Neil Golding has been appointed as Saracens' new non-executive chairman following Nigel Wray's retirement last week.
Long-term chairman Wray stepped away from the club with immediate effect, two months after Sarries were docked 35 Premiership points and fined £5.36million for breaching salary cap regulations.
A statement on Thursday said the "immediate priority" for Golding, a Freshfields Bruckhaus Deringer lawyer, was to "oversee new governance measures including steps to ensure regulatory compliance".
Sarries have the joint-best record in the Premiership this term but sit bottom of the table on minus seven points as a result of their punishment.
Golding said: "It is an honour to be appointed chairman of Saracens.
"The success of this great club is rooted in its commitment to the development of talent through its coaches and academy system, player welfare and making a positive impact within its community to create lasting memories.
"I am excited to help build on this wonderful legacy. I also recognise that I am joining the club at a time of significant change.
"We, as a board, are strongly committed to introducing new robust processes and working together with other PRL stakeholders in the best interests of Saracens and English rugby."
