How does the renewal of an O or OA visa work upon re-entry to Thailand?

I am an English man married to a Thai Lady .We married in Thailand . If I want to live in Thailand ,What is the best avenue /please ? I will retire from work on /24 . I am familiar with Thailand having visited 14 times so far .All advice will be listened to and gratefully received -Thanks .

I am told my Aust will is no good for Thailand. I have a condo and SML amount of cash with my estate agent for expenses she looks after and pays for me. Someone told me I can pay to get my Aust will verified and translated to Thai language. Is this correct? Or easier/cheaper to make a new will in Thai? I had no idea of this when I purchased the condo

I think what you’re describing only the non OA does this potentially dependent on your insurance and the border agent.

In my experience at the border they did it wrong twice and issued 1 year from that day, not visa or insurance dates.

Only OA visa and you need valid insurance to cover the year.

You are confusing the two visas

You’re confusing a Non OA visa and a Non O visa/extension off of one.

With the initial Non OA you get stamped in for a full year or as long as your health insurance is valid until. This means that if you bounce out just before the visa expires and have a new insurance policy for a year then you’d be stamped in for a “second” year. This stamp is not multiple entry and you’d need a re-entry permit to keep that date alive.

Most Non O visas these days are 90 validity and single entry. You’d be stamped in for 90 days and could then extend that for one year. This extension is not multiple entry so again you’d need a re-entry permit to keep the stamp valid.
