Evidence in German Civil Procedure

The ZPO Framework

Evidence in German civil procedure is governed by Sections 284-494a of the Code of Civil Procedure (Zivilprozessordnung, ZPO). German civil procedure follows the principle of party presentation (Beibringungsgrundsatz or Verhandlungsgrundsatz): the parties present facts and evidence, while the court evaluates the evidence and applies the law. The court does not investigate facts ex officio in ordinary civil proceedings (unlike in inquisitorial procedures or family matters).

Section 284 ZPO provides that evidence is taken concerning disputed factual allegations that are relevant to the decision. The court decides which facts require proof based on the pleadings; undisputed facts require no proof, and facts judicially noticed (offenkundige Tatsachen) do not require evidence. The court may also consider facts that are not in dispute if they become relevant during the proceedings.

Types of Evidence

German law recognises five means of evidence (Beweismittel): documentary evidence (Urkundenbeweis), witness testimony (Zeugenbeweis), expert evidence (Sachverstandigenbeweis), judicial inspection (Augenschein), and party hearing (Parteivernehmung). These are enumerated in Section 371-455 ZPO. The list is exhaustive; no other forms of evidence are permitted.

Documentary evidence (Sections 415-444 ZPO) is the most highly valued form. Private documents (Privaturkunden) provide prima facie evidence that the declaration contained therein originates from the signatory. Public documents (offentliche Urkunden) — official records, notarial deeds, court records — provide full proof of their content. The party relying on a document must produce the original; copies are admissible only if the original is unavailable without the party’s fault.

Witness testimony (Sections 373-401 ZPO) is the most common form of evidence. Any person capable of perception and recollection may be a witness. Witnesses are examined individually; they may not attend the hearing before their examination. The witness must be sworn (Vereidigung) unless the parties waive the oath; the court may also dispense with the oath for certain categories of witnesses (minors, persons with limited capacity, or parties to the dispute). Witness testimony is evaluated freely by the court.

Expert evidence (Sections 402-414 ZPO) is used where the court lacks specialised knowledge. The expert is appointed by the court, not by the parties, and is independent and impartial. The expert must render an opinion on questions of fact within their expertise; questions of law are for the court. The parties may suggest expert candidates, and they may challenge an appointed expert on grounds of bias. Party-appointed experts (Privatsachverstandige) are not formal means of evidence but may be heard as witnesses on factual observations.

Judicial inspection (Sections 371-372a ZPO) involves the court directly perceiving a fact through its own senses — viewing a property, examining physical evidence, listening to recordings. The court may also appoint an expert to assist in the inspection. The inspection record replaces the actual inspection for appeal purposes.

Party hearing (Sections 445-455 ZPO) is a subsidiary means of evidence: a party may be heard as a witness only if no other evidence is available or if the other party consents. The party is not sworn. Party hearing is distinguished from party interrogation (Parteivernehmung), which can be ordered by the court ex officio in certain circumstances.

Free Evaluation of Evidence

The principle of free evaluation of evidence (Grundsatz der freien Beweiswurdigung) is the cornerstone of German evidence law. Section 286(1) ZPO provides: “The court shall decide, taking into account the entire content of the proceedings and the result of any taking of evidence, at its free discretion whether a factual allegation is to be considered true or not.”

The court is not bound by formal rules of evidence. It may accept or reject any evidence based on its weight and credibility. The court must state in its judgment the reasons for its assessment. The appellate court reviews the trial court’s evaluation of evidence only for errors of law — whether the trial court violated logical rules, general principles of experience, or procedural requirements. The BVerfG reviews evidentiary decisions for violations of the right to be heard and the right to a fair trial.

Burden of Proof

The burden of proof (Beweislast) operates at two levels. The subjective burden or burden of producing evidence (subjektive Beweislast, Behauptungslast) determines which party must present evidence on a particular fact. The objective burden or burden of persuasion (objektive Beweislast, Feststellungslast) determines which party bears the risk of non-persuasion — the party that will lose if the court cannot determine the truth of a fact.

The general rule is that each party bears the burden of proof for facts favourable to their position. The party claiming a right bears the burden of proving the facts establishing the right; the party opposing the right bears the burden of proving facts that defeat or extinguish the right. For standard contract claims: the claimant proves the contract’s formation; the defendant bears the burden for defences such as performance, impossibility, or limitation.

Presumptions (Vermutungen) shift the burden of proof. Section 891 BGB presumes that the holder of an entry in the Land Register is entitled to the registered right. Section 1006 BGB presumes that the possessor of a movable thing is its owner. Statutory presumptions are rebuttable by proof to the contrary. The degree of proof required is generally full proof (Vollbeweis): the court must be convinced of the truth of the fact. The standard is not mathematical certainty but a high degree of probability sufficient for practical life, leaving no reasonable doubt. In certain cases, a reduced standard of prima facie evidence (Anscheinsbeweis) applies, allowing inferences from typical courses of events.

Beweisvereitelung (Spoliation of Evidence)

The doctrine of spoliation of evidence (Beweisvereitelung) is recognised in German law as a principle of good faith under Section 242 BGB. Where a party culpably prevents another party from obtaining evidence — by destroying documents, hiding objects, or otherwise frustrating evidentiary access — the court may draw adverse inferences. The specific application in procedural law is governed by Sections 371(3), 427, 441(3), 444 ZPO.

Section 444 ZPO provides that if a party suppresses a document that the other party has offered as evidence, the court may treat the other party’s assertion as proved. This principle extends to other forms of evidence by analogy. The party accused of spoliation must have acted intentionally or negligently; the duty to preserve evidence arises when legal proceedings are foreseeable. The BGH has developed a sophisticated framework for Beweisvereitelung in medical malpractice cases, where failure by a physician to maintain medical records may shift the burden of proof on causation.

Court’s Role in Taking Evidence

The court controls the evidentiary process. The court determines which facts require proof, what evidence is admissible, and the order in which evidence is taken. The court may reject evidence that is irrelevant, inadmissible, or offered for the purpose of delay (Section 286(2) ZPO). The court may also take evidence ex officio under limited circumstances.

Evidence is taken in a formal hearing for the taking of evidence (Beweisaufnahme). The court may designate a single judge to take evidence, or may request judicial assistance from another court. The parties and their attorneys have the right to attend evidentiary hearings and to question witnesses and experts. The court minutes the taking of evidence; the minutes become part of the record and are available on appeal. The judgment must summarise the evidence taken and explain the court’s evaluation.
