For Families that divorce, we recommend creating a new Family record for the parent that the child does not primarily live with.
Add an Alert on both Family records to notify users of the situation and provide a link to the other family record.
Do NOT connect the child record with both Family records.
On the new Family record, you may also create a Case Stage or other status field that will categorize the record for ease in mailings and other notifications from your agency.
The "Ap 1/2 Details - Ap 1/2 Divorced" field is meant to be used for the current marital situation.
The parent which is no longer living with the child should have this checked.
