Actually the person pays Rs. 5000 rent to the owner of the house for which he (tenant) gets rent receipt, irrespective of the fact the owner/landlady of the house is his (tenant's) wife or not, the owner of the house is a separate entity in accounting term, probably in Income Tax term as well.
There is no reason why an earning woman cannot have right to recover money from his client/tenant even if he is her husband. The nature of the landlady here dominates her role as wife.
