In some cases, two or more landowners may each own land which only has potential for development in conjunction with the land owned by the other(s). The landowners will often choose to enter what is known as a Landowners’ Agreement between themselves to provide for their co-operation and to regulate the manner in which costs and receipts are to be divided up in the event that the land collectively is allocated for development. In some cases the owners may agree to equalise the receipts and profits by reference to the extent of the gross area of their respective ownerships but different apportionments may apply in other scenarios, particularly if one owner has control of only a small area which is nevertheless vital to the proposed scheme.
