Tell that to Immigration, you may be surprised.

If you've previously filed a TM30 and have a receipt stapled in the back of your passport, you're OK. If you haven't already filed a TM30, then you need to.

Immigration will require an update KR2 or KR22. If you married in Thailand, it will be a KR2. If you married overseas but registered your marriage in Thailand, then a KR22. It's 20 BHT for a copy.

The key question here is contained in your question "When we visit Thailand" How many times and for what durations of stay would you visit Thailand each year. A Visa exempt entry would permit a stay of 30 days, which can be extended for a further 60 days. A Tourist visa entry would permit a stay of 60 days, which can be extended for a further 60 days. The Non Imm O-A visa is applied for purely on the reason of retirement (not marriage). The O-A visa is valid for entry for 1 year and each entry permits a stay of 1 year (intended for long stays, not 'visits'). The O-A visa must be applied for at a Thai Embassy/Consulate, in your case, from the USA. You must meet the financial requirements for retirement, that being the equivalent of 800,000 BHT in a US bank account, as well as a compulsory Health Insurance policy of 3M BHT is also required, and a Criminal record check.

Where do suppose they stay once arrested and waiting to appear in court, the Ritz hotel?

That was your experience, every case is different, dependent on the reason and length of overstay. According to the law, section 81 of the Immigration Act. Section 81 : Any alien who stay in the Kingdom without permission or with permission expired or revoked shall be punished with imprisonment not exceeding two years or a fine not exceeding 20,000 Baht or both.

Bangkok Bank (Head Office) 333 Silom Road, Silom, Bang Rak, Bangkok. Most banks now require a confirmation of your address in Thailand, as well as a referral from an existing customer, member of staff, or government official.

He could be fined and imprisoned.

Very few are brave enough to challenge them, though! 3 times I've challenged an IO and gone above his head. 3 times it turned out the IO had misinterpreted, misunderstood, plainly not familiar, or been ill-informed with Immigration orders.

No it's not. Section 38 of the Immigration Act states it's the responsibility of the housemaster, owner or possessor. Section 4 defines the "housemaster" as meaning, 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.

In my experience in these situations, it's because the IO you deal with is either trained, informed and competent, or untrained, ill-informed and incompetent.

Or he could just be imprisoned for up to 2 years.

Google is your friend. His Embassy can issue emergency travel documents, or Immigration may request another form of ID.

He can fly back to his Country of nationality without a valid passport.

What difference would that make?

The UK offer both the single and multi entry Non O visa based on Thai spouse. The financial requirements for both are listed on their website. https://london.thaiembassy.org/en/page/spouse-and-family-visa 3. Financial evidence, e.g. bank statements, proof of earnings, proof of sponsorship from a third party -Your recent official UK/Ireland bank statement shows your name, address, and a minimum closing balance of £500 (for individual single entry) £1,000 (for family single entry), £5000 (for individual multiple entries, and £10,000 (for family multiple entries), proof of earnings (payslips) or sponsorship letter from your sponsor with official ID and their Bank Statements.

Thanks. Did you receive the email reminders, or did you just self count the 90 days after returning to Thailand?

Interesting. Were your trips in-between 90 day report dates, or were you overseas when the reports were due.

Understood. I concur with @treetops. Your 90-day report is due Jan 2nd. The day of entry counts as day one of the 90 days. You're within the window to submit online now .......................... however I am doubtful it will work. I reinterred late July from overseas, but when I tried to submit my 90-day report in October, it failed. I had to submit in person and was told the reason was because I missed my previous report due in June. I was overseas at that time, but the IO informed me because I missed that report, the system didn't automatically predict a future report date. He stated I had to report in person so they could manually reset the report date. The local IO's have no access to when you departed or arrived back in the Country. If you cannot submit your 90-day report now, I suggest you file a new TM30 at the Immigration office within your location to change address, then they will process your 90-day report.

This doesn't make sense. You entered Thailand on October 5th, then obtained a 1-year extension of stay based on retirement from Bangkok through an agent? Your first 90-day report should be due 90 days from the date the extension was issued. What date was the extension issued? Usually, Immigration would place a notification slip in the back of your passport with your due 90-day report date.

If you're applying through a Thai Embassy/Consulate as your info graph suggests, then it's a visa. The question is how long do you intend to stay in Thailand, which usually dictates which visa type to apply for.

There is now no requirement to file either a TM30 or TM28 if you temporarily stay away from your permanently registered address, provided you later return to that permanent address. The new TM30 regulations made the purpose of the TM28 obsolete. The TM27 was introduced only to notify a change of address than that notified on a TM6, which is now also scrapped. Provided in the event of a permanent change of address, Immigration are notified via a new TM30, that is all they require. Why does the Thai Immigration website then not show the TM27 for download and still the TM28? Answer, because they are too lazy to update the site.

Yes.

Copies of the owner's ID and Blue book are required as proof of the address. If for any reason the owner will not supply these documents, you should inform your Immigration office. They have their methods of persuasion to obtain them. As an aside, I have a yellow book and successfully registered on the online TM30 site by uploading a copy of my passport data page, yellow book and pink Thai ID card.
