You need a will. Make a simple will and attach a list that says what property you have and who you want to get it. You can update your list as your personal property changes, even if you do not change your will.
Things like jewelry, family pictures, personal papers, tools, or furniture can have sentimental or other value, but don’t have documents to show who owns them.
If you leave these items out of your will, they might go to a person you do not want to have them, or your heirs may not agree on who should get them. Sometimes sentimental property causes the biggest disagreements among family members.
You don’t need a will if you give your property away before you die.
