You should certainly consult with a lawyer before your car accident insurance interview, and it is in your best interests to do so. However, be aware that if you have already made a statement, it is difficult to change it later, even if it turns out that you said something that can hurt your case. If you change your statement, the inconsistency can be used against you and this will typically weaken your case.
Getting Legal Help for Your Car Accident Insurance Interview
Often, even the most straightforward car accident case creates a number of legal issues, often beginning with the insurance interview. For example, the other party's insurance company may try to dispute fault, or they may claim that you were responsible for the car accident and not their insured client. If this was really true and you were responsible for the accident, then they wouldn't have to pay. Unless the evidence is clear, this tactic may actually be tried in order to avoid paying out a claim. Even if they accept responsibility, there are still legal issues to deal with, like determining the dollar amount for your damages. Their goal is, of course, the opposite of yours: you want to get compensated as much as possible, and they want to pay out as little as possible.
This means any information you share with them could potentially be used against you. Even something as simple as saying you are feeling great or much better could be used to diminish the amount of pain and suffering damages that you are awarded on the basis of the accident. As such, before you say anything else to them, you need to consult with a lawyer to determine how to best proceed to get the most recovery possible.
Simply tell your lawyer everything you said in the original statement you made, and your lawyer can help you to do damage control if you said something wrong. S/he can also help make sure you are able to go into any future conversations fully informed.
