Evidence of identity and the tiered model

Using the graduated evidentiary model, we assess which accessible and reasonably obtainable evidence can establish your identity in naturalisation proceedings. Some people have a current national passport, while others have only older certificates or had to flee without papers. The tiered model establishes which evidence takes priority in naturalisation proceedings and when other forms of evidence may be used. It combines a reliable assessment with the possibility of establishing identity even where there are substantial obstacles to obtaining documents.

Under § 10(1) StAG, naturalisation requires identity and nationality to have been established. However, the law does not contain an exhaustive list of documents that must be used to prove identity. The tiered model ranks the available methods of proof by priority, taking into account which evidence can actually and reasonably be obtained.

The model initially answers a question about the type of evidence: what kind of evidence may form the decisive basis? This must be distinguished from the question of evidential value: is the particular document submitted actually convincing? A document submitted at the correct tier may nevertheless be insufficient, for example because it cannot be clearly linked to the person or because there are substantial doubts about its contents.

The tiered model is therefore neither a simple catalogue of documents nor a points system. Several weak documents do not automatically amount to strong evidence. Conversely, an authority must not insist exclusively on an unobtainable passport if the conditions for another method of proof are met. The overview Identity and existing nationality explains the fundamental importance of this assessment.

For ongoing proceedings, the documents listed in an older checklist are therefore not the sole determining factor. An identity card mentioned there remains a possible form of evidence, but no longer automatically ranks alongside a passport. The current order for proving identity is:

1. A passport, usually the national passport of the country of origin.

2. A recognised passport substitute or another official identity document bearing a photograph.

3. Other suitable official documents.

4. Unofficial documents and other admissible evidence, particularly witness testimony.

5. Exceptionally, the applicant’s own statements following a comprehensive overall assessment.

This change is a development in judicial interpretation, not a new statutory passport requirement with its own application deadline. It must be distinguished from the 2024 reform of the nationality legislation. The general acceptance of multiple nationality has not abolished the requirement to establish identity, nor does it explain the new number of evidence tiers. For certain older applications, § 40a StAG likewise only preserves more favourable earlier rules on subsistence; it does not enshrine an older model for establishing identity.

A national passport generally contains the state’s confirmation of key personal details and nationality. It links these details to a photograph and other security features. This explains its priority. Anyone who holds a suitable passport must, in principle, present it; anyone who can reasonably obtain one cannot resort to weaker evidence merely for convenience.

However, even a passport is not irrefutable proof of the truth. Its authenticity, its connection to the person and the accuracy of the information it contains are separate questions. Where there are specific indications of errors or an unreliable issuing procedure, additional checks may be necessary. Conversely, not every abstract possibility of an inaccuracy justifies unlimited further demands. The article Passport as the primary evidence explains this distinction in detail.

If no passport is available and obtaining one is objectively impossible or subjectively unreasonable, a recognised passport substitute or another official identity document bearing a photograph may be considered. Typical examples include a personal identity card or a national identity card. They must be capable of identifying the person concerned with sufficient reliability.

A photograph alone is not enough. An official staff identity card may also contain a photograph, but it serves a different purpose and does not rank alongside a national identity card for that reason alone. The document’s function, the issuing body and the underlying verification procedure are decisive. For German travel documents, it is also necessary to examine whether the personal details were verified or merely copied.

If the second tier is also inaccessible despite sufficient cooperation, other suitable official documents may provide the necessary proof. According to case law, these include, for example, birth certificates, registration or school certificates, as well as certain documents bearing a photograph, such as driving licences or military service records. The decisive question is whether the connection between the person and the name was checked when they were issued.

An individual document often proves only part of the picture. A birth certificate, for example, records a birth and the parents, but does not directly show that the person appearing before the authority today is the child named in it. Further documents may establish this connection. A mere collection of matching details is not sufficient, however, if all the documents originate from the same unverified initial source.

If suitable official documents are also unavailable and cannot reasonably be obtained, the range expands to include other admissible evidence. This may include private documents, records from religious institutions and witness testimony. At this tier, the private origin of evidence is not a blanket reason for excluding it.

What matters is the specific basis of the knowledge. A witness who has known the person by their name since childhood can confirm different facts from someone who only learnt their date of birth from the person themselves after they arrived in Germany. For a certificate, we examine whether it relies on old records or merely a current account. The article Unofficial documents and witness testimony explains the details.

If recourse to other evidence is also objectively impossible or subjectively unreasonable, the applicant’s own account may exceptionally suffice. For this to apply, the authority must be satisfied that the statements are established after assessing all the circumstances. This final tier does not confer a right to have unverified statements accepted. Rather, it preserves a genuine opportunity to provide proof when other routes are closed.

Here too, available indications, earlier statements and the origins of any contradictions are taken into account. The authority does not have to be able to rule out mathematically the possibility that each individual detail might be false. Mere probability is not enough either, however. Further explanation is provided in The applicant’s own statements and an overall assessment where evidence is difficult to provide.

It is not enough for a particular document simply not to be in a drawer at present. The question is whether it exists or can be obtained with sufficient cooperation. “Objectively impossible” concerns practical obstacles to obtaining it. “Subjectively unreasonable” concerns burdens or dangers that the person cannot be expected to accept in their specific circumstances.

A refusal by an authority, destroyed registers or the absence of functioning state structures may prevent documents from being obtained. Specific dangers associated with making contact may make it unreasonable. A mere reference to general difficulty or a personal aversion to contacting the authorities is no substitute for this assessment. Equally, a specific danger must not be disregarded on the grounds that other applicants have managed to obtain documents.

Moving between tiers must be justified in relation to the respective types of evidence. The fact that a passport is unobtainable does not automatically answer whether an existing identity card or a register extract can be obtained. Nevertheless, the model does not require pointless repetition of measures that have no prospect of success. If the obstacles can already be reliably identified, there is no need to undertake dangerous or obviously futile attempts solely to produce evidence of them.

An existing document may be incomplete or prove only some of the personal details. The first step is then to identify which information is missing and whether it can still be reliably established at the tier concerned. A damaged personal data page, for example, presents a different problem from a fully legible document containing a contradictory date of birth. In the first case, a copy held by an authority or an obtainable replacement may help; in the second, the origins of the differing dates must be examined.

Moving to another tier requires that proof cannot be provided despite sufficient cooperation. This means neither that every existing document permanently prevents a move nor that its rejection automatically opens up the next tier. What matters is which avenues for clarification remain possible and reasonable. Existing adverse findings remain part of the overall assessment. The authority must therefore distinguish between an exhausted method of proof and a request for information that has simply gone unanswered.

The authority investigates the facts relevant to its decision. However, the applicant must cooperate fully, particularly in relation to facts from their own life history. This also requires initiative: existing documents and accessible sources of information must be identified, and reasonable steps to obtain them must be taken. The authority, for its part, has a duty to provide guidance and prompt appropriate action.

The sequence of tiers determines the priority of the principal evidence. It does not mean that supplementary information from other sources must be disregarded. An earlier school record may, for example, help explain the spelling of a name in a current document. A comprehensible family history may explain why a register extract contains a different surname.

The decisive questions are whether the information is independent and how it fits together. Three newly issued certificates copying the same unverified data set have a different evidential value from original records made at different times. Similarly, an individual discrepancy must be assessed according to its significance: a translation error calls for different treatment from an unexplained switch between completely different identities.

The sequence does not necessarily require five separate appointments or five successive applications either. Available documents can be submitted together from the outset and linked to the matters they each support. The authority must then examine which tier of evidence is legally available and which supplementary findings can be taken into account. This does not bypass any legally required assessment, but it prevents unnecessary uncertainty about information already available. Someone who holds an old register extract and a private school record, for example, does not have to conceal the second document until a decision has been made about the register extract. It remains important to make the different quality of the two sources clear.

Subject to the conditions described, difficulty in providing evidence broadens the permissible methods of proof. It does not automatically reduce the required outcome to mere plausibility. The authority must be convinced of the relevant personal details. In this respect, the court requires a practically sufficient degree of certainty, rather than unattainable absolute certainty.

If substantial doubts remain after sufficient investigation, the applicant generally bears the consequences of the facts not being ascertainable. This is not a punishment for missing documents. It means that a statutory requirement for naturalisation could not be established. Conversely, rejecting an application solely because official papers are missing, without considering an available alternative method of proof at all, would be legally flawed.

We begin the reasoning with your strongest available documents. We then address the outstanding questions and actual options for obtaining further evidence. Where an alternative evidentiary route is necessary, we explain its legal availability and exactly what each proposed piece of evidence establishes.

We also assess documents that are insufficient on their own in conjunction with the remaining evidence. Limited evidence can supplement another source. We do not fill unknown facts with assumptions: we distinguish your established information from limits of knowledge rather than creating an apparently complete story.

If you have no passport and cannot obtain one, the article Evidence where a passport is missing or unobtainable provides detailed guidance on assembling the further evidence you need. The assessment always relates to the individual person, their documents and their actual possibilities for obtaining them.
