Section 55(1) of the Transfer of Land Act 1893 (WA) forbids the registration of a beneficial interest on title.

This section reads:

The Registrar shall not enter on a certificate of title notice of any trusts other than those set out in the body of the original Crown grant or certificate of title or contained or referred to in the transfer, or the ministerial order for the conveyance, of the relevant Crown land into the fee simple.
