Can a Housing Deed be entered with Retrospective Effect and can HRA be claimed on the same for the retrospective period ?

For Example : The Tenant enters into a contract with the Land lord on Jan 2019 stating that the the lease has been executed from the period of April 1st 2018 for a period of 11 months, for a monthly rent of RS.9,000. Can he claim HRA Deduction for the same from April 2018 or Jan 2019 ?
