Reese Witherspoon and Ryan Phillipe, Denise Richards and Charlie Sheen, Whitney and Bobby (but, then, who didn't see that one coming).  There are even rumors that Brangelina are on the rocks.

When these stellar couples began their highly publicized unions, it was all smiles and happiness.  But somewhere along the way, something went wrong and the bliss is over.

Imagine a breakup, but it is with a business partner.  It can get uglier than Britney Spears and Kevin Federline in court.

And a good deal of the heartache can be avoided by having clarity in your partnership agreement.

• Be clear on responsibilities of each party
• Outline how the profits are distributed
• Insure your partners to fund buy/sell agreements in the event of their death
• Outline how the partnership will end, if it comes to that

It's always a good idea to have legal representation when drawing up these agreements. 

By dealing with these issues up front, you can avoid potential trouble down the road.

And who wants to end up like Brit and K-Fed?
