Filing a Lawsuit via Fax by a Lawyer – Check Legal Validity

Form Specifications for Lawsuits since January 1, 2022

Published on February 16, 2026

Effective January 1, 2022, specific requirements apply to attorneys in financial court proceedings regarding the transmission of decisive documents. This particularly includes the filing of lawsuits. The background to this is the mandatory use of electronic legal communication, which has significantly replaced the previously common transmission methods – such as fax – for professional filers in essential areas.

Subject of the Proceedings and Initial Situation

The decision of the Financial Court of Düsseldorf from January 19, 2023 (Case No. 7 K 504/22 K) was based on a lawsuit that was submitted by a lawyer via fax after the deadline of January 1, 2022. The decisive issue was not the substantive dispute, but the formal validity of the lawsuit filing.

The court determined that since January 1, 2022, lawyers are required to submit decisive procedural documents initiating proceedings in electronic form. A transmission by fax generally does not meet these requirements. Against this background, the Financial Court denied the effectiveness of the lawsuit filing in the chosen form.

Distinction between Electronic Form and Alternative Communication Methods

The decision illustrates the strict separation between electronic transmission in the designated technical format and methods that only allow for telegraphic transmission. According to the legal system, fax cannot simply replace the electronic submission intended for lawyers.

Significance of Formal Requirements in Financial Court Proceedings

The decision shows that the form requirements are not treated as mere procedural rules, but can have direct implications on the admissibility of a lawsuit. If the lawsuit is not submitted in the prescribed form, it may be considered not effectively filed.
