“When determining what is unjust and inappropriate, courts, tasked with considering 17 factors, have various interpretations. In J.V. v. G.V., 11 the Supreme Court of Nassau County concluded that the presumptive award was unjust and inappropriate and reduced it by one-half, even though the payor husband earned in excess of $500,000. The facts of that case were somewhat unique.”

“Although rejecting the husband’s arguments that the wife had not pled with enough specificity or that her claim was barred by the statute of limitations, the court carefully examined the substantive issue presented, namely “whether [the wife’s] unilateral statement under oath is irrefutable, as [the wife] suggests, or if [the husband] is to be afforded the same procedural and substantive due process as is available for any other cause of action in our jurisprudence.”

“Since a person cannot be separated from his or her human capital (i.e. a person’s attainment of knowledge and skill, etc.) the way one can be separated from financial or other tangible assets, and given that human capital is not readily quantifiable, the courts are left in the unenviable position of adjudicating how to account for the attainment of human capital during a marriage.”

“After Wegman, trial and appellate courts, perhaps in an effort to create consistency and order, began categorizing assets as either “active” or “passive” and setting valuation dates based on this categorization-most often a date of commencement of the action for “active” assets, whose values are affected by the active participation of the title spouse, and a date of trial for “passive” assets, whose values are affected by outside influences such as inflation or market forces.”
