I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear about your situation.
Until there is a court order, there are no laws that govern what a married couple must do with their money. In a divorce or legal separation, a judge will split all marital assets 50/50 and will decide how much your husband should be paying in child support based on that total income. But you have to specifically get a court order for that first. There is no law that says spouses must deposit their paychecks into a joint account, or that the higher earning spouse must share with the lower earning spouse in any way. Most people don't want that level of government intrusion into their lives.
You do have the ability to file for child support, and it's possible a judge will order him to pay more than $1,400/month for two children. This worksheet will help you figure out what he should be paying.
You could also seek an order granting you alimony pending lite, which means "pending litigation." Any local attorney could help you with that. There aren't free court forms to help a spouse seek alimony during the separation period. But you unfortunately do have to go to court before you'll be able to insist upon receiving your share of the marital assets and his income.
