Do I have to pay my landlord a fine for not notifying them of my travel when applying for a non-O visa extension?

When applying for a NON-O visa extension in Thailand, it is necessary to ensure that your TM30, which registers your address with immigration, is updated, especially if you have traveled outside the country. The landlord is typically responsible for filing the TM30 but tenants should notify landlords when they return from a trip, as failing to do so can result in fines. The fine for a late TM30 filing is usually around 800 to 1600 baht. Some advise going to an immigration office directly to file a new TM30 yourself, if needed, especially if the landlord is unresponsive, since this process can be done efficiently.
