@Maestro is correct. According to the OP, his son entered as a Tourist (VE/TV?) To piggyback his Fathers' extension, he must have Non Immigrant status. He can apply for the change of status (Non O) at his local Immigration office. Procedure here; VE-TV to Non O Dependant.pdf No. 8 on this list; https://bangkok.immigration.go.th/en/issuing-and-changing-type-of-visa/

Online, 14 days before the due date, up to and including the due date.

If you ask a bank, they'll tell you most Thais are aware of their spouse ATM card PIN's and withdraw the maximum daily amount until empty, before they notify the bank of their demise. Provided you are the sole beneficiary of the estate under law, then there is no comeback. This is where making a Will is a necessity IMO.

The POA ends for me, but the wife still has the power to sign for funds or transfer. I also stated there is a Will in place.

Really, can you provide a link to that information, or is it just your opinion.

It does? Have you read the conditions of the POA we jointly signed, and how!

As I've been stating. There is a legal procedure to follow to have foreign documents authenticated to be acceptable as genuine by Thai authorities.

We're not in the UK. Different Country, different laws. https://www.samuiforsale.com/knowledge/inheritance-laws-thailand.html

For Immigration purposes, the account must be in the foreigner's sole name. You can add a person to your account though by signing a Power of Attorney form that the bank provides, which gives them access to your account, but on statements, letters etc, only your name appears. Hell, Bangkok bank even gave my spouse a separate debit card for my account when I gave her POA. To navigate through the Thai Inheritance laws of succession after death, a simple Will suffices as to who inherits the deceased estate and avoids the probate process. (Unless someone contests the Will).

Thailand doesn't have Notaries as such, they have lawyers approved to act as a Notary. I suspect what they told her is the document and translation must be 'legalised' by the MFA to be acceptable. No different from affidavits to marry or foreign diplomas to be accepted in Thailand.

No, they have an unauthenticated UK death certificate and a translation certified by a Thai lawyer. They're checking out the Death certificate is genuine along with if anyone else is entitled to the estate, as @OneMoreFarang pointed out.

They'll take no notice of a lawyer's letter. She'd need to sign a POA for the OP to conduct affairs on her behalf. My wife has POA to access my account and a Thai Will along with a Thai death certificate, Bangkok Bank assure me funds would immediately be released to my spouse in the event of my death on production of those documents. At minimum, the lady in question will require a Court Order to release said funds to her, after proof she alone is entitled to said funds.

True, but having explained the issue, they have Thai staff that can advise the widow. The first advice that I'd follow, that the BE listed, is to ask the bank 'exactly' what they require as proof of her husbands' death.

There is a legal procedure to follow to have any foreign document accepted as legitimate by Thai authorities. As with marriage to a Thai, the BE can attest an affidavit to marry, but if widowed/divorce you must produce said document. This is because the BE have access to Public records in the UK. (Birth, Death, Divorce) and can authenticate those documents as being genuine. Alternatively, they may tell you that the UK death certificate should be first authenticated by the Home Office in Milton Keynes, then legalised by the Thai Embassy in London. This is then translated into Thai and legalised by Thailand Ministry of Foreign Affairs. Without that vignette being attached by the MFA, the document could be a forgery. I suspect the bank are making enquiries through the British Embassy to authenticate the Death certificate is genuine - could take months. I'd advise you contact the BE yourself.

How can a Thai lawyer authenticate a UK death certificate. The correct procedure is to have the British Embassy authenticate the document, then have it translated, then legalised by Thailand's Ministry of Foreign Affairs. Only then will it be acceptable as a genuine foreign document by the bank - hence their enquiries. It's also no longer a 'joint' account per se.

Provided you can prove 12 x 65K minimum monthly overseas transfers, you meet the financial criteria. 35-2561 (2019 (changed clause 2.22 of 327-2557 ENG.pdf This was an amendment to the requirements issued after the UK, US and Australian Embassies ceased the Income letters, to accept monthly overseas transfers to a Thai bank as an alternative.

What method did you use to obtain your extension last August? 800K funds in a Thai bank, 12 x 65K monthly overseas transfers, or a combination of both. 35-2561 (2019 (changed clause 2.22 of 327-2557 ENG.pdf

You only need to supply copies, not the originals, for a 1-year extension. Never in 10 years have I supplied, or, the original Tabien Baan been requested.

Yep, agreed, but the point I was trying to make went over members heads. If you've exited and re-entered in-between a 90-day report, you're still able to submit online on the due date. The system doesn't know you've exited and re-entered. Of course, you can count 90 days from re-entry and submit within the 14-day window, but my particular IO will not approve these applications, stating foreigners frequently enter the wrong dates, so they insist you go in person the first time after re-entry.

Unless you're changing permanent address or are a new visitor to Thailand.

Immigration Act B.E. 2522 (1979) ENG.pdf Section 38 : The house – master , the owner or the possessor of the residence , or the hotel manager where the alien , receiving permission to stay temporary in the Kingdom has stayed , must notify the competent official of the Immigration Office located in the same area with that hours , dwelling place or hotel, within 24 hours from the time of arrival of the alien concerned. Definitions in the Act; Section 4: “ House Master ” means any persons who is the chief possessor of a house , whether in the capacity of owner , tenant , or in any other capacity whatsoever , in accordance with the law on people act. You can register online and file as the 'tenant'.

The owner, the tenant, or the possessor in any capacity whatsoever can file a TM30.

It's strange to understand Jack that you accept certain Immigration offices conform to what is expected, whilst others don't regarding the TM 30, yet you fail to accept there may be a difference between IO accepting online 90 day reports when you've been out of Country.

I never stated such, your comprehension to understand what's written is lacking. They did that, but perhaps the IO didn't trust those dates and wanted to physically see the entry stamps.

Thanks, that proves another theory that each IO sets its own requirement. In the case of our experiment, the two who followed your example were told by the IO that they had to check their entry stamp date before resetting the 90-day clock, hence having to report in person.
