The New Jersey judiciary says it has identified and removed a glitch in the software used to calculate child support, which in some cases inflated the amount to be paid, and is trying to figure out how many incorrect support orders were issued.

The Family Part was alerted to the flaw by matrimonial lawyer Robert Rottkamp, of Rottkamp & Flacks in Trenton, who learned his client’s obligation had been set too high after checking it with his own calculator program.
