Cal. Prob. Code § 19041
The Legislature finds and declares that to be most effective, notice to creditors should be published in compliance with the procedures specified in Section 19040. However, the Legislature recognizes the possibility that in unusual cases due to confusion over jurisdictional boundaries or oversights the notice may inadvertently be published in a newspaper which does not meet these requirements. 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 19040 shall be sufficient to provide notice to creditors and establish jurisdiction if the court expressly finds that the notice was published in a newspaper of general circulation published within the city, county, or city and county and widely circulated within a true cross section of the community in which the deceased settlor resided or wherein the principal place of administration of the trust was located or the property was located in substantial compliance with Section 19040.
