HRA Query

I stay on rent with lease agreement in my sole name. I used to pay the rent by cheque and claim tax break on HRA (with lease agreement as proof of rent). However, my wife has recently started working and now pays part of the rent (by cheque) while I pay the balance (by cheque). My land lord refuses to give a rent receipt in my wife's name citing that lease agreement is in my name. 

The question is can my wife still go ahead and claim HRA tax break by submitting : a) a copy of the cheque payment to landlord and b) a copy of the rent agreement (which is in my sole name)
