in theory yes, every time you enter thailand you (or your landlord, or who ever owns the property) need to file a new TM30
now in practice IF you're not going to go to the immigration office for anything during your time here (no extension, no 90 day report, no certificate of residence) you can get away with not filing a TM30
Most people who live with their thai wife or have condos do it thru the online system here at this link
