How do I stop my husband from leaving me with no way to financially maintain household after he filed for divorce.

My husband moved out after years of destroying our marriage, he closed a joint checking account removing all the money, stopped his direct deposit from our other two joint accounts, and filed for divorce obtaining a mutual asset restraint injunction. I am a stay at home wife, we have been together for 21 years, but only married for 7. Our daughter is now 20, and we are full permanent guardians of four minor grandchildren. He had been allowing me access to half of his income, but as of today, he put a stop to the direct deposits completely and says he will deposit what he feels I need for groceries and living expenses. He states he will only be paying the rent, water, gas, and electricity. I will not have access to funds to secure legal representation.
