Sorry if this is a stupid question about tm30 we own a condo in Ban phe if my extended family go and stay do they have to submit this form, we used to live there but now just use it for holidays as far as I know we have never submitted one?
TLDR : Answer Summary
If your extended family members are foreigners staying at your condo in Ban Phe, you are legally required to submit a TM30 form within 24 hours of their arrival. This form registers the residence of foreigners and is necessary if they plan to apply for visas or extensions while in Thailand. You can use an app to quickly report their presence, fulfilling the legal requirement easily.
