Am I religiously obligated to pay my father's water, gas, and electricity bills, given that he has not asked me to and I live in an apartment he owns?

If the questioner is able to pay for electricity and gas, she should pay for them, unless her father forgives her; because her maintenance and the maintenance of her two daughters are not obligatory upon him due to her possessing wealth, and because the maintenance of her two daughters is obligatory upon her as she relinquished them in exchange for the divorce. She should ask her father if he is content with paying those costs, otherwise, she should install two separate meters for electricity and gas for her own use.
