Incorporation
Osborne's "Concise Law Dictionary" defines incorporation as a "merging together to form a single whole; conferring legal personality upon an association of individuals, or the holder of a certain office, pursuant to Royal Charter or Act of Parliament".
For purposes of company law it denotes the legal process by which a group of people are enabled to carry on a business in such a way that the business is legally regarded as "a legal entity" that is altogether separate from the members of the group, individually and collectively. This mode of carrying on a business is resorted to because it has certain legal advantages. The business so incorporated is usually called "a company".
