You probably realised their university education will set you back a hefty amount, but have you considered the expense of sending them to an international school right from primary age up to University?
Their future is in your hands, which is why it is so important to plan ahead. From their first steps, to the time they are financially independent, you will never stop wanting the best for them. And you will need to plan for every step of their education and beyond.
And of course later in life when you pass away, having peace of mind that your nearest and dearest will be financially secure and your estate is passed on as smoothly as possible is invaluable.
