Frequently asked questions

How do I check if a lawyer is licensed in Minnesota?

Search their name or bar number in the lookup above to find their record in the Minnesota Judicial Branch — Lawyer Registration Office (MARS public bulk roster). This directory confirms that an attorney is on the Minnesota roster; it does not publish current license status, so confirm standing directly with the official source.

How many attorneys are registered in Minnesota?

53,206 attorneys are on the Minnesota Judicial Branch — Lawyer Registration Office (MARS public bulk roster) roster.
