Don't make me destroy you
If this business law lark has taught me anything its don't go into partnership with anyone you don't know inside out and for the love of cookies and miniature piglets get a written agreement of whats supposed to happen in the partnership before you start!
I forgot to post that. JZ UK is speaking the truth. You've got to have a lot of trust between yourself and you're partner. If this person has owned other businesses before, look at that history. Don't be turned off by failure though. There is nothing wrong with failure. Find out why it happened, if they indeed failed before. Were they careless or did they take every precaution? Did the environment change? Did a partner screw them over? Have they operated ten successful businesses?
