Respectfully request advice as newly divorced dad

Sorry to hear what you are going through, been there done that. WASTED tons of money of effin Lawyers.
Best advice is for you to check the LAWS in your state, secondly if you are still talking and can come to an AGREEMENT you will be way ahead of the game. If you BOTH agree to it, put it in writing and present it to the JUDGE will gladly sign in and send you on your way out of his court and you are DONE.
