See Family Court Act §451(2)(a); Domestic Relations Law §236B(9)(b)(2)(i).
The ground: three years passed or a change in gross income

Check the ground that applies. Unless the parties have specifically agreed otherwise in a validly executed agreement or stipulation, three years have passed since the order was entered, last modified or adjusted. This ground only applies to original or modified support orders entered on or after October 13, 2010. Or unless the parties have specifically agreed otherwise in a validly executed agreement or stipulation, there has been a change in either party's gross income by fifteen percent or more since the order was entered, last modified or adjusted.

You are hereby applying for child support services from the Support Collection Unit (the IV-D program pursuant to Title 6-A of the Social Services Law) through the filing of this Petition, unless you check I have already applied for child support services from the Support Collection Unit, or I do not need to apply now because I have continued to receive child support services after the public assistance or care case, or foster care case, for my family has closed, or I do not wish to apply for child support services, or I am not eligible to apply for child support services because I am petitioning for spousal support only.
