Overage Agreements Solicitors

We work with specialist surveyors to help landowners secure their future interests by:

• Ensuring the overage period is long enough to capture the full development cycle
• Protecting the overage through robust title restrictions and security
• Structuring clear and fair valuation mechanisms

Our goal is to prevent lost value, ensuring you benefit from any future uplift you are entitled to.

We assist developers by:

• Negotiating overage terms that are commercially viable and workable
• Reducing unnecessary restrictions that could harm cash flow or viability
• Clarifying trigger events to ensure certainty and avoid disputes
• Advising on how overage impacts funding, planning and disposal strategies

We help you move efficiently from acquisition to delivery, without being held back by ambiguous or onerous overage terms.

We provide due diligence support by:

• Reviewing existing overage provisions on acquisitions
• Identifying legal and commercial risks
• Advising on enforceability and practical implications for funding
• Negotiating variations where necessary

We help you understand, manage and mitigate risk, ensuring your investment remains secure.

This determines how long the overage obligation lasts, often 5, 10, 25 years or more. We ensure the period is realistic, enforceable and aligned with your development or disposal strategy.

The overage payment may be triggered by:

• Grant of planning permission
• Implementation of planning permission
• Sale of the property
• Commencement or completion of development

We help clients choose a trigger that creates certainty and fairness, avoiding future disputes.

We draft clear mechanisms for:

• Defining the base value
• Establishing the enhanced value
• Agreeing a fair percentage share
• Managing valuation disputes

Our goal is to ensure the calculation is transparent and workable for all parties.

We advise on the most appropriate form of security, including:

• Title restrictions
• Legal charges
• Positive covenants
• Guarantees and indemnities

Our team ensures that the overage is properly protected and enforceable.

An overage agreement is a legally binding arrangement where the seller of land becomes entitled to an additional payment if the land increases in value after the sale due to certain defined events, such as planning permission being granted. It ensures the seller benefits from uplift that was not reflected in the original sale price.

A well-drafted overage agreement will usually include:

• The overage period – how long the seller’s entitlement lasts
• Trigger events – what circumstances give rise to payment
• Calculation methodology – how base value, enhanced value and uplift are defined
• Percentage share – the agreed share of any uplift
• Security mechanisms – restrictions on title, charges or covenants
• Information and reporting obligations
• Dispute resolution provisions

Precision in drafting is essential to avoid ambiguity or unenforceability.

Overage clauses allow the seller to share in future value added to land after completion. The buyer (and often subsequent owners) must make an additional payment if a trigger event occurs. These clauses are typically used in land with development potential, strategic land deals, phased development and commercial disposals where future planning outcomes may significantly increase value.

Typical trigger events include:

• Grant of planning permission
• Implementation of planning permission
• Sale or disposal of the land after an uplift
• Commencement or completion of development
• Change of use

Choosing the right trigger is crucial, as it directly affects timing, valuation and enforceability.

Costs depend on the complexity of the site, the drafting required and whether negotiations are involved. Fees may include:

• Solicitors’ fees for drafting or reviewing the agreement
• Valuation fees for establishing base and enhanced values
• Land Registry fees for registering restrictions or charges

Myerson provides clear, upfront pricing tailored to the nature of the transaction.

Generally, overage payments are not tax-free. They can trigger:

• Capital Gains Tax (CGT) for sellers
• SDLT adjustments for buyers
• Occasionally, income tax implications

Tax treatment depends on the structure and timing of the arrangement, and specific tax advice should always be sought.

Specialist solicitors ensure the agreement is clear, enforceable and commercially workable. They will:

• Draft precise terms to avoid disputes
• Recommend appropriate triggers and valuation methods
• Advise on securing the seller's interest
• Review existing overage obligations in acquisitions
• Deal with negotiations between multiple parties
• Ensure compliance with contract, planning and tax considerations

Given the complexity, legal advice is highly recommended.

Overage provisions can materially affect valuation because they:

• Reduce the current market value (buyers factor in the future payment)
• Impact funding (lenders scrutinise the terms, which may affect borrowing)
• Increase valuation complexity due to the need for expert assessment of uplift
• Affect future resale if the overage is considered onerous

Correctly defined valuation mechanisms are essential to avoid disputes.

Overage agreements are usually long-term and cannot be cancelled unilaterally. They may be removed if:

• Both parties agree to a formal deed of release or variation
• The overage period expires
• It becomes unenforceable due to drafting defects or lack of proper registration

We frequently advise on negotiating releases or amendments.

To remove the overage from the title, you typically need:

• A formal release from the beneficiary
• Submission of the appropriate Land Registry application to remove restrictions or charges

The Land Registry will not remove the entry without clear evidence the overage no longer applies.

If permitted by the agreement, the benefit can be transferred to another party via:

• A deed of assignment
• Notification to the party subject to the overage
• Updating any relevant title entries

Assignments commonly occur in investment, development or estate restructuring scenarios.

Overage must be properly protected to ensure enforceability, usually through:

• A restriction on the title
• A legal charge
• Positive covenants supported by indemnities
• Additional contractual protections

Poorly protected overage risks being lost on future sales.

Often yes, but not always. Some triggers require:

• Grant of planning
• Implementation
• Sale after planning gain
• Completion of development

The agreement must specify the exact trigger — the difference between grant and implementation can substantially affect payment timing.

If an overage was intended but does not appear on the registered title, the consequences depend on:

• Whether the agreement was properly executed
• Whether future purchasers had notice of it
• Whether contractual rights still survive despite non-registration

Myerson frequently advises on rectification and enforceability issues in these scenarios.

The base value is the starting valuation of the land used to calculate uplift. It may represent:

• The market value at the time of sale
• The price paid for the land
• An adjusted figure allowing for purchaser’s costs or abnormal development costs

A clear, fair definition of base value is essential for accurate uplift calculations.
