Version Summary

This policy guide was updated from the 05/05/2025 version to include clarification on assignment for half-siblings with different mothers, information on assignment of WIC 342/385/387 petitions, and a reduced assignment dispute timeframe from two (2) weeks to five (5) business days. This policy also includes provisions allowing a Dependency Investigation (DI) Supervising Children’s Social Worker (SCSW) to confirm a change in address for assignment consideration. Several section titles were updated to clarify that assignment decisions are based on the address reported at the time of the detention/initial hearing.

POLICY

Assignment of Dependency Investigation Tasks after the Detention Hearing

In general, assignment of dependency investigation tasks depends on where the primary custodial parent(s)/legal guardian(s) (LG) was residing at the time of the Detention/Initial Hearing (Detention Hearing or Initial Hearing). The parent/LG’s physical address will supersede any other address, unless otherwise specified. If the address on the JV-140, Notification of Mailing Address is the parent/LG's physical address, then this address will be used for assignment. If the JV-140 address is an alternative address, then the assigning address will revert to the physical address. 

For situations where it is discovered that the parent’s physical address is different than what is on the JV-140 and the address has not been verified in person, the sending DI SCSW must confirm that the address is verified prior to determining the assignment. This can be done via telephone with professional staff, if applicable (i.e., shelter, treatment program, other residential program, etc.,). The address may also be confirmed by telephone or in writing (i.e., text message, etc.) with a parent. The address confirmation must be documented.  

Half siblings who share the same father but have different mothers must be assigned based on their own mother’s circumstances. These cases (with differing court case numbers) must be assigned separately. Separate assignment does not mean the case automatically follows the mother’s address. All existing address‑based assignment rules still apply.

If a detention at large was filed, and the whereabouts of the parent(s) and child(ren) are unknown, then the office that filed the detention at large will be responsible for the Dependency Investigation and report. For cases where a detention at large was filed by Emergency Response Command Post (ERCP) (2PEN cases) or Multi-Agency Response Team (MART), the Dependency Investigator (DI) assignment will belong to the corresponding Regional office where the case is assigned for Continuing Services (CS). 

As for warrant progress reports, a DI CSW will submit the report pre-disposition, and a case-carrying CSW will complete the report post-disposition. Refer to Protective Custody Warrants for additional information. 

Unless otherwise specified, the DI CSW in the identified office will write the report, as follows:
