Proving Bulgarian origin: the records that support Bulgarian citizenship by descent

Bulgarian citizenship by descent rests on two facts shown on paper: that an ancestor, no further back than a great-grandparent, was of Bulgarian origin, and that this person is your ancestor. The law relies on official records for both, so family recollections, a surname or a DNA test cannot take their place. This guide explains which records serve the purpose, where they are kept, and what can be done when the word “Bulgarian” is missing from the document you expected.

What the law asks for

Article 15(2) of the Bulgarian Citizenship Act, the law that governs Bulgarian citizenship, requires official documents issued by Bulgarian or foreign authorities that prove kinship with at least one ancestor of Bulgarian origin up to the third degree. In practice, “third degree” means a parent, a grandparent or a great-grandparent. The documents must give the ancestor’s names and show how he or she is related to you.

A complete file therefore answers two questions:

1. Was the ancestor Bulgarian? At least one record describes him or her as Bulgarian.
2. Is the ancestor yours? An unbroken chain of birth and marriage records connects each generation to the next, down to you.

The two questions are often answered by different documents. The general rules of the application are explained in our guide to Bulgarian citizenship by descent.

Imagine Anna, who lives in Toronto. Her great-grandfather was born in a Bulgarian village in what is today the Odesa region of Ukraine. She needs one record that calls him Bulgarian and a chain of certificates leading from him to her.

Records that name the ancestor as Bulgarian

• Birth, marriage and death records from Bulgaria or any other country that describe the ancestor as Bulgarian. In records from Ukraine or Moldova this is usually the “nationality” field of a Soviet-era certificate, where the entry reads болгарин (Bulgarian man) or болгарка (Bulgarian woman).
• Passports, military papers, and school or university diplomas that state nationality.
• Parish registers, the books in which Orthodox, Catholic and Protestant parishes recorded baptisms, marriages and burials. Entries from the 19th and the first half of the 20th century carry particular weight because they were made at the time of the event itself.
• Records of the Bulgarian Orthodox Church of baptism, marriage and burial. Bulgarian law accepts church documents as proof of origin.
• A court decision establishing Bulgarian origin, issued by a Bulgarian or a foreign court.
• Emigration lists and census records.

Documents issued by Bulgarian community associations abroad are not primary proof. The provision that allowed them was repealed in 2021, but they can still support the file before the Advisory Council described below.

Records that link the generations

The second question is answered by civil records for each generation:

Generation	What you need
Great-grandparent (3rd degree)	birth record naming him or her as Bulgarian, or another record that does; death record if available
Grandparent	birth record and marriage record
Parent	birth record and marriage record
You	birth record; marriage record and name-change documents if your name changed

Marriage records matter because they explain changes of surname. The records you file should be originals or duplicates issued by the competent authority, meaning a new official copy produced by the office that holds the register. Plain photocopies are not accepted, and notarised copies are accepted only when the original has been lost and cannot be reissued.

Where Bulgarian birth records and other proof are kept

Record	Where to look
Soviet-era birth certificates from Ukraine or Moldova with “Bulgarian”	civil registry office, its archive, regional state archive
Old passports and military papers	family papers; in Ukraine and Moldova also the military registration office
Parish registers of Bulgarian Orthodox parishes	regional state archives of Odesa, Zaporizhzhia and Mykolaiv oblasts (Ukraine); state archives of Moldova; archives of Bessarabia and the Budjak
Bulgarian school certificates and diplomas	regional archives in Bulgaria
Employment books, personnel files, questionnaires	the employer or its successor archive

It is worth looking beyond the birth certificate. Nationality was often recorded in documents families think of last, such as a military booklet, a workplace personnel file, a school certificate or a parish entry, and one such record can answer the first question. In Anna’s case, the family’s birth certificate does not mention nationality, but her great-grandfather’s military booklet describes him as Bulgarian, so the booklet becomes the central document of her file.

Original or re-issued?

Both old-form and new-form documents are accepted. Even so, an original record made at the time of the event is the strongest evidence, because it shows what was written down then. A certificate re-issued decades later from the same register is also accepted, but it may need further records to support it. For that reason it is best to file the original whenever the family still has it.

One more situation is worth checking. If one of your parents was a Bulgarian citizen when you were born, for example a parent born in Bulgaria who later emigrated, you may already be Bulgarian by birth rather than needing to apply. Bulgarian nationality law explained describes when this applies.

If no record says “Bulgarian”

This is common, and the procedure offers several ways forward:

1. Search more widely. Military papers, workplace files, school records and parish registers often state nationality when the birth certificate does not.
2. Be ready for a request. The Minister of Justice may ask for additional documents, and they have to be provided within 14 days of notification.
3. The Advisory Council. The ministry may refer the file to the Advisory Council at the State Agency for Bulgarians Abroad, a body that gives its opinion on questions of Bulgarian origin. The council does so within two months. It considers whether you speak Bulgarian, whether you identify as Bulgarian, and whether you belong to a Bulgarian community abroad, come from a place that was once part of the Bulgarian state or of the Bulgarian Exarchate (the Bulgarian Orthodox Church organisation of the Ottoman period), or have ancestors with traditional Bulgarian names.
4. A court. In disputed cases, Bulgarian origin can be established by a court.

An application cannot continue, however, if the file contains no documents of kinship with an ancestor of Bulgarian origin at all. In that case the proceedings are terminated, which means the application is closed without a decision on the merits.

Translation and apostille

Every document that is not in Bulgarian has to be translated by a licensed translator, and the translator’s signature is notarised. If you apply through a Bulgarian consulate, the consular service certifies the signature instead. The translation is filed together with the original or the duplicate.

Some documents also need an apostille, a standard certificate confirming that a public document is genuine so it can be used in another country. Whether one is needed depends on the issuing country:

Country that issued the document	Apostille
Moldova, Kazakhstan	required
Ukraine	not required, under the bilateral treaty with Bulgaria
Russia, Belarus	formally not required; recommended in practice
Armenia, Georgia, Uzbekistan, Azerbaijan	treaties exist; acceptance without apostille in citizenship cases is not confirmed, so apostilling is safer
EU countries, such as Romania	not required for public documents under EU Regulation 2016/1191
Bulgaria	not required

No certificate of Bulgarian origin

Until 15 March 2021, applicants first had to obtain a certificate of Bulgarian origin from the State Agency for Bulgarians Abroad before they could apply. That step was abolished, so a description of the process that begins with this certificate reflects the earlier procedure. Today the records go directly to the Ministry of Justice together with the application. The full rules of the Act are explained in Bulgarian nationality law explained.
