Dear Kunal Co-applicant is a person who applies along with the borrower for a loan. A coborrower along with the primary borrower accepts responsibilityfor repaying a debt. Since co-owners of a property should necessarily be co-applicants , one can include spouse as a co-applicant for aloan.Co-borrowers need not necessarily be co-owners but it is advisable to have a co-owner, as it takes care of any succession issues that could come up in case of the demise of one of the owners. You both will be the joint owners as your mother has contibuted 20% and you are borrowing 80% of the total cost from the bank as home loan. You are responsible for paying the loan and when you will not be in the position of paying for the loan, your mother has to pay the EMI's. Therefore,to some extent your mother will have edge over you in this property.Whoever is on the loan is responsible for the payment each month. If a payment is missed, both parties are penalized. However if the payments are on time each month, the credit reports of both borrowers will benefit. Rutumbhara www.lawkonect.com 09555 507 507
