Since all Co -Owners are eligible to claim interest individually, interest will be allowed according to your share in the property in your case 1/3 each.
As the EMI is paid by you and your father, do get a declaration from your mother that the you both will pay the EMI for the entire loan, and she will not claim any benefits on interest against her share. Since the act allows to carryforward the loss on house property resulting by way of interest claims in case of self occupied property for each co-owners.
