Can I ask a private parking company to prove I was driving in Northern Ireland?

Private parking liability in Northern Ireland is centred on the driver. The Protection of Freedoms Act keeper-liability mechanism used in England and Wales does not apply, so receipt of a notice as registered keeper is not the same as proof that you personally parked the vehicle.

State the position accurately and in writing. Keep a copy of your challenge and do not invent another driver. If you have legitimate evidence that you were elsewhere, it can be included, but the core point is that the claimant must establish its case against the person it pursues.

The operator may still ask for driver details, continue correspondence or issue a Small Claims Court claim. If court papers arrive, respond through the court process rather than assuming the earlier keeper argument means no response is needed.
