In some cases the FOC is required to periodically review child support provisions (including health care) and file a motion for a change in the order if a change is warranted. When reviewing support, the FOC office may request information from a parent's employer, including the parent's address, social security number, date of birth, wages earned, and dependant health care coverage available as a benefit of employment.

If ordered by the court, the FOC will conduct a financial investigation and make a written report and recommendation to the parties and the court regarding child support. FOC reports cannot be used as evidence in court without the agreement of both parties. However, the FOC investigator may be called as a witness to testify about the report and recommendation. The Judge may read the report whether or not the parties agree.
