The appointed attorney in CARES should always match the appointed attorney in court (per the order of appointment). Whenever the attorney of record changes in court, the previous attorney of record must end their appointment in CARES and the new attorney of record should create their own, new appointment in CARES, thereby reflecting what the court did and when. This is true regardless of whether attorneys share the same office.
For data entry, substituting on a case in CARES is no different than creating any appointment. As usual, neither attorney needs to wait for the other to complete their steps in CARES. Click here for more tips on finding and setting up the case appointment in CARES.
The accuracy of each of your child party's dates and your roles is always very important for CARES and CARES reports. Do not use another attorney's start date. And please note, the CJD's requirements such as the D&N 30-day initial visit become the responsibility of the new attorney of record, even within the same office. (I.e., using the 30-day example, the previous D&N attorney's initial visit does not exempt the new/sub attorney from making their own initial visit within 30 days.)
Please note, the attorney of record does not "request access" to the former attorney's appointment. The reasons to access another office's appointment, e.g. as mentor, litigation support, or providing coverage, do not apply to the new attorney of record or subbing in. Requesting access would also prevent the new office from entering activities--the former attorney's appointment will close very soon (after anyone working on the case, including CCs, are finished entering their activities).
