Here are 16 things you can do to prepare.1, make a list of all items you own that are worth $100 or more. That includes home, jewelry, computers, cars and so on. 2, add your non-physical assets, like brokerage accounts, 401ks and IRAs, insurance policies, and anything else that’s on paper and valuable. 3, list all debts and credit cards. Run a free credit report to check for inaccuracies. 4, list every organization you belong to. Think AAA, AARP, college alumni, the American Legion, charities. 5, send dated, signed copies of your assets list to your estate administrator. 6, review your IRA, 401k and other retirement accounts, and make sure your beneficiary designations are current. 7, update your life insurance and annuity policies with current beneficiaries. 8, assign transfer-on-death designations for your bank, CD and brokerage accounts. 9, select a responsible estate administrator. 10, create a will. 11, Review and update documents in your will after any life-changing event, like a divorce. 12, send copies of your will to your estate administrator after it’s been finalized, signed, witnessed and notarized. 13, visit a financial planner or estate attorney to make sure you have full investment and insurance plans. 14, initiate important estate plan documents, like trusts and power of attorney, and make sure any concerned individuals have copies. 15, simplify your life by consolidating retirement accounts. 16, take advantage of college funding accounts, like a 529 plan, for your grandkids.
