Hearts have become the UK's largest fan-owned club after Ann Budge's majority shareholding was signed over to the Foundation of Hearts.
Around 8,000 supporters make monthly pledges to the group with them officially taking ownership on Monday.
Budge, who will stay as chair for at least "two years", says the importance of being fan owned but not fan run is crucial for the club's future.
She bought Hearts out of administration for £2.5m in 2014.
"It's been seven hard years and many people have said you couldn't do it, and we have proved it can be done.
"Everything has worked, almost to a dream. The club is financially secure, more so than its been for any time in the last seven years. The club are sitting top of the league and everyone has a right to be happy."
