Find a lawer

He could transfer the money from his acount to his relatives before you file a dissolution of marriage. I suggest that you try to get a copy of his current bank statement. Then talk to a lawer, who will know how to "freeze" his all accounts.

Since his income is higher, you should get some money after paying your lawer. In addition, why do not you request your spouse support? This does not make any sense in US. Do not be silly, nobody respects you on this.

Good luck
