No. A survey plan is not a sine qua non. Of course some description is necessary to make a disputed land ascertainable. Where the land has been so sufficiently described that a Surveyor can produce a survey map of the land from the details of the description, a survey plan would not a necessity.
A survey plan would also not be necessary where the identity of the land is not in dispute. Where there is no difficulty in identifying a land in dispute, a declaration of title may be made without the necessity of tying it to a survey plan. Nadi V. Oseni (2003) 48 WRN 12 CA; Elias V.
