Do I need my wife's involvement when changing my address for immigration in Thailand if my visa is based on marriage?

I’m in Phuket. When I change residences, I just include it in my visa renewal process with a tm30 and new address on my forms

Nope she doesn't need to be involved in your changing your address at all (unless you want her to tag along)

Depending on the office you might have to file a TM28 (change of address) form and your land lord or you will have to file a TM30 (notification of foreigner in residence) then you'd be registered to use that immigration office for your 90 day reporting and your next extension when it comes due

Changing the reason for the extension isn't going to be tough to do when you go for the next yearly extension, you just apply for one based on retirement instead of marriage
