Motor third party liability insurance is a legal requirement as per the Motor Vehicle Act, 1988. If you own or drive a motor vehicle, you will need it to stay on road. The coverage protects you from the liabilities resulting from lawsuits, accidents, financial loss or damage to property. Most of the insurance providers offer it as part of the primary car insurance. If you go for standalone third party liability insurance, your insurer may even add a comprehensive car insurance policy to it.
