What documents do I need for TM30 registration on behalf of an apartment owner in Thailand?

If landlord gives you power of attorney you still need Landlords Tabien Baan copy etc I believe.

My understanding is the owners documents are required. The landlord is not your girlfriend in this case. You need Landlords Tabien Baan, Thai ID etc

1. is Tabien Baan

Or

Hotel regustration

Or license to operate business etc etc... (in case of a hotel/guedthouse etc)

If its a private condo or house then ill be the tabien baan.

2. Is a power of attorney giving permission for someone else to register in his/her behalf.

If the owner agrees to let u use the platform then no need... u r acting as if he were doing it himself. (It does says for owners who do it themselves no need)

3. ID card of owner and authorized person (if any)

ALL DOCUMENTS must be signed with the "samnao tuktong" (สำเนาถูกต้อง)

So u add one.... specify the document name and then ADD another document etc

If all good u should be approved soon. I did it 8pm and had the password by lunch, but it depends on the province (samut prakarn for me).

Good luck!

When u register through the website (not the App) the 3 documents needed are clearly listed (in Thai).

I attach a picture and will translate in the next comment. But u r better off forwarding that to the owner who will need to give u these documents to upload.

Once the account is active u will receive user/id via email (make sure u use your email or ask the owner to then fwd the email to u)

U can then register urself but bear in mind its the owners name so im assuming he/she knows and agrees...
