Before you utter "I Do!" -do sign up a pre-nuptial agreement. Though it's late for such an advice, but it's always better to be prepared for the next. It's always advisable to go for a pre-nuptial agreement, if one partner has more assets than the other before getting married. So even if the harmony of marriage comes to an end, it will not affect your bank balance. Divorce is eventually a wealth killer as it will rob off half of your wealth, ruining your secure retirement. So, the story comes with a simple moral: Carefully marry by signing a pre-nup if your spouse is richer than you.
