Hi Adelle,
Is there a police report/statement made at the scene, or after, the accident? If so, you may request a copy and this should be able to better support your claims.
Unfortunately, there is no easy way to resolve disputed claims for damages where you believe the damages are exorbitant or incorrect. You may refuse to pay the full amount or any amount of the claim. In this case, the other party may seek to recover the damages in court (most likely the
Civil Claims list of the Victorian Civil and Administrative Tribunal "VCAT"). If this happens, I would recommend speaking with a legal representative and/or
Legal Aid.
To avoid court, it may be best to try and negotiate a settlement agreement beforehand. Try speaking with the other party. If you need assistance in dispute resolution, you can try the
Dispute Settlement Centre of Victoria. They are a free, voluntary service that offers alternative dispute resolution guidance.
Keep all correspondences related to this dispute in writing, or subsequently recorded in writing, and as much tangible evidence to support your claim as possible. Have records that are as detailed as possible (dates, parties, times, contents).
