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.
Technically, probate doesn’t take very long. Just long enough for a Judge to review the Will and validate it.
What takes the longest is the administration of the estate. That is paying the bills and distributing the property. In Arkansas, you can expect at least 7 months to finish. 6 months of that is the time for any outstanding creditors to make claims.
