No, the CNI is obtained from either the Australian Embassy, Bangkok, or the Australian Consulate, Phuket.

Very straightforward for an Australian national to get married in Thailand.

Getting married in Thailand.

Step 1.

First and foremost, you should check the requirements at your local Amphoe office where you intend to register your marriage. Most Amphoes will at minimum require;

1. Your Passport.

2. Intended spouses Tabien Baan and ID card.

3. Embassy certified 'affidavit'' of certificate of no impediment to marry, translated to Thai, then legalised by the Legalisation division of the Consular department of Thailand’s MFA.

4. Embassy certified copy of Passport data page, translated to Thai, then legalised by the Legalisation division of the Consular department of Thailand’s MFA.

5. The marital status of your intended spouse can be checked on Amphoe online database for any previous record of marriage, or divorce. If your intended was previously 'widowed', or divorced, I recommend she takes her ex husbands Death or Divorce certificates as confirmed proof of her marital status.

Step 2.

Completing your affidavit of ‘certificate of no impediment to marry’ and make an appointment at your Embassy to also make a certified copy of your passport.

Most Embassies now offer a service to complete and submit the affidavit online.

Check the services and procedures available at your local Embassy for marriage in Thailand.

https://thailand.embassy.gov.au/files/bkok/Marriage%20instructions%20for%20website%20(290825).pdf

Usually you are required to allow a 7 day period from completing and submitting the affidavit to making the appointment.

Book an appointment to collect your affidavit of ‘certificate of no impediment to marry’ and for a certified copy of your passport data page.

At the appointment you should take the following documents;

1. Your letter/confirmation of appointment.

2. Your passport.

3. Your intended spouses Thai national ID card.

4. If previously married, a final divorce decree, or Death certificate of your ex spouse.

Step 3.

The ‘affidavit’ and certified passport copy must then be translated into Thai by a reputable translator. Avoid ‘touts’ waiting outside the Embassy offering their services.

I can personally recommend;

Step 4.

The below documents, now require ‘legalising’ by the Consular section department of Thailand's Ministry of Foreign Affairs for presentation and registration of marriage at your chosen Amphoe office.

1. The affidavit

2. Certified copy of passport data page

3. Thai translation of affidavit

4. Thai translation of passport data page

At this point you have two options to get your documents ‘legalised’ by the MFA.

1. Many agencies provide services to get the documents legalised on your behalf and once completed return them to a given address via EMS post.

This is an option you should discuss with the agency and agree a reasonable fee.

Express Translation Services offer such a service at very reasonable rates.

Allow several days for the documents to be returned.

2. Do it yourself.

For legalisation of documents by the MFA, appointments are necessary.

The MFA have now opened several centres to have the above documents legalised.

1. 123 Chaeng Watthana Road, Lak Si District, Bangkok 10210

I recommend you take good quality (preferable laser jet) photocopies of all your documents for future reference, before visiting your Amphoe.

Thanks. Very helpful.

Good list, but you forgot the first step - getting the original freedom to marry certificate from Australia that the embassy then certifies.

Also, you can submit the forms at Australian Embassy outreaches in Chiang Mai and if they do it in other locations, not just in Phuket and Bangkok - source, I submitted mine in CM last year.

I didn't forget anything.

Open the links I provided and you find the following;

To get married in Thailand, the Thai authorities require a Certificate of No Impediment to Marriage (CNI) to prove you're free to marry. We issue CNIs at the Embassy in Bangkok and Consulate-General in Phuket by appointment Monday to Friday (excluding Embassy public holidays). Fees apply.

You can download the CNI, print it and fill it in, or complete it electronically.

I have been living with my gf for seven years, what legal rights does she have under Thai law to my assets? She says that because we are not married, she is not entitled to any of my assets accumulated before we started living together.

De facto relationship counts for little in Thailand.

Even assets acquired after living together would require proof of where funds came from..

Bottom line for gf or wife best to have a WILL in place if (the norm) is to provide for them

Just now, Bees said:

She is correct.

Under Thai law any assets acquired before marriage remain the assets of the individual.
Only assets acquired after marriage can be considered as joint assets.

What exactly is your concern?

Exactly. OP asks question to facilitate marriage then left field assets in a de facto situation.
