Legal form suffix (Rechtsformzusatz)
Also: Rechtsformzusatz, company suffix
In short
The legal form suffix is the part of the name that shows the legal form, for example "GmbH", "UG (haftungsbeschränkt)", "e.K.", "OHG", "KG" or "eGbR". It is mandatory and belongs on business letters, invoices and in the legal notice.
Legal form suffix (Rechtsformzusatz) explained
Which suffixes apply is governed by Sec. 19 HGB for sole traders, the OHG and KG, Sec. 4 GmbHG for the GmbH, Sec. 5a (1) GmbHG for the UG and Sec. 707a (2) BGB for the eGbR. For the UG, only two versions are permitted: "Unternehmergesellschaft (haftungsbeschränkt)" and "UG (haftungsbeschränkt)". If no natural person is liable in an OHG or KG, the company name must indicate this, for example "GmbH & Co. KG" (Sec. 19 (2) HGB). Business letters must also show the registered office, register court and register number (Sec. 35a GmbHG, Sec. 37a HGB), and the legal notice of legal entities must show the legal form (Sec. 5 (1) no. 1 DDG). If the suffix is missing, the person acting can be personally liable.
