We have friends who go through the marriage visa process every year. It's awful! Not worth it. Having to take the headman of the village with you, SO much paperwork, and headache.
We did ours ourselves. Went to immigration, got the forms, filled them out, got our landlord to sign it and give a copy of her ID and sign the copy. Go back to immigration and file it.
They might have you take a photo outside your house with the house numbers. Ask for all the documents you'll need when you get the forms. They will give you a list.
The ask:thailand community, consisting of multiple Q/A groups with over 100,000 members, powers this platform. It is not an official government resource. Our members actively contribute to this resource, and while we strive for accuracy, we cannot guarantee its complete reliability. Assistance to travelers is provided as a community service.
