(b) If real property as described in subdivision (a) is discovered prior to tax sale by delivery to the tax collector of a certified death certificate, the public administrator of the county where the decedent resided at the time of death, and in the county in which the property is situated, if different, shall be notified of the decedent’s property that is subject to loss, injury, waste or misappropriation under Section 7600 of the Probate Code. The public administrator of the county where the decedent resided at the time of death shall take possession or control of the property under Section 7601 of Probate Code and conduct a probate investigation as authorized under Sections 7602 and 7603 of the Probate Code. Following the probate investigation, the public administrator shall do one of the following:

1. (1) If a person with a higher priority cannot be found to assume responsibility for the estate, the public administrator of the county where the decedent resided at the time of death shall immediately commence probate proceedings with respect to the property, and the tax sale may not be made. The probate proceedings may be summary proceedings, as authorized by Section 7660 of the Probate Code, or formal proceedings as authorized by Letters of Administration from the Superior Court under Section 7620 of the Probate Code. A tax sale may not be made until the probate process is completed.
2. (2) If a person with a higher priority cannot be found to assume responsibility for the estate, and the value of the estate will not cover the taxes, the secured liens, and the cost of probate, the public administrator of the county where the decedent resided at the time of death, as authorized by Section 7603 of Probate Code, shall notify the tax collector in writing that the public administrator has investigated the estate and has determined that the anticipated equity in the property after settlement of all secured liens and taxes does not warrant opening estate administration, at which time the tax sale may proceed.
