It varies. Each motorcycle claim is different. The first step is typically negotiating with an insurance company for a settlement amount. If the insurance company agrees with the number you’re demanding, then the case could be resolved in as little as six months or even less.
Having an attorney from the beginning can help move the process along as well.
If the insurance company denies your claim or offers you an inadequate settlement amount, then you will have to file a lawsuit. Going this route may be the only way to get the compensation you deserve, but it could take years to reach a verdict.
