100% housing loan claim by co applicant who is paying full EMI for joint loans

I would like to add to the above reply that, since in the above case the entire funding for the property is borne by you and your wife is not paying anything, there can be an argument that you can claim the entire 100%. There are case laws wherein it is held that merely because the property is held jointly although the payment/funding is done by one joint-holder, full proportion of deduction can be taken.

Kindly check the relevant jurisdictional verdicts on similar facts as applicable to you.
