In the case of SPH v SA, the Court of Final Appeal in Hong Kong ruled that whilst the Court is not obliged to give effect to nuptial agreements, it should give weight to such agreements where it is fair to do so. In other words, nuptial agreements are not strictly binding in Hong Kong.
Such agreements would only carry weight if each party had entered into the agreement of his or her own free will, having all the material information and intending that it should be effective to govern the financial arrangements if their marriage comes to an end.
It is advisable for both parties to seek independent legal advice before entering into any nuptial agreements.
