If you run an Estonian company from abroad, there is a good chance that at some point your company's structure will need to change. A co-founder leaves. A new investor joins. Your original Articles of Association no longer reflect how the company actually operates. These are routine situations, but the legal process behind them is not always obvious, especially for founders who are not based in Estonia and are not familiar with the Estonian Business Register (Äriregister).
This guide covers the two changes we handle most often for foreign founders: board member updates and Articles of Association amendments. We will explain what each involves, when you need to do it, and what tends to go wrong.
Part 1: Board member changes
The board of an Estonian OÜ (private limited company) or AS (public limited company) is the company's legal management body. Board members are listed in the Business Register and have the authority to represent and sign on behalf of the company. This makes keeping the register up to date not just a formality, it is a legal requirement.
When does a board member change need to be registered?
Any time a board member is added, removed, or replaced, the change must be filed with the Business Register. This includes situations where a co-founder steps back from an active role but remains a shareholder, if they are no longer on the board, that must be reflected in the register.
⚠ Common mistake: Agreeing internally that someone has left the board but never filing the change. Until the update is submitted to and accepted by the Business Register, the departing person remains a legal representative of your company. They can still sign contracts and bind the company. This is a liability risk for both parties.
What the process looks like
- 1Board decision or shareholder resolution. Depending on your Articles of Association, removing or appointing a board member requires either a board resolution or a shareholders' meeting decision. The correct document must be prepared and signed.
- 2Submission to the Business Register. The change is submitted electronically via the e-Business Register portal. In most cases this requires digital signatures, either an Estonian ID-card, Mobile-ID, or a notarised power of attorney, if the signatory does not have Estonian digital signing capability.
- 3Confirmation and updated extract. Once processed, typically within a few business days, the register is updated. You should obtain a fresh extract confirming the new board composition.
No Estonian digital ID? If you or the outgoing/incoming board member cannot sign digitally with an Estonian ID-card or Mobile-ID, the process requires a notarised and apostilled power of attorney. This is something 1Office can prepare and guide you through — it adds time, so plan ahead rather than doing this under pressure.
One more thing: notify your bank
After any board member change, notify your company's bank and update your authorised signatories. Banks do not automatically receive Business Register updates. If an outgoing board member still has signing authority on the account, that needs to be corrected separately.
Part 2: Articles of Association updates
The Articles of Association (põhikiri) is your company's foundational legal document. It sets out how the company is governed: how decisions are made, what the board can and cannot do independently, how shares are structured and transferred, and what happens when shareholders disagree.
Many founders set up their Estonian company using a standard template and never revisit the Articles again. That is fine when the company is simple and nothing has changed. But the moment your structure evolves, those boilerplate Articles can start creating real problems.
Signs your Articles of Association need updating
| Situation | Why the Articles may need to change |
|---|---|
| You are bringing in an investor | Share classes, voting rights, or transfer restrictions may need to be added or adjusted to reflect the investment terms. |
| A shareholder is leaving | Pre-emption rights and share transfer rules in the Articles govern how this works. If the Articles are vague or silent, disputes become harder to resolve. |
| Your board structure is changing | If you are adding a supervisory board or changing how many board members are required, this must be reflected in the Articles. |
| Decision-making thresholds need adjusting | Standard Articles often require unanimous shareholder approval for many decisions. Growing companies often need to lower these thresholds to function efficiently. |
| The company name is changing | A name change always requires an Articles amendment, since the company name is defined there. |
What the amendment process involves
- 1Draft the amended Articles. The new version must comply with the Estonian Commercial Code and clearly reflect the changes being made. This is where legal expertise matters — a poorly drafted clause can cause more problems than it solves.
- 2Shareholder approval. Amendments to the Articles of Association require a shareholders' meeting resolution. The required majority depends on what your current Articles say — typically at least two-thirds of votes represented at the meeting.
- 3Notarisation (if required). Certain changes — including share capital alterations — require notarisation. A standard Articles amendment for an OÜ can usually be filed without a notary if done through the e-Business Register with digital signatures.
- 4Filing with the Business Register. The updated Articles and the shareholder resolution are submitted together. Once accepted, the new Articles are publicly visible in the register.
Good to know: The Business Register makes your Articles of Association publicly available. Anyone — a bank, a potential partner, a client — can download them. Outdated or template Articles that no longer reflect your actual structure can raise questions you do not want to answer.
Board changes and Articles updates often go together
In practice, these two processes frequently happen at the same time. A co-founder leaves — so you need to remove them from the board and update the Articles to reflect the new shareholding structure and decision-making rules. An investor joins — new board member, new share class, amended Articles.
Handling both in a single coordinated process is more efficient and avoids the situation where the register reflects one state of the company while the internal documents reflect another. Our legal team at 1Office Estonia handles both in parallel, working alongside our accountants where share capital or ownership changes also have accounting implications.
If you are unsure whether your Articles need updating, or if a board change is overdue, the starting point is usually a short review of your current documents. We can tell you quickly what needs to change and what does not.
