The short answer is – no.
The person/insurer is under no obligation to pay those expenses.
In practical terms though, where the circumstances of the accident are clear, the insurer may agree to pay those costs before settlement. It tends to be uncommon.
However, you can certainly claim any expenses incurred because of your injuries through the claim itself. It forms part of your claim costs – which will be recoverable in a lump sum.
And of course we will be working hard to move your matter forward as quickly as possible and ease any financial burden you’re suffering as a result of your injuries.
