There are a lot of things to think about when starting a business, and that’s the understatement of the year. But as you court venture capitalists, read through office space leases and vet suppliers, there’s one more item you may want to consider adding to the ever-growing laundry list. Edouard LeFevre of Foley & Lardner suggests looking into a prenup between cofounders.

Whether you’re married to your business, or another human, these agreements can prevent litigation down the road, and govern what to do if personalities clash, creative visions differ or personal circumstances change, says LeFevre. “Without a prenup, the departure of a cofounder may lead to unfair results,” he explains.
