The list of documents required at Chiang Mai for a 1-year extension of stay base on Thai wife/children says, "In case of divorce must bring Divorce Certificate to show"

* Does that mean the legal proof of divorce previous to your current marriage? I mean, that's necessary in order to get a Thai marriage registration & certificate, which you need to include with the application anyway.

* Or is it for the case when you have divorced the mother of your half-Thai children?

My school hasn't been able to prepare all the necessary documents for me to be able to apply for an extension of stay in time. My current extension of stay will expire on the 9th of October. Is it possible to ask for a 30-day extension while I wait for the school to get everything in order?
