Wakefield Trinity Wildcats chairman Michael Carter says the club could be forced to leave their Belle Vue home after serving notice to the administrators of the ground's lease.
The Super League side have played at the ground, which is owned by Bank of Ireland, since 1895.
As it stands, their lease will terminate at the end of December.
"The current lease and cost of repairs is crippling the club," Carter told BBC Radio Leeds.
"We made a reasonable offer of what we could afford over the next 18 months but never got a reply and Wednesday was the deadline that we had to give six months' notice.
"The ball is in their court now and it may be that we get no response and they are happy to take back ownership of the ground. I can't talk on their behalf."
The Wildcats were hoping to move to a purpose-built stadium for the start of the 2015 season but work has never started on the project.
Carter says he has spoken to several different clubs about possible groundshares for 2016.
He added: "We've already looked at alternatives because it's no good us saying we have six months to get something sorted - realistically you need to have something in place well before then.
"We've had a number of discussions with other grounds at this time, which will remain confidential."
