Estate planning is the process of anticipating and arranging for the management and disposal of a person's estate during the person's life in preparation for a person's future incapacity or death. The planning includes the bequest of assets to heirs, loved ones, and/or charity, and may include minimizing gift, estate, and generation-skipping transfer taxes. Estate planning includes planning for incapacity, reducing or eliminating uncertainties over the administration of a probate, and maximizing the value of the estate by reducing taxes and other expenses. The ultimate goal of estate planning can only be determined by the specific goals of the estate owner, and may be as simple or complex as the owner's wishes and needs directs. Guardians are often designated for minor children and beneficiaries with incapacity.

A will and testament is a legal document that expresses a person's (testator) wishes as to how their property (estate) is to be distributed after their death and as to which person (executor) is to manage the property until its final distribution. For the distribution (devolution) of property not determined by a will, see inheritance and intestacy.
