I need to do this later this week.

What docs do we need? Is there a list somewhere?

I know about the bank and that's ok.

Is this feasible? My retirement runs out in a week.

Thanks for the anticipated help.

What immigration office? You will need wife, marriage certificate and likely KR2 (if married here) or KR22 (if foreign marriage) and her ID card and home register (and copies). Photos together in and outside house and at least one with house or apartment number and another with clothing hung together. Map to home. The normal TM.7 and photo and fee. Bank passbook/copies and letter from bank of account balance. Two sets of copies often required.

You are aware retirement can be 800k or 65k or combination to meet 800k per year?

Lopburi,

Clothing hung together not needed now unless they have moved the target again. Not to my knowledge anyway but I am talking Chaeng Wattana HQ

Here is a rough guide.

(6) In case of marriage with a Thai lady,
the husband who is an alien must have an average annual income of not less than
40,000 baht per month or a money deposit in a local Thai bank of not less than
400,000 baht for the past 2 months for expenses within a year.

Letter from your Thai Bank showing balance

and up to date bank book.

OR.
If income from outside Thailand:

Letter from your Embassy showing income. Now may also need proof of income as back up.

If Income from Thailand: Statements showing Income Tax receipts.
Marriage Certificate. (Kor Ror 3)
Marriage Registry entry. (Kor Ror 2)
Wife's Tabbien Baan and ID Card.
Your Passport.
Copies of everything.
Photos of you and your Wife in and around the house

A map showing the way to your house.

Passport size photos and 1,900 Baht fee.
Take your Wife to be interviewed.One or two witnesses may be required.
You will be given a 30 day underconsideration stamp.
Go back in a month and get the remainder.

When I changed my marriage visa to retirement visa, the Tak Mae Sot office wrote a half a page note in my passport. I have no idea what it says, but it gave me the feeling that you cannot change from retirement back to marriage. Is that wrong?

You can change from Marriage Extension to Retirement Extension with no problem.

Samui Imm claimed I couldn't step back after changing but i've seen nothing to confirm they were factually correct.

Nothing in the rules say you can't change back and forth. The requirement is simply to have a non-immigrant visa.

How to convince them is another matter.

But what about Retirement Ext to Marriage Ext?

They will not be as anxious as more paperwork and not a local decision but if you can not meet the financials for retirement they should be willing to make the change.

Thanks for all the help here. Do I have to download a form from somewhere on the net?

Also: Can I have n\an appointment at Chiang Mai?

The form is the normal TM.7 that you use for any extension of stay. As for appointment believe they are booked well ahead so you have to arrive early and get a queue number in Chiang Mai
