Taking Assistance Through Zakaat to Pay Expenses

Q: I earn a salary of R13000.00 and I have seven children. Alhamdulillah, my expenses of rental, lights and water, maid, school fees, an interest free loan that I took to buy a car and petrol add up to R8700.00 which doesn’t leave us much for Food, nappies, clothing and medical. Am I justified in approaching someone for a monthly assistance in the form of zakaat to pay either my rental or lights and water? Neither my wife nor I own any gold or jewellery. A flat that my mother is presently occupying will only become mine after her demise, may Allah grant her long life, aameen. My father left property in India for us but I do not possess the means or the knowhow of acquiring this.
