Legal Associate

Why become a Legal Associate?

Legal Associate membership is awarded in recognition of the applicant's achievement and demonstrable competence in planning law.  The status of Legal Associate of the RTPI, denoted by the post-nominals LARTPI, is an important milestone and a mark of professional recognition. It shows clients and other professionals that the holder has both experience of and expertise in planning law.

The RTPI assesses legal practitioners' expertise in planning law but does not regulate them: this responsibility remains with the relevant professional body (e.g. for solicitors in England and Wales, this is the Solicitors Regulation Authority).


Legal Associates have access to RTPI member benefits and services.

Successful candidates are able to use the post-nominals LARTPI to denote their status.

How to become a Legal Associate


To be eligible to become a Legal Associate candidates must:

  • be a qualified legal practitioner (solicitor, advocate or barrister, or Chartered Legal Executive);
  • be able to demonstrate that they have sufficient experience in planning law, as opposed to other types of law, to apply for this specialist membership class.

Full details of the eligibility criteria are in the guidance.
