It is one of the most important documents included in an estate plan. A will is filed with the probate court and does not take effect until after death. It is a document that outlines how you want your affairs to be handled and how your assets are to be distributed upon your death. You can also appoint guardians for your minor children in the event you die before they reach the age of 18. If you die without a will or with a will without guardians, the probate court will determine who becomes the guardian of your children. If a person dies without a will, s/he is deemed to have died “intestate” and state laws will determine how and to whom the person’s assets will be distributed.
