You do — whether your estate is large or small. Either way, you should designate someone to manage your assets and make health care and personal care decisions for you if you ever become unable to do so for yourself. For many, such “life planning” is the most important aspect of an estate plan.
If your estate is small, your plan may simply focus on who will receive your assets after your death, and who should manage your estate, pay your last debts and handle the distribution of your assets. If your estate is large, your lawyer will also discuss various ways of preserving your assets for your beneficiaries and of reducing or postponing the amount of taxes which otherwise might be payable after your death.
