The First Step for Foreigners: Understanding the "Affidavit of Freedom to Marry"
Congratulations on your decision to get married in Thailand! It's an exciting time, but the legal paperwork, especially for a foreigner, can seem confusing. The single most important document you will need is an **Affidavit of Freedom to Marry**, also known as a **Single Status Affidavit**.
This is a formal, sworn statement, made by you, declaring that you are legally free to marry. It confirms to the Thai government that you are:
- Legally single (i.e., not currently married to anyone else)
- Of legal age to marry
- Not under any other legal impediment that would prevent your marriage
This document is non-negotiable. You cannot legally register your marriage at any Thai District Office (known as an *Amphur* or *Khet*) without it.
Why Does the Thai Government Require This Document?
The Thai authorities have no access to your personal records in your home country. They cannot check if you are already married in Germany, the USA, Australia, or anywhere else.
To prevent illegal bigamy and ensure all marriages registered in the Kingdom are legally valid, they place the responsibility on your home country's government (via your embassy) and the Thai legal system (via notarization and legalization) to verify your single status. The Affidavit is your personal, legal declaration—made under penalty of perjury—that you are free to marry. This document protects you, your future spouse, and the legality of your marriage.
