Which legislation establishes a system of priority for registered interests in land?

The Registration of Titles Act is specifically designed to manage the registration of land titles and establish the priority of interests to establish a system of land registration. This act ensures that once an interest is registered, it has priority over subsequent interests unless otherwise noted. It creates a secure and reliable system for determining the order of interests in land, which is essential for maintaining clear and enforceable property rights. This is why the Registration of Titles Act is the correct answer.
