Legal effect

Res judicata - Res judicata refers to the finality and binding nature of a judicial or administrative decision. A final decision can no longer be challenged through ordinary legal remedies and is binding on the parties involved. In real estate law, res judicata is particularly relevant in the context of building permits, foreclosure orders, land registry decisions, and judgments in disputes concerning tenancy or neighbor law.

Formal and Substantive Res Judicata

Formal res judicata occurs when the appeal period has expired or an appeal has been waived. A judgment by a local court becomes formally final if no appeal is filed within one month. Substantive res judicata means that the matter in dispute cannot be re-litigated between the same parties. In the case of administrative acts (e.g., building permits), the term finality is used: The building permit becomes final when the one-month objection period has expired and no objection has been filed.

The distinction between formal and substantive res judicata has practical significance: Formal res judicata is the prerequisite for substantive res judicata. Once a judgment is formally final, the facts and legal consequences established therein can no longer be challenged in new proceedings between the same parties. This also applies to default judgments, provided no admissible objection has been filed, and to judgments based on admission. In enforcement proceedings, the formal res judicata of the enforceable title is a prerequisite for the enforcement clause and thus for the actual enforcement measure.

Res judicata in real estate law

In the real estate sector, res judicata has practical consequences: A final and binding award decision in a foreclosure auction results in the transfer of ownership-even if the previous owner objects. A final and binding building permit gives the builder certainty that their project can no longer be revoked by the authorities (exception: revocation in case of illegality). A final eviction judgment enables the bailiff to carry out the eviction. Finality protects the beneficiary from further challenges regarding the same matter.

In rental disputes, a judgment ordering eviction and surrender of the property becomes final after the appeal period has expired (usually one month after service). The landlord can then instruct the bailiff. Especially in Nuremberg, where-as in other major cities-an active rental market leads to numerous disputes, it is important for landlords to be aware of the appeal deadlines: Anyone who has obtained a judgment in their favor should not wait unnecessarily-the enforcement clause should only be applied for after the judgment becomes final.

In administrative law, the finality of a building permit does not provide the builder with absolute protection: If it turns out that the permit is based on false information provided by the builder or violates mandatory law, the authority may revoke or rescind it pursuant to Sections 48, 49 of the Bavarian Administrative Procedure Act (BayVwVfG). A building constructed in good faith still enjoys protection of legitimate expectations, which may result in a duty to pay compensation.

Finality of Land Registry Decisions

Land registry entries do not become “final” in the traditional sense, but they enjoy public faith (Section 892 BGB): Anyone acting in reliance on the accuracy of the land register is protected. An erroneous entry can only be corrected through an application for correction of the land register if the affected party proves the inaccuracy. Between the filing of the application and the correction, a notice of objection (Section 899 BGB) protects against acquisition in good faith by third parties.

The Land Registry decides on applications through land registry decisions, which-if they are disadvantageous to the applicant-may be challenged by filing an appeal (§ 71 GBO). If the appeal is rejected, a further appeal against the decision of the Regional Court may be filed with the Higher Regional Court. Only once all legal remedies have been exhausted or the deadlines have expired does the Land Registry Office’s decision become final. In practice, land registry decisions are rarely the subject of lengthy appeals-when the legal situation is clear, applications are decided upon quickly.

Practical Tip for Property Owners in Nuremberg

We recommend that owners and buyers in the Nuremberg metropolitan region actively monitor the legal finality of decisions. Anyone who has received a building permit should wait to begin construction until the neighbor objection period (1 month from service on the neighbors) has expired-or at least assess the risk of a neighbor objection. In the case of foreclosure auctions at the Nuremberg Local Court, the auction award decision generally becomes final 2 weeks after the auction date, provided no motion to vacate the award is filed. Only then should financing be secured and planning begin.

For landlords who wish to pursue foreclosure after winning an eviction lawsuit, we recommend: Have the court certify that the decision is final and immediately instruct the bailiff if the tenant does not vacate the apartment voluntarily. Every month of delay means further loss of rent. In Nuremberg, processing times at the local court and with the bailiff must be factored into your planning realistically.

Frequently Asked Questions

When does a building permit become final?

A building permit becomes final if none of the affected parties (especially neighbors) have filed an objection within the one-month appeal period starting from the date of service. If the neighbors were not formally notified, an extended period of up to one year begins upon the start of construction. In Bavaria, the objection period is also one month for the builder and one month for neighbors starting from the date the permit is served.

Can a final decision be reversed?

Generally, no-that is, after all, the point of finality. However, there are narrow exceptions: A reopening of proceedings is possible in the case of judgments if evidence subsequently emerges that would have altered the outcome (Section 580 of the German Code of Civil Procedure (ZPO)). A final administrative act (e.g., a building permit) may be revoked under strict conditions if it was unlawful (Section 48 VwVfG)-the beneficiary may then have claims for compensation. In land registry law, an entry can only be corrected through rectification.

What does finality mean for land registry entries?

Land registry entries do not become “final” in the traditional sense, but they enjoy public faith (Section 892 BGB): Anyone acting in reliance on the accuracy of the land registry is protected. An erroneous entry can only be corrected through an application for land registry correction if the affected party proves the inaccuracy. Between the filing of the application and the correction, a notice of objection (§ 899 BGB) protects against acquisition in good faith by third parties.

What practical steps follow once an eviction judgment becomes final?

Once the eviction judgment becomes final, the landlord applies to the court for an enforceable copy of the judgment. This is submitted, together with the certificate of finality, to the bailiff, who sets a date for the eviction. The tenant receives a notice; if the tenant remains in the apartment despite this, forced eviction takes place. In principle, the landlord can recover the costs of enforcement from the tenant, although actual recovery depends on the tenant’s assets.
