A restriction regulates the circumstances in which a disposition may be entered in the register (prohibiting entries indefinitely, for a period or until a condition is met). The registrar may enter a restriction to prevent invalidity or unlawfulness, to secure overreaching or to protect a right or claim (section 42); the proprietor, a person with consent or a person with sufficient interest may apply (section 43); where two or more persons are registered as proprietor the registrar must enter the standard restriction securing overreaching (section 44); the court may order entry (section 46); and withdrawal is under section 47. Notifiable applications are served on the proprietor (section 45).
