I got divorced 3 years ago in bkk now need papers to prove this in uk but don't have anything even office of marriage and divorce ...

Any amphur in Thailand will be able check if you are divorced, and should be able to give you a document to confirm this.

But if divorced at the court, you might need the divorce decree from the court.

Are you saying you do not know where you were married? You get divorce at the same office from my understanding. Even a map of Bangkok can not jog your memory?

No idea... In uk .. Need help!

Are you sure you really got married and divorced in Bkk?

I got married 4 years ago at the Sathon District Office in Bangkok. If, by chance, the OP also pledged his troth to his ex-tiirak there, might his memory now be sufficiently jogged, I wonder?

you do not have to get divorced at same Amphur office that you got married.

I was married at Amphur office in pong Thong Roi Et in 2001 and just get divorced in Thong Lo office Bangkok today !
