+Eversheds Sutherland will provide all aspects of legal advice for event organisers as part of the agreement.
Tournament chief executive Jon Dutton said: “To secure the first official partner more than four years out from the tournament is great news, particularly given that Eversheds Sutherland are a global brand with 66 offices across 32 countries.
This year’s World Cup takes place from 26th October to 2nd December and will be co-hosted by Australia, New Zealand and Papua New Guinea. Australia is the defending champion.
“Eversheds Sutherland will bring strong legal acumen to help support the company’s development and their proactive approach has ensured they are the first of what I am sure will be many commercial partnerships that we will announce in the build-up to the tournament.”
