One flat, twenty applicants and a form that decides who gets the offer: the tenant's self-disclosure form is now part of almost every rental application. Anyone filling it out is under pressure. Anyone evaluating it wants to know whether the rent will arrive at the end of the month.
So what happens if someone lied on this application form? Can the landlord terminate the tenancy agreement? Can they even rescind it retroactively? And does that apply to every false statement – or only to certain ones?
The answer hinges on a preliminary question that many skip: was the landlord even allowed to ask this question? Because only permissible questions must be answered truthfully. In the case of inadmissible questions, a false answer has no consequences.
Note: This post explains the legal situation in general and does not replace legal advice in individual cases. Whether a contestation or termination is effective in your situation depends on details that can only be assessed after reviewing the documents. Have your case reviewed before you make a statement or respond to a termination.
Which questions the landlord is allowed to ask – and which not
The landlord is not permitted to ask everything. They may ask what they have a legitimate interest in, and that is essentially a single question: Will the rent be paid? Everything that has nothing to do with this question is taboo.
Under data protection law, the self-disclosure is based on Article 6(1)(b) and (f) of the General Data Protection Regulation (GDPR). The Conference of the Independent Data Protection Authorities of the Federation and the Länder (DSK) has its Guidance on obtaining self-assessments from prospective tenants published in January 2026 in a revised version (Version 2.0). It is not legally binding, but forms the benchmark against which the regulatory authorities measure practice.
New and practically important is the clear grading according to three points in time. What may be asked depends on how far advanced the application is.
- At the viewing: Only surname, first name and address are permitted. Information on financial circumstances is generally not required at this stage – and is therefore not permitted. The landlord may check identity by the presentation of an identity card; making a copy of the identity card is not required according to the guidance and is therefore not allowed.
- Following the declaration of intent to rent the flat: Now a pre-contractual obligation is created, and the permissible range of questions becomes wider. Allowed are, amongst other things, the number of persons moving in, occupation and employer, as well as the amount of the net income and the sum available for rent after deduction of current liabilities.
- After deciding on a particular candidate: Only now may proofs be requested, such as a copy of a payslip, bank statement or income tax assessment – in each case with unnecessary information redacted.
Even within the permissible phase, not everything is allowed. Some delimitations from the guidance note will surprise even experienced landlords:
- It is permissible to enquire whether consumer insolvency proceedings have been opened and are still ongoing. Here, the prospective tenant has a duty to disclose, because the attachable assets belong to the insolvency estate.
- The question regarding eviction lawsuits due to rent arrears in the past five years is permissible., provided that the proceedings resulted in an eviction order. The time frame is crucial: old, concluded cases say nothing about future solvency.
- The question regarding the duration of the employment relationship is inadmissible. It is permissible to ask about occupation and employer, but not about length of service – in a mobile labour market, this says nothing about the stability of one’s income.
- The question regarding nationality is inadmissible. It is not required for the purposes of assessing creditworthiness. Religion and ethnic origin are special categories of personal data under Article 9(1) of the GDPR; their processing is, in principle, prohibited.
- Questions about criminal records and ongoing investigations are inadmissible, regarding marriage plans, pregnancy and the desire to have children, as well as membership of political parties or tenants’ associations.
- Also inadmissible is the question regarding the contact details of the previous landlord. Furthermore, the former landlord is not obliged to issue a certificate confirming that there are no outstanding rent arrears (Federal Court of Justice, judgment of 30.09.2009, ref.: VIII ZR 238/08It cannot therefore be coerced.
Another point raised in the guidance concerns the forms themselves: a blanket declaration of consent included in the self-disclosure form is not an appropriate measure. Anyone who makes the tenancy agreement conditional on consent creates a dilemma – and in that case, the consent is not freely given under Article 7(4) of the GDPR and is therefore invalid.
The so-called right to lie
From the distinction between permissible and impermissible questions follows a rule that is central for tenants: an impermissible question does not have to be answered, and giving a false answer to it provides grounds for neither a right to contest the contract nor a right to give notice. Anyone asked about their religion or a planned pregnancy is allowed to remain silent – or answer falsely – without any subsequent consequences being derived from it.
In practice, however, this also means that anyone who leaves such fields blank is often eliminated from the selection process in a competitive housing market. That is the unsatisfactory reality behind what is, in principle, a clear legal situation. And be careful with the format: a slash through a field is routinely interpreted in practice as a negation, i.e. as an answer. Anyone who does not want to answer is better off leaving the field completely blank.
Rescission on the grounds of fraudulent misrepresentation: Section 123 of the German Civil Code (BGB)
What fraudulent misrepresentation means – in simple terms
Fraudulent misrepresentation means: someone deliberately created a false impression in order to get a signature they would not have got otherwise. It is not enough that a statement turned out to be false afterwards. The deceiver must have known it was false – or asserted it recklessly. And the deceived party must have concluded the contract precisely because of it.
If this is the case, the landlord can revoke their declaration of intent according to Section 123(1) of the German Civil Code (BGB) challenge. The episode is in Section 142(1) of the German Civil Code (BGB)The contract is then considered void from the outset. Not as of tomorrow, but retroactively – as if it had never existed.
The time limit: one year from the date of discovery
The challenge must be lodged in accordance with Section 124(1) of the German Civil Code (BGB) be declared within one year. This period does not begin with the conclusion of the contract, but, pursuant to Section 124(2) sentence 1 of the German Civil Code (BGB), at the time when the person entitled to avoid the declaration discovers the deception. A mere suspicion is not sufficient for this. The absolute limit is Section 124(3) BGB: avoidance is excluded ten years after the declaration of intent has been made.
For landlords, this means: anyone who only finds out years later through a credit check that the information provided at the time was incorrect has one year from that point onwards. Anyone who, on the other hand, stands by and watches for half a month—even though they know—risks not only the expiry of the deadline, but also the argument that the information was apparently not important to them, and therefore not causal for the conclusion of the contract.
Is that still possible if the tenant has long since moved in?
For a long time, there was controversy as to whether a tenancy agreement that had already been performed could still be challenged at all, or whether the provisions governing termination, as a more specific rule, took precedence. In its judgement of 6 August 2008 (Case No.: XII ZR 67/06), the Federal Court of Justice ruled that a challenge on the grounds of fraudulent misrepresentation is admissible even after the premises have been handed over, in addition to termination, and that, pursuant to Section 142(1) of the German Civil Code (BGB), it has retroactive effect from the date the contract was concluded.
Important for context: This decision concerned a commercial lease. The Federal Court of Justice has not ruled on the matter in the same way for residential tenancy. The lower courts mostly apply these principles to residential property as well, but anyone relying on this should be aware that there is a genuine litigation risk here.
Termination: summary or standard?
In addition to rescission, the landlord also has the option of termination. Here, a distinction must be made between two provisions that are often confused in practice.
Summary dismissal following Section 543(1) of the German Civil Code (BGB) requires an important reason: considering all circumstances, it must be unreasonable for the party giving notice to continue the tenancy. A deliberate deception regarding creditworthiness can constitute this important reason because it strains the relationship of trust right from the start. However, this does not happen automatically – it remains a matter of balancing interests on a case-by-case basis.
The summary dismissal for rent arrears pursuant to section 543(2) sentence 1 no. 3 of the German Civil Code (BGB) is something different. It applies if the tenant is in arrears with the rent, or a not inconsiderable part of it, for two consecutive due dates, or if arrears amounting to two months' rent accumulate over a longer period.
The difference is worth hard cash to tenants. After § Section 569 (3) no. 2 BGB does a summary termination based solely on default of payment become void if the arrears are paid off in full no later than two months after service of the eviction action. This so-called Grace period payment however, this only remedies the termination for default. A termination that is additionally based on fraudulent misrepresentation remains unaffected.
The ordinary cancellation to Section 573(2)(1) of the German Civil Code (BGB) is the third way. It requires a culpable, not insubstantial breach of contractual obligations and operates with a statutory notice period. It is the milder measure – and is therefore often more defensible where the threshold of unreasonableness for summary dismissal is not met.
Comparison of the three ways
| Criterion | Rescission (Section 123 BGB) | Summary dismissal (§ 543 Abs. 1 BGB) | Ordinary cancellation (Section 573(2)(1) of the German Civil Code (BGB)) |
|---|---|---|---|
| Prerequisite | Deliberate misrepresentation of a fact lawfully enquired about, which was a determining factor in the conclusion of the contract | Good cause; continuation unreasonable after weighing all circumstances | culpable and not insubstantial breach of duty |
| Effect | Contract void from the outset (Section 142(1) of the German Civil Code (BGB)) | Termination with immediate effect upon receipt | Termination upon expiry of the statutory period |
| Landlord's deadline | One year from discovery, at the latest ten years after conclusion of the contract (Section 124 of the German Civil Code (BGB)) | No rigid deadline; prolonged hesitation argues against unreasonableness | No rigid deadline; the breach of duty must still be ongoing |
| Healing through back payment | No | Only in the case of termination solely on the grounds of default pursuant to Section 569(3)(2) of the German Civil Code (BGB) | No |
| Typical risk | Not yet conclusively clarified by the highest court for residential property | The balancing of interests can go against the landlord | materiality threshold is not met |
Two judgements, two contrasting outcomes
Munich Local Court: Eviction despite back payment
The most well-known case on this subject comes from the Munich Local Court (judgment of 30.06.2015, ref.: 411 C 26176/14). In May 2013, a married couple rented a detached house in Grünwald near Munich for 3,730 euros per month. In the self-disclosure form, the tenant stated an annual income of over 120,000 euros as a self-employed person, and his wife over 22,000 euros as an employee. Both stated that in the last five years there had been no payment proceedings, enforcement orders, and no proceedings for submitting an affidavit.
Payments were only ever made after a reminder from the beginning. When the rent for September and October 2014 was not paid, the landlords gave notice of immediate termination on 23.10.2014. A credit check subsequently revealed that unsatisfied enforcement proceedings had been pending against the tenant since 1994 and that he had sworn an affidavit in October 2012.
The tenants paid the arrears in full and remained in the flat. The court nevertheless upheld the eviction claim: the notice of termination was based not only on the late payment but also on the deliberately false information provided in the self-declaration. It was precisely for this reason that the subsequent payment could not remedy the situation. The Regional Court dismissed the tenants’ appeal.
One point that is often overlooked in many accounts is that this is a local court judgement. It illustrates the legal position, but is not binding on any other court.
Giessen Magistrates’ Court: False statement acknowledged, but dismissal still invalid
That things can also turn out differently is shown by the Gießen Local Court (judgment of 23.03.2022, ref.: 42 C 273/21). A tenant had stated in the self-disclosure form that they were in employment with a net income of 2,200 euros, even though the employment relationship had already ended before the contract was concluded. The landlords gave notice of termination without notice and sued for eviction.
The court dismissed the claim. For a good cause pursuant to Section 543(1) of the Civil Code (BGB), the false statement alone is not sufficient; the decisive factor is the balancing of interests. In this case, the rent could be paid in full by the second tenant, and the tenant had long since been back in work at the time of the notice of termination, with a comparable income. The financial risk that the self-disclosure is intended to protect against had therefore not materialised at all.
Taken together, these two decisions form the actual rule of thumb: it depends on whether the misrepresentation actually had an impact on the tenancy.
What you, as a tenant, should do now
- Have it checked whether the question was admissible at all. If the false statement related to something which the landlord was not at all entitled to ask about, the notice of termination is invalid. This is the first – and often the most effective – defence.
- Check the landlord's deadlines. In the case of a challenge: When did he become aware of the matter, and was that more than a year ago? In the case of termination: How long did he wait after he became aware of it?
- Pay attention to the grounds given for the termination. If it relies solely on late payment, a full back-payment can render it ineffective. If it also cites the incorrect self-disclosure, paying alone will not help.
- Don't sign anything that looks like a Cancellation agreement looks. Anyone who moves out voluntarily loses the opportunity to have the validity of the notice reviewed by a court.
- On a Court representation in landlord/tenant disputes react. If there is no defence, a default judgment will be issued. The deadlines in eviction proceedings are short.
What you should consider as a landlord
- Adapt the questionnaire to the orientation guide from January 2026. Questions you were not allowed to ask later carry no weight regarding dismissal – and can additionally have data protection consequences.
- Act swiftly after discovery. Both the one-year period under Section 124 of the Civil Code (BGB) and the balancing of interests under Section 543(1) of the Civil Code (BGB) work against the person who waits too long.
- To justify the dismissal properly. Anyone who explicitly makes deception a ground for termination in addition to payment default deprives the grace-period payment of its effect. Exactly this point decided the Munich case.
- Check whether the deception had an effect. If the tenant pays reliably or if a co-tenant can cover the rent, the balancing act becomes difficult – as was the case in Gießen.
- Delete applicant data. Application documents of candidates with whom no contract is concluded must be deleted in accordance with Article 17(1)(a) of the GDPR, regarding claims under Section 21 of the General Equal Treatment Act (AGG) as a rule after six months at the latest. The maintenance of blacklists is not permitted.
Frequently asked questions
Do I actually have to fill out the tenant self-disclosure form?
There is no legal obligation to do so. The landlord cannot force you to sign the form. The practical situation is different: anyone who refuses to provide the information will regularly not make the shortlist in tight housing markets. A sensible middle ground is to answer the permissible questions fully and truthfully and leave impermissible fields blank. Remember that a slash can be understood as a negation – it is better to leave the field empty rather than crossing it out.
May I lie in response to an inadmissible question?
Yes. A question that the landlord was not permitted to ask does not justify an obligation to tell the truth. False statements regarding religion, nationality, pregnancy, desire to have children, criminal record or membership of a tenants' association therefore cannot support either a contestation pursuant to Section 123 of the German Civil Code (BGB) or a termination. In the case of permissible questions – income, occupation, employer, ongoing insolvency proceedings, eviction order due to rent arrears from the last five years – the opposite applies: here the information must be correct.
How long does the landlord have to contest the tenancy agreement?
One year from the time he discovered the deception (Section 124(1), sentence 1 of the German Civil Code (BGB)). The decisive factor is actual knowledge, not mere suspicion and not the conclusion of the contract. This can mean that a challenge is still possible years after moving in – for example, if a credit check only reveals the old false information. The absolute limit is ten years from the submission of the declaration of intent (Section 124(3) BGB).
I have paid the arrears of rent. Does that mean the notice of termination is off the table?
That depends on what the termination is based on. Summary termination for rent arrears becomes ineffective under Section 569(3) no. 2 of the German Civil Code (BGB) if you pay off the arrears in full at the latest two months after the eviction lawsuit is served. However, if the termination letter also cites a false self-disclosure as a reason, the subsequent payment has no effect on this second ground for termination. This is precisely what the tenants in the Munich proceedings failed on, even though they had paid everything afterwards.
Does someone commit a criminal offence if they lie on a self-certification form?
As a rule, this is restricted to civil law consequences: contestation, termination, eviction and, where applicable, damages. Criminal liability for fraud pursuant to Section 263 of the German Criminal Code (StGB) is only considered if financial loss has also occurred and the deceiver intended from the outset not to pay the rent. Whether these conditions are met can only be assessed based on the circumstances of the individual case.
Is the landlord allowed to request a SCHUFA credit check?
Only to a limited extent. According to the guidance, only credit assessment documents that are specifically created for the renting of residential property and contain only the necessary information may be requested. The comprehensive information pursuant to Article 15 of the GDPR, which you can obtain about yourself from a credit agency, must not be demanded by the landlord – it contains significantly more information than necessary. A credit check initiated by the landlord themselves is inadmissible if sufficient credit assessment documents are already available.
If you have received a notice of termination or wish to issue one
The decision rarely hinges on whether a lie was told. It hinges on three other points: whether the question was permissible, whether the deception was causal to the conclusion of the contract, and whether it had any effect at all during the ongoing tenancy. These three points can usually be assessed quite quickly on the basis of the tenant information form, the tenancy agreement and the notice of termination.
