Marriage in Mongolia

Hey ALL ;
Me and My gf planing to marry in Mongolia ;
We both not Mongolians but not from same countries as well...
she is from Belarus and im from Turkey  ,,
so anyone knows what is the procedurs in here ?
What kinda documents we need to prepare ?
How long does it take ?
as i guess i need to get documents like criminal records and document that shows never married before .  and health certificate ...

Not worth the hassle, as the paperwork seems endless, I assume you both live in Mongolia, as it is far from being a romantic place to go to as a  marriage destination,.  so why not take a summer break to somewhere like Hong Kong. Also heard that the wedding palace in UB refused to marry a couple as in their eyes an age difference was to great at fifteen years!
