Can my wife apply for a dependent visa in Thailand once I have a retirement visa, or does she need to return to the UK?

As a couple from the uk we have this problem, my husband got his retirement visa here in Thailand and I have had a tourist visa, until we go back to the UK and then I can be granted a non O visa to follow my husband (which the embassy in London said they will do) and then I am able to get a year extension here in Phuket to trail husbands visa (which I have been told here is possible)

So not so easy but doable and worth it once it’s done

Good luck

If my understanding is correct once

@Tony ********

is in Thailand and gets his extension of stay based on retirement his wife can apply for a extension of stay as a dependent no matter what visa she has arrived, meaning if she has a 60 day TR (add 30 extension in country) she will get her extension based of being the wife of Tony with no additional financial requirements. Am I correct?

Basically, your wife under 50 can get on Non-O dependent on you (so-called piggybacking) as the main visa/extension holder.

BUT

If you are applying for single entry Non-O based on retirement/pensioner in UK or inside Thailand, nearly zero chance for her to be able to get Non-O dependent inside Thailand/around Asia.

Generally, you can apply for Non-O dependent for her at the same time as when you apply for Non-OA (in your home country) or Non-OX (in your home country or at the immigration office in Thailand). You may need to contact the embassy or immigration office where you want to apply for details directly.
