Subsequent Registration of Mares which suffer an untimely death:
It is possible to subsequently register mares which die before the date on which they could have been presented for classification in the year of the birth of the foal. This possibility merely fulfils the purpose of issuing pedigree papers for the last born foal. The Committee decides in each case if and in which section the subsequent registration should take place. This is only applicable to Hanoverian mares. The possibility of mares dying before they can be classified and their foals registered should always be uppermost when deciding when to classify the mare. Classifying the mare in foal or before serving will eliminate this worry.

Upgrading of Mares in the Stud Book:
Hanoverian mares which are registered in one section of the Stud Book can, on well reasoned application, be presented again to the Evaluation Commission at a central venue. The Commission or Classifier then decides whether or not to upgrade the mare by one section. A subsequent alteration of the pedigree papers of existing progeny shall not be made.

Withdrawal of Mares:
Owners should advise the Society as soon as possible if the mare to be presented is to be withdrawn. The Committee will decide if a refund of classification fees is to be made. Once classified, it is the owner's responsibility to advise the Society if the mare dies, retires or is to be deregistered. Owners should also advise when they receive their membership renewal if the mare is to be inactive in the upcoming year. If the active fee is paid, owners cannot claim a
refund if they change their mind and decide not to breed their mare. However, if the inactive fee is paid and the owner subsequently decides to breed the mare, the difference in fees must be paid. If the owner's membership lapses for a period of two years, the mare will be deregistered. The owner will be notified in writing of such and have the opportunity to pay their outstanding fees.

Re-registering Mares:
Once a mare has been deregistered, either at the owner's request or due to a lapse in payment of dues, it may be re-registered again following written application by the owner. If the same owner has requested re-registration, they are liable for the cost of classification fees of $110 plus $10 inactive fee for each year the mare remained unregistered. They do not have to present the mare for classification again and, once accepted for re-registration, the mare retains her previous Stud Book status. If the mare has changed owners, the new owner is only liable for a change of ownership fee of $15 plus $10 for each year the mare was unregistered.
