Over 64% of parking fine challenges in Mole Valley were successful last year.
The figures cover initial disputes relating to on-street parking tickets between January and October 2016.
Success rates vary hugely across the 98 authorities asked, with Basingstoke on 95% at the top and Runnymede at the bottom with 9.2%.
Guy Anker from MoneySavingExpert dot com, said those who have a challenge rejected, should appeal to the independent Traffic Penalty Tribunal, as generally half of all decisions are then overturned.
