3. (3) The enforcement of spousal support liability of the spouse or former spouse to the extent required by the state plan under Section 11475.2 of this code and Part 6 (commencing with Section 5700.101) of Division 9 of the Family Code.

No public entity shall disclose any file, application, paper, document, or record, or the information contained therein, except as expressly authorized by this section.
2. (2) In no case shall information be released or the whereabouts of one party or the child disclosed to another party, or to the attorney of any other party, if a protective order has been issued by a court or administrative agency with respect to the former party, a good cause claim under Section 11477.04 has been approved or is pending, or the public agency responsible for establishing paternity or enforcing support has reason to believe that the release of the information may result in physical or emotional harm to the former party or the child.
3. (3) Notwithstanding any other provision of law, a proof of service filed by the district attorney shall not disclose the address where service of process was accomplished. Instead, the district attorney shall keep the address in the district attorney’s own records. The proof of service shall specify that the address is on record at the district attorney’s office and that the address may be released only upon an order from the court pursuant to paragraph (6) of subdivision (c). The district attorney shall, upon request by a party served, release to that person the address where service was effected.

(c) Disclosure of the information described in subdivision (b) is authorized as follows:

1. (1) All files, applications, papers, documents, and records as described in subdivision (b) shall be available and may be used by a public entity for all administrative, civil, or criminal investigations, actions, proceedings, or prosecutions conducted in connection with the administration of the child and spousal support enforcement program approved under Part D (commencing with Section 651) of Subchapter IV of Chapter 7 of Title 42 of the United States Code, and any other plan or program described in Section 303.21 of Title 45 of the Code of Federal Regulations and to the county welfare department responsible for administering a program operated under a state plan pursuant to Subpart 1 or 2 of Part B or Part E of Subchapter IV of Chapter 7 of Title 42 of the United States Code.

5. (5) Public records subject to disclosure under the California Public Records Act (Division 10 (commencing with Section 7920.000) of Title 1 of the Government Code) may be released.
6. (6) After a noticed motion and a finding by the court, in a case in which establishment or enforcement actions are being taken, that release or disclosure to the obligor or obligee is required by due process of law, the court may order a public entity that possesses an application, paper, document, or record as described in subdivision (b) to make that item available to the obligor or obligee for examination or copying, or to disclose to the obligor or obligee the contents of that item. Article 9 (commencing with Section 1040) of Chapter 4 of Division 8 of the Evidence Code shall not be applicable to proceedings under this part. At any hearing of a motion filed pursuant to this section, the court shall inquire of the district attorney and the parties appearing at the hearing if there is reason to believe that release of the requested information may result in physical or emotional harm to a party. If the court determines that harm may occur, the court shall issue any protective orders or injunctive orders restricting the use and disclosure of the information as are necessary to protect the individuals.
7. (7) To the extent not prohibited by federal law or regulation, information indicating the existence or imminent threat of a crime against a child; location of a concealed, detained, or abducted child; or the location of the concealing, detaining, or abducting person, may be disclosed to any district attorney, any appropriate law enforcement agency, or to any state or county child protective agency, or may be used in any judicial proceedings to prosecute that crime or to protect the child.
