a receipt is not proof of damages. It is proof the bill was paid. All that is required for proof of damages is an entity that would provide the repair that is acceptable to the court says the damages are $XXX.xx.
So, in this case, the doctors billing is adequate proof of the amount of damages, maybe.
Now, since there are situations where doctors billings are paid at less than full billed amount due to some contractual relationship (PPO insurance is one such possibility), the actual payment record could be required to prove the damages.
so, what is the situation so you can get some specific answers?
