I think prenups are a good idea for those that already have a large amount of wealth before they're married. Though I'm not sure how effectual they are once kids etc come into the picture as isn't the family court free to set them aside and deliver their own judgement?
We're getting married tomorrow. My fiancée was more than happy to sign a pre-nup but I didn't bother.
A) We're staying together (yeah I know - everyone says that!
).
B) We're going to have kids straight away so pre-nups aren't worth much after that I believe.
C) She's been along with me for the ride supporting me for a large portion of the asset base I've now accumulated. Without her support it wouldn't be as large as it is now, so I feel she is entitled to a portion of it anyway.
D) For the next few years at least (until the marriage is well and truly ensconced with time and kids) the above asset base has a lot of debt with it, so there's not really much to take me for anyway.
