An estate plan is a set of legal documents which outline how your assets will be managed if you become incapacitated (i.e., unable to manage your own assets after an illness or injury) or pass away. Most estate plans consist of a will, or a trust, plus a durable power of attorney for finances, a healthcare power of attorney, final wishes and a guardianship designation if you have minor children. Other aspects of an estate plan may also include things like making your wishes known about your funeral and adding a life insurance policy.
