ok, I understand your point.

If you return to Thailand and stay in a hotel (not a private house or condominium), then it’s much easier because the hotel can provide a full booking confirmation under your name, and they will normally handle the TM30 reporting as well.

In that case, you can use the hotel booking document as your proof of accommodation for the extension process.

Hi William , It is compulsory to attach the signed lease agreement, along with copies of both the tenant’s and landlord’s ID/passport, when submitting documents to the relevant government department. This ensures the submission is legally valid, binding, and effective.

This requirement applies regardless of whether the property owner is Thai or a foreigner.

Also, please note that Thailand Immigration does not directly “crack down” on lease agreements. Immigration’s role is mainly related to residency reporting and stay permissions. The Land Office is the authority that holds official ownership records, especially when there is a purchase agreement and the transfer of ownership is registered at the Land Office.
