Dallaglio also has plans to go into coaching or management and will complete the level three stage of the Rugby Football Union's coaching course over the next six months. Part of that training will involve gaining experience at Richmond.
Dallaglio was invited to take a Richmond forwards training session this year and is willing to help out when needed next season.
However, it does not signal a full time involvement with Richmond, who are committed to remaining an amateur outfit.
Dallaglio said: "I did one session for Richmond and would be happy to help Buster White, my old Wasps team-mate, if he needs me next season. I will also be involved off the pitch with Wasps."
