If you are planning to apply for Croatian citizenship by descent, one of the most important steps is preparing the correct documentation.
Incomplete or incorrect documents are one of the most common reasons for delays or rejection. This checklist will help you understand exactly what you need.
Core Documents for Croatian Citizenship by Descent
Most applicants will need the following core documents:
- valid passport
- birth certificate of the applicant
- birth certificate of the Croatian ancestor
- birth certificates for each generation in between
- marriage certificates (if applicable)
These documents are used to establish your identity and family lineage.
Proof of Croatian Ancestry
To qualify, you must prove that your ancestor was Croatian.
This is typically done through:
- birth certificate from Croatia
- domovnica (proof of Croatian citizenship)
- historical records from Croatia
The ancestor must have emigrated before 8 October 1991.
Documents Linking the Family Line
You must provide documents connecting each generation from the ancestor to you.
This includes:
- parent’s birth certificate
- grandparent’s birth certificate
- marriage certificates linking family members
All documents must clearly show the relationship between generations.
Additional Supporting Documents
In some cases, additional documents may be required:
- emigration records
- naturalization certificates

- church baptism records
These documents help support your application if primary records are missing.
Translation and Certification Requirements
