Free School Meals for Sixth Form student

Hello,I am in Year 12 and my parents are currently in the process of a divorce that has issues to do with DV so it is not like a peaceful process . Anyways , my mum has always been a stay at home wife who was employed by my dads business however of course now he does not pay her .My dad is currently unemployed however he has income from properties so he is not taking any benefits.So as the eldest daughter of an immigrant household I took it upon myself to ask if anyone knows that I can be eligible for free school meals or like pupil premium or any financial support . Thank you sm❤️
