Bournemouth have revealed plans to leave Dean Court.
The club's current home at the 11,450-capacity Vitality Stadium is leased from property company Structadene.
Chief executive Neill Blake said the club would "not be held to ransom" over a price to purchase the ground or "develop a ground they do not own".
Bournemouth, in their second top-flight season, hope to have a new stadium built in time for the 2020-21 season.
"We feel we have no other option but to find a new site," Blake added. "We are working closely with Bournemouth Borough Council to identify a suitable location."
The Cherries have played at their current ground, formerly known as Dean Court, since 1910, but it was sold to Structadene in 2005 in a sale-and-leaseback deal.
