You can put off preparing an estate plan. In fact, you can go through life without an estate plan. But why would you want to? If you don't have an estate plan, you may be placing your family members and loved ones in a difficult situation upon your death, or if you become incapacitated.
You can also prepare your own will using computer programs. In the short run, these programs may save you a little bit of money. However, a will must follow a number of legal formalities in order to be valid. If you make a mistake, your loved ones will have to live with the results.
