If the California real estate you want to inherit has a value of less than $20,000, then you do not have to go through a probate.
Here is what California law provides as described in Probate Code Section 13200:
13200. (a) No sooner than six months from the death of a decedent,
a person or persons claiming as successor of the decedent to a particular item of property that is real property may file in the superior court in the county in which the decedent was domiciled at the time of death, or if the decedent was not domiciled in this state at the time of death, then in any county in which real property of the decedent is located, an affidavit in the form prescribed by the Judicial Council pursuant to Section 1001 stating all of the following:
(1) The name of the decedent.
(2) The date and place of the decedent’s death.
(3) A legal description of the real property and the interest of the decedent therein.
(4) The name and address of each person serving as guardian or conservator of the estate of the decedent at the time of the decedent’
s death, so far as known to the affiant.
(5) “The gross value of all real property in the decedent’s estate located in California, as shown by the inventory and appraisal attached to this affidavit, excluding the real property described in Section 13050 of the California Probate Code, does not exceed twenty thousand dollars ($20,000).”
