Putting the estate plan into operation upon a person’s death is what is involved in the probate and trust administration process. When you die, you leave behind your estate. Your estate consists of your assets, all of your money, real estate, and worldly belongings. Your estate also includes your debts, expenses, and unpaid taxes. After you die, somebody must take charge of your estate and settle your affairs. This person will take your estate through probate, a court supervised process that winds up you financial affairs after your death.
