Croatian citizenship through a great-grandparent
This path is for you if
- One of your great-grandparents was born in what is now Croatia.
- They emigrated to settle abroad, which for this generation almost always means long before 8 October 1991.
- You can trace a direct line of birth certificates from them, through your grandparent and parent, to you.
- You are prepared for record-hunting in two countries.
What the law says
Your legal basis is the same Article 11 that covers grandchildren: an emigrant and their descendants may naturalise without giving up their citizenship, without living in Croatia and without the language and culture test that other foreigners take.
The Act does not name a number of generations; it says “descendants”. In practice each extra generation adds certificates, and the Ministry of the Interior decides each case on the evidence in the file. If a link is missing, the application can fail, however Croatian the family story.
As on every Article 11 path, you must be an adult and have no security or legal-order obstacles, which your police check shows.
Documents for this path
Four generations, four birth certificates, and every marriage where a surname changed. Australian and New Zealand certificates need an apostille and a certified Croatian translation; the consulate wants originals no older than six months.

How this differs from the other paths
The grandparent path links three people; this one links four, and the oldest records are usually the hardest to find. Your great-grandparent may have been born when Croatia belonged to another state, so place names and the language of the records can differ from what the family remembers.
Emigration is usually easier to establish than on the grandparent path, because a great-grandparent who settled here typically did so generations before 1991. The challenge is the paper trail, not the date.
Where to start looking
Start with what the family already holds: old passports, naturalisation papers, letters with Croatian place names, funeral cards. A village name is the key that unlocks the Croatian records.
Then work forwards from your great-grandparent to you, ordering certificates generation by generation, so each one names the person in the next. Retrieving records from Croatian archives is part of our Premium service if you would rather not do it yourself.
How long it takes
Allow more time for research than on any other path: locating a great-grandparent’s birth record can take months before you order a single apostille.
After lodging, the ministry’s estimate for Australia is the same as for other applicants, 12 to 24 months for a complete application.
Frequently asked questions
How many generations back can I go?
The Act says “an emigrant and their descendants” without naming a number of generations. Every generation must be documented with birth certificates that name the next, and the Ministry of the Interior decides each case on its evidence.
What if I cannot find my great-grandparent’s birth record?
Without it the line has a gap. Start with a place of birth from family papers; finding records in Croatian registers and archives is part of our Premium service.
About our Premium serviceThe name is spelt differently on every record. What now?
The consulate requires names, surnames and birth details to match across documents. Each difference needs a document that explains it, such as a marriage certificate or a change-of-name record.
Does a great-grandparent claim take longer?
The document stage usually does. Once a complete application is lodged in Australia, the Croatian foreign ministry’s estimate is the same as for anyone else: 12 to 24 months.
