Sorry, before spouting off please read the relevant laws. Then read your rental contract. Finally, stick to the rules and the law and you will need no police or other protection from landlords like me. I protect my interests from bad renters who abuse, destroy, maltreat and neglect my property. You have every right to protect your interests as well. Please stick to Thai laws and don't import your home country rental agreements etc. Tenants, unfortunately, enjoy very little protection from landlord scammers who abuse the deposit system. - Tenants sometimes leave before a contract expires, leaving utility debts, damage and a mess behind. They might also leave with outstanding due rent. What would you suggest owners do to protect themselves in such cases? And yes, I do have the right once the tenant is in breach of contract to evict them immediately and also gain access to the property. I can prevent you from any further access to the property. I am the owner, you have an obligation to pay rent for the use of such property. If you fail to comply with the terms of this agreement, then you forfeit the right of access as well as any deposit paid. You are the one breaking the law. - If the tenant complies with all aspects of the rental contract as well as relevant Thai law, and the landlord does not by refusing to refund the deposit or part thereof (explaining and reflecting all reasonable deductions) or in any other way, then you must of course seek a legal remedy. Speaking for myself, it is largely a 50:50 on refunding and declining a deposit return. I have never had any legal issues with anyone, with most tenants who incurred a partial or zero refund agreeing that it is warranted when consulting the rental agreement they have read, understood, and signed. I, for one, will not be taken for a mug by argumentative tenants like you.
