What are my options for extending my Non-O visa (family) in Thailand without marriage documentation?

because of your nationality you can just 'border-bouce' <- go to the border, stamp out of thailand, stamp in&out of another country and stamp back into thailand to get a 30 day visa exempt entry OR you can go to a thai consulate in another country and buy a single entry tourist visa.

I'd say IF you haven't gotten any 30 day visa exempt entries yet this year, a border bounce would be the thing to do and would get you a 30 day entry stamp.

with out the marriage documents you aren't going to get ANY extension inside the country OR even get a new visa from a thai consulate in a nearby country either. :/ :(

Depending on your nationality, your best bet would be to go to a thai consulate in a neighboring country and get a single entry tourist visa (that would get you stamped in for 60 days)

What country is your passport from?

No matter where you married, IF you're married to a thai you should be able to get an extension based on marriage. There is no rule that you have to have been married IN thailand.

You should be able to get the year extension (if you meet the requirements) OR you should be able to get a 60 day 'visit family' extension (this doesn't require proof of funds).

I would say go to the immigration office and see what the requirements are for a 60 day visit family extension based on marriage to a thai national.

First off there is no 30 day extension available on a Non-O visa.

is the 90 day non-O based on being married to a thai?
