In a reported (precedential) trial court decision, Martin v. Martin, released on July 31, 2009, Judge Haas, in Burlington County ruled that there no longer is an automatic review of child support every three years. Rather, for child support to be reviewed, the mere passage of time is not enough, and there has to be a showing of a change of circumstances.
The Court went on to point out that the three year review relates back to a prior version of a particular statute and has essentially been replaced by a Cost of Living Increase (COLA) every two years.
While this is an interesting opinion and makes logical sense, since it is a trial court opinion, other trial court judges are not required to follow it. Moreover, there is precedential decisional law that states that passage of time can be a change of circumstances as to child support because it is well known that as children get older, certain expenses increase.
