Your Business Partnership Agreement Is Basically a Prenup for Your Business (And You Need One)

Nobody gets into a business partnership planning for it to fall apart. Same goes for marriage, and yet prenups exist for a reason. "We'll figure it out if something goes wrong" is not a plan. It's a hope, and, sorry to be the bearer of bad news, hope is not a legal strategy.

If you're going into business with a partner — a co-founder, a friend, your cousin who's "really good with numbers" — a solid partnership agreement (or operating agreement for an LLC or shareholders agreement for a corporation) is the business equivalent of a prenup. It's not a sign you don't trust each other. It's a sign you both care enough about the business to protect it.

And here's the thing about starting a business with someone: the early days are the honeymoon phase. Everyone's excited, everyone's aligned, everyone's saying things like "we'll never let money come between us." Cute. But two years in, when the business is actually making money (or actually struggling), those good vibes don't hold up the way a signed agreement does.

I get why people skip this step. It feels like planning for a fight before you've even had one. But a partnership agreement isn't about assuming the worst. It's about making sure the best version of your business survives whatever comes next, whether that's rapid growth, a slow season, or one partner deciding they want out.

Here's what that agreement should actually cover.

Who Owns What and How Much 

Ownership percentages seem obvious at the start. One of you put in more cash, the other put in more sweat equity, and you shook hands on a number that felt fair at the time. Get it in writing. Include how ownership can change over time (through additional investment, buyouts, or new partners joining), because "we agreed on this two years ago" is a lot weaker than a signed document.

This is also where you'll want to define what counts as a contribution in the first place. Cash is easy to measure. "I handled all the client calls for the first year" is a lot harder to put a number on after the fact, so put a value on it now, while both of you still remember and agree on what everyone brought to the table.

Roles and Decision Making

Who has final say on hiring? On spending? On whether you take that huge client who's a total nightmare but pays well? Spell it out now, while everyone's getting along, instead of during a heated group text later. Decide which decisions need unanimous agreement and which ones one partner can make solo.

This matters even more when partners have different day-to-day roles. Maybe one of you handles the creative side and the other handles operations. Great, but what happens when the creative partner wants to spend money on a rebrand and the operations partner thinks it's a bad idea? Your agreement should set a clear process (and a dollar threshold, if it's relevant) for when a decision needs both partners' sign-off versus when it doesn't.

Money In, Money Out 

How are profits split? How are losses handled? What happens if the business needs more cash and one partner can't (or won't) contribute? These are uncomfortable questions to ask a friend or family member. They're a lot more comfortable to ask now than after a slow month has everyone pointing fingers.

Also worth addressing: salaries. If one or both of you are drawing a paycheck from the business, decide now how that's determined and how often it can change. "We'll figure out pay once we're profitable" tends to turn into an argument about what "profitable" even means, and by then, everyone has a different definition that happens to favor them.

The Exit Plan 

This is the part people skip, and it's the part that matters most. What happens if a partner wants out? What happens if a partner passes away, gets divorced, or just stops showing up? A good agreement includes a buyout process, a valuation method for the business, and a timeline for how it all plays out. Without this, a partner leaving can turn into a legal fight that drains your time, money, and sanity.

Think about the range of exits, too, not just the dramatic ones. Someone might want to leave because they're burned out. Someone might get a job offer they can't turn down. Someone might want to reduce to a part-time role instead of leaving completely. Your agreement doesn't have to predict every scenario, but it should give you a framework for handling whichever one shows up.

What Happens If You Just…Disagree

Not every disagreement needs a lawyer. But some do, and your agreement should say what happens when you're stuck: good faith negotiations first, mediation next, and then (worst case) court. Deciding this in advance means you're not negotiating the rules of the fight once you're in it.

Legal tip: A verbal agreement or a handshake is not a partnership agreement, no matter how good your handshake is. Courts want documentation, and "we always meant to write it down" doesn't hold up when things get contentious.
