The form book ensures successful case handling in the area of social security law. Drawing from their judicial practice, the authors develop practical aids based on realistic life situations, taking into account the current case law of the Federal Social Court. Recurring procedural situations in administrative and litigation processes, as well as the legal remedy procedures in the first and second instances, are addressed, while the special section deals with substantive law in its various facets. The second edition takes into account the legal simplification reform and the current higher court rulings. Important new decisions from the Federal Social Court regarding the exclusion of foreigners and EU citizens from benefits, the clarity of cancellation and reimbursement notices, integration agreements, and integration benefits have been translated into concrete practical aids.
