I don’t know about your state. Hire an attorney. File for the custody you want. You can reside close or even over 100+ miles away with your child. Being that your family is there and you want to be closer to family is fine. They’ll set up custody with arrangements. If it’s over 100 miles the non custodial parent will have longer visitations vs the state standards if you lived closer.

Make sure you’re detailed and specific! That helped me when I had to go back to court. I moved out of state and I made sure the arrangements were detailed. Like they had to text my number 2 weeks prior to meeting to let me know they wanted to meet (it’s a 4 hour drive halfway) I had to reply to said message. They also had to text again within 24 hours to notify me they still wanted to meet (things can happen) and I would have to reply to meet them at a designated public place. We asked to meet at a police station they asked for McDonald’s in the halfway point town.

Make sure that everytime you go to meet, walk into the nearest public place and buy something to have a receipt of the time stamp and place incase he doesn’t show, you have legal proof you were there.
Also make sure you put who can meet you and pick up and drop off y’all’s child. In Texas the standard is the parent can designate WHOEVER they want no questions asked! I didn’t know back in 2008 that I could request it to just be him and what not.

That’s why I say details details details. Depending on how old the child is we had zoom calls set up once a week at a certain time that my ex or his family could call.
It was stated that he had to buy our son a phone to communicate respectfully if I didn’t have a phone for him.
Also state that when your child is in his custody that you’re allowed to call and speak to your child too. I’ve seen a lot of families where the other parent wouldn’t allow the parent to call and talk to their kid while in their custody.

It sucks but it’s better to be detailed because things can change and happen over the years and I wish I would’ve been more throughout with my divorce case.
Also I noticed you mentioned child support. I’m not sure if it’s all states but most you can deny child support but others it’s mandatory and they’ll go after the non custodial parent for child support. Either you or him can set it up with your Attorney General but sometimes it’ll be automatically set up in a divorce case. Definitely ask your attorney.
