find the certified copy of the order, the certificate of finality and the summary of the earlier distribution
• Read whether the order covers all property or only listed assets

Check authority

• Is the existing administrator alive and are the duties not ended?
• Ask the bank or land office in writing whether the old order can be used
• If a new petition is needed, see filing the petition for an estate administrator

Divide and record

• Tell every heir about the asset found, leaving no one out
• Sign a supplementary partition agreement in writing, with every heir and witnesses
• Deal with the bank or land office and keep receipts and the papers you receive
• Check limitation first; if a deadline is close, consult a lawyer immediately

Check the old court order first, then decide whether you must start again. A newly found asset often does not mean starting everything over, but it does need the right papers and a written partition agreement.
