four-month tolling period must be added to the tort and contract statutes of limitations per AS 13.16.455. Even so, Mary's monthly support and home improvement claims are again barred by the operation of non-probate statutes of limitations: the home improvement claim was barred as of March 9, 2005 (last accrual date being Marjorie's death on November 9, 2001; I add three years per AS 09.10.053 and four months per AS 13.16.455), and the monthly support claim was barred as of March 9, 2004 (same date arising; I add two years per AS 09.10.070 and four months per AS 13.16.455). Thus, both claims were barred against Marjorie's and Michael's estates well before they were presented on November 4, 2008.
The superior court therefore did not err in holding that Mary's Claims arising before death, "if not barred earlier by other statutes of limitations, are barred against the estate ... unless presented" either "(1) within four months after the date of the first publication of notice to creditors if notice is given in compliance with AS 13.16.450," or "(2) within three years after the decedent's death, if notice to creditors has not been published."

Alaska Statute 13.16.450, the notice provision, states in full:
Unless notice has already been given under this section, a personal representative upon appointment shall publish a notice once a week for three successive weeks in a newspaper of general circulation in the judicial district announcing the appointment and address and notifying creditors of the estate to present their claims within four months after the first publication
