An increasing number of couples enter into a private maintenance payment agreement instead of applying for NAV to determine the child support payments. Providing support to children is a private matter between the parents. It is not necessary to involve or inform NAV if you can reach an agreement in which both are satisfied. The exeption is if the parents were not living together at the time of the child’s birth.

The agreement should be in writing and is as binding as an administrative decision. If you want, you may use a standard agreement available under Forms in the menu option. This can provide a framework for the agreement.

By entering into a private agreement, you do not have to paya fee to NAV. The fee is 860 kr.

Child support calculator

You may use NAV’s child support calculator (only available in norwegian) as a guide. Based on the information you provide about the parties in the case, the child support payment is calculated in the same way as it would have been determined by NAV. When NAV determines the child support payment, it is based on applicable legislation. Your personal circumstances, income and how much time each parent spends with the child, are taken into account.

In a private agreement, you are free to agree on a regular amount and to adjust it according to your personal circumstances. The amount may be altered according to how it suits you and if there are changes in personal circumstances.

Payment of the child maintenance

Although the agreement is private, you may decide to have the maintenance payments collected and forwarded by NAV. You must then submit an agreement together with an application for collection of child support payments. Collection by NAV is free of charge.

If you would like to arrange transfer of the maintenance payments without involving NAV, you may do so. This depends on whether you have entered into a private agreement or not.

Note that if the custodial parent receives advanced support payment, the child support must be administered by NAV.

If you have agreed on a child support payment which is lower than the amount paid in advance in the case, NAV may alter the child support payment. This is because NAV shall be reimbursed from the child support payments for the advance maintenance payments it has paid.
