Will be getting my affirmation to marry in Bangkok soon. To legalise the document can it be done in Chiang Mai or do i need to go to the ministry of foreign affairs in Bangkok? I ask as it's a 3 day waiting time there, would rather come back to CM!
TLDR : Answer Summary
The legalization of your affirmation to marry must be done at the Ministry of Foreign Affairs (MFA) in Bangkok. While some expats mention using agencies for assistance, the process should be performed in Bangkok due to the specific requirements, including translations and certifications that some services near embassies may provide. Chiang Mai does not have the same services available, and it's advised to handle all legal documentation directly at the MFA to avoid potential complications.
