Directive 2005/56/EC provides a harmonised framework for cross‑border mergers of limited liability companies within the European Union. It applies where at least two merging companies are governed by the laws of different Member States and prescribes core steps: common draft terms, publication, independent expert report (with option for a single joint report), management report, approval by each company’s general meeting, and issuance of a pre‑merger certificate by the competent national authority. The law of the company resulting from the merger determines the date on which the merger takes effect and national registries must record completion.

The Directive protects members, creditors and employees by requiring minority safeguards, creditor remedies, automatic transfer of employment contracts and rules on employee participation modelled on the SE regime and Directive 2001/86/EC, including negotiation procedures and thresholds. It allows simplified formalities in cases of complete or near‑complete ownership, preserves national public‑interest controls, bars post‑effect nullification of a valid merger, and required Member States to transpose the Directive by 15 December 2007 with a Commission review after five years.
