Question juridique clé
Whether the reduced child-support contribution could take effect retroactively from the filing of the modification action despite later-born children
Solution extraite
The reduction could not be made retroactive to the filing date for the later-born children; the legal effect had to be staggered according to when the decisive family events occurred.
Motifs extraits
As a rule, modification takes effect at filing, but equity may justify a later date only where appropriate. When a new ground for modification arises only after filing, it is unjust to let its effects reach back to the filing date; the impact should be aligned with the respective later events.
