The four started action against the site owners to try and get money back
Four families who bought park homes without planning permission and have now been told to leave are taking legal action against the site owners.
The properties at a site near Highley, Shropshire, are not freehold so the families pay a fee to the owners of the land.
The site owners were told by Bridgnorth District Council they had to return the land to its previous green field state.
But the land owners said the families had been offered a similar plot.
The Loveridge family, who own the site, added they were unable to comment further until legal matters were resolved.
Although a retrospective application was submitted, the council refused it on the basis it would set a dangerous precedent.
The council said the planning enforcement notice it served requiring the homes to be removed had now expired.
And the authority said it would now collect evidence for potential prosecution against the land owner.
The families have started legal action against the Loveridge family to try and get their money back.
'Don't have funds'
One of the men taking action, John Brough, said the families were supposed to have left by 19 April, but were still in their properties.
Annie Brough added: "If they (the owners) don't buy the home back off us, we can't move.
"We don't have the funds to be able to move forward and put this all behind us basically."
She said if the case was not won, she would be homeless and does not have the funds to buy anything else.
