My name is Aaron Freeman, an attorney in Indianapolis.
I'm very sorry to hear of your trouble.
Honestly, you should consult with a lawyer regarding your situation. There are laws that apply to marital property and with child custody issues. There are even laws that state before a married person can move a child to another state, that parent must provide the other parent with notice.
In short, you should work with a lawyer to go through the appropriate steps with going to court to get a temporary order for what should happen.
Best of luck!
If your interested, my office number is 317-951-0087
Sincerely
Aaron Freeman
