Naturalisation by legal entitlement and discretionary naturalisation

We assess whether you have a legal entitlement to naturalisation or whether your circumstances call for a discretionary decision. A second question is equally important: must the authority grant naturalisation if those requirements are met, or can it then make a further decision of its own? The answer determines the significance of individual circumstances, the documents needed and the options for challenging a refusal.

The Nationality Act provides for both routes. Naturalisation by entitlement under § 10 StAG is the main route for many people whose lives are centred in Germany. Discretionary naturalisation under § 8 StAG allows a different legal assessment of certain personal circumstances. We neither prematurely treat the separate special rules as unfettered discretion nor equate them with ordinary entitlement-based naturalisation.

A legal entitlement binds the authority to the law. If all requirements are met and no ground for exclusion exists, naturalisation must be granted. The authority may not then make an additional selection based on whether it finds the person particularly likeable, professionally interesting or economically desirable. Conversely, a persuasive motivation letter cannot replace a statutory requirement that has not been met.

Nor does citizenship arise automatically as soon as the final requirement is met. An application, the procedure and its legally effective completion are still necessary. Under § 16 StAG, naturalisation takes effect when the naturalisation certificate is delivered. This distinction matters, for example, for travel, applying for a German passport and children's position under citizenship law. The article on the naturalisation certificate and when naturalisation takes effect explains this in more detail.

§ 10 StAG generally requires five years of lawful habitual residence in Germany. Further requirements include, in particular, clarification of identity and citizenship, a suitable residence status, the statutory declarations of commitment, adequate German language skills, civic knowledge and the requirements concerning livelihood and criminal convictions. The individual requirements are explained together in the overview of requirements for naturalisation. The current version of § 10 StAG is authoritative.

These requirements should not be understood merely as a list of documents. An employment contract, for example, does not answer every question about livelihood. A residence permit may be important for earlier lawful residence but require a change of status by the time of naturalisation. The assessment therefore focuses on the person's actual circumstances and the statutory provision applicable in each case.

The possibility of naturalisation after three years on the basis of exceptional integration achievements was abolished with effect from 30 October 2025. The five-year rule in § 10 remains in place. However, this does not mean that every naturalisation under German law requires five years of residence: special provisions, such as those for spouses of German citizens, still need to be examined separately. The Federal Government confirms the date of abolition.

For ongoing proceedings, the law applicable to the decision must generally be considered. Submitting an application does not automatically preserve all earlier requirements indefinitely. However, the legislature can create transitional rules. An important example is § 40a StAG: for applications submitted by 23 August 2023, the version in force before 27 June 2024 applies to livelihood where it is more favourable.

For an older application, we examine the receipt date, procedural history and the particular requirement that changed together. This allows us to assess the effect of a legal change on your pending application rather than applying only a current general checklist. We explain the details in the former three-year rule and changes in the law affecting pending applications.

Discretionary naturalisation gives the authority scope to make a decision. Nevertheless, it is not a route without requirements. § 8 requires lawful habitual residence in Germany, clarified identity and citizenship, and capacity to act in the procedure or legal representation. There are also statutory requirements concerning convictions, accommodation and the ability to support oneself and one's family members. § 8 StAG distinguishes these requirements from the exceptions expressly permitted.

If the necessary requirements are met, the initial result is an entitlement to a lawful exercise of discretion. The authority must assess the individual case on an accurate factual basis and observe the statutory limits. It must neither ignore its discretion nor exercise it according to irrelevant criteria. Constitutional requirements, particularly equal treatment, limit that discretion.

Factors that may matter to the decision include the duration and nature of residence, language skills, personal and family circumstances and particular public interests. The fact that language or a particular period of residence does not appear as a separate numbered requirement in the wording of § 8 therefore does not mean that it is irrelevant. Such factors are considered when discretion is exercised.

§ 8 paragraph 2 does not allow the requirement to clarify identity to be waived. However, missing papers do not lead to exclusion without further examination: a five-stage evidential model applies. Depending on unsuccessful reasonable efforts to obtain documents, other official documents, further evidence and, exceptionally, the person's own statements may be considered alongside a passport. These stages do not offer a free choice. Details are explained in Clarifying identity and citizenship.

Particular hardship cannot be established solely by the understandable wish to have a German passport. The specific circumstances and their legal significance are decisive. Where there is a lasting impairment of health, for example, its effects on the ability to work, the person's background and the consequences of refusing naturalisation may need to be considered together. The existence of a diagnosis does not fully answer these questions.

We check whether a medical certificate clearly describes the significant limitations and whether benefit decisions and household information establish the financial position. A large collection of disorganised documents is less informative than a clear account showing which fact answers which legal question. The detailed article on particular hardship in discretionary naturalisation explores this distinction more fully.

Between a mandatory entitlement provision and an ordinary discretionary provision lies a “should” provision (Sollvorschrift). Under § 9 StAG, spouses and registered civil partners of German citizens should be naturalised if the statutory requirements are met. In the typical case, there is a strong legal obligation in favour of naturalisation. A departure requires atypical circumstances; it is not a matter of freely deciding what seems expedient.

The provision generally requires three years of lawful habitual residence in Germany and a marriage or registered civil partnership that has existed for two years. The other requirements follow from the statutory cross-references. Marriage alone neither makes a person German nor replaces the naturalisation procedure. Having a German spouse also does not automatically provide access to this domestic route where the person is habitually resident abroad. § 9 StAG is the relevant provision.

§ 10 paragraph 2 contains another mixed situation: subject to the statutory requirements, spouses, registered civil partners and minor children may be naturalised together with the main applicant even though they have not yet completed five years of residence. One person's entitlement therefore does not automatically extend to the whole family. The correct legal basis must be identified for each family member.

Two age limits must be distinguished here: a child is a minor until their 18th birthday; under § 34 StAG, they can generally take procedural steps on their own behalf from the age of 16, unless the exceptions specified there apply. For the simplified assessment of language skills, by contrast, what matters is whether the child is still under 16 at the time of naturalisation. An early application does not preserve that age threshold.

Before comparing § 8 and § 10, we assess whether another legal basis takes priority. For acquisition by birth, proof of existing status may be sufficient. Earlier gender-discriminatory rules can give rise to a right of declaration under the conditions of § 5 StAG. Where the family history points that way, we therefore first clarify “Already German without naturalisation?”.

For people persecuted under National Socialism and their descendants, independent entitlements exist under Article 116 paragraph 2 GG and § 15 StAG. These follow different requirements from ordinary naturalisation within Germany. Former Germans whose lives are centred abroad, by contrast, may fall under § 13; other cases abroad may fall under § 14. The articles on renaturalisation and naturalisation from abroad and restitution under citizenship law explain these routes.

We base the legal reasoning of your application on your actual circumstances. Someone who meets the requirements for an entitlement under § 10 does not also have to prove an exceptional state interest in their naturalisation. In a discretionary decision, by contrast, precisely those circumstances that an ordinary document checklist does not cover may be decisive. These include, for example, former German status or a specifically substantiated case of particular hardship.

We handle the legal classification; we need you to provide the relevant facts fully and accurately. Where several legal bases genuinely apply, we make clear that the application must also be considered from those perspectives. If circumstances such as residence or income change during the procedure, we reassess their effect on the application.

In a dispute concerning naturalisation by entitlement, the main question is whether the statutory requirements are met. If they are and the case is ready for a final decision, a court can order the authority to grant naturalisation. In discretionary naturalisation, by contrast, the court generally reviews the lawfulness of the exercise of discretion. It does not simply replace the authority's decision with its own view of whether naturalisation would be appropriate.

An error may lie, for example, in the authority failing to recognise its discretion at all, overlooking decisive facts or relying on irrelevant considerations. A successful legal action then often leads to a fresh decision that takes account of the court's legal assessment. Only where a positive decision is the sole legally permissible outcome can discretion exceptionally narrow to that one possibility. The scope of judicial review is described in § 114 VwGO.

The assessment of a refusal therefore depends on its specific reasoning. The heading “discretionary naturalisation” does not make a decision immune to challenge; an existing legal entitlement does not remove the need to examine the facts. The article on actions to compel a decision and review of discretion explores these differences further.
