The law looks at which child(ren) had the support obligation reduced to a legal agreement or court order of suppot first, and that child then has priority over any later or prior born children who did not get such recognition. In other words, if a court ordered support for the first two children, the birth of the third to the payor parent does he no good in reducting her obligation to the first two children. Distinct from that is the loss of her job, which if occuring through no fault of her own, does reduce the amount of child support as a legitimate reduction of her income and the application of the 25% on a small sum will result in a smaller amount of support.

I'm a bit confused by the timing here, but if she is granted a reduction in her support obligation, it will be retroactive to the dare of her filing of that petition. However, any arrears which accumulated up to the date of petition filing will still be owed to you. Is that what you were asking?
