Liability insurance can protect you in the event of serious injury, property damage or other economic liability. Thus, understanding liability insurance is an important piece of your personal financial plan.

One of the most common types of liability insurance is bodily injury and property damage for your auto coverage. It provides payment to others when you are the driver at fault in an accident. Arizona has minimum levels of coverage of $15,000 bodily-injury liability per person, $30,000 per incident (two or more people) and $10,000 for property damage ($15k/$30k/$10k). If someone has a $50,000 medical claim and you only have the minimum $15,000 in bodily injury coverage, they may pursue you for the remaining costs. More typical levels of coverage are $100k/$300k/$100k.

Another common type of liability protection is a vital component of homeowner’s insurance. Coverage typically starts at $100,000; however, to protect your family’s assets, $300,000 or more is advisable. If a guest or contractor slips and falls on your property, medical bills and lost wages can quickly add up to more than $100,000. Do you have a dog, pool or trampoline? Claims from these risks are common for pain and suffering, as well as for medical bills.

An umbrella liability policy is less common, though strongly recommended. Also known as a personal liability policy, it complements your auto and homeowner’s insurance by extending liability coverage where the underlying policies end. A car accident resulting in severe injuries can quickly exceed $500,000 in medical bills, property damage and lost wages, not to mention claims for pain and suffering. Any amount not covered by your auto policy could cause an action to be brought against you and your family for your personal assets (bank accounts, cars, home equity, wages). With a $1 million umbrella liability policy, you would have more sufficient coverage. In addition, the insurance company would pay for an attorney to represent you and negotiate with the other party.

More generous umbrella policies may also cover claims such as false arrest, libel or slander (such as a negative online review). Premiums for umbrella policies typically range from $250 to $500 per year for an additional $500,000 in liability protection.
