Hi thanks for all your replies.
The insurance company name is Markerstudy Insurance services Limited. They already paid my father last year when he submitted the claim so his car is fixed and now the insurance is trying to get their money back.
I attach 2 letters that they have sent my father. The 1st letter they sent is saying that there was no valid MOT on the car so the policy conditions have been breached and they are looking for reimbursement.
Following that letter, my Mother then phoned the insurance which is when the insurance guy scared her that she could be liable to pay for the costs of the motorcyclist and she agreed to reimburse the insurance company the £3k for the repairs to my fathers car.
The 2nd letter confirms the telephone conversation. Unfortunately they dont have a copy of their insurance policy.
At the time of the accident my Fathers car was roadworthy and in no way did the condition of the car contribute to the accident. The sun was low and he just didnt see the motor cyclist when he pulled out.
Once he realised he had no MOT, he took it in and it passed with no advisories.
I am going to ask my parents to email the insurance company stating that the car was roadworthy at the time and we will not be reimbursing them.
Is this the correct approach?
