The Legislature finds and declares that, to be most effective, notice of hearing should be published in compliance with Section 8121. However, the Legislature recognizes the possibility that in unusual cases due to confusion over jurisdictional boundaries or oversight such notice may inadvertently be published in a newspaper that does not satisfy Section 8121. Therefore, to prevent a minor error in publication from invalidating what would otherwise be a proper proceeding, the Legislature further finds and declares that notice published in a good faith attempt to comply with Section 8121 is sufficient to provide notice of hearing and to establish jurisdiction if the court expressly finds that the notice was published in a newspaper of general circulation published within the county and widely circulated within a true cross-section of the area of the county in which the decedent resided or the property was located in substantial compliance with Section 8121.
