What is a Mirror Will?
A Mirror Will is actually two Wills, usually created by partners or married couples. The two Wills typically name each partner as the main beneficiary of the other partner’s estate. There may be other specific gifts within the Will, such as gifts to charities, but the two Wills look identical to each other, except that typically, the name of the main beneficiary is the partner of each testator.
Person A leaves everything to Person B. Person B leaves everything to Person A.
Then for the two Wills to be true mirror Wills, each Will describes an identical alternate plan in the event that both partners are involved in a common accident. Often this is that the entire estate is then distributed to the children.
