Post-divorce house and partner?

I'm about to purchase a new house, but I have never been in a relationship. How do I go about setting things up in case of a future divorce? I live in NJ.<br><br>I'm a bit more worried since I'm less than 5 years away from being able to buy out my stake of a business, and I may make significantly more that the next 5 years. How do I protect it? Does a prenup solve everything?<br><br>Some background: I'm a first-generation American and my parents immigrated and didn't have a lot of money growing up. I didn't realize that the concept of prenups existed until a friend from a wealthy family got one. Any advice would be appreciated!
