Legal form (Rechtsform)
Also: Rechtsform, Gesellschaftsform, Unternehmensform, business structure, type of company
In short
The legal form is the legal framework of a business and determines liability, capital, formation effort, say in decisions and taxes. Common legal forms in Germany include the sole proprietorship, GbR, OHG, KG, GmbH, UG and AG.
Legal form (Rechtsform) explained
The first question when choosing is usually liability: sole proprietors and partners in a GbR and OHG are personally liable without limit, while in a GmbH and UG only the company's assets are liable from registration. The second question is capital: sole proprietorships and partnerships need none, the UG manages with little, and the GmbH needs €25,000. Then there are the notary, register, bookkeeping and taxes. The legal form can be changed later, for example from a sole proprietorship to a GmbH, or by a change of legal form under the Transformation Act (Sec. 190 UmwG).
