How to Transfer or Buy Company Shares in Bulgaria (2026): Procedure, Documents & Registration

To transfer shares Bulgaria requires a defined legal sequence, a written transfer instrument, any corporate approvals mandated by the company’s articles, notarisation where the law or the constitution demands it, and registration with the Commercial Register maintained by the Registry Agency. From 1 January 2026 Bulgaria adopted the euro, which changes how share capital and consideration are expressed on filings and reshapes the fee schedules and conversion rules practitioners must apply. This guide sets out the full procedure for buyers and sellers of Bulgarian companies, limited liability companies (OOD/EOOD) and joint-stock companies (AD), with the exact documents, statutory timelines, costs, tax checkpoints and the 2026 conversion mechanics you need to close a transaction cleanly.

It is written for prospective buyers and sellers, in-house counsel, corporate advisers and foreign investors who need a procedural, decision-stage reference rather than a marketing overview.

Overview: what it means to transfer shares in Bulgaria

A share transfer moves ownership of a participation interest (in an OOD/EOOD) or shares (in an AD) from a current holder to a new one. The mechanics differ by company type, but every transfer ultimately depends on a valid transfer instrument, satisfaction of any internal approval requirements, and, for changes that affect the public register, an entry in the Commercial Register (Търговски регистър). The governing framework is the Commerce Act (Търговски закон), promulgated and amended through the State Gazette, together with the Commercial Register and Register of Non-Profit Legal Entities Act and the Registry Agency’s procedural rules on filings and forms.

Transfers arise in several contexts, each with its own formalities:

• Sale. The most common route, documented by a share purchase agreement (SPA) with price, payment terms and warranties.
• Gift. A gratuitous transfer, still requiring the correct instrument and, for an OOD, notarised signatures.
• Inheritance. Succession to a participation interest, which may trigger approval or buy-out mechanics under the articles.
• Merger or reorganisation. Shares change hands as part of a corporate restructuring under the reorganisation provisions of the Commerce Act.

Companies in scope include the OOD (multi-member limited liability company), the EOOD (single-member limited liability company), and the AD (joint-stock company). Foreign-owned entities and branches follow the same registry logic, with additional apostille, translation and AML documentation.

Eligibility: who can buy or receive shares

Both natural persons and legal entities, Bulgarian or foreign, may hold shares in a Bulgarian company. There is no general nationality restriction on ownership. However, certain regulated sectors (for example financial services, insurance and specific licensed activities) require sectoral consents or regulator notification before an acquisition of a qualifying holding can complete. Buyers should confirm at the outset whether the target operates in a licensed field, because a missed consent can void or delay the transfer.

Shareholder restrictions in the articles, approvals and pre-emption rights

The company’s articles of association routinely constrain transfers. In an OOD, the transfer of a participation interest to a third party (someone who is not already a member) generally requires a decision of the general meeting; transfers between existing members are usually freer. Many articles also grant existing members a right of first refusal (pre-emption right), meaning the seller must offer the interest to co-members before selling externally. Before you draft an SPA, obtain and read the current articles: failing to honour a pre-emption clause or approval requirement is a frequent cause of a refused registry filing. The pre-emption and approval regime derives from the Commerce Act and whatever the articles add on top of it.

Step-by-step share transfer procedure in Bulgaria

The following numbered procedure reflects a standard private transaction. Complexity, regulatory consents and cross-border elements will extend the timetable. The timeline table beneath the steps gives realistic durations for each stage.

1. Preliminary due diligence and SPA negotiation. Verify title, encumbrances, liabilities and corporate standing; negotiate price and terms.
2. Corporate approvals and pre-emption waivers. Obtain the general meeting or board decision and any first-refusal waivers required by the articles.
3. Execution. Sign the SPA and transfer instrument, notarise where required, and arrange payment (often via escrow).
4. Regulatory consents. Secure any sectoral approvals for licensed activities.
5. Registry filing. File the transfer with the Commercial Register.
6. Post-registration compliance. Update corporate books, bank mandates, tax and employment records.

Step 1, Preliminary due diligence and SPA negotiation

Before any money changes hands, the buyer should confirm the seller’s clean title to the shares, review the company’s obligations, litigation exposure, tax position, and material contracts, and obtain a fresh extract from the Commercial Register showing the current members or shareholders. Read the articles for transfer restrictions and pre-emption rights. Negotiation then produces the SPA, the core contract that fixes the purchase price, payment schedule, conditions precedent, representations and warranties, indemnities and completion mechanics. For a well-advised buyer, this is where risk is allocated; weak warranties discovered after closing are expensive to unwind.

Where you intend to transfer shares Bulgaria across borders, the diligence stage should also confirm the seller’s tax residency and any treaty position, because these determine withholding and reporting downstream.

Step 2, Board/shareholder approvals and pre-emption rights

Once terms are agreed, obtain the corporate consents the articles and the Commerce Act require. In an OOD, admitting a new third-party member typically needs a general meeting resolution; where pre-emption rights exist, the existing members must either waive them in writing or the seller must first offer the interest to them on the same terms. In an AD, transfers of registered shares may require updating of the shareholders’ book, and governance rules are generally stricter. Document every decision in properly minuted resolutions, the Registry Agency will expect to see them where a decision was legally necessary. Skipping this step is a classic reason a filing is rejected or later challenged.

Step 3, Execution: notarisation, signatures and payment mechanics

At execution the parties sign the SPA and the transfer instrument. For an OOD, the transfer of a participation interest requires the signatures of the transferor and transferee, and the content of the transfer agreement, to be notarially certified. For an AD, the requirement depends on the type of shares and what the articles specify. Payment is commonly handled through escrow or a conditional bank arrangement so that funds release against confirmed registration or against delivery of executed documents. Cross-border buyers should coordinate with their bank early, since KYC/AML checks and source-of-funds verification can delay large transfers. Since euro adoption on 1 January 2026, the consideration and any capital figures in the documents should be expressed in euro.

Step 4, Registry filing and forms

The transfer becomes effective as against third parties once entered in the Commercial Register. Filing is made to the Registry Agency using the prescribed application form for the relevant change, accompanied by the transfer instrument, corporate resolutions, the updated members’/shareholders’ record and supporting documents. Electronic filing through the Registry Agency’s portal is faster and attracts a lower fee than paper submission. Filings can be made by the company’s representative or by an authorised attorney. The registrar reviews the application and, if complete and compliant, enters the change; incomplete filings receive instructions to remedy defects within a set period.

Step 5, Post-registration compliance: corporate books, VAT and employment

Registration is not the end. Update the internal corporate books, issue or amend share records for an AD, and update the shareholders’/members’ ledger. Revise bank signatory mandates so the new ownership and management can operate accounts. Review whether the change affects the company’s VAT position or registrations, and confirm that any beneficial ownership entries are refreshed. Where the transaction changed management, notify employment and social security authorities as required. For post-transaction compliance obligations more broadly, see Company inspections in Bulgaria (post-transaction compliance).

Required documents for a share transfer in Bulgaria

Assembling a complete document bundle before filing is the fastest route to a clean registration. Missing a resolution, an apostille or a certified translation is a common cause of delay. The table below lists the standard documents; the exact set varies with company type and whether foreign parties are involved.

Notarisation, apostille and certified translations

For an OOD, notarial certification of the transferor’s and transferee’s signatures and of the content of the transfer instrument is required. Foreign public documents must generally be apostilled (for states party to the 1961 Hague Apostille Convention) or otherwise legalised, and any document not in Bulgarian must be accompanied by a certified Bulgarian translation. Rules on notarisation, powers of attorney and legalisation of foreign documents fall within the remit of the Ministry of Justice. Build translation and apostille lead time into your schedule, these steps regularly add days rather than hours.

Sample checklist for buyer and seller

• Seller. Clean title evidence, articles, resolutions/waivers, tax declarations, ID/company documents, notarised signatures.
• Buyer. Executed SPA, proof of payment/escrow confirmation, KYC/AML documents, power of attorney for the filing agent, apostilled and translated foreign documents.

Timeline and deadlines

A straightforward private transfer with no regulatory consents commonly completes within one to two weeks once documents are ready. A more complex transaction, with detailed due diligence, corporate approvals, notarisation and sectoral consents, typically runs one to six weeks, and licensed-sector consents can extend the timetable well beyond that. Electronic filings are processed faster than paper submissions. The Step/Who/Duration table above gives stage-level durations; use it to build a realistic critical path rather than relying on the fastest theoretical case.

Statutory filing deadlines and administrative windows

Certain corporate changes must be filed with the Commercial Register within the statutory window after the event giving rise to them, and tax reporting obligations attach separate deadlines, capital gains reporting for the seller falls due within the periods set under the applicable tax legislation administered by the National Revenue Agency. Confirm the current filing window and the applicable registry processing standard on the Registry Agency portal before you commit to a completion date, and diarise the seller’s tax filing deadline at signing so it is not missed after the parties disperse.

Costs, taxes and fees

Budgeting should account for registry fees, notary charges, legal fees, translation and apostille costs, escrow and bank charges, and the seller’s tax exposure. The ranges below are indicative only; always confirm current registry and notary tariffs, which are set officially and periodically revised.

On tax, gains realised by the seller on the disposal of shares are generally subject to Bulgarian income tax under the applicable regime, while the sale of shares itself is generally outside the scope of VAT. Buyers and sellers should nevertheless verify the current VAT treatment and the applicable capital gains regime and rate with the National Revenue Agency for the specific facts of their transaction, noting that certain disposals of shares admitted to trading on a regulated market may benefit from an exemption.

Tax treatment for non-resident sellers and cross-border payments

Where the seller is a non-resident, the transaction may engage Bulgarian withholding and reporting obligations, and relief may be available under an applicable double tax treaty. Treaty relief is not automatic, it usually depends on documentation and, in some cases, a prior procedure with the tax authority. Cross-border consideration must clear KYC/AML checks at the receiving bank, and source-of-funds evidence should be prepared in advance. Confirm the withholding position and any treaty relief mechanics with the National Revenue Agency before completion so the net proceeds to the seller are known with certainty.

What changed in 2026: euro adoption and converting share capital to euro

Bulgaria adopted the euro on 1 January 2026. The practical consequence for anyone who wants to transfer shares Bulgaria is that monetary figures, share capital, the nominal value of participations or shares, and the consideration on filings, are now expressed in euro. Share capital previously stated in Bulgarian lev (BGN) must be converted and stated in euro according to the official conversion and rounding rules, and registry forms that require a monetary amount expect euro figures. Where a filing references legacy BGN amounts for historical continuity, follow the official guidance on how the conversion is applied and, where required, how the legacy amount is shown.

The fixed conversion rate and the mechanics of currency conversion are set out in the euro-adoption legislation and applied under the auspices of the Bulgarian National Bank, with supporting tax and changeover guidance from the Ministry of Finance and the Council of Ministers. As a worked illustration of how a conversion affects a filing, take a historical share capital figure in BGN and apply the official fixed conversion rate to arrive at the euro amount that now appears on the register; the same logic applies to the nominal value of each participation and to a share price stated in an SPA.

Because rounding and the treatment of nominal values can affect whether capital totals still reconcile after conversion, confirm the exact methodology in the official guidance before filing, and expect that some companies will need a formal capital amendment to align nominal values cleanly in euro. Registry practice on conversion-related entries is expected to continue settling during 2026, so verifying the current form requirements immediately before filing is prudent.

Special situations and cross-border issues

Not every transfer is a simple domestic sale of a private OOD. The mechanics diverge meaningfully between company types and become more involved where foreign parties are involved.

Non-resident sellers and buyers

Cross-border transactions add layers: withholding and tax registration considerations for the seller, treaty-relief documentation, banking KYC/AML and source-of-funds checks for the buyer, and apostille plus certified translation for every foreign document in the filing bundle. Confirm the seller’s tax residency and any treaty position during diligence, and align the payment route with the receiving bank’s compliance requirements well before completion. Where a foreign representative signs or files, ensure the power of attorney is notarised and apostilled so it is accepted by the Registry Agency.

Common pitfalls and how to avoid them

• Ignoring pre-emption rights. Offer the interest to existing members first or obtain written waivers before signing with a third party.
• Missing corporate approvals. Confirm and minute every resolution the articles or the Commerce Act require before filing.
• Incorrect euro conversion. Apply the official fixed conversion rate and methodology to capital and price figures; reconcile nominal values after conversion.
• Incomplete documentation. Use the required-documents checklist and assemble the full bundle before submitting to avoid remedy notices.
• Defective notarisation. Ensure signatures and content are notarially certified where required for an OOD transfer.
• Missing apostille or translation. Apostille and certify-translate all foreign documents in advance.
• Tax non-compliance. Diarise the seller’s capital gains reporting deadline and confirm any non-resident withholding with the NRA.
• Bank payment delays. Start KYC/AML and source-of-funds preparation early for cross-border consideration.
• Stale register extract. Obtain a fresh Commercial Register extract close to filing so ownership data is current.
• Overlooking sectoral consents. Check whether the target is regulated and secure consents before completion.
• Weak SPA warranties. Allocate risk properly in the SPA rather than relying on post-closing remedies.

Templates and next steps

Indicative SPA clauses, a title-and-encumbrance warranty, a conditions-precedent clause tying completion to registry filing, and an escrow-release mechanism, help structure a robust contract, but they are illustrative only and not a substitute for tailored legal advice.

Conclusion

To transfer shares Bulgaria successfully in 2026, follow the sequence carefully: diligence, corporate approvals and pre-emption waivers, correctly notarised execution, euro-denominated documentation, clean registry filing and disciplined post-registration compliance. The euro changeover and evolving registry practice make it more important than ever to verify current forms, fees and conversion rules before completion, and to confirm the seller’s tax position, including any non-resident withholding, with the authorities. Handled methodically, a share transfer in Bulgaria is a predictable process; handled loosely, it stalls at the register.
