Subject to limited exceptions, including caveats registered pursuant to section 148.1 of The Real Property Act, the district registrar will not accept caveats by registered owners against their own land.
This restriction includes caveats presented by registered owners claiming an equitable interest in their own land. Registered owners are presumed to benefit from their ownership. Therefore, a caveat giving notice of an equitable interest of the registered owner in their own land does not disclose any additional interest that the title does not already encompass.
