Multi-Discipline Practice and Multi-Discipline Partnership


Lawyers and licensed paralegals may form a Multi-Discipline Practice with professionals who practise a profession, trade or occupation that supports or supplements their practice of law or provision of legal service (e.g., accountants, tax consultants, trademark and patent agents, etc.).

When a licensee and a professional enter into a formal partnership agreement, it is considered to be a Multi-Discipline Partnership, which must be approved by the Law Society by application. The licensee must comply with Part III of By-Law 7.

Licensees are responsible for the actions of professional partners and must maintain professional liability insurance for all professional partners.

Who can apply

All licensees who are entitled to practice law or provide legal service with the Law Society and who wish to form a partnership with a professional may apply.

Initial Application Requirements

  • Submit completed original Application for Multi-Discipline Partnership (MDP)
  • Submit copies of pertinent partnership agreements
  • Submit non-refundable administrative fee (includes one professional partner)
  • Submit non-refundable fee for each additional professional partner

Ongoing Requirements and Non-compliance

Once the Multi-Discipline Partnership is approved, the licensee(s) who formed the Multi-Discipline Partnership are required to submit the Report on Multi-Discipline Partnership by January 31st each year for the previous year, including any changes in participants, agreements and/or other information.

Failure to submit the Report on Multi-Discipline Partnership annually could result in administrative suspension.
