Considering the sale of land but keen to retain some influence over its future? For farming families and rural estates, a land sale is often about more than simply achieving the best price. The land may have been in the same ownership for generations, adjoin retained farmland, support the wider estate strategy, or have long-term development potential that could significantly increase its value.
A number of legal mechanisms can help preserve a degree of control or allow a seller to benefit from future opportunities after a sale. Whether the aim is to share in future development value, protect the operation of a retained farming business, or maintain influence over strategically important land, careful planning at the outset can be invaluable. Below is an overview of some of the most commonly used options.
Overage
Overage is commonly used where land has future development potential, for example, where agricultural land lies on the edge of a village or near an expanding settlement. It entitles the seller (or a nominated beneficiary) to receive an additional payment if the value of the land increases as a result of a specified trigger event, such as the grant or implementation of planning permission.
Overage is often most effective where there is no objection to development, but there is a desire to share in any future uplift in value. However, overage provisions can be complex, and both the commercial terms and legal drafting need careful consideration. It is important to strike the right balance, ensuring that the buyer retains sufficient incentive to pursue planning permission or carry out development.
Restrictive covenants
Restrictive covenants are often attractive where the primary objective is to limit or prevent certain uses of a property, including development. They may be used to preserve important views, prevent uses that might interfere with farming operations, or maintain the character of a rural estate. To be enforceable, however, the seller will usually need to retain neighbouring land that benefits from the restriction, as the covenant must “touch and concern” the retained land.
This option is most appropriate where the primary objective is to prevent development rather than share in any increase in value.
Restrictive covenants are often more straightforward and cost-effective to implement than overage arrangements, although they do not provide any financial participation in future development gains.
Ransom strips
A ransom strip involves retaining a narrow strip of land along the boundary of the land being sold and may be encountered where agricultural land has strategic development potential. It can be a valuable tool where access across the sold land may be required to unlock the development potential of adjoining land in the future.
If a developer subsequently needs rights over the retained strip, the landowner may be able to negotiate a premium payment. As an alternative to retaining a physical strip of land, an access overage arrangement can be agreed with the buyer. This would provide for an additional payment if the land were ever used to access or facilitate development on neighbouring land.
Pre-emption rights
A pre-emption agreement gives the seller a right of first refusal if the buyer decides to sell the property in the future. Before offering the land for sale on the open market, the buyer must first offer it back to the seller, typically at market value.
This can be particularly useful where adjoining land is retained as part of a wider farming operation or estate and there is a desire to retain some influence over future ownership. It may also help with succession planning, allowing land to be sold to release capital, whilst preserving the opportunity to re-acquire it for a future generation.
Where the repurchase price is based on market value, it is worth remembering that any planning permission obtained after the original sale could significantly increase the cost of buying the property back.
Which option is right?
For farmers, landowners and rural estates, several options are available to retain a degree of control or secure future benefits after the sale of land. The most appropriate solution will depend on the objectives, whether these are:
- sharing in future development value
- preventing or restricting development
- retaining leverage over future access arrangements
- ensuring an opportunity to buy the land back in the future
Each mechanism has its own advantages, limitations and drafting considerations. Taking specialist legal advice at an early stage can help ensure that the arrangements properly reflect the long-term interests of the farming business, rural estate or family holding while also maximising the value and strategic opportunities with the land being sold.
