I'll be in a similar position if I ever marry again too, and want to protect my current assets for the benefit of my kids. I won't have any more kids anyway, so any future wife can't claim that she needs child maintenance...etc, but if I did marry again, regardless of wether it was to a Brit/Pinay or anyone else, I would want them to know that they could only have half of what we had accumulated jointly since we got married...whatever I had before the marriage can't be taken into account
