Absolutely not! Under no circumstances should you contact the insurance company once you have retained an attorney. If you contact the other person's insurance company for any reason, you could ruin your entire case with one question or statement.
If you have health insurance, medical payments insurance, automobile uninsurance or underinsurance coverage, there may be occasions when it is appropriate for you to contact your own company. However, you should always ask your lawyer whether or not such contact is appropriate. Never contact an insurance company without first obtaining approval from your attorney.
