If you can offer your local council a realistic deal that you can stand by, I am sure they will compromise, you will be asked not only to pay arrears but your present yearly rates,
local councils are really stretched for money at the moment owing to so many shop closures.
The outcome of a court appearance can sometimes depends on what the judge had for breakfast but my guess is that it will only buy you more time, you will still owe what's owed, not to mention the stress!. If at all offer your local council a sincere effort to resolve, as small as it maybe, remembering that they too would wish to avoid litigation, hope this helps
