Corporate Financier's Notes ISSUE 029  ·  5 NOVEMBER 2026

Unlike the original, a family constitution binds no one on its own, and transfers no wealth. It records what the family wants, and how.

One Argument

A family constitution is a brief for the lawyers and tax advisers who build the transfer.

The publishers of a new German study call it a morally binding family agreement, intended as the basis for articles of association, board rules and wills.

The constitution’s job is upstream. It settles who may own, how profits flow and how someone leaves. The lawyer then drafts the articles and the shareholders’ agreement. Without that brief, the experts build on guesses, or on the views of whoever happens to be in the room.

The German study, by INTES Akademie, PwC Germany and the Digital Business University in July 2026, found that 36% of family firms have a constitution, up from 25% in 2011. Of those families, 78% used external advisers to write it, the kind of service the study’s publishers sell. Even then, 30% want to revise their profit-distribution rules, and 26% their rules on a shareholder leaving. For families without a constitution, the gaps are even wider — 53% say their emergency-succession arrangements need work.

Policy points the same way. The European Commission’s new, non-binding recommendation on business transfers, issued in June, encourages Member States to give more weight to what owners have agreed upon among themselves when an inheritance disrupts a business. The direction favours intentions that are already written into binding company documents.

The German study’s own authors argue that the joint drafting process matters more than the finished text. It forces owners to put their expectations, interests and roles on the table. Their data is consistent with that. Families with a constitution report stronger cohesion (72%), better governance structures (66%) and more stability (61%). They are also far more likely to prepare the next generation — nearly 40% have a plan for readying future shareholders, against 7% of families without one.

Only 29% of German families with a constitution report greater economic success. And the authors themselves infer no direct economic effect. But cohesion is tested at a death, an exit or in a bad year, and those are the moments when someone reads the binding documents.

A constitution records what the family has promised. The articles, the shareholders’ agreement and the will decide what actually happens.

One Position

A family constitution should be judged by the clauses built from it, not by the fact that it exists.

For any constitution, three questions make its core:

  1. Who may own shares?
  2. How are profits distributed?
  3. How does someone exit?

Then test each answer: in which binding document does it appear? An answer with a clause behind it has force. An answer without one is a promise still waiting for its clause.

This view would be wrong if families whose constitutions never reached a binding document came through a death, an exit or a dispute as well as families whose constitutions did. No study we have found has yet measured that.

Does your family have a constitution? If it does, which promises could a court enforce? If it doesn’t, which promises is everyone simply assuming?
