This whole thing is a bit surprisingly to me since it seems like Elon covered his bases with the separate property agreement. Yet it still has been a major hassle for him money wise.
Gene Simmons (from the band kiss) has an interesting approach to this which he wrote about in his book. He never married his long time partner and playboy playmate Shannon Tweed. But he took it even a step further having her and other live in girlfriends sign documents stating that despite living together they would not become common law married.
Trump is ok with marriage, but puts strong pre-numps in place.
Anyway, it's reading articles like this that can really turn you off to marriage as an entrepreneur. It's hard to say whether you're going to be in love with someone in 20 years, much less 1 year, so why put a legal contract on it? It might make more sense to vest your marriage over time or just take your partnership one day at a time without a contract.
The article suggests that the document was negotiated over a 3.5-month period, with the wedding occurring part-way through it. It's not unreasonable to claim that both parties went to the altar with a basic idea of what was going to be in the final draft.
Perhaps, but it's a different legal situation (at least at present) and plus we're getting Elon's side of the story now. We may be tempted to pick his side because he makes cool things but that doesn't make what he says true.
Which is why, honestly, outsiders should know as little as possible about these situations. We can't know what actually happens so why do we want to be in a situation to demonize one person and feel sorry for another based on this lack of information?
