4. The Keeper has no authority to be prescriptive on the scale of plan employed for conveyancingpurposes. However, as a matter of practice he will make up a title plan for each registered interestin the Land Register using the largest scale of ordnance map available. Accordingly, any deed planproduced from a similar source is unlikely to cause concern. The applicant may present a planlarger than the three ordnance map scales used by the Keeper (1:500 is not an uncommon scalefor deed plans) in order to show detail which would not be clear on a smaller scale. The Keeper,depending on what he sees as the title requirements for the title sheet and land certificate, mayincorporate a copy of this plan in the title sheet as supplementary to the title plan. Alternatively,the Keeper may prepare an enlarged plan or an insert to show a particular feature. Both theseprocedures can often help to overcome the lack of sufficient detail on the ordnance map. If theKeeper considers that the detail on the applicants 1:500 (or such larger scale) plan is unnecessaryfor the purpose of registration, he will prepare the relevant title and certificate plans at the normalappropriate scale. Any larger scale plan will be subject to the indemnity limitations imposed bysection 12(3)(d).5. Where a plan has to be prepared to enable the Keeper to identify the subjects, it should not be ona smaller scale than 1:1250, 1:2500 or 1:10,000 if the subjects are urban, rural or moorland typeproperties respectively. In such cases the plan should preferably be based on the ordnance map.It should be remembered that, even with continuous revision by the Ordnance Survey, the latestmap information available may not necessarily reflect the situation on the ground.6. The requirements to identify subjects sufficiently relate not merely to land but also to such otherinterests in land as salmon fishings or minerals. In the case of minerals which are severed from thelands, sufficient identification may have to include the lands under which the minerals are to befound and, in certain cases, a strata plan. Where minerals are being conveyed as a separatetenement, the registration requirements should be discussed in detail with the Keeper.7. If any parts of the subjects are affected by particular rights or burdens, sufficient supportinginformation must be given to allow the Keeper to delineate specific areas on the certificate plan.8. Where no physical features (fences, walls, hedges, ditches or the like) exist on the ground, theKeeper must be informed, on application for registration, about the dimensions of the land. Theboundaries must be related to existing physical detail on the ordnance map so that the propertycan be clearly and accurately defined. This problem will arise most frequently in the case of newproperties on a developing housing estate. The procedures which are available for having a plan ofsuch an estate approved by the Keeper before applications are made to register the house plotsare discussed at paragraph 4.37 et seq.Form 1 - (Part B - questions 1-3)4.15 The Form 1 was revised in 1995 in an effort to speed up the registration process by ensuring thatany problems are highlighted and resolved prior to the application being made. In particular,Questions 1-3 of Part B of the Form 1 place greater emphasis on the need to identify the legal extentof a property and compare it with the occupied extent.
