1. In custody matters, the best interests of the child is the paramount consideration, not the biological relationship or gender of the parent. Parental roles are social constructs, not determined by anatomical constitution. A parent who is unavailable due to work commitments and leaves a child with domestic help, resulting in deteriorating school performance and lack of proper supervision, may not be the appropriate custodian even if the biological mother. 2. Acquiescence to a postnuptial agreement is established when a party's conduct leaves no reasonable doubt as to their intention to be bound by its terms. Conduct such as paying legal fees to implement the agreement, participating in discussions about its execution, complying with its terms, and only disputing specific provisions while accepting others, constitutes binding acquiescence. 3. Under the Takafuma principle and section 7 of the Matrimonial Causes Act, property acquired by one spouse individually during a period of separation using their own funds, without contribution from the other spouse, falls into the separate estate ('his' or 'hers' basket) and should not be redistributed absent justification under section 7 factors. 4. A parent lacks locus standi to claim maintenance on behalf of an adult child. Furthermore, a parent who unilaterally makes educational decisions for a child (including sending them abroad) without the knowledge or consent of the other parent cannot compel that parent to fund such decisions, particularly when the educational institution is demonstrably inferior to available local alternatives.
