The Short Answer

Yes — you can sue your landlord for unpaid security deposit refunds in German small claims (Mahnverfahren or ZPO §23 ff.) at the local Amtsgericht if the claim is ≤ €5,000.

What the Law Says

German law treats security deposit (Pfand) disputes as civil monetary claims under the Zivilprozessordnung (ZPO). The standard route is the simplified dunning procedure (Mahnverfahren), which applies automatically for undisputed or uncontested claims up to €5,000.

Under § 558a of the Bürgerliches Gesetzbuch (BGB), landlords must return the security deposit within a reasonable period after lease termination — typically within 3–6 months — minus lawful deductions (e.g., for repairs beyond normal wear). Deductions require itemized written justification (BGB § 558a para. 2).

If the landlord fails to act or refuses unjustifiably, tenants may initiate the Mahnverfahren under §§ 688–697a ZPO. This court-issued payment order (Mahnbescheid) becomes enforceable unless the landlord files a formal objection (Einspruch) within two weeks (ZPO § 694). If objected, the case proceeds to oral hearing before the Amtsgericht (ZPO § 695).

Statutory Text

The landlord shall return the security deposit after termination of the tenancy, after deduction of any justified claims.
