Joint custody for shared children

In the case of a breakup of a relationship, the parents can decide what kind of housing arrangement they want for their children: joint custody or custody.

Both parents’ addresses can be registered in the National Population Register, but the child can only have one residential address. To make sure that the child’s residential address is registered correctly, it’s important that the custody arrangement is registered in the National Population Register.

Custody means that the child lives with one parent and has a visitation arrangement with the other parent. Joint custody means that the child lives (has a permanent place of residence) with both parents. The parents themselves decide how much time the child will live with each of them, and they must agree on which address will be the child’s residential address.

We recommend that you use Bufdir’s Foreldresamarbeidsavtale – an agreement regarding shared permanent housing to prepare a parental cooperation agreement:

  • The agreement must be signed by both parents.
  • You must attach a copy of valid identification from both parents.
  • Send the signed agreement to us at:
    Skatteetaten
    Postboks 9200 – Grønland
    0134 OSLO

Agreements sent online only require an attached identity document from the parent who is not submitting the agreement.

Requirements for registration of joint custody for children

  • Both parents must be registered in the National Population Register.
  • The child’s/children’s residential address must be at one of the parent’s addresses.
  • The child/children must be under 18.
  • The parents must have joint parental responsibility.

Report a move for the child

The parent or parents with the parental responsibility can report a move for the child if the child shares his or her address at the time of the notification of the move. When an agreement of joint custody has been registered in the National Population Register, both parents must consent to the child’s move in order for the notification to be valid.*

The parents can agree to a change in the child’s address in the National Population Register by entering into an agreement on joint custody. This is not considered a move, and it does not automatically lead to an address change for the child in the National Population Register. The parents must report a move for the child to the agreed address.
