Just read the latest thread on TV (it does have it uses sometimes).
This is what the dude handed in...
* Application form with 2 passport photo's
* Copies of marriage certificate and registration)
* copy of the Mrs's Thai ID card and House book ( both signed)
* Copy of my passport ( signed)
* 5.000 THB
* Originals of the above.
I think that I went bit overboard with my paperwork, but better safe than sorry.
