63.1.

 (a) Notwithstanding any other provision of this chapter, a change in ownership shall not include the following purchases or transfers for which a claim is filed pursuant to this section:

(1) (A) The purchase or transfer of real property which is the principal residence of an eligible transferor in the case of a purchase or transfer between parents and their children.

(B) A purchase or transfer of a principal residence from a foster child to the child’s biological parent shall not be excluded under subparagraph (A) if the transferor child received that principal residence, or interest therein, from a foster parent through a purchase or transfer that was excluded under subparagraph (A).

(2) The purchase or transfer of the first one million dollars ($1,000,000) of full cash value of all other real property of an eligible transferor in the case of a purchase or transfer between parents and their children.

(3) (A) Subject to subparagraph (B), the purchase or transfer of real property described in paragraphs (1) and (2) of subdivision (a) occurring on or after March 27, 1996, between grandparents and their grandchild or grandchildren, if all of the parents of that grandchild or those grandchildren, who qualify as the children of the grandparents, are deceased as of the date of purchase or transfer. Notwithstanding any other provision of law, for the lien date for the 2006–07 fiscal year and each fiscal year thereafter, in determining whether “all of the parents of that grandchild or those grandchildren, who qualify as the children of the grandparents, are deceased as of the date of purchase or transfer,” a son-in-law or daughter-in-law of the grandparent that is a stepparent to the grandchild need not be deceased on the date of the transfer.

(B) A purchase or transfer of a principal residence shall not be excluded pursuant to subparagraph (A) if the transferee grandchild or grandchildren also received a principal residence, or interest therein, through another purchase or transfer that was excludable pursuant to paragraph (1) of subdivision (a). The full cash value of any real property, other than a principal residence, that was transferred to the grandchild or grandchildren pursuant to a purchase or transfer that was excludable pursuant to paragraph (2) of subdivision (a) and the full cash value of a principal residence that fails to qualify for exclusion as a result of the preceding sentence shall be included in applying, for purposes of paragraph (2) of subdivision (a), the one-million-dollar ($1,000,000) full cash value limit specified in paragraph (2) of subdivision (a).

(b) (1) For purposes of paragraph (1) of subdivision (a), “principal residence” means a dwelling that is eligible for a homeowners’ exemption or a disabled veterans’ exemption as a result of the transferor’s ownership and occupation of the dwelling. “Principal residence” includes only that portion of the land underlying the residence that consists of an area of reasonable size that is used as a site for the residence.

(2) For purposes of paragraph (2) of subdivision (a), the one-million-dollar ($1,000,000) exclusion shall apply separately to each eligible transferor with respect to all purchases by and transfers to eligible transferees on and after November 6, 1986, of real property, other than the principal residence, of that eligible transferor. The exclusion shall not apply to any property in which the eligible transferor’s interest was received through a transfer, or transfers, excluded from change in ownership by the provisions of either subdivision (f) of Section 62 or subdivision (b) of Section 65, unless the transferor qualifies as an original transferor under subdivision (b) of Section 65. In the case of any purchase or transfer subject to this paragraph involving two or more eligible transferors, the transferors may elect to combine their separate one-million-dollar ($1,000,000) exclusions and, upon making that election, the combined amount of their separate exclusions shall apply to any property jointly sold or transferred by the electing transferors, provided that in no case shall the amount of full cash value of real property of any one eligible transferor excluded under this election exceed the amount of the transferor’s separate unused exclusion on the date of the joint sale or transfer.

(c) As used in this section:

(1) “Purchase or transfer between parents and their children” means either a transfer from a parent or parents to a child or children of the parent or parents or a transfer from a child or children to a parent or parents of the child or children. For purposes of this section, the date of any transfer between parents and their children under a will or intestate succession shall be the date of the decedent’s death, if the decedent died on or after November 6, 1986.

(2) “Purchase or transfer of real property between grandparents and their grandchild or grandchildren” means a purchase or transfer on or after March 27, 1996, from a grandparent or grandparents to a grandchild or grandchildren if all of the parents of that grandchild or those grandchildren who qualify as the children of the grandparents are deceased as of the date of the transfer. For purposes of this section, the date of any transfer between grandparents and their grandchildren under a will or by intestate succession shall be the date of the decedent’s death. Notwithstanding any other provision of law, for the lien date for the 2006–07 fiscal year and each fiscal year thereafter, in determining whether “all of the parents of that grandchild or those grandchildren, who qualify as the children of the grandparents, are deceased as of the date of purchase or transfer,” a son-in-law or daughter-in-law of the grandparent that is a stepparent to the grandchild need not be deceased on the date of the transfer.

(3) “Children” means any of the following:

(A) Any child born of the parent or parents, except a child, as defined in subparagraph (D), who has been adopted by another person or persons.

(B) Any stepchild of the parent or parents and the spouse of that stepchild while the relationship of stepparent and stepchild exists. For purposes of this paragraph, the relationship of stepparent and stepchild shall be deemed to exist until the marriage on which the relationship is based is terminated by divorce, or, if the relationship is terminated by death, until the remarriage of the surviving stepparent.

(C) Any son-in-law or daughter-in-law of the parent or parents. For the purposes of this paragraph, the relationship of parent and son-in-law or daughter-in-law shall be deemed to exist until the marriage on which the relationship is based is terminated by divorce, or, if the relationship is terminated by death, until the remarriage of the surviving son-in-law or daughter-in-law.

(D) Any child adopted by the parent or parents pursuant to statute, other than an individual adopted after reaching the age of 18 years.

(E) Any foster child of a state-licensed foster parent, if that child was not, because of a legal barrier, adopted by the foster parent or foster parents before the child aged out of the foster care system. For purposes of this paragraph, the relationship between a foster child and foster parent shall be deemed to exist until terminated by death. However, for purposes of a transfer that occurs on the date of death, the relationship shall be deemed to exist on the date of death.

(4) “Grandchild” or “grandchildren” means any child or children of the child or children of the grandparent or grandparents.

(5) “Full cash value” means full cash value, as defined in Section 2 of Article XIII A of the California Constitution and Section 110.1, with any adjustments authorized by those sections, and the full value of any new construction in progress, determined as of the date immediately prior to the date of a purchase by or transfer to an eligible transferee of real property subject to this section.

(6) “Eligible transferor” means a grandparent, parent, or child of an eligible transferee.

(7) “Eligible transferee” means a parent, child, or grandchild of an eligible transferor.

(8) “Real property” means real property as defined in Section 104. Real property does not include any interest in a legal entity.

(9) “Transfer” includes, and is not limited to, any transfer of the present beneficial ownership of property from an eligible transferor to an eligible transferee through the medium of an inter vivos or testamentary trust.

(10) “Social security number” also includes a taxpayer identification number issued by the Internal Revenue Service in the case in which the taxpayer is a foreign national who cannot obtain a social security number.

(d) (1) The exclusions provided for in subdivision (a) shall not be allowed unless the eligible transferee, the transferee’s legal representative, or the executor or administrator of the transferee’s estate files a claim with the assessor for the exclusion sought and furnishes to the assessor each of the following:

(A) A written certification by the transferee, the transferee’s legal representative, or the executor or administrator of the transferee’s estate, signed and made under penalty of perjury that the transferee is a parent, child, or grandchild of the transferor and that the transferor is his or her parent, child, or grandparent. In the case of a grandparent-grandchild transfer, the written certification shall also include a certification that all the parents of the grandchild or grandchildren who qualify as children of the grandparents were deceased as of the date of the purchase or transfer and that the grandchild or grandchildren did or did not receive a principal residence excludable under paragraph (1) of subdivision (a) from the deceased parents, and that the grandchild or grandchildren did or did not receive real property other than a principal residence excludable under paragraph (2) of subdivision (a) from the deceased parents. The claimant shall provide legal substantiation of any matter certified pursuant to this subparagraph at the request of the county assessor.

(B) A written certification by the transferor, the transferor’s legal representative, or the executor or administrator of the transferor’s estate, signed and made under penalty of perjury that the transferor is a grandparent, parent, or child of the transferee and that the transferor is seeking the exclusion under this section and will not file a claim to transfer the base year value of the property under Section 69.5.

(C) A written certification shall also include either or both of the following:

(i) If the purchase or transfer of real property includes the purchase or transfer of residential real property, a certification that the residential real property is or is not the transferor’s principal residence.

(ii) If the purchase or transfer of real property includes the purchase or transfer of real property other than the transferor’s principal residence, a certification that other real property of the transferor that is subject to this section has or has not been previously sold or transferred to an eligible transferee, the total amount of full cash value, as defined in subdivision (c), of any real property subject to this section that has been previously sold or transferred by that transferor to eligible transferees, the location of that real property, the social security number of each eligible transferor, and the names of the eligible transferees of that property.

(D) If there are multiple transferees, the certification and signature may be made by any one of the transferees, if both of the following conditions are met:

(i) The transferee has actual knowledge that, and the certification signed by the transferee states that, all of the transferees are eligible transferees within the meaning of this section.

(ii) The certification is signed by the transferee as a true statement made under penalty of perjury.

(E) In the case of a transfer between a foster parent and foster child, the claim filed with the assessor shall include a certified copy of the court decision regarding the foster child status of the individual and a certified statement from the appropriate county agency stating that the foster child was not, because of a legal barrier, adopted by the foster parent or foster parents. Upon a request by the county assessor, the claimant also shall provide to the assessor legal substantiation of any matter certified under this subparagraph.

(2) If the full cash value of the real property purchased by or transferred to the transferee exceeds the permissible exclusion of the transferor or the combined permissible exclusion of the transferors, in the case of a purchase or transfer from two or more joint transferors, taking into account any previous purchases by or transfers to an eligible transferee from the same transferor or transferors, the transferee shall specify in his or her claim the amount and the allocation of the exclusion he or she is seeking. Within any appraisal unit, as determined in accordance with subdivision (d) of Section 51 by the assessor of the county in which the real property is located, the exclusion shall be applied only on a pro rata basis, however, and shall not be applied to a selected portion or portions of the appraisal unit.

(e) (1) The State Board of Equalization shall design the form for claiming eligibility. Except as provided in paragraph (2), any claim under this section shall be filed:

(A) For transfers of real property between parents and their children occurring prior to September 30, 1990, within three years after the date of the purchase or transfer of real property for which the claim is filed.

(B) For transfers of real property between parents and their children occurring on or after September 30, 1990, and for the purchase or transfer of real property between grandparents and their grandchildren occurring on or after March 27, 1996, within three years after the date of the purchase or transfer of real property for which the claim is filed, or prior to transfer of the real property to a third party, whichever is earlier.

(C) Notwithstanding subparagraphs (A) and (B), a claim shall be deemed to be timely filed if it is filed within six months after the date of mailing of a notice of supplemental or escape assessment, issued as a result of the purchase or transfer of real property for which the claim is filed.

(2) In the case in which the real property subject to purchase or transfer has not been transferred to a third party, a claim for exclusion under this section that is filed subsequent to the expiration of the filing periods set forth in paragraph (1) shall be considered by the assessor, subject to all of the following conditions:

(A) Any exclusion granted pursuant to that claim shall apply commencing with the lien date of the assessment year in which the claim is filed.

(B) Under any exclusion granted pursuant to that claim, the adjusted full cash value of the subject real property in the assessment year described in subparagraph (A) shall be the adjusted base year value of the subject real property in the assessment year in which the excluded purchase or transfer took place, factored to the assessment year described in subparagraph (A) for both of the following:

(i) Inflation as annually determined in accordance with paragraph (1) of subdivision (a) of Section 51.

(ii) Any subsequent new construction occurring with respect to the subject real property.

(3) (A) Unless otherwise expressly provided, the provisions of this subdivision shall apply to any purchase or transfer of real property that occurred on or after November 6, 1986.

(B) Paragraph (2) shall apply to purchases or transfers between parents and their children that occurred on or after November 6, 1986, and to purchases or transfers between grandparents and their grandchildren that occurred on or after March 27, 1996.

(4) For purposes of this subdivision, a transfer of real property to a parent or child of the transferor shall not be considered a transfer to a third party.

(f) The assessor may report quarterly to the State Board of Equalization all purchases or transfers, other than purchases or transfers involving a principal residence, for which a claim for exclusion is made pursuant to subdivision (d). Each report shall contain the assessor’s parcel number for each parcel for which the exclusion is claimed, the amount of each exclusion claimed, the social security number of each eligible transferor, and any other information the board may require in order to monitor the one-million-dollar ($1,000,000) limitation in paragraph (2) of subdivision (a). In recognition of the state and local interests served by the action made optional in this subdivision, the Legislature encourages the assessor to continue taking the action formerly mandated by this subdivision.

(g) This section shall apply to both voluntary transfers and transfers resulting from a court order or judicial decree. Nothing in this subdivision shall be construed as conflicting with paragraph (1) of subdivision (c) or the general principle that transfers by reason of death occur at the time of death.

(h) (1) Except as provided in paragraph (2), this section shall apply to purchases and transfers of real property completed on or after November 6, 1986, and shall not be effective for any change in ownership, including a change in ownership arising on the date of a decedent’s death, that occurred prior to that date.

(2) This section shall apply to purchases or transfers of real property between grandparents and their grandchildren occurring on or after March 27, 1996, and, with respect to purchases or transfers of real property between grandparents and their grandchildren, shall not be effective for any change in ownership, including a change in ownership arising on the date of a decedent’s death, that occurred prior to that date.

(i) A claim filed under this section is not a public document and is not subject to public inspection, except that a claim shall be available for inspection by the transferee and the transferor or their respective spouse, the transferee’s legal representative, the transferor’s legal representative, and the executor or administrator of the transferee’s or transferor’s estate.
