Every family business has a version of this scene. Two brothers, co-owners, standing in the shop. A supplier is at the counter, or a customer, or the one good employee they cannot afford to lose. And an argument that started at home, or started twenty years ago, chooses this exact moment to surface. Voices rise. The customer studies the floor. The employee updates his resume in his head. The brothers will make peace by Sunday, because they always do, but the customer will tell the story for years, and the story is not about the argument. The story is that the business is the family's mood, wearing a signboard.
One family got tired of that scene and did something almost no family does: they wrote down the rule. In plain words, in a shared document, they committed themselves to fight about it privately, never in front of anyone the enterprise serves. Their rule, and the remarkable document around it, is preserved in Dennis T. Jaffe's Borrowed from Your Grandchildren: The Evolution of 100-Year Family Enterprises (Wiley, 2020), a six-year study in which Jaffe's research team interviewed leaders from just over one hundred family enterprises worldwide, each with at least two generational transitions behind it, more than $250 million in current revenue, and a family identity still intact. He calls them generative families and reckons fewer than 1 percent of family enterprises ever qualify. Be clear about what that means for us: this is a study of very large, mostly North American and European fortunes, with no African family in the sample. The structures they use are mostly out of reach. The sentences they wrote down are not, and this essay is about the sentences.
The family behind the rule was not a calm one. Jaffe introduces them as a third generation of several siblings carrying "a family legacy of lots of conflict and rivalry across genders and those working in and out of the business," who noticed, with alarm, that the pattern was passing to their children. They did not hire a therapist for the whole clan or write a mission statement full of soft words. They convened a task force and drafted what they called a Code of Behavior, a list of standards family members agree to aspire to when they deal with each other. Jaffe is careful to report the result honestly, and so will we: "This code did not end conflict, but it set some useful and practical standards of behavior that they could challenge each other to follow."
Three of its lines are worth quoting exactly, because you could post them on a wall tomorrow. The first is the client rule: "We strive to address family, and family business conflicts privately and not argue in front of a client, employee, customer, or advisor." The second is a discipline for the argument itself. When a conflict needs a meeting, they arrange one, set a date and a time limit, and then, in the code's words, "use equal timed speaking turns with listener remaining silent," each person reflecting back what they heard before taking their own turn. The third is the rule that kills the slow poison every family knows: "We never want to speak negatively about anyone behind their back, but rather speak directly to the person we are at issue with."
Read those three together and notice what they have in common. None of them pretends the family will stop fighting. All of them assume the fight and route it: away from the audience, into a room with a clock, toward the person concerned instead of around them. This is not the language of harmony. It is the language of plumbing. The code even anticipates its own failure, instructing members that when tempers rise they should "take a break until we can remain calm and work towards resolution once more." These are rules written by people who know exactly what they are like on a bad day, written on a good day, for the bad one.
The Code of Behavior did not float alone. It lived inside a family constitution, and here Jaffe's study delivers one of its most striking findings. More than 80 percent of the families in his study have a formal constitution, and the rest have similar guiding agreements; the document most often first emerges in the third generation, right around the time the family stops fitting in one room. Hold the honesty note as always: that percentage describes one hundred huge, mostly Western families who agreed to be studied, not family business in general. But the pattern is hard to dismiss. Nearly every family that survived a century on purpose eventually wrote itself down.
And here is the part that changes what kind of document you should imagine. These constitutions are, in Jaffe's words, "not legal documents, though like such agreements, they are written, agreed to, and signed. They are often referred to as moral agreements, in that family members voluntarily agree to them because they care about each other." No court enforces a family constitution. Its entire force comes from the signature being voluntary and the signers being people who must face each other at every holiday for the rest of their lives. A lawyer would call that weak. The families call it the point. A rule you follow because you were forced teaches compliance. A rule you follow because you signed it in front of your siblings teaches character.
The cost is real, and Jaffe's interviewees do not hide it. One family member describes the drafting: "I joined the working group called a family council task force. We would sit together and go over the examples of other family constitutions. We met every month for a year and a half to discuss the different policies and outline. It was a lot of discussion and debate." A year and a half of monthly meetings, for a document with no legal force. That is not bureaucracy. That is a family paying, in its scarcest currency, attention, for an agreement everyone will actually honor, because everyone was actually heard.
The obvious objection deserves an answer. Everyone already knows you should not fight in front of a customer. Everyone already knows gossip corrodes. Why write down the obvious?
Because the rules are not for the days when everyone knows. They are for the days when people forget their better instincts, and every family has those days. The moment the argument breaks out in the shop is precisely the moment no one is consulting their values. What a written code changes is not the fighters but the bystanders: it gives the cousin standing nearby a licensed, neutral sentence. Not "you two are embarrassing us," which takes a side, but "code, brothers, not in front of the client," which takes no side at all. The code turns an accusation into a citation. Jaffe's family understood this: the standards existed so members "could challenge each other to follow" them. A written rule is a tool handed to the calmest person in the room, and there is always one.
There is a second reason, quieter and more important for families that span generations. An unwritten rule dies with the generation that practiced it. The founder's discipline about never shaming a brother in public was real, but if it lived only in his conduct, his grandchildren inherit the business without it. Write it down and it becomes teachable. The book stops here, at the writing. We go one step further: the writing is also the argument's memorial. Fifty years on, a descendant reading "we never want to speak negatively about anyone behind their back" knows, without being told, that this family once bled from exactly that wound. A code of behavior is a scar map, and scar maps keep the young from walking into the same knives.
Now the translation, ours alone, for the family this essay is really for: the diaspora family running an enterprise across time zones. A sister in London and a brother in Houston funding a transport business their cousin manages in Kampala. A family investment group with members in three countries and a WhatsApp group where all of it happens. For a family with something to build together and an ocean in the middle, sharing a code is not optional politeness. It is load-bearing, because distance strips out every soft signal that keeps arguments human. Text has no tone. Voice notes cannot be interrupted for clarification. And the "shop floor" where the family must never fight is now digital: the group chat that includes the site foreman, the thread where the tenants are copied, the call where the supplier is listening. In a diaspora enterprise, "not in front of the client" mostly means "not in that group."
So write your own one-page code, and write it the way the study family did: while calm, together, and as a moral agreement everyone signs rather than paperwork anyone imposes. Adapt their lines to your reality. A starter version, to be argued over and made your own:
Notice that last line is not in Jaffe's code. It is our addition, because in families moving money across borders through mobile wallets and cash handovers, half the ugliest fights are really bookkeeping gaps wearing the costume of betrayal. A code for a scattered family must govern the ledger as well as the tongue.
Keep the finished page somewhere it cannot be lost in a scroll. The Family Council module in LegacyPot is built for exactly this: a place where the family's code lives alongside its meeting dates and minutes, visible to every signer on every continent, so the standard survives the phone it was typed on.
Here is the one thing to do this month. Open a document, share it with the family members who own or fund whatever you are building together, and draft your code of behavior: five to ten sentences, starting from the three rules the study family wrote, adapted to your channels and your history. Then schedule one call to argue about it. Set a time limit. Use equal turns. Expect the drafting to surface the very conflicts the code exists to manage; that is not the process failing, that is the process working, on a day calm enough to survive it. When the words are agreed, have everyone say yes on the record, and treat that yes the way Jaffe's families treat theirs: as a promise made because you care about each other, which is the only enforcement a family ever really has.
You will still fight. The study family still fought. But the fight will happen in the right room, with a clock running, facing the right person. And the customer at the counter, the employee within earshot, the in-law reading the group chat, will see what a hundred-year family looks like from the outside: not a family without conflict, but a family whose conflict has manners.
