Quick question all.

Does anybody know hoe long the affirmation is valid for.

Can one get an affirmation and use it months (or a year) later and have no problems registering at Amphur?

I pass through Bangkok infrequently and try to avoid it and want to have a certificate ready to legally marry my traditionally married wife of six years when I have family over some time later.

Thanks all

It's valid for three months.
