Also if I travel and go to a hotel do I have to register when I return.
Thanks in advance.
TLDR : Answer Summary
The user inquired about the necessity of filing a TM30 when living in Thailand with an unregistered spouse while on a visa exemption. Responses indicated that filing the TM30 is generally not necessary unless intending to apply for a visa extension. If extensions are planned, the TM30 should be filed upon arrival and when returning from travels, especially if further extensions are desired. It was also emphasized that the TM30 is usually the landlord's responsibility; however, failure to file doesn't incur heavy penalties unless you attempt to get an extension without it.
