Selling shares in an Estonian OÜ is a well-defined legal process, but it is not a process you can navigate informally. A notary is involved in almost every case, specific documents must be prepared in advance, and the Business Register must be updated after the transaction completes. Getting any step wrong delays the transfer and creates compliance exposure for both the seller and the buyer. This guide covers what is actually required, where the notarised form exception applies, and what happens after the sale agreement is signed.
The role of a notary in Estonian share sales
A notary plays a central role in share transfers in Estonia. As a general rule, share transfers must be executed in notarised form: the sale agreement is signed in front of, or authenticated by, a notary. The notary verifies the identity of the parties, confirms the transaction meets legal requirements, and authenticates the document so it has legal standing for registration.
For companies where the share capital is fully paid and registered at a minimum of €10,000, shares can be transferred without a notarised form. This exception makes the process faster and significantly more convenient: the parties can complete the transfer agreement in writing without involving a notary for the signing itself.
The threshold is specific: the share capital must be both paid and registered at €10,000 or more. A company that has a share capital of €10,000 stated in its articles of association but has not fully paid and registered that capital does not qualify. Before proceeding without notarisation, verify the company's registered and paid-up share capital against the Business Register entry.
Companies with fully paid and registered share capital of at least this amount can complete share transfers without a notarised form, making the transaction faster and less costly. For all other companies, a notarised form is required.
How the transaction can be completed: e-Notary, in person, or by power of attorney
Estonian share sales accommodate parties located anywhere in the world, through three distinct routes depending on the seller's situation.
-
1
e-Notary for e-residents
E-residents can sign share transfers remotely through Estonia's e-Notary system using their e-Residency digital identity. This is the most efficient route for e-resident sellers and buyers: no travel required, fully authenticated, legally equivalent to an in-person notarial transaction.
-
2
In person at an Estonian notary's office
Non-residents and legal entities can attend an Estonian notary's office in person to complete the transfer. This is required when the e-Notary route is unavailable and no power of attorney has been issued. The notary verifies identity, authenticates the agreement, and ensures the transaction is correctly documented.
-
3
Notarised power of attorney to a local representative
Non-residents who cannot travel to Estonia and are not e-residents can issue a notarised power of attorney to a local lawyer or representative in Estonia. That representative then completes the share transfer on the seller's or buyer's behalf. If issued outside Estonia, the power of attorney typically requires an Apostille.
What must be prepared before the share sale can proceed
Several documents must be in place before the transfer agreement can be executed. The specific requirements depend on the seller's personal circumstances and on whether any parties to the transaction are legal entities rather than natural persons.
-
Spouse consent or documentation (if the seller is married without a prenuptial agreement)
If the seller is married and has no prenuptial agreement separating the shares as personal property, a notarised power of attorney signed by the seller's spouse is required. If the parties are outside Estonia, an Apostille on the spouse's signature may be needed. A certified copy of the marriage certificate, divorce certificate, or prenuptial agreement must also be provided depending on the seller's situation. -
Certified Commercial Register extract (for foreign legal entity parties)
If any party to the share sale is a foreign legal entity, a certified extract from its home country's Commercial Register must be provided, with Apostille where applicable. This confirms the entity's legal existence, registered address, and authorised signatories. -
Certified Estonian translation of all foreign documents
The Estonian Commercial Register requires all submitted documents to be fully translated into Estonian by a sworn translator. Foreign-language documents, including register extracts, marriage certificates, and powers of attorney issued abroad, must be accompanied by their certified Estonian translations before the Business Register will process any post-sale update. -
Apostille on foreign public documents where required
Documents issued by public authorities in countries that are parties to the Hague Apostille Convention must carry an Apostille to be recognised in Estonia. This applies to powers of attorney, register extracts, and certificates issued outside Estonia.

Updating the Business Register after a share sale
Once the share sale agreement is executed and the transfer is complete, the management board of the company must update the shareholder information and beneficial owner data in the Estonian Business Register. This is a legal obligation, not an optional administrative step. An unregistered shareholder change creates a discrepancy between the company's actual ownership and its public record, which can affect subsequent company decisions, banking relationships, and compliance assessments.
The Business Register update is also the natural moment to review whether any other changes are needed. If the incoming shareholder is joining the management board, the board composition must be updated at the same time. If the share sale changes the beneficial ownership structure of the company, the beneficial owner register must be updated to reflect the new position. If the articles of association reference the previous ownership structure in any way, this is the point at which to review and amend them.
Board of directors: Does the incoming shareholder join the board? If so, the board change must be registered at the same time as the share transfer.
Beneficial owner register: Estonian law requires companies to maintain accurate beneficial owner records. A share sale that changes who ultimately controls the company requires an immediate update to the beneficial owner information held at the Business Register.
Articles of association: If the articles specify shareholder names, share structures, or pre-emption rights that have been affected by the sale, this is the moment to update them. Amending the articles requires a notarised shareholder resolution.
Signatory authority: If the share sale results in a change of the person authorised to sign on behalf of the company, bank mandates, service agreements, and procurement relationships should be updated accordingly.
The share sale process at a glance
-
Check the notarisation requirement. If the company's paid and registered share capital is at least €10,000, the notarised form is not required. In all other cases, a notary must authenticate the transfer.
-
Prepare all required documents in advance. Spouse consent, certified register extracts for legal entity parties, Estonian translations, and Apostilles where required. Missing documents at the signing stage delay the entire process.
-
Choose the transaction route. E-Notary for e-residents, in person at an Estonian notary for non-residents, or by power of attorney issued to a local representative.
-
Update the Business Register after signing. The management board must update shareholder and beneficial owner information. Review simultaneously whether the board composition, articles of association, or signatory mandates need to change.
