Advokatfirmaet Advisio AS is a Norway-based boutique law firm specialising in matters linked to work, health, family and social security. The firm advises both private individuals and organisations and is recognised for concentrating its practice on complex welfare-law and family-law problems rather than broad general practice.

The firm was founded and is led by experienced practitioners with deep subject-matter knowledge; the founder, Olav Lægreid, has prior service in a judicial capacity at the Social Security Court and maintains academic affiliations that reinforce the firm’s technical competence in welfare and health-related legal matters.

Advisio positions itself as a problem-solving practice that combines technical legal analysis with pragmatic client service, offering initial case assessments and tailored strategies for negotiation, administrative appeals and litigation. The firm has an established role in specialist welfare and insurance disputes and works with patient and disability organisations on systemic issues while also representing individual clients in high-stakes proceedings.
