It truly depends on the severity of the injury and complexity of the case at hand. Often times, such as an automobile accident, claims may settle prior to filing a lawsuit and only take a month to several months to settle. However, for more complex cases such as medical malpractice and product liability claims, extensive investigation and document gathering must be done prior to filing suit and may take several months until the claim is even ready to be filed. Once filed, discovery in complex cases can easily last a year or two. Usually cases are mediated within one year of filing suit. If your personal injury requires a trial, it is not unusual for the it to take up to three years or longer until it is fully resolved.
