Georgia runs two shortcuts, not one threshold
Most states set a single dollar ceiling and call anything under it a "small estate." Georgia instead splits the question in two. A banking affidavit under O.C.G.A. § 7-1-239 releases up to $15,000 held at a single bank, quickly and without any court filing at all. Everything larger, or anything beyond a bank account — including real estate — runs instead through a No Administration Necessary petition under § 53-2-40, which has no dollar cap whatsoever — but only works when the decedent died without a will and every single heir agrees, in a notarized signature, on how to split everything.
The real estate difference most states don't have
Unlike the typical small-estate affidavit elsewhere, which usually excludes real property from the calculation entirely, Georgia's No Administration Necessary petition can transfer title to real estate directly — the probate court then files a certified copy of the order in the deed records of every county where the decedent owned property, within 30 days of granting it.
What actually disqualifies an estate here
Three things end the shortcut and push the estate toward regular probate: a valid will exists (this specific petition is intestate-only), any single heir won't sign the notarized division agreement or later objects, or the estate has debts that creditors haven't consented to or been properly served notice of.
A parallel tool worth knowing: Year's Support
Separately from either small-estate shortcut, a surviving spouse or minor children can file a Petition for Year's Support within 24 months of death, which can set aside estate property for their support ahead of nearly every other claim — sometimes making a full probate case unnecessary for the family's own needs even when other heirs exist.
Filed county by county, statewide
Both shortcuts run through Georgia's 159 county probate courts, so whether the estate is in Fulton County (Atlanta), Cobb County (Marietta), Gwinnett County (Lawrenceville), DeKalb County (Decatur), Chatham County (Savannah), Richmond County (Augusta), Muscogee County (Columbus), or Bibb County (Macon), the underlying statute is identical — only the local filing fee and clerk's paperwork differ.
