Sole Occupancy Authorities (SOAs) were created to permit livestock keepers to link different holdings which fall under their sole management and control.

All SOAs have now been withdrawn.

Cattle Tracing System Links (CTS links) have allowed keepers to link holdings if they frequently move cattle between them. Currently, movements between holdings linked on CTS do not have to be reported.

All CTS links have been withdrawn.
