Baroness Tanni Grey-Thompson has been appointed co-chairman of Yorkshire until Lord Patel steps down in March.
Grey-Thompson, who is a non-executive director at Headingley, will then serve as acting county chairman until a replacement is appointed.
Yorkshire said they “will work with a leading international executive search firm to conduct a fair, thorough and robust recruitment process”.
Lord Patel has announced he will step down at the start of the month.
Patel, 62, was appointed in November 2021 after Roger Hutton resigned following the club’s response to the Azeem Rafiq racist scandal.
Former Yorkshire spinner Rafiq said in 2020 that abuse at the club left him on the verge of taking his own life.
Grey-Thompson, who has won 11 Paralympic gold medals, joined the Yorkshire board in May 2022.
“I am grateful to the board, and in particular Baroness Grey-Thompson, for agreeing to be part of a smooth transfer process,” Lord Patel told the club’s website.
“It has been a pleasure to work alongside such an experienced and committed management team, and I know that all are committed to our mission to bring this club back to where it deserves to be, both on and off. ground.”
Yorkshire were relegated to Division Two of the County Championship on the final day of the 2022 season.
