What counts as a genuine link or abuse in EU residence and citizenship cases?

Short answer

EU law has no single “genuine link” test for nationality, marriage, residence and dependency. A Member State controls acquisition of its nationality but cannot commercialise it—and EU citizenship—through an institutionalised exchange of predetermined payments or investments for naturalisation. The Court condemned Malta's scheme without prescribing a universal residence or integration test.

A marriage is not abusive merely because it gives an immigration advantage. Authorities need an individual and proportionate basis for finding fraud or a marriage of convenience. For return residence, the issue is whether the EU citizen genuinely resided in another Member State under the conditions for residence beyond three months and created or strengthened family life there. For derivative residence under Article 20 TFEU, the decisive link is practical dependency: would refusal force the EU citizen to leave the Union?

Authorities may examine artificial arrangements, but cannot replace statutory tests with stereotypes, systematic checks or a demand that every family prove its innocence.

Four different legal questions sit behind “genuine link”

The expression is used loosely, but the legal inquiries differ:

• nationality concerns the mutual trust attached to Member State nationality and EU citizenship;
• marriage cases concern fraud or abuse under Article 35 of Directive 2004/38/EC;
• retained and return residence concerns actual qualifying residence and family continuity;
• derivative residence concerns dependency severe enough to make an EU citizen leave the Union.

The evidence relevant to one category cannot simply be imported into another. A short residence may matter to a return claim but does not prove a marriage false. An economically motivated marriage may still be genuine, while an investment programme may be unlawful if its design makes nationality purchasable.

Investor citizenship: competence has EU-law limits

Nationality law is principally for each Member State. But a national of a Member State automatically becomes an EU citizen under Article 20 TFEU. Other Member States must recognise that status, so one State's naturalisation decision has Union-wide consequences.

In Commission v Malta, C-181/23, the Grand Chamber held that Malta's scheme breached Article 20 TFEU and the duty of sincere cooperation in Article 4(3) TEU. The scheme systematically offered naturalisation through a predetermined package of contributions, property commitments, donations and a relatively formal residence stage.

“A programme of that sort amounts to the commercialisation of the granting of the status of national of a Member State and, by extension, Union citizenship.” — Commission v Malta, C-181/23, paragraph 100

The judgment targets an institutionalised transactional scheme, not every investment criterion or every exercise of national naturalisation discretion. Actual residence, family life, language, social or economic participation and an intention to belong may help demonstrate a real relationship. But the Court did not convert any one factor into an EU-wide minimum or authorise the Commission to administer national citizenship law.

The question is whether naturalisation remains a public-law assessment of membership or has become a predetermined exchange. Formal discretion does not cure a transactional scheme.

Marriage: advantage does not itself establish abuse

Directive 2004/38 gives a qualifying spouse derived entry and residence rights. Article 35 permits proportionate measures necessary to refuse, terminate or withdraw a right in cases of abuse or fraud, such as a marriage of convenience. Procedural safeguards still apply.

The authority should ask whether the marriage was entered solely to obtain a free-movement right otherwise unavailable and whether the spouses intended no genuine marital relationship. Timing, separate addresses, payment or inconsistent accounts may be evidence, but no single factor decides the case. Generic profiles cannot substitute for proof.

Metock, C-127/08, closes off several shortcuts. A host State cannot require a third-country spouse previously to have resided lawfully in another Member State. The Directive applies irrespective of when or where the marriage was celebrated or how the spouse entered the host State. Those facts may be examined where there is concrete evidence of fraud, but cannot become extra eligibility conditions.

“irrespective of when and where their marriage took place and of how the national of a non-member country entered the host Member State” — Metock and Others, C-127/08, operative part

A marriage can be motivated partly by residence security and remain real. Conversely, a valid certificate does not prevent a supported finding that the relationship was manufactured exclusively to obtain rights. The decision must identify the evidence, permit a response and be appealable.

Return residence requires real qualifying residence

An EU citizen returning to the State of nationality may obtain a derived right for a third-country family member under Article 21 TFEU. In O. and B., C-456/12, the Court required residence in the other Member State pursuant to, and in conformity with, the conditions governing residence beyond three months or permanent residence. Family life must have been created or strengthened there.

Weekend visits or short stays covered only by the first-three-month rule do not ordinarily establish the qualifying residence needed for the return route. A paper address without actual life in the host State may be challenged. But motive alone is not decisive: a citizen who deliberately exercises free movement can rely on EU law where the residence and family life were real and the Directive's conditions were met.

This approach prevents an artificial journey while protecting free movement. Relevant evidence includes housing, work or self-sufficiency, required insurance, daily presence, family care and the development of family life. Registration documents are evidence, not conclusive proof.

Lounes, C-165/16, addresses a different continuity problem. An EU citizen who moved to another Member State, later acquired that State's nationality and retained the original nationality no longer fits the Directive's definition of a citizen residing in “another” Member State. Article 21 TFEU nevertheless protects the useful effect of the earlier movement and may give a spouse a derived right under conditions no stricter than the Directive. Naturalisation does not erase genuine prior movement and family life.

Retained residence follows statutory events and conditions

Articles 12 and 13 of Directive 2004/38 regulate residence after death, departure, divorce or termination of a registered partnership. A third-country family member may need to prove, for example, the duration of the marriage, residence in the host State, custody, access rights or particularly difficult circumstances such as domestic violence, and must usually meet economic conditions until permanent residence is obtained.

For a domestic-violence victim, X v Belgian State, C-930/19, allows divorce proceedings to begin after the EU-citizen spouse has left the host State; requiring an earlier filing could expose the victim to blackmail. The proceedings must nevertheless begin within a reasonable period after departure, and Article 13(2)'s economic conditions still apply.

Authorities may verify the event and evidence and examine a sham relationship or staged sequence. They cannot add a general “genuine link” requirement that displaces the Directive's criteria or defeats protections for domestic-violence victims.

The assessment should distinguish the original family relationship from the later statutory basis for retention. Relationship breakdown does not retrospectively make a genuine marriage abusive, and divorce does not automatically extinguish a right that Article 13 preserves.

Article 20 dependency is a test of practical compulsion

Article 20 TFEU creates a narrow derived right where denying a third-country family member residence would deprive an EU citizen of the genuine enjoyment of the substance of citizenship rights. The question is not whether living together is desirable, cheaper or emotionally preferable. It is whether dependency means the EU citizen would in practice be compelled to leave the Union.

In K.A. and Others, C-82/16, the Court required an individual assessment even where the applicant was subject to an entry ban. For a child, relevant factors include age, physical and emotional development, the strength of ties with each parent, actual care and the risks separation would create. Cohabitation is relevant but not indispensable. The existence of another EU-citizen parent cannot by itself end the inquiry.

For an adult EU citizen, qualifying dependency is exceptional. Ordinary emotional bonds or purely financial support normally do not make departure unavoidable. Serious health, care or incapacity facts may do so, but the evidence must show real practical necessity.

This doctrine is not ordinary family reunification. Charter rights inform the assessment, but Article 20 still depends on compelled departure from the Union.

Evidence, burden and safeguards

A proportionate investigation begins with specific indications, not systematic suspicion of international families. Relevant evidence includes residence, travel, housing, finances, communications, care, interviews and public records, assessed as a whole with innocent explanations.

A defensible decision should:

1. identify the precise substantive right and alleged artificial element;
2. distinguish missing eligibility from fraud or abuse;
3. disclose the essential case and allow the person to respond;
4. consider family life, children's interests and proportionality;
5. give reasons capable of effective judicial review.

Fraud may justify withdrawal, but loss of EU citizenship engages the Rottmann and Tjebbes proportionality principles. That review does not legitimise fraud; it ensures lawful assessment of citizenship consequences.

Conclusion

“Genuine link” is not a free-standing refusal ground. EU law instead targets transactional naturalisation, marriages of convenience, non-qualifying return residence and dependency that does not practically compel departure from the Union.

The sound method is to identify the exact right first, then test its statutory conditions, objective facts and any alleged artificial arrangement through an individual, reasoned and proportionate procedure.
