Can a tenant submit the TM30 form at Chiang Mai immigration on behalf of the landlord?

When submitting the TM30 form for the first time in Chiang Mai, it's unclear if the landlord must be present. Comments suggest that many tenants have successfully submitted the form on behalf of their landlords with the necessary documentation, such as Housemaster and Names of Aliens forms, house registration, and landlord ID card. However, some users mention that a Power of Attorney might be required in certain cases, particularly in locations like Phuket, indicating varying requirements across regions.
