As a tenant it is your right to receive the security deposit from your previous landlord while you had vacated the rented apartment.
It should be noted that whenever a tenant notifies the landlord about his intent to make amendments in the tenancy contract or to serve a notice of vacating the rented premises, it is recommended that he submits his requests or notice in writing. Even though the tenant is not renewing his tenancy contract, it is his responsibility to serve 90 days of notice period to the landlord of his intention to vacate the rented premises.
This is in accordance with Article 14 of the Amended Dubai Rental Law, which states: “Unless otherwise agreed by the parties, if either party to the tenancy contract wishes to amend any of its terms in accordance with Article 13 of this law, that party must notify the other party of the same no less than 90 days prior to the date on which the tenancy contract expires.”
Based on the aforementioned provisions of law, you had notified your previous landlord verbally three months in advance regarding your intention to vacate the rented apartment and the same was mutually agreed by you and your previous landlord. Your previous landlord mentioned to you that there was no requirement of any formal notice of three months to be served by you, in writing.
