Can I submit the TM30 paperwork on behalf of my landlord in Chiang Mai after returning from a trip?

The user is seeking advice on whether they can submit the TM30 paperwork to immigration on behalf of their landlord while planning a trip outside Thailand. They mention that their landlord resides in Bangkok and want to avoid the landlord's travel to Chiang Mai just for this process. Comments from others suggest that typically copies of the landlord's Thai ID, property deed, and possibly a signed power of attorney may be required. Additionally, it was noted that if the user has a previous TM30 from when they moved in, they may only need to bring that to immigration for a new stamp instead of submitting a new TM30.
