The registrar may require production of documents for the purposes of proceedings before him (section 75) and may make orders as to costs (section 76). A person must not exercise the right to lodge a caution against first registration, to apply for a notice or restriction, or to object to an application without reasonable cause; the duty is owed to anyone who suffers damage as a result and is actionable (section 77). Notice of a trust does not affect the registrar (section 78).
