When day-to-day practice inside a group diverges from the written articles of association, you face a fork: formalise the practice, correct it back to the written text, or leave the mismatch for a later dispute. With a private equity sponsor on the cap table, that mismatch converts into warranty risk and exit risk, not internal housekeeping. This brief is for management and shareholders who have found the gap before the sponsor's counsel does.
What happens if you do nothing
Left alone, an informal practice does not correct itself. Each repetition makes it look more accepted, without turning it into a rule under Dutch law. Directors who act on the practice rather than on the articles carry a standing exposure to liability for decisions taken outside their proper authority.
If the mismatch compounds with financial distress, it can intersect with a debtor dissolved without liquidation, which changes who can still be held to account. At the next audit or the next reporting round to the sponsor's own investors, the gap surfaces as a finding, not a footnote.
The routes
This is squarely a question of corporate law and governance: three routes are open in the Netherlands, and each carries a different cost and a different signal to the sponsor.
| Route | What it takes | Time | Cost driver | What it gives you |
|---|---|---|---|---|
| Formalise: amend the statuten (articles of association) | A notarial deed, a general meeting resolution, and the sponsor's consent where the shareholders' agreement reserves it | Weeks, set by notary drafting and the statutory notice period for the meeting | Notarial and trade register fees, plus the time spent negotiating sponsor consent | A governance record that matches practice, ready for the next due diligence round |
| Correct: revert to the articles | A board resolution to stop the practice, and a decision on whether to ratify past acts taken under it | Immediate for the stop, ongoing for the compliance discipline | Internal legal review hours, no notarial step | Short-term compliance, with past decisions left exposed unless ratified |
| Escalate: request an inquiry from the Ondernemingskamer (Enterprise Chamber) | A shareholder with standing files a request, supported by evidence of the practice and its effect | Months, and contested once filed | Court fees and the cost of proceedings conducted with Dutch-qualified counsel of record | A court-ordered inquiry, public, with the possibility of interim measures |
What decides between them
Four questions do the sorting. Is the divergence a single lapse or a settled pattern across several decisions? Does the sponsor's shareholders' agreement give it a consent right over the fix itself, not only over the underlying decision?
Are past decisions taken under the informal practice voidable, or merely irregular? Is a sale or refinancing on the horizon, which turns a housekeeping question into a disclosure item before a Dutch court would ever see it.
Where the relationship with the PE sponsor is cooperative, formalising is usually cheaper than it looks. Where it is adversarial, correcting first and formalising later keeps the initiative with the board.
The deadline that runs
No single statutory date attaches to this fact pattern; the deadline that runs is practical, not filed with a court. Under the applicable Dutch rules, a limitation period for any liability claim starts once those with standing had actual knowledge of the decisions taken outside the articles, not once the practice began.
The nearer deadline is usually the sponsor's own reporting cycle: an audit, a quarterly report, or a refinancing covenant test will surface the gap whether or not you have addressed it first.
Evidence to secure now
Five items matter before either route is chosen. The current articles of association and any side letter or shareholders' agreement with the sponsor. Minutes of every meeting where the informal practice was used instead of the written procedure.
Dated board resolutions taken under that practice, with the authority relied on noted at the time or reconstructed now. Correspondence showing when the sponsor's representatives first had knowledge of the practice.
A related gap often travels with this one: annual accounts filed late under the same informal practice, so check the filing history while you gather evidence. A current extract from the trade register confirming who was authorised to act when each decision was taken closes the file.
Cost drivers
Three costs move the total. The notarial deed and trade register filing if you amend the articles, priced at the notary's standard tariff rather than at an hourly rate. The court fee for an inquiry request is published and updated periodically: check the current figure before you file.
The time spent on retroactive ratification of past decisions grows with the number of decisions taken under the informal practice, not with the size of any one of them.
What we would do in the first week
Pull the articles and the shareholders' agreement side by side and list every point where practice departs from text, not only the one that triggered this brief. Identify which past decisions were taken under the informal practice and whether each one is voidable or merely irregular.
Confirm whether the sponsor's consent rights reach the fix itself, not only the original decision. Then choose formalise or correct based on how often the divergence recurs, not on how large the last instance was.
What this does not cover
- The drafting of amended articles themselves, which is a separate engagement.
- A full liability analysis for each individual director exposed by the past decisions.
- The tax or accounting consequences of ratifying past decisions.
- Any jurisdiction other than the Netherlands, including where the sponsor's own fund documents sit under other law.
- The shareholders' agreement's dispute resolution clause, where that clause is not itself governed by Dutch law.
Questions
Does an informal practice ever override the written articles under Dutch law?
No. A practice that departs from the articles does not amend them; only a resolution to amend, taken and recorded as the articles themselves require, changes what the articles say. Consistent departure creates liability exposure for those who acted on it, not a new rule.
Can a private equity sponsor block the fix?
Only to the extent its consent rights say so. If the shareholders' agreement gives the sponsor a veto over amendments to the articles, or over specific categories of resolution, that veto reaches the formalise route directly and the correct route indirectly, through its effect on past decisions.
What happens to decisions already taken under the informal practice?
Each decision has to be checked separately. Some can be ratified by a properly convened resolution; others may remain voidable if a party with standing challenges them before a Dutch court within the period that runs from actual knowledge.

Where this leads
A note that maps the specific divergence against the articles and the shareholders' agreement is the fastest way to see which route costs less. Where the underlying structure itself needs mapping first, a structure report sets out the entities, the holdings and the decision rights before you choose. The formalise route sits inside our group reorganisation work, where articles and practice are brought back into line.
