Does my Thai wife need a TDAC if she travels on her Thai passport?

Need a clearer THIM and TDAC explanation? Read the THIM guide on thim.in.th.

Sorry to ask another Tdac question as I can see there has been quiet a few lately.

I am travelling next month on a UK passport with my wife who is Thai, she will be leaving the UK on her UK passport but entering Thailand on her Thai passport.

So will she actually need a TDac? If so would she need to enter her Thai passport details or her UK passport details?

Thanks for any help on this.
Answer summary
The questioner is inquiring whether their Thai wife needs a TDAC, given that she holds both a Thai and a UK passport. According to community feedback, Thai nationals entering Thailand on their Thai passport do not require a TDAC. If she were to enter using her UK passport, then she would need to submit a TDAC using the UK passport information.

Anyone entering on a Thai passport doesn’t need a TDAC.

All and only foreigners (who with foreign passport (s)) need to submit TDAC. Thai nationals don't.

That means, if she enters Thailand using a Thai passport, she doesn't need to do TDAC. In case she enters Thailand with a UK passport, she needs to submit TDAC with UK passport information.
