Key facts: California Probate Code § 13100 governs small estate transfers; the eligibility threshold is $184,500 in total gross estate value; a mandatory 40-day waiting period applies from the date of death before petition filing; an Inventory and Appraisal with certified appraisal is required; all heirs and beneficiaries must receive notice of the petition; formal probate may be required if the estate exceeds the statutory threshold; and the small estate order authorizes but does not guarantee clean title for subsequent transactions.
