Alex, thanks for response. The amount owed is $7,500. The vehicle is worth a little more than that. There job card does not mention any right to sell - we will get this changed (but that's a different issue). There is no statutory right just common law.
You have a legal lien on the vehicle for the parts used.
Together you have a common law right
You need to write to the owner and give 28 days to cough up or say you are going to sell.
Make sure this is hand delivered or signed for so you have a record.
If they do not get back to you or payment by installments then you can sell the vehicle
But you needed to have given adequate notice
Can I clarify anything for you about this today please?
Many thanks Alex, that's fine
