In common law jurisdictions, probate is the judicial process whereby a will is "proved" in a court of law and accepted as a valid public document that is the true last testament of the deceased, or whereby the estate is settled according to the laws of intestacy in the state of residence of the deceased at time of death in the absence of a legal will.
An attorney meets with client for estate planning.
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.
