Foreign NGO Branch in Bulgaria — Requirements, Documents and Apostille (2026)

Legal framework

The establishment and operation of a branch of a foreign non-profit legal entity in Bulgaria is governed by several core statutes, which together define both substantive conditions and the registration procedure:

• Non-Profit Legal Entities Act (NPLEA) — general rules applicable to NGOs and their branches;
• Commercial Register and Register of Non-Profit Legal Entities Act — procedure for entering the branch data;
• Hague Convention of 5 October 1961 abolishing the requirement of legalisation for foreign public documents — basis for the apostille;
• Code of Private International Law — applicable law to the foreign NPLE itself.

The combination means that the foreign NGO retains its personal law (the law of the state of incorporation), while the activity of the branch on Bulgarian territory is subject to mandatory Bulgarian rules, including public-order provisions.

Core principles

A foreign NGO may open a branch in Bulgaria only if its objectives and activities do not conflict with Bulgarian public order, good morals and mandatory statutory rules. The Registry Agency reviews compliance before entry.

Legal personality

The branch is not a separate legal entity — it is a dependent part of the foreign NGO. Obligations assumed by the branch are obligations of the parent organisation. Nevertheless, the branch receives its own UIC (Bulgarian unique identifier), can be a party to contracts, employ staff and open a Bulgarian bank account.

Public and private benefit

A significant advantage over a domestic NGO branch is that a foreign NGO branch may carry out activities either for public or for private benefit, depending on the objectives recorded in the foreign jurisdiction. A domestic NGO branch, by contrast, is locked into the status of its parent.

Dependence on the parent

If the foreign NGO is terminated or struck off in its home jurisdiction, the Bulgarian branch also ceases to exist. This is why the current standing certificate from the foreign registry is a central document for the Bulgarian file.

Foreign vs. domestic NGO branch — key differences

Although both types of branch are entered with the Registry Agency, the procedures and document sets differ substantially:

Branch name

The branch name on the Register is formed according to a strict pattern:

• the full name of the foreign NGO (as entered in the foreign registry);
• the word „branch“ (in Bulgarian: „клон“);
• the Bulgarian locality where the branch is seated.

Example: „Global Health Alliance — klon Sofia“. If the parent uses a Latin-script name, it is transliterated into Cyrillic, and both spellings are recorded in parallel.

Representation

The branch acts through a representative who performs legal acts in the name of the foreign NGO. The scope of the representative’s authority is defined by an express decision of the competent body of the parent — typically the General Assembly or the Management Board.

Form of empowerment

The empowerment of the representative must be in writing with a notarised signature. If the power of attorney is executed abroad, it is itself subject to apostille (or consular legalisation) and a certified Bulgarian translation.

Bulgarian contact

Good practice (and often an operational necessity) is for the representative to have either a permanent or at least a contact address in Bulgaria, so that communications from public authorities, banks and counterparties can be received. The branch may also sign a management or administrative services agreement with a local professional.

Required documents

Unlike a domestic NGO branch, where the file is limited to internal decisions, here most attachments originate abroad and are subject to apostille and translation:

1. Application A18 — on the template of the Registry Agency;
2. Notarised consent and signature specimen of the branch representative;
3. Founding act of the foreign NGO (statute or articles of association) — with apostille and certified translation; it is advisable to provide an anonymised copy with masked personal data for public display;
4. Certificate of current standing from the registry of the state of incorporation — with apostille and certified translation; no older than 3 months;
5. Protocol of the General Assembly or management body containing two separate resolutions: (a) to open a branch in Bulgaria and (b) to elect a representative; if executed abroad — with apostille and translation;
6. Notarised power of attorney for the branch representative defining the scope of authority;
7. Declaration of truthfulness of the declared circumstances on the statutory template;
8. Power of attorney if the file is submitted by a lawyer or a third person;
9. Proof of payment of the state fee.

When the file is submitted by a lawyer electronically using a qualified electronic signature, the state fee is reduced by 50 %, making electronic filing the universally preferred option.

Certified translation requirements

All documents drawn up in a foreign language must be accompanied by a Bulgarian translation meeting several requirements:

• carried out by a sworn translator registered on the list of the Bulgarian Ministry of Foreign Affairs (MFA);
• the translator’s signature certified by a notary or by the MFA depending on the specific regime;
• alternatively, the translation may be performed by a notary with certified language competence.

A translation made abroad by a local translator is, as a rule, not accepted for official entry into the Register. Even where a translation from the home jurisdiction exists, it typically has to be redone or re-certified in Bulgaria.

Apostille and legalisation

The certification regime for foreign public documents depends on whether the state of incorporation is a party to the 1961 Hague Convention.

Hague Convention states (EU and most jurisdictions)

An apostille is used — a single certification form which replaces the entire diplomatic and consular chain. The apostille is issued by the competent authority in the state of origin, most commonly the Ministry of Foreign Affairs or the Ministry of Justice. An apostilled document is accepted in Bulgaria without further authentication (apart from the translation).

Non-Hague states

Full consular legalisation applies in three steps:

1. notarisation of the document in the country of origin;
2. authentication by the Ministry of Foreign Affairs of that state;
3. legalisation by a Bulgarian diplomatic or consular mission (embassy or consulate).

In practice, consular legalisation takes significantly longer and often requires engaging a local agent in the state of incorporation.

State fees and timeline

The financial and time envelope of the procedure looks as follows:

Legal fees depend on complexity, the number of documents requiring legalisation and translation, and whether the organisation already has a ready founding act and board resolutions.

Ongoing obligations of the branch

Once entered in the Register, the branch assumes a series of recurring and operational obligations:

• Accounting for the activity in Bulgaria under the Accountancy Act;
• Tax registration with the National Revenue Agency (NRA), including VAT where taxable supplies are made or the turnover threshold is reached;
• Annual reporting to the Register of NPLEs — activity report and financial statements;
• AML compliance, where the activity falls within the Measures Against Money Laundering Act — e.g. foundations running grant programmes;
• Notification of any change in the parent organisation (seat, representatives, objectives, name) reflected on the branch file;
• FDI screening, where applicable, if the branch carries out activities caught by the Bulgarian foreign-investment screening regime.

Typical use cases

From our practice advising international clients, we observe several recurring categories of foreign NGOs opening branches in Bulgaria:

• International humanitarian organisations establishing an operational presence for coordinating activities in South-East Europe;
• Foreign foundations with grant programmes — frequently register a branch in order to disburse funds directly to Bulgarian beneficiaries;
• European research associations working with Bulgarian partner institutions — for instance within Horizon Europe projects;
• Religious and cultural organisations, where the scope of activity does not require incorporating a separate Bulgarian religious denomination;
• Development and technical cooperation entities — some agencies open a branch as a temporary platform before establishing an independent Bulgarian NPLE.
