Adding a parent parcel
You can use the Parcel InfoViewer to indicate any parent parcels that the current parcel was created out of. A parent parcel is an older parcel out of which the current parcel has been created, such as a large parcel that was subdivided or one of several parcels that were joined to create a new parcel. You can also add a child parcel. Setting up parent and child relationships among your parcels helps your agency track parcels as they change their boundaries through subdivision or joining.
