Did the finance company have a court order?
If your finance company did not have a court order to repossess the car, and took it without you consent, then you may have a claim for compensation. We have also acted in cases where consent was obtained under false pretences or threat of violence.
Under section 90 Consumer Credit Act 1974, if you have paid more than one third of the total amount of the goods under the agreement, then your car becomes protected goods. This means that your lender has to issue proceedings at court, to obtain a court order against you, forcing you to return the car.
If they do not do this and took the car anyway you could be entitled to a release from liability under the agreement. This means that you will not owe them any more, and more importantly, you could be entitled to compensation from them equivalent to a refund of all of the sums that you paid under the agreement. This would include any proceeds of sale that they have received from selling the car after they repossessed it.
You will need a copy of your credit agreement and a full statement of account, for us to assess your case.
