I'm in UK national, have a Thai wife, we have a 18 month old son and live in Thailand. I would just check the latest documents needed for my son's passport application. This is the list from the UK HM Passport website, it seems a long list.

 

1. My birth certificate (full showing both parents)

2. Wife's birth certificate (translated and certified)

3. Sons birth certificate

4. 2 documents showing my address, do they need to be translated?

5. Marriage certificate (translated and certified)

6.Both our passports

7. Wife's change of name (translated and certified)

 

All the originals should have colour photocopies

 

Kind regards

Here's the list I used 9 months ago. Everything in Thai had to be translated. Nothing needed to be legalised.

 

Don't forget to get the application countersigned.

 

Many thanks mate

On that list I supplied it says bio data page of parent's passports. I actually copied every page, and nothing was said about it being right or wrong.

The good news is that once you have submitted all the documentation, the process is quite quick and painless.  The mother of my child is from Laos, and doesn't have a birth certificate, so I only had to submit a copy of her passport ID page.  Also, there is no requirement to be married.

True; but any translations should contain

• confirmation from the translator that it is an accurate translation of the original document  
• the date of the translation  
• the translator's full name and signature  
• the translator's contact details

I used a translation company that added an ink stamp to the bottom of the translations that contained this information.

Just a matter of interest, does the translation doucment need to get certified by the Thai MFA?

No.

For a UK visa application, as blackcab says it does not.

 

However, other countries, e.g. the Schengen states, do require MFA certification; so it's worth considering in case you ever want a side trip to Europe.
