A share deal involving GmbH shares lives off the notarial deed. Unlike with a share purchase in a stock corporation, plain written form is not enough in Austria. Seller and buyer have to execute the assignment agreement before a notary in the form of a notarial deed. Without this form the assignment of the share is invalid and the economic handover stands on shaky ground.

This post explains the structure of an assignment agreement, the course of the notarial deed and the subsequent filing with the company register. The focus is on the mandatory minimum content, the interaction with the contract of obligation, the filing with the register of beneficial owners and typical pitfalls at the closing appointment.

From a lawyer perspective the clean sequence of steps decides whether the shares pass in a single sitting or whether rework is needed. How the share purchase is prepared overall is shown in the post on buying and selling GmbH shares.

01 Question 1

Is there already a draft share transfer agreement reviewed by the notary?

The notarial deed is the mandatory form for a transfer of GmbH shares. A draft pre-reviewed by the notary avoids content surprises and delays at the appointment.

All paths at a glance

Overview of all answers.

01

A private agreement is not enough. Only the notarial deed form makes the transfer effective.

The notarial deed is the mandatory form for the transfer of GmbH shares in Austria. A purely party-drafted contract is not sufficient. Send the draft to the appointed notary in good time for formal and substantive review, clarify the identity checks and align the necessary attachments.

Only with the deed executed by the notary does the transfer become effective. Whoever schedules the appointment without a pre-reviewed draft risks rework or an adjournment. A deeper look is provided by the post on buying and selling GmbH shares.

02

The formal sequence is well planned, the notarial deed can be scheduled.

If the contract draft is available in reviewed form and the company register and beneficial owner filings are prepared, the transfer can be completed in a single sitting at the notary. Keep the sequence: execution, payment of the purchase price, filing with the company register, update of the beneficial owner register.

For closing a detailed script is advisable. It sets out which documents are signed in which order and which confirmations have to be in place at the end. A first orientation is provided by the post on closing conditions.

03

The formal follow-up work is incomplete and delays completion.

Without prepared filings with the company register and the beneficial owner register the change of shareholders remains invisible to the outside. Above all the registration in the beneficial owner register has to be made within four weeks of reaching beneficial ownership. Whoever misses the deadline risks administrative fines.

Best to align the filings already on the day of execution. The notary and the tax adviser can take on the submission. A first assessment of your transaction is provided by our M&A transaction risk profile.

Structure of the share transfer agreement

A share transfer agreement typically consists of three layers. The first layer describes the transfer process itself: seller, buyer, the share with its capital portion and the description of the company with its register number. Without a precise description of the share the contract runs into a void. In particular with partial shares the split and the transfer have to correspond exactly.

The second layer governs the purchase price and its treatment. Here come the amount, due date and modality of payment. Common is a confirmation of payment directly in the deed or shortly afterwards. Where adjustment mechanisms such as working capital or net debt clauses are agreed, they are recorded in substance either in the notarial deed or in the underlying contract of obligation.

The third layer captures warranties, indemnities and ancillary obligations. Often the entire SPA warranty catalogue, or a reference to it, is already part of the notarial deed, supplemented by the operational handover. How the warranty catalogue is technically structured is shown by the post on the SPA warranty catalogue. The concept of share assignment is explained in the glossary.

The notarial deed in detail

The notarial deed is a special form that certain legal transactions in Austria require. For the transfer of GmbH shares it is mandatory. The notary checks the identity of the parties, explains the declarations, records them in a protocol and seals the original. An execution copy of the deed serves the parties as the document, the original remains with the notary.

At the appointment the contract is executed in the version drawn up by the notary. Last-minute change requests have to be incorporated without rush. Larger amendments call for a new draft. For that reason experienced parties send the final version at least a few days before the appointment and align the course of events including the required attachments.

Often further acts are recorded by the notary at the same time. These include the removal and reappointment of the managing directors, amendments to the articles of association or the admission of new shareholders by way of a capital increase. In this way the entire completion can be bundled in one appointment. The focus page on share purchase agreement shows how the deed and the contract interlock.

Company register, beneficial owners and follow-up obligations

After execution the managing directors file the new state of shareholders with the company register. The filing and the supporting documents are submitted electronically. It is common for the notary to handle the procedure. The entry has declaratory effect but creates the external visibility of the change that is decisive for banks, contractual partners and authorities.

Within four weeks of reaching beneficial ownership the update in the beneficial owner register has to be made. This obligation falls on the company but can be delegated to the notary, lawyer or tax adviser. Whoever misses the deadline risks administrative fines and the rejection of other filings.

Finally operational follow-up duties have to be discharged: notice to banks and contractual partners, update of the shareholders list, change at material contracts with a change-of-control clause and adjustment of internal powers of attorney. Deeper context on the conditions is provided by the post on closing conditions. The concept of the company register is explained in the glossary.

The stations of completion

How the share transfer runs formally

These stations lead from the signing-ready draft to the registered change of shareholders. Each one should be planned before the appointment.

Stations of the share transfer with actor, aim and typical pitfall
Station Actor and aim Typical pitfall
Draft agreement Parties and notary Notary-ready version with all attachments Late changes at the appointment
Notarial deed Notary and parties Execution with identity check Missing power of attorney or ID document
Purchase price payment Buyer to seller or trust Documented payment on completion day Delayed inflow of funds at the appointment
Company register Management or notary Registration of the new shareholder Incomplete attachments
Beneficial owner register Professional party representative Filing of new beneficial owners Four-week deadline overlooked

The listed stations are a typical course of events, not a rigid scheme. Order and responsibilities should be captured in a closing script before the appointment.

Caution with foreign involvement: Foreign notarial deeds are not readily recognised in Austria. The notarial execution of a transfer of an Austrian GmbH share abroad is possible only within narrow limits. Have the question of competent execution clarified before the contract runs through. Booking an initial consultation (72 euro) can quickly bring clarity.

Contract of obligation and completion in rem

Often the share purchase agreement, the SPA, is set up separately from the share transfer agreement. The SPA contains warranties, purchase price adjustments, closing conditions and all economic rules. The notarial deed then carries out the in-rem transfer. Both documents must be aligned in a contradiction-free way.

It is also possible to combine all content in a single notarial deed. This compact form saves a contract layer but makes the deed long and unwieldy. In larger transactions the two-tier structure with the SPA and a lean assignment agreement is more common because it facilitates negotiations.

In any event the notarial deed should clearly govern which document has priority in case of contradiction. The usual rule is that the later signed document or the more specific deed prevails. How warranties and closing conditions fit into the contract framework is shown in the post on the SPA warranty catalogue.

Frequent questions

Share transfer agreement, notarial deed and company register.

Why does the law require a notarial deed for GmbH shares? +

The notarial deed requirement is intended to create clarity and protection against haste. It forces the parties to have the contract explained by a notary and recorded in a form that is reliable as evidence. At the same time it facilitates the identity check and the link with the company register, which documents the essential ownership structure of a GmbH.

How long does the entry in the company register take after the notarial deed? +

The processing time depends on the competent court and on the completeness of the documents filed. Common is a few days to a few weeks. Whoever relies on a timely entry, for example because of a follow-on transaction, should submit the filing on the day of execution and instruct the notary with the transmission.

Who bears the notarial costs of the share transfer agreement? +

The notarial costs are allocated in the contract. Common are a split between seller and buyer or the sole assumption by the buyer. The notarial fee tariff is linked to the purchase price and the significance of the deed. A cost estimate obtained from the notary in advance protects against surprises.
