In cases where a creditor first sends the debtor a warning letter or initiates the Order for Payment Procedure, no evidence needs to be presented.
If, however, the creditor chooses to initiate court proceedings against the debtor, then the creditor needs to provide evidential proof, e.g., of a written contract, services or goods provided, invoice(s) issued, delivery notes et al.
If the debtor, in their defense, cites the absence of a contract or order placed, non-receipt of goods or services, or damaged or faulty goods received, the creditor must present all evidence to support their claim.
Evidence admitted by the courts includes documents, witness testimony, on-the-spot inspections (physical and testimonial evidence), as well as statements given by parties or expert witnesses.
In debt collection cases, the German courts typically prefer documentary evidence over witness testimony. Careful and thorough filing of all documentation relevant to a business relationship is, therefore, essential for success in any eventual debt collection case.
Both the creditor and the opposing party may submit evidence to the Court at any point, from the filing of the case, up to the court hearing itself.
In this way, the creditor may issue the writ while stating that all evidence will be submitted in due course. This provides the creditor with valuable time to complete their discovery.
Claims not supported by adequate evidence will not succeed.
