Definition: Ad and D Insurance refers to a type of life insurance that pays out cash in the event of your death or disability. It is also known as "daylife" or "life after day." In other words, an ad and d insurance policy provides financial support for the family when you are no longer able to work or make contributions. The term 'ad and d' comes from the French word "ad" which means "at," and "d" which means "and." It is a way of referring to events that occur after death. The term 'ad' can refer to anything that happens to you while alive, such as a family member's passing or your own demise. The term 'd' in the ad-and-d insurance policy refers to the fact that it pays out money when someone dies or is disabled. This means that if your loved one passes away or becomes disabled, your life insurance company will pay out the amount of the premium you paid for the policy, minus any penalties and fees. Overall, 'ad and d'insurance policies are designed to provide financial support to those who depend on their loved ones in times of need. They are often used to help people who may have lost a job or income due to illness or disability, or to help elderly families deal with the cost of caring for members of their family.
