What documents are required for a Retirement extension in Thailand?

@Roger *******

The point is to be an official inhabitant in your town. It gives you some legitimacy in front of officials. I use it to open banks accounts, to renew my driving licence, to report my address at the immigration (TM30), to attend the villagers meeting and vote on infrastructure matters, to pay Thai entry fare in the national park of my province, etc.. And many were happy to have it in August last year when only residents were allowed to enter Thailand. Beside you get a lifelong ID number you can use on official documents instead of the passport number that changes every 10 years.

And if your wife agrees, you can be listed as the head of the household as well.
