An estate means a person's property or net worth. When the person is deceased, their estate goes through probate and is distributed according to the terms of their will. If there is no will, states have rules of intestate succession they use to disperse the estate.
If life insurance proceeds are not left to a person, or the person predeceases the insured person and no other beneficiary is named, then the life insurance proceeds may go into the estate of the deceased. There is it distributed along with the other assets.
