Issuing Body: Guozun Cathay Associates, Croatia Office
Date of Conclusion: 7 January 2026
Core Achievements: Full completion of cross-border marriage registration, family reunion residence permit and public school enrollment procedures for minor children, with zero rejections throughout the entire process
This case was jointly handled by the Croatia Office of Guozun Cathay Associates and the Cross-Border Family Law Team of the Beijing Headquarters. Strictly abiding by the relevant laws and regulations on marriage registration, alien residence and basic education in China and Croatia, and relying on Guozun’s dual-jurisdiction practice qualifications and cross-border legal service experience, the firm provided Chinese citizens with full-chain, one-stop legal services covering from marriage registration to settlement and school enrollment.
This case has been included in Guozun Cathay Associates’ 2026 Typical Case Library for Cross-Border Marriage and Family Law. Its case-handling model of “dual-jurisdiction document compliance + local procedure implementation + multi-node coordinated advancement” has been widely applied to the handling of cross-border marriage and settlement cases in Central and Eastern Europe.
I. Case Background and Entrustment Process
Ms. Li, a Chinese citizen who is remarried, met and fell in love with a Croatian national during her trip to Croatia. The two parties planned to complete marriage registration in Croatia and settle there long-term, and to bring Ms. Li’s 14-year-old minor child to the local area for basic education. Being unfamiliar with the local policies and procedures of marriage registration, alien residence permit and children’s school enrollment in Croatia, and faced with complex links such as cross-border document notarization and authentication, and custody determination, Ms. Li decided to entrust a professional institution to provide full-process legal services.
On 18 June 2025, Ms. Li was connected to the Croatia Office through the Beijing Headquarters of Guozun Cathay Associates. Given that the case involved three core difficulties — recognition of document validity under both Chinese and Croatian jurisdictions, residence qualification for minor children accompanying the applicant, and procedure connection of multiple administrative links — the Croatia Office activated the “Sino-Croatian Collaborative Case Handling Mechanism” on the same day, and set up a special case handling team together with the Beijing Headquarters. The team was jointly undertaken by local family law practitioners in Croatia and foreign-related family law lawyers from the Beijing Lawyers Association, who were fully authorised to handle all procedures for the principal from marriage registration to settlement and school enrollment.
II. Full Procedure of Sino-Croatian Joint Case Handling
This case adopted a standardised collaborative model where “the Beijing Headquarters is responsible for document compliance under Chinese jurisdiction and overall scheme coordination, while the Croatia Office is responsible for local administrative liaison and procedure implementation”. Written outcomes and verifiable nodes were formed in all links, ensuring the entire process is traceable and controllable:

III. Core Case Handling Difficulties and Authoritative Solutions
The difficulties in handling this case are common issues for Chinese citizens going to Croatia for marriage and settlement. Relying on dual-jurisdiction professional capabilities and local practical experience, the Sino-Croatian joint team of Guozun has formed a replicable standardised solution:
1.Compliance Recognition of Cross-Border Marriage Registration Documents for Remarried Persons
(a)Professional Basis: Articles 21 and 22 of China’s Law on the Application of Laws in Foreign-Related Civil Relations, Article 47 of the Notarization Procedure Rules; and the specifications for foreign-related marriage registration documents under Croatia’s Family Law.
(b)Solution: Established a three-level document compliance system of “domestic notarization + consular authentication + local verification”. For remarriage situations, focus was placed on supplementing the certificate of entry into force of divorce judgment and the declaration of no spouse, strictly matching the requirements of Croatian registration authorities on translation qualifications, document formats and authentication levels. Through the pre-review mechanism, the material defect rate was reduced to zero, achieving one-time approval of registration applications.
2.Qualification Connection and Simultaneous Approval of Residence for Minor Children Accompanying Migrants
(a)Professional Basis: Relevant provisions on family reunion residence under Croatia’s Aliens Act, and Chinese rules on cross-border guardianship and kinship recognition for minors.
(b)Solution: The minor child was taken as a dependent applicant for the residence permit and submitted the application bound with the main applicant. The full set of dual-authentication documents of birth certificate, custody ownership and kinship relationship were perfected in advance, forming an evidence chain where materials under both Chinese and Croatian jurisdictions confirm each other. This ensured that the residence applications of the main applicant and the child were accepted, reviewed and approved simultaneously, avoiding delays to the child’s school enrollment plan due to procedural gaps.
3.Time Coordination and Node Control of Multi-Link Procedures
(a)Professional Basis: Statutory processing cycles and declaration time limits for marriage registration, residence approval and compulsory education enrollment in Croatia.
(b)Solution: Formulated a full-process node control schedule, clarified the sequential dependency relationship and latest submission deadline of each link, and adopted a parallel advancement model of “pre-launching the next link upon completion of the previous one” — residence material preparation was launched on the day of marriage registration completion, and school pre-review of enrollment materials was conducted in advance at the late stage of residence approval. The overall processing cycle was shortened by 22% compared with the conventional self-handling path.
4.Optimisation of Handling Pathways Under Sino-Croatian Institutional Differences
(a)Professional Basis: Differences in rules between China and Croatia in terms of marriage registration systems, alien residence management and compulsory education systems.
(b)Solution: Relying on the professional judgment of the dual-jurisdiction lawyer team, on the premise of strictly abiding by local laws and regulations in Croatia, and combined with the actual situation of the principal’s remarriage and child accompanying migration, the registration jurisdiction and residence application channel with smoother policy implementation were selected. Policy ambiguous zones and implicit review standards were avoided in advance, ensuring the entire process is legal and compliant without policy risks.
IV. Applicable Legal Authorities for This Case
1. Chinese Laws
(a) Article 21 of the Law of the People's Republic of China on the Application of Laws in Foreign-Related Civil Relations: The law of the parties’ common habitual residence shall apply to the conditions for marriage; if there is no common habitual residence, the law of the common state of nationality shall apply; if there is no common nationality and the marriage is contracted at the habitual residence or the state of nationality of one party, the law of the place where the marriage is contracted shall apply.
(b) Article 22 of the Law of the People's Republic of China on the Application of Laws in Foreign-Related Civil Relations: A marriage shall be valid if its formalities conform to the law of the place where the marriage is contracted, the law of the habitual residence of either party, or the law of the state of nationality of either party.
(c) Article 47 of the Notarization Procedure Rules: Where a notarial certificate needs to be used abroad and the country of use requires authentication first, it shall be authenticated by the Ministry of Foreign Affairs of the People’s Republic of China or an institution authorised by it, and by the embassy (consulate) of the relevant country in the People’s Republic of China.
(d) Relevant provisions of the Measures for the Administration of Primary and Secondary School Student Status: Where a student studies abroad, relevant procedures shall be completed at the current school on the strength of valid certificates.
2. Croatian Laws
(a) Family Law of Croatia: Parties to a foreign-related marriage shall submit legally authenticated identity and marital status certificates. Those meeting the registration conditions shall complete registration at the local marriage registration authority and be issued a marriage certificate.
(b) Aliens Act of Croatia: A foreign national who has contracted a legal and valid marriage with a citizen of the Republic of Croatia may apply for a temporary residence permit for the purpose of family reunion; the applicant’s minor children may apply for residence status simultaneously as dependent applicants.
(c) Primary Education Act of Croatia: Minor foreigners legally residing in Croatia enjoy the equal right to compulsory education as citizens of the country, and may apply for enrollment at the corresponding school in their place of residence on the strength of legal residence certificate, birth certificate and original school status materials.
V. Authoritative Practical Recommendations Based on the Experience of This Case
Combined with years of practical experience of Guozun’s Croatia Office in the field of cross-border marriage and family law in Central and Eastern Europe, the following three professional recommendations are put forward for Chinese citizens planning to go to Croatia for marriage and settlement:
1.Pre-compliance of documents to avoid repeated corrections: Sort out all materials related to identity, marriage and children in advance, and prioritise the completion of domestic notarization and consular authentication. Remarried persons shall ensure that the divorce certificate is an effective legal document and the custody ownership documents are clear and complete, so as to avoid application rejection due to documents failing to meet local requirements.
2.Overall planning of the full process with reserved buffer cycles: There is a clear sequential logical relationship among marriage registration, residence application and children’s school enrollment. It is recommended to formulate a complete timetable in advance and reserve buffer periods for the approval of each link, so as to avoid delays in the overall settlement plan and the child’s school enrollment time node due to the delay of a single link.
3.Relying on local professional services to improve handling efficiency: There are many localised rules in Croatia’s marriage, immigration and education policies, as well as regional implementation differences. It is recommended to entrust institutions with dual-jurisdiction service capabilities in China and Croatia to follow up the whole process, and rely on local resources to liaise with administrative authorities, accurately grasp policy requirements, and improve the success rate and efficiency of handling.
