In custody disputes, the best interests of the child as required by section 81(2) of the Constitution are paramount and override parental preferences. Courts must apply the comprehensive factors in McCall v McCall including the parent's ability to provide economic security, educational wellbeing, emotional and psychological development, and environmental stability. A mother will not be deprived of custody without good cause, particularly where she has consistently provided care, stability, and all material needs. Access arrangements should facilitate the child's adjustment to the new reality of divorced parents and not create confusion. In determining maintenance, courts may draw adverse inferences from a parent's failure to fully disclose income and contradictory evidence regarding financial capacity. Under section 7 of the Matrimonial Causes Act, courts have broad discretion to make just and equitable orders regarding matrimonial property, including deferring complex matters involving foreign property and multiple creditors to competent foreign courts where parties are already before such courts.
