Thanks for your question. You have some real problems here. The money that you asked about can certainly be deposited in a joint account probably without signature. It will be put in as a deposit only.
I would advise you to take all the funds after it hits the joint account and transfer it out of the account to one in your name. He's really wrong about all these funds that he says are his, usually funds/income accrued during marriage are considered community or shared assets.
The problem is that once they get in a single account even if they are joint it's harder to get them released. You really should consider leaving this guy. He has no sense of sharing anything. If you have control of the $9,00 you describe at the worst someday a divorce court rules that you have to give him a portion back but then the other funds you describe may be refunded to you as well.
I wouldn't trust this guy in the least, he has misused you time and again. Your thinking about him getting the money is right. You got the check and you shoudl put it to your use andpay whatever you need to pay. I hope this gives you some ideas in this matter..
