Where a child is born is very significant, in terms of what state has jurisdiction over the child, esp if an interstate custody dispute should arise. Pursuant to the Uniform Child Custody Enforcement laws, where the child is born and lives for the first six months of it’s life is the state that has jurisdiction to determine custody issues, unless the child is over 6 months of age and has established residency in another state. Another factor that would affect what state has jurisdiction is whether the child is born in or out of wedlock, to a single mother or a married couple.
Generally, if you are a single mother, and want State X to be the home state of the child, you should give birth there, and stay there with the child for at least six months. A brief visit to another state will not interfere unduly with the state’s right to jurisdiction; however if you there is no clear cut domicile and residency for the child within its first year, the court will look to broader issues such as where have the parents resided for the better part and what kind of ties to the community a child has with any of the states at issue. Further if you removed yourself with the child in utero, without consent of the father/husband you are looking at a more complicated legal situation.
If the father is an MA resident and is adamant about the child remaining in MA, you may have a problem if you have not clearly established the child as born and resident in the state of your choice, and the MA court may require you to return the child to MA. The less stable the child’s identity with another state, the more likely MA will find jurisdiction to award or determine any custody issues.
As always, I must advise anyone considering relocating to give birth to consult with an attorney.
