I would therefore argue that by focussing on what is essentially a practical impossibility for the previous non-residential or non-custodial parent to prove his increased
costs simply
upon reaching the 40 per
cent threshold (as opposed to recognizing that parent's fixed and discretionary
costs of exercising access or joint custody), both the Court and the Guidelines themselves are unfortunately perpetuating what may very well be a most unjust treatment
of children in one parent's household.
