There is no cost for requesting a modification through the child support office.
After reviewing the information (above) you and the other parent provide, the child support office determines whether the existing order meets modification requirements.
If the requirements for a modification are met, the child support office prepares legal documents, has them reviewed by the County Attorney's Office, and mails them to the parents. If neither parent responds, a court order is prepared and sent to the court. If one or both parents disagree with what is proposed, you will receive a notice to appear in court for a hearing where a Judge will decide the amount.
Your child support order can go up or down based on the information gathered. The new court order may not be what you expected.
If you and the other parent can agree to the support amount ahead of time, the child support office can prepare the agreement and file it with the court.
If the requirements for a modification are not met, the child support office notifies the parent who requested the review. If the parent disagrees with the child support office's determination and still wants a modification, they can file a motion asking the court to modify the order. There may be fees charged for this.
If the other parent lives in another state, the child support office may have to request that the other state conduct a review and request a modification.
