Hello and welcome,
There is no set number of months before a modification may be requested normally, but a showing of material change in circumstances is required.
A petition to modify the child support order may be filed by either party to a support action if a material change in circumstances has taken place typically. One example of a material change is the loss or change of income or employment by either party. The Domestic Relations Section (DRS) of the county court is responsible for determining whether or not a material change in circumstances has occurred. To file a Modification Petition, contact the DRS that manages your case, and request a petition for modification, complete the petition and return it to the DRS. The DRS will advise you of its determination and if and when a hearing will occur.
