Here are 10 "life" situations that require changes in your insurance coverage, starting with #1: Getting Married or Divorced, and #2: Switching Jobs.
#1: Marriage or Divorce
When you get married it makes sense to start combining insurance policies. Combining two car insurance policies into one policy could save you money. As you and your partner move in together and start combining property you need to revisit your homeowners insurance or renters insurance policy as well. This is also a good time to think about term life insurance -- you want to make sure that your partner is taken care of should a tragedy occur.
Getting a divorce necessitates setting up separate policies, since you are presumably no longer sharing cars and/or homes. Also, you'll need to update your term life insurance policy's beneficiaries.
#2: Switching Jobs
If you have just landed a new job your driving situation may have changed. If your new job is farther from home, your annual mileage will be higher. Perhaps you will be telecommuting or using public transit and so you'll drive considerably less. Additionally, if you've been receiving term life insurance benefits from your previous employer, you need to make sure you can continue that coverage with your new employer or go out and shop for life insurance on your own.
