Help on Income tax: Joint Loan/Co-owner. let out property..

Friends,  Please advice on how much Interest on house loan and Principal amount can be considered here.

1. Second Aprt.  Registered in Oct 2012.
2. Co-owner and Joint Home Loan. between myself and my husband.
3. Paid 1.46L as Interest and 46K as Principal this financial year.
4. No rental income yet.
5. We can assume 50%:50% share even though no where writen explicitly.

For income tax purpose,  myself and my husband can we both claim 1.46 L as Interest on Home Loan and 46K as Principal amount or we should just considered 73K ( 50% ) as Interest on Home Loan and 23k as Principal Amount

Thanks
