A tenant with a rental contract is a "possessor" and has an obligation to do TM 30 when required.
When I put a new tenant in a condo I do the TM 30. No problem. For me to be responsible for a TM 30 when a tenant comes and goes during the tenancy is ludicrous. How would I know his movements? Even if I did what happens if I am not in Thailand at the time?
I understand that some IO's are a bit pedantic about requiring an owner to do TM 30, but tenants can do the TM 30 with a copy of the house book and rental contract. I know because I have tenants who have done it
