1. A prenuptial agreement outlines what belongs to who entering into the marriage, thus making it clear to both parties during the marriage which things belong to who.
2. Getting a prenuptial agreement can be a great educational experience. It teaches you all about what you are getting into as you approach your upcoming marriage. Or, for a post-nup, it teaches you the status of all of your property. Many people don't realize that in California all income after marriage belongs to both parties equally. If you get a prenup, you will have more knowledge!
3. It's a practical gift that is still in the spirit of love! Some people struggle finding that right gift that is in the spirit of Valentines day that is still practical. A prenup is all about love and marriage, yet it's also practical, as it outlines the roles of both parties in the marriage. What could be better?
4. In all seriousness, a prenup can help lessen any potential future heartbreak, by making the divorce process simpler and easier. So, you could be (but hopefully not!) saving yourself from sad future Valentine's days.
