In order to claim tax benefit of joint home loan , a person is also required to be joint owner of the property .

Eg- parent and child together take up a loan which is paid off by both of them. In such a case ,where child is not the co-owner is devoid of the tax benefits on the joint home loan

Need the reference of the above statement ,in which section it is written or any rule or notification?
