Legal Question in Family Law in Maryland

Re: where do I go for custody of my daughter?

Jurisdiction over a child is usually where the child resides. In your case the Child resides in Maryland, therefore you will need a Maryland lawyer.

Re: where do i go?

If the current custody status comes out of a court order, such as the divorce decree, you'll probably have to go back to the state that issued that order, unless it's neither MD or NJ. In that case, you can file in either state. From a practical standpoint, the court will want to conduct an investigation, which will consist of assigning a court social services worker to do "home visits" at both locations to see whose situation is best for your daughter. Whichever court takes jurisdiction will coordinate with the "sister" agency in the other location for this purpose. Bear in mind that courts are reluctant to change custody unless there's a compelling reason to do so.
