Legal forms in Sweden: AB, HB, KB and more

Every legal form in Sweden, each with its abbreviation, the kind of entity it is, liability and typical use where they are well established, and the values the Prometiam company object returns.

This guide lists the 26 legal forms the Prometiam dictionary knows for Sweden: what each is called, how it is abbreviated, what kind of entity it is and how it appears in the company object. Use it to read the legal_form of a company registered in Sweden, or to decode a form you meet in a contract or on an invoice. It is a general reference, not legal advice.

Coverage and limits for Sweden: company records only (no officers, no registry-compliance signal); sole traders are never served.

How a legal form appears in the API

Every company object carries four legal-form fields: legal_form (the standard abbreviation, null when the form is not mapped), legal_form_family (the cross-country family, so a private limited company compares across countries), local_legal_form (the register’s own value or code as stored) and local_legal_form_name (the register’s name for it, where it publishes one). Each form below shows the values the API returns for it.
