Advise Patricia as to whether she can get her car back

Patricia was the owner of a BMW car. As Patricia decided to live abroad for a long time, she entrusted her friend, Lucy, to market and sell the car at a price between £26,000-£30,000. Patricia and Lucy agreed when Lucy found a buyer, the final decision of sale should be made by Patricia. In return, Lucy was paid £1,000 for her time and effort.

In order to give potential buyers an opportunity to test drive the car and convince them that Lucy was not a fraudster, Patricia gave Lucy the keys to the car. Patricia also signed a letter certifying that the car had been sold to Lucy. However, Patricia agreed with Lucy privately that this was not a true sale. The only purpose of providing this letter was to facilitate the negotiation between Lucy and buyers. Later, Andrew approached Lucy and said he was interested in the car. The car was priced at £30,000 and Andrew was happy with that price. Lucy believed that this was a good deal, so she sold the car to Andrew. In their agreement, Lucy allowed him to drive the car away after receiving a £30,000 cheque. However, to reduce risk, they inserted a retention of title clause in the contract which provided that, without receiving payment from Andrew’s bank, he would not have the title of the car.

Andrew forgot that his bank balance was insufficient in his account, so the cheque was dishonoured by his bank after he had the possession of the car. Later, Andrew sold the car to his friend Seven for £5,000. When Seven asked for the car documents, Andrew replied that he could not provide them. After a few days, Patricia knew that her car was sold by Lucy without seeking her approval. She would like to claim the car back from Seven.
