Respectfully request advice as newly divorced dad

Sorry to hear that you are going thru this. Having gone thru this before myself, I'll echo most everyone else's comments in here, get a lawyer. Ask your friends, interview a couple, find one that works for you, and tells you the real deal, not some happy bullshit. This is going to be a fight, and they will be doing the fighting for you so get someone that you can work with but also knows their ****. Any financial transaction you have with your ex wife needs to be via check, absolutely NO cash. Get your own account and start putting your paychecks in it. Don't take any money out of your current account but stop putting more in it. Use text or email to communicate as much as possible and screenshot your texts. Ask for your daughter as much as possible, even if you know you're not going to get her, ask for her. It establishes that she is withholding the child from you and that you are trying to maintain the relationship. Get as much custody as you can. Once you have it, it's harder to take it away. It's nearly impossible to get more once the orders are established.

Get a lawyer, take the day off if you need to, but get one ASAP. She's left and she's not coming back so at this point the fight is for your daughter, and the one that will help you the most make that happen is a good lawyer
