We assess with you whether inaccurate information involves a wrong date, an incomplete answer or deliberate deception; legally, these are different situations. In a naturalisation procedure, information must be accurate and changes relevant to the decision must be communicated clearly. When an error is discovered, its content, how it arose and the stage of the procedure all matter. In addition to rejection, intentional deception can lead to criminal proceedings, a ten-year bar to naturalisation and, if naturalisation has already taken place, its revocation.

First distinguish between an error, missing evidence and deception

Information is incorrect if it does not correspond to the actual circumstances. An answer may be incomplete if a significant part of the facts asked about is missing. This must be distinguished from accurate information for which the required evidence is not yet available. A missing official document does not automatically turn a truthful statement into a lie, but may prevent a necessary requirement from being established.

Nor is a typing error necessarily intentional deception. Transcription errors, different transliterations of a name or misunderstandings when completing a form must be clarified. The mere fact that two documents differ is not the only consideration. The cause, the person's knowledge and the significance of the discrepancy for the naturalisation decision are important.

A correction does not automatically remove all consequences

Successfully correcting information and legally assessing the original statement are two different questions. The authority needs the correct facts to decide the application. In addition, it may be necessary to examine whether an earlier statement was deliberately false. A later correction does not automatically undo a criminal offence already committed or a bar that has been determined.

Which information may be particularly relevant to the decision?

The statutory requirements for naturalisation are central. These include, in particular, identity and citizenship, periods of residence and residence status, the ability to support oneself, family circumstances, required knowledge and possible grounds for exclusion. The relevance of a piece of information depends on the basis on which naturalisation is sought.

Undisclosed income may have a different significance from an undisclosed employment relationship which, in reality, does not exist at all. A misspelling of an employer's name must be assessed differently from invented employment. For naturalisation as the spouse of a German citizen, the actual continuation of married life together may also be decisive. It is therefore not enough to treat all discrepancies indiscriminately as either irrelevant or deceptive.

For criminal information, we distinguish convictions, pending proceedings, register responses and statutory limits on use. A certificate of conduct showing no entries does not automatically answer every question in a naturalisation application. § 12a(4) StAG contains an express duty to disclose foreign convictions and investigations and criminal proceedings pending abroad. The article on certificates of conduct, registers and disclosure duties explains this in more detail.

Information must remain accurate throughout the procedure

Processing an application may take some time. During that period, employment, income, marital status, address or circumstances relating to criminal matters may change. A statement that was correct when the application was made does not become retrospectively false because of a later change. Nevertheless, an update may be required so that the authority does not decide on a factual basis that has become outdated.

For duties to cooperate, § 34 StAG refers to § 82 Residence Act. The required evidence and personal information must therefore be taken seriously throughout the ongoing procedure. Which changes are legally relevant depends on the particular application. A change of job may, for example, require new evidence of income; separation may be significant for a special family-based route to citizenship.

Different names for benefits must not lead to factually incorrect answers either. The SGB II benefit has been called Grundsicherungsgeld since 1 July 2026; authorities may continue to use the term Bürgergeld until the end of 2026. When asked about SGB II benefits, what matters is the benefit actually received. The change of name does not affect the duty to state accurately that a benefit is being received. The basis is §§ 19 and 65a SGB II in the official compilation published by the Federal Employment Agency.

Correcting a discovered error clearly

For an ordinary mistake, our correction clearly identifies the earlier statement and the accurate version. Simply replacing an attachment without explanation may create new uncertainty. It is advisable to clearly identify the application and the document already submitted, and provide suitable supporting evidence.

Structuring a correction clearly

We structure a factual correction around the following information:

  • the specific answer or document affected;

  • the correct fact and, where relevant, the correct period;

  • a clear explanation of the cause of the discrepancy;

  • the evidence attached or an explanation of when it can be supplied;

  • an indication of whether the correction also affects any other information.

We clarify with you how the error actually arose and do not present a suspected explanation as established fact. If a date still needs checking, we make that need clear. We retain earlier versions and transmission evidence. This allows you to reconstruct later what was stated, when it was stated and when it was corrected.

Discrepancies concerning identity often require more than a brief correction to a form. Previous passport details, register entries and translations may need to be considered together. The article on correcting different names, dates of birth and earlier information provides further guidance.

When intentional deception is suspected

A different approach is needed if the authority has already alleged deception, manipulated documents are involved or a criminal investigation is threatened. Cooperation in the naturalisation procedure and the rights of a person accused of an offence must then be considered together. A detailed spontaneous statement may have factual or legal consequences extending beyond the original issue.

Before a comprehensive statement is made, we examine the specific allegation, previous declarations and the protection of your procedural rights. This can involve organising the statements already submitted, the authority's file and the specific allegations. It is not a reason to make further false statements or alter documents. Its purpose is to provide an accurate account while protecting the procedural rights that apply.

The authority must also distinguish between an unresolved naturalisation requirement and proven intentional conduct. The fact that a document is unconvincing does not necessarily mean that the applicant knowingly used it to deceive. The requirements for each adverse legal consequence must be examined separately.

Criminal liability under § 42 StAG

§ 42 StAG makes certain incorrect or incomplete statements punishable by a fine or imprisonment of up to five years. It covers anyone who makes or uses such statements concerning essential naturalisation requirements in order to fraudulently obtain naturalisation for themselves or another person. The provision therefore does not criminalise every possible mistake in a form.

In particular, there must be a connection to essential requirements and intentional conduct with the purpose described in the legislation. A merely negligent oversight is not sufficient for this offence. At the same time, the provision is not limited to the person seeking to be naturalised. Deliberately providing false information for someone else may also fall within its scope.

Naturalisation does not have to have actually taken place for § 42 to apply. The act relevant to criminal liability may already consist of making or using the false statements before the competent body. It therefore does not automatically protect against criminal proceedings if the authority detects the deception in time and rejects the application. Nor is later withdrawal of the application a statutory voluntary disclosure guaranteeing immunity from punishment.

A voluntary correction may be relevant when assessing conduct after the offence. § 46 StGB identifies such conduct as a factor in sentencing. However, this does not establish a particular sentence or promise that proceedings will be discontinued. Manipulated documents may also give rise to further offences, which must be examined independently.

The ten-year bar to naturalisation during an ongoing procedure

§ 35a StAG provides for a particularly far-reaching consequence under administrative law. Under this provision, naturalisation is excluded for ten years if, during the naturalisation procedure, the authority establishes one of the acts specified there. These include fraudulent deception, threats or bribery, as well as intentionally incorrect or incomplete statements about essential requirements that are made or used to obtain naturalisation for oneself or someone else.

For false or incomplete statements, the wording of the legislation expressly requires intent. A mere typing error therefore does not in itself trigger this bar. The authority must establish, in particular, the relevant act, its significance for the procedure and the required mental elements. A missing attachment does not automatically result in a ten-year bar to naturalisation.

In this form, the provision does not require naturalisation to have already taken place. Nor does the legislation specify a previous criminal conviction as a condition for the authority's finding. Criminal proceedings and the decision imposing a bar follow different rules. Neither the opening of an investigation nor its outcome may therefore be equated with the question of a bar without further examination.

A later improvement in personal circumstances does not remove an effective bar. Anyone who has since reached the required period of residence or obtained a genuine language certificate must also take account of the existing exclusion. A new application to a different competent authority is not a way to circumvent an effective exclusion period.

For the start of this form of bar, the legally effective decision establishing the relevant conduct is decisive. Under the general model in § 43(1) VwVfG, an administrative act takes effect in relation to the person concerned when it is notified to them; the applicable procedural law of the federal state must be taken into account. The ten years therefore do not begin with the original application or the statement in question. In this form of the bar, it is also not necessary to wait until the finding can no longer be challenged. The decision and evidence of receipt are therefore important for calculating the period.

For older events, we additionally assess the temporal applicability of the bar rule. The former possibility of having a fresh application assessed after revocation cannot be treated as a general promise of immediate renaturalisation under current law. Conversely, a statement made before the bar was introduced must not be treated in the same way as a present-day case without examining which law applies over time. The article on renaturalisation and the relevant exclusion periods provides further information.

Revocation after naturalisation has already taken place

Once the naturalisation certificate has been handed over, the matter is no longer merely a pending application. An unlawful naturalisation may be revoked under the special requirements of § 35 StAG. Among other things, the provision requires naturalisation to have been obtained through one of the dishonest means it specifies. In the case of intentionally false or incomplete information, that information must have been essential to the decision.

This establishes an important limit: not every error by the authority discovered later, and not every subsequent change in personal circumstances, justifies revocation. The unlawfulness of the naturalisation, the ground for revocation and its connection with the decision obtained must be examined. Revocation is also subject to the statutory requirements governing discretion and proportionality.

§ 35(3) limits the power to revoke to ten years after notification of naturalisation, generally from the handover of the certificate. The period does not begin only when the authority discovers the inaccuracy. This time limit must be distinguished from the bar to naturalisation. If naturalisation is revoked under § 35 and the revocation can no longer be challenged, a separate ten-year bar applies under § 35a, sentence 1, no. 1. The two periods must therefore not be combined into a single period running from the original application.

Under § 35(6), citizenship is lost retrospectively once the revocation decision can no longer be challenged. Effects on family members require separate consideration; where its requirements are met, § 35(5) requires an independent decision for each person affected. A more detailed discussion is available under fraudulently obtained naturalisation, consequences for family members and legal remedies.

A hearing, a formal decision and interim legal protection

A reference to inconsistencies is not the same as a formal decision imposing a bar. A hearing is intended to provide an opportunity to present facts relevant to the decision and clear up misunderstandings. The applicable procedural rules govern this, for example § 28 VwVfG or the corresponding state provision. We carefully examine the specific allegation and deadline.

If the authority issues a declaratory decision under § 35a, sentence 1, no. 2, an administrative objection and court action have no suspensive effect under the express wording of the legislation. The decision is immediately enforceable. Anyone wishing to prevent it from taking effect pending a final decision must therefore also have the possibilities for interim legal protection under § 80 VwGO examined.

We assess an application refusal, a bar decision and a criminal allegation separately, including their respective requirements and remedies. Different bodies, legal remedies and deadlines may apply. A simple status enquiry or general complaint does not reliably preserve a formal deadline for a legal remedy. The next step depends on which decision has actually been issued and what legal protection is sought.
