In maintenance matters concerning minor children, findings of fact by the primary court will only be interfered with on appeal where there is a clear error of law or misdirection. A parent seeking to reduce maintenance obligations on grounds of changed financial circumstances must provide cogent evidence and details of such changes; bare averments are insufficient, particularly where there is a history of meeting those obligations in the same financial position. The best interests of the children, including their educational needs and special requirements, are the paramount consideration in determining maintenance obligations. Where one parent is the primary caregiver bearing the costs of day-to-day needs, and the other parent has demonstrated the capacity to pay specific expenses such as school fees, a court may properly order that parent to bear those costs entirely, notwithstanding claims of inability to pay that are not substantiated.
