Key facts: Iowa intestate succession is governed by Iowa Code Chapter 633; small estates valued at $50,000 or less qualify for affidavit-based collection after a 30-day waiting period; surviving spouses receive priority inheritance with the first $50,000 plus one-half of the remainder when children also survive; order of succession proceeds through spouse, children, parents, siblings, and more distant relatives when applicable; estates with no heirs ultimately escheat to the State of Iowa.
