Where can I file for custody? (Which state has jurisdiction?)
Custody jurisdiction is state law. However, Connecticut, like most states, has adopted the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), which we explain here.
Under the UCCJEA, you can only file for custody in the "home state" of the child. (There are exceptions to the "home state" rule -- see below.)
The "home state" is the state where the child has lived with a parent or a person acting as a parent for at least six consecutive months. If your child is less than six months old, the "home state" is the state where the child has lived from birth. (Temporary absence from the state does not change anything.)
If you and your child recently moved to a new state, you cannot file for custody in that new state until you have lived there for at least six months. Until then, the other parent can start a custody action in the state that your children most recently lived in for at least six months.
There are exceptions to the home state rule. In some cases, you can file for custody in a state where the children and at least one parent have "significant connections." Usually, however, you can only do this if there is no home state or if the home state has agreed to let another state have jurisdiction. This can be complicated, and if you think this applies to your situation, please talk to a lawyer in both states about this.
You can also file for temporary emergency custody in a state other than the home state if:
1. the child is present in that state, and
2. the child has been abandoned or it is necessary in an emergency to protect the child because the child, or a sibling or parent of the child, is subjected to or threatened with mistreatment or abuse.1
