Alliott Group is one of 23 members of the European Group of International Accounting Networks & Associations (EGIAN) [3]

Logo of Alliott Peirson International, the forerunner to Alliott Group

The original founding firms already had working relationships and mutual clients but established a formal association in Alliott Peirson International, Alliott Group’s forerunner, in 1979.[5] The association’s aim was to meet the needs more efficiently of those clients that needed assistance when expanding into or facing challenges in different jurisdictions around the world. As client demand for services in new locations grew, member firms were (and continue to be) appointed in key commercial cities across the world.

Multidisciplinary expansion

According to Inside Public Accounting, "Alliott Group was one of the first international groups to adopt an interdisciplinary approach." [6] The association opened its membership to law firms in 2004, and as of June 2017, 31 law firms are members. As a result, Alliott Group may be listed as an international law firm network [7] or as one of a small number of Multidisciplinary professional services networks.
