We know you and your spouse love each other—but as individual adults, each of you needs your own will. Sharing a will isn’t a good idea. Using one will for both spouses used to be pretty common through a form known as a joint will.
But the problem with a joint will is that it’s impossible for the surviving spouse to change the will after one spouse dies. To avoid this, you and your spouse need mirror wills—they’re almost exact duplicates of each other and give you the flexibility for future estate planning if one of you dies.
