1. In custody disputes, the best interests of the child are paramount and must be determined on the facts of each case, considering factors including the child's preference, the parent's ability to provide physical and emotional care, educational support, and the stability of the environment. The presumption that young female children are better placed with their mother can be rebutted by evidence. 2. Under section 7 of the Matrimonial Causes Act, matrimonial property division requires the court to: (a) categorize property as "his", "hers" or "theirs"; (b) apportion jointly owned property using the criteria in section 7(3); (c) consider the overall result to ensure it is reasonable, practical and just; (d) focus more on meeting the needs of both parties rather than strictly recouping contributions; and (e) consider all assets owned by each party to avoid inequitable overall distribution. 3. Property registered in joint names conveys real rights of ownership on both parties as a matter of substance. 4. Claims for reimbursement of financial assistance given during marriage require clear evidence of an undertaking to repay; spousal assistance during marital difficulties is presumed to be gratuitous absent proof to the contrary.
