Advice for property investors on overage coventamnts from Optimise Accountants

This week, we’ve got a Guest Blog contributor from Solicitor firm Tallents – Mandy Kaur, commercial solicitor looks at why property investors need to consider the impact of overage covenants on their property businesses.

“Overage Covenants, also known as clawback provisions or development covenants, represent a potentially difficult issue for property investors who are selling and buying land.

In essence these covenants provide that a further payment will become due to the seller in the event of certain trigger events taking place within a defined period after completion of a land sale.

A simple version of the provision might state that a further fixed sum would be payable for each additional dwelling built on the land. There are, however, numerous different forms of wording, some of which rely on a more complex valuation mechanism to calculate the additional payment.

For example, a seller and a buyer might agree that if the land is developed within 25 years of completion of the sale then the buyer will pay to the seller 50% of the increase in value of the land as a result of the development.

There are a number of different points for the parties to agree, for instance the time period, what type(s) of development will trigger a payment, whether the payment is a fixed amount or a variable sum and, if so, how exactly the increase in value is to be calculated.

As a result, the legal drafting surrounding this type of provision is often complex and will increase the costs of the transaction for both parties.

Sellers and buyers will need adequate protection for a number of reasons:

For sellers, it is important to remember that the seller will have no control over whether or not any development takes place; there is no guarantee that any further payment will ever become due.

Furthermore, it is important to provide that in the event that the land is sold on again during the payment period then the successors in title to the original buyer should also be bound to make payments in the event that they develop the land.

Sellers will always need to consider what mechanisms are available to them to ensure that they receive notice of any development of the land and therefore they are in a position to claim the further payment.

For buyers, the critical issues include looking to ensure that the land can still be dealt with as freely as possible in the future – as such, buyers will want to avoid clauses that are overly restrictive of their ability to sell or lease the land.

Buyers should also bear in mind that if they did look to sell the land on it may be that a buyer would be reliant on bank lending in order to finance the purchase; in those circumstances, bank lenders will be concerned to check that the overage does not adversely affect their security, and therefore it is important to check the terms of the overage provisions carefully for any points which might raise difficulties for future funders.

There can also be complications for buyers in terms of Stamp Duty Land Tax.

A third class of persons affected by overage provisions are those who buy land that is already subject to pre-existing overage provisions.

It is vital that a buyer of land in these circumstances should understand the nature of the agreement that was put in place by their predecessors in title, and how this could affect their proposed use of the land.

Again, there can be Stamp Duty Land Tax considerations for a buyer of land in these circumstances.

All parties will need to bear in mind that there can be some uncertainty inherent in the calculation of the amount of overage payments where this involves carrying out a valuation of the land immediately before the development and then a separate valuation as a result of the development taking place.

Given that valuation is not always straightforward, there may be scope for differences of opinion as to one or both elements of this equation.

Most overage provisions contain a process for an expert valuer to be appointed if the parties cannot agree on the relevant figures to be used, but there is no guarantee for either party that a valuer will find in their favour.

As with so many of the potential issues that can arise on sales of land, all parties need to ensure that they understand the issues and consider any risks. Obtaining specialist advice as early as possible in the process can place a party in the best possible position to negotiate favourable terms going forward.
