Buying property in joint name

There is typo in the question. I mean to say co-owner and not co-borrower.

yes if he is made coowner and if he dies intestate then his share in the pro[erty will devolve equally over his class 1 heirs

Thanks for your reply. But he is not going to make any payment in the said purchase.

All the payment will be made by me. In such case is it still possible that his class1 heirs will have right on the property?

yes just because he is a coowner of the property along with you and he has rights over his half share in the property

Thanks for your valuable inputs. If he is just a co-applicant for applying for home loan and not a

co-owner then  is it still possible that his class1 heirs will have right on the property?

no if he is a coapplicant to the loan

Why at all you want to complicate things which may go against you in future.  Even is he made co-applicant, his legal heirs  may start a litigation seeking a share in the property upon his intestate death, no doubt you may win but it may take several years even a decade to settle the issue, hence if you are financing yourself, better let the property as well as the loan account be on your name alone.  Think wisely.
