Mortgage Loan

Yes, you can take loan by mortgaging your family property provided your father agree for that.

you can't mortgaged without your father's concern.

In that case you can get the loan amount but liability of repayment of loan will be of your father and not you. That to it is the sole discretion of the bank/ financial institution granting loan upon your mortgaged item subject to their rules and condition.

No sir you cannot mortgage that property unless you have ownership in that property
