If a landlord does not return a tenant's damage deposit in 15 days from the later of the move out date or receiving a forwarding address, tenant may go after him for double. If the forwarding address for mail is provided in e-mail or by a messaging app (such as Whatsapp, which has read receipts) is this enough? Or must the tenant use registered mail and then wait 15 days?
