Which of the following is an example of a third party right that binds a buyer only if correctly registered?

• A. K1 Form
• B. C(i) Puisne Mortgage
• C. D(ii) Restrictive Covenants created after 1 January 1926
• D. D(iii) Equitable easements created after 1 January 1926

Answer: (C)

The essential idea is that some rights created by a third party only bind a buyer if they have been correctly registered on the land register. Under the land charges framework set in the early 20th century, certain interests must be registered to affect subsequent owners; without proper registration, the buyer takes the land free of that right.

Restrictive covenants created after 1 January 1926 fall into that category. They are registrable as land charges, so they will bind a new owner only if the covenant is correctly registered against the title. If registration is missing or faulty, the buyer is not bound by the covenant, even though it exists.

The other possibilities don’t illustrate this registration-dependent binding as clearly. A K1 form isn’t a standard example of a third-party right that binds a buyer through registration. A puisne mortgage binds as a charge on the land and isn’t described as binding only if registered in the same way. Equitable easements created after 1926 are not typically binding on a purchaser solely through registration in the same registrable-charge sense, so they don’t fit the stated pattern as cleanly.
