Property Development Agreement Solicitors

Expert Development Agreement Solicitors

A property development project can involve several parties, substantial capital and obligations extending over months or years.

The development agreement is often the document that brings those commercial arrangements together.

It can establish:

What is to be developed

Who is responsible for delivering it

When works must be carried out

How costs are allocated

How the project is funded

What approvals are required

How development standards are measured

What happens if the project is delayed

How completed property is occupied or disposed of

What happens if a party defaults

At Knights & Shah Solicitors, we advise developers, landowners, investors and businesses on negotiating and structuring development agreements that reflect the commercial reality of the project.

Our work can include:

• Development agreements
• Landowner and developer agreements
• Conditional development arrangements
• Development obligations
• Development management arrangements
• Collaboration agreements
• Agreements for lease
• Pre-let development arrangements
• Development milestones
• Development funding provisions
• Infrastructure and access arrangements
• Site assembly issues
• Rights and easements
• Development disposals
• Default and termination provisions

The precise structure depends upon who owns the land, who is providing the capital and expertise, and what each party expects to receive from the completed development.

What Is a Property Development Agreement?

“Development agreement” is a broad commercial term rather than one single standard document.

It can describe an agreement under which a developer undertakes to develop land or property in accordance with an agreed structure and set of obligations.

Depending upon the project, the parties may include:

• Landowner
• Developer
• Investor
• Funder
• Purchaser

Commercial tenant

Joint venture vehicle

Other project participants

The agreement may sit alongside other documents such as:

• Land transfer
• Lease
• Agreement for lease
• Building contract
• Joint venture agreement
• Funding agreement
• Easement
• Licence
• Planning documentation

Development management agreement

These documents need to operate coherently rather than being negotiated in isolation.

Who We Advise

We can advise:

Commercial property developers

Landowners

Property investors

Development companies

SPVs

Corporate occupiers

Commercial landlords

Businesses commissioning development

Joint venture participants

Our role depends upon the client's position within the project.

A landowner protecting the long-term value of its land has different priorities from a developer responsible for funding and delivering the development.

Structuring the Development Agreement

The legal structure should begin with the commercial objective.

Important questions can include:

Who owns the land during development?

Who controls the project?

Who obtains planning permission?

Who funds the works?

Who carries development risk?

Who appoints the professional team?

Who approves changes?

What happens when the development is completed?

How is profit or development value realised?

What happens if the project fails?

These issues should be established before detailed drafting begins.

Development Obligations

The agreement should define what the developer is required to deliver.

Depending upon the project, obligations may concern:

Demolition

Construction

Refurbishment

Infrastructure

Access

Utilities

Landscaping

Fit-out

Estate works

Common areas

Compliance with agreed plans and specifications

Obtaining approvals

Practical completion

Ambiguous development obligations can create disputes over whether the developer has delivered what was originally promised.

The scope of the project should therefore be defined as clearly as reasonably possible.

Plans, Specifications and Development Standards

Development obligations frequently refer to agreed:

Drawings

Plans

Specifications

Employer's requirements

Design standards

Construction standards

The agreement may also need to establish a mechanism for dealing with changes.

This can include:

• Who can propose a variation
• Who must approve it
• Whether approval can be withheld
• Cost consequences
• Effect on programme
• Effect on the completed property

The legal documentation should work alongside the technical documents used by the development team.

Planning and Development Agreements

Planning can be fundamental to a development project.

The agreement may need to address:

Who is responsible for planning applications

Who controls the planning strategy

What constitutes an acceptable planning permission

Planning conditions

Appeals

Amendments

Community Infrastructure Levy considerations

Planning obligations

Timescales

Costs

Where specialist planning-law advice is required, this should be coordinated with the client's planning consultants or specialist planning advisers.

KSS's role is focused on the commercial property and development transaction rather than presenting planning law as a standalone specialism.

Conditions Precedent

A development agreement may not become fully operative until specified conditions have been satisfied.

These might concern:

Planning permission

Land acquisition

Funding

Third-party consent

Vacant possession

Access

Infrastructure

Title matters

Other project approvals

The agreement should establish:

Who is responsible for satisfying each condition

Required standard

Relevant deadline

Whether a party can waive it

Longstop date

Consequences if the condition is not satisfied

This can prevent uncertainty over when the parties become fully committed.

Development Milestones

Larger developments often need measurable milestones.

These may include:

• Site acquisition
• Planning approval
• Start on site
• Completion of infrastructure
• Construction stages
• Practical completion
• Tenant fit-out
• Disposal
• Milestones may be linked to:
• Funding
• Payments
• Drawdowns
• Approvals
• Longstop dates
• Termination rights

The agreement should define the relevant milestone sufficiently clearly for the parties to know when it has been achieved.

Longstop Dates

A longstop date establishes the point by which a specified event must occur.

This can be important where a party does not want to remain indefinitely committed to a project that has stalled.

Longstop provisions may apply to:

Planning

Acquisition

Commencement

Construction

Practical completion

Other conditions

The agreement should also deal with circumstances in which the date can be extended.

Development Programme and Delay

Development projects do not always proceed according to the original timetable.

The agreement should therefore consider:

Development programme

Target dates

Longstop dates

Extensions

Delays outside a party's control

Consequences of developer delay

Reporting requirements

Remedial rights

The appropriate approach depends upon the project and the extent to which timing is commercially critical.

Funding the Development

The agreement should be considered alongside the project's funding arrangements.

Funding may come from:

Developer equity

Bank finance

Investor capital

Joint venture funding

Forward funding

Staged payments

Other development finance

A lender may require security over the land and project.

Funding documentation can also impose requirements relating to:

Development milestones

Cost overruns

Drawdowns

Monitoring

Pre-lets

Practical completion

Disposal

Development and finance documents therefore need to work together.

Our dedicated Commercial Property Finance service is available at:

https://knightsshahsolicitors.com/commercial-property/transactions/commercial-property-finance/

Development Costs and Cost Overruns

The parties should understand who carries the risk if the project costs more than anticipated.

The agreement may address:

Development budget

Approved costs

Cost overruns

Contingency

Additional funding

Unforeseen works

Infrastructure expenditure

Professional fees

The allocation of cost risk can materially affect the economics of the development.

Landowner Protection

A landowner allowing another party to develop its property may require protection concerning:

Quality of development

Timing

Planning

Insurance

Funding

Site security

Compliance with law

Development standards

Changes to plans

Disposal

Default

The landowner may also need rights to:

Receive information

Inspect progress

Approve specified changes

Enforce milestones

Terminate in defined circumstances

The appropriate protections depend upon how much control the landowner intends to retain.

Developer Protection

A developer also needs sufficient rights to deliver the project.

These can include:

• Site access
• Construction access
• Survey rights
• Rights to carry out works
• Utility rights
• Rights to submit applications
• Rights to enter into project documents
• Rights to market or pre-let
• Protection against inconsistent dealings by the landowner

A development agreement that imposes obligations without granting the rights necessary to perform them can create significant project risk.

Access During Development

Construction may require access beyond the development site itself.

The project should establish whether adequate rights exist for:

Construction vehicles

Cranes

Scaffolding

Deliveries

Contractors

Maintenance

Emergency access

Temporary works

Where access crosses third-party land, separate rights or agreements may be required.

Easements, Services and Utilities

A completed development may need permanent legal rights for:

Access

Drainage

Electricity

Water

Gas

Telecommunications

Fibre

Maintenance

Support

Temporary rights may also be needed during construction.

These requirements should be identified before the development reaches an advanced stage.

Retrofitting missing rights later can be considerably more difficult.

Restrictive Covenants and Third-Party Rights

A development agreement cannot itself eliminate third-party rights affecting the land.

The site may be subject to:

Restrictive covenants

Easements

Rights of way

Rights to light

Occupational rights

Title restrictions

Charges

The development agreement should therefore be considered alongside proper title and development due diligence.

Where third-party rights create a material obstacle, the project may require separate negotiation, release, variation, insurance or specialist contentious advice.

Rights to Light

A proposed development may potentially affect rights enjoyed by neighbouring properties.

Rights-to-light risk should be considered particularly where the proposed development is:

Dense

Tall

Close to neighbouring buildings

Located in an established urban environment

Specialist surveyor input may be required alongside legal advice.

Site Assembly and Development Agreements

Some developments depend upon several parcels of land being brought together.

The development structure may therefore need to coordinate:

Multiple owners

Option agreements

Conditional acquisitions

Access rights

Ransom strips

Easements

Existing leases

Infrastructure land

The development agreement should reflect the dependencies between these interests.

Our dedicated Site Acquisition & Assembly service is available at:

https://knightsshahsolicitors.com/commercial-property/property-development/development-site-acquisitions-site-assembly/

Development Agreements and Joint Ventures

Where two or more parties share ownership, funding, expertise and development returns, the project may require a joint venture structure rather than simply a bilateral development agreement.

A joint venture may regulate:

Equity

Funding

Profit

Governance

Decision-making

Development obligations

Deadlock

Exit

The property and corporate documentation should be coordinated.

Our dedicated page is:

https://knightsshahsolicitors.com/commercial-property/property-development/joint-venture-agreements/

Development Management Agreements

In some projects, a developer or development manager is appointed to manage delivery without necessarily owning the development site.

A development management agreement may deal with:

Scope of services

Development manager's authority

Reporting

Professional team

Budget

Programme

Development management fee

Incentive arrangements

Approval thresholds

Termination

The agreement should clearly distinguish between decisions the manager can make and matters reserved to the landowner or investor.

Agreements for Lease and Pre-Lets

A development may be secured by an incoming commercial tenant before construction is complete.

An agreement for lease can bind landlord and tenant to enter into a lease once specified development conditions are satisfied.

It may address:

Development works

Specification

Practical completion

Measurement

Access for fit-out

Rent

Rent-free period

Longstop date

Defects

Lease terms

HMRC's current SDLT guidance confirms that an agreement for lease can itself have SDLT consequences where it is substantially performed before the lease is completed.

The agreement for lease, development obligations and occupational lease therefore need to be coordinated carefully.

Pre-Let Development Projects

Securing a tenant before completion can support:

Development funding

Investment value

Forward sale

Project viability

The developer needs to ensure that what is promised to the tenant is consistent with:

Planning

Construction programme

Funding

Development specification

Land rights

Proposed completion date

Conflicting obligations across different documents can create significant exposure.

Forward Funding and Forward Purchase Arrangements

Some developments involve an investor committing to acquire or fund the development before completion.

The transaction may include:

• Land acquisition
• Development agreement
• Funding payments
• Development obligations
• Monitoring
• Practical completion
• Conditions
• Longstop dates
• Transfer on completion

The allocation of development and funding risk needs to be documented carefully.

Practical Completion

Practical completion can trigger significant legal and financial consequences.

Depending upon the project, it may trigger:

Payment

Completion of land transfer

Commencement of lease

Rent commencement

Release of retention

Forward purchase completion

Other contractual rights

The development agreement should establish:

Who certifies practical completion

Applicable standard

Notice procedure

Whether minor defects prevent completion

Dispute mechanism

The definition should align with the project's construction documentation where appropriate.

Defects and Outstanding Works

Practical completion does not necessarily mean that every minor item has been completed.

The agreement may need to address:

Snagging

Defects

Rectification

Retention

Timescale

Access after completion

Final certification

These provisions should work alongside the relevant building contract and professional appointments.

Insurance and Risk

The development agreement should identify who is responsible for appropriate insurance during the project.

Depending upon the structure, this may include:

• Existing structures
• Construction works
• Public liability
• Professional risks
• Other project-specific cover

The legal documentation should align with the project's construction and funding arrangements.

Professional Team and Third-Party Rights

Development projects can involve:

Architects

Engineers

Surveyors

Contractors

Project managers

Other consultants

Funders, purchasers or tenants may require collateral warranties or other rights against members of the professional team.

These requirements should be identified early rather than after the appointments and building contract have already been entered into.

Where specialist construction-law advice is required, this should be coordinated with an appropriate specialist rather than presenting KSS's development-property service as a standalone construction-law practice.

Change Control

Projects evolve.

The development agreement should therefore establish how material changes are approved.

Changes may concern:

Design

Specification

Planning

Programme

Budget

Layout

Use

Infrastructure

The agreement may distinguish between:

Changes developer can make freely

Changes requiring consultation

Changes requiring consent

Prohibited changes

This can preserve appropriate flexibility without removing necessary control.

Reporting and Monitoring

A landowner, investor or funder may require ongoing visibility over the project.

The agreement can provide for:

Progress reports

Budget reports

Programme updates

Site inspections

Planning updates

Notification of material problems

Reporting requirements should be proportionate to the party's financial and legal exposure.

Default and Remedies

A development agreement should anticipate what happens when things go wrong.

Default provisions may deal with:

Failure to fund

Failure to develop

Material delay

Insolvency

Breach of development obligations

Failure to obtain required consent

Abandonment of the project

Potential remedies may include:

• Notice to remedy
• Suspension
• Step-in rights
• Damages
• Termination
• Other agreed contractual remedies

The remedies need to fit the structure of the transaction.

Step-In Rights

In certain funded or investment development structures, another party may require the ability to intervene if the developer defaults.

Step-in arrangements need careful drafting because they can affect:

Landowner

Developer

Funder

Contractor

Professional team

The underlying project documents should be coordinated so that the right is capable of operating in practice.

Termination of a Development Agreement

Termination provisions should establish:

Events permitting termination

Required notice

Cure periods

Consequences

Treatment of the land

Existing works

Documents

Intellectual property

Payments

Third-party contracts

Ending the development agreement does not necessarily resolve every property, funding or construction relationship associated with the project.

The consequences therefore need to be considered across the transaction.

Development Agreement Disputes

Disputes can arise over:

Scope of development obligations

Delay

Milestones

Costs

Variations

Practical completion

Quality

Payments

Default

Termination

The agreement should include an appropriate dispute-resolution mechanism.

Where a dispute becomes contentious, related advice can be coordinated through our Commercial & Property Litigation practice and, where necessary, an appropriate construction-law specialist.

Protecting Development Rights at HM Land Registry

Depending upon the nature of the agreement and the rights created, appropriate Land Registry protection may need to be considered.

HM Land Registry maintains procedures for notices and restrictions protecting interests affecting registered land, and restrictions can control whether a disposition may be registered unless specified requirements are satisfied.

The appropriate method depends upon the particular agreement and interest created.

Important 2026–2027 Contractual Control Rules

There is also an important forthcoming transparency regime for certain agreements controlling land.

The Provision of Information (Contractual Control) (Registered Land) Regulations 2026 have been made and will come into force on 6 April 2027.

The regime concerns certain contractual rights controlling the development or disposal of registered land, including qualifying:

Options

Conditional contracts

Pre-emption rights

Certain rights associated with promotion agreements

The government states that information about qualifying rights will need to be submitted digitally to HM Land Registry through a regulated conveyancer. Certain agreements entered into after the Regulations were made but before commencement are also brought within the transitional reporting regime.

Not every development agreement falls within this regime. The substance of the rights created, duration and applicable exemptions need to be considered.

This is particularly relevant when a development structure gives a party contractual control over land without transferring ownership immediately.

SDLT and Development Agreements

Development structures can produce different SDLT consequences depending upon what the documents actually do.

Issues can arise where a transaction combines:

Land acquisition

Development obligations

Agreements for lease

Construction obligations

Conditional contracts

Surrender and regrant

Other consideration

HMRC's current guidance emphasises that where land is sold together with associated construction obligations, the commercial substance of the transaction is relevant when determining chargeable consideration.

We identify property-transaction tax issues arising from the legal structure and coordinate with specialist tax advisers or accountants where detailed tax advice is required.

VAT and Development Transactions

VAT can also materially affect development transactions.

Relevant issues may include:

• Option to tax
• Land acquisition

Development payments

Construction

Occupational leases

Disposal

The tax treatment depends upon the specific transaction.

Development documentation should therefore be coordinated with appropriate tax advice rather than treating VAT as an afterthought.

Development Exit Strategy

The legal structure should take account of how the client ultimately intends to realise value.

The exit may involve:

Sale of completed development

Forward sale

Investment sale

Occupational leases

Plot sales

Refinancing

Retention as an investment

Different exit strategies can require different rights and documentation during the development stage.

Thinking about the exit at the beginning can prevent the legal structure from becoming an obstacle later.

The Development Agreement Process

Step 1 — Establish the Project Structure

We identify the parties, land, commercial objectives, funding and proposed development.

Step 2 — Review Heads of Terms

The principal commercial arrangements are considered before detailed drafting.

Step 3 — Property Due Diligence

Title, access, rights, restrictions, occupiers and development constraints are reviewed.

Step 4 — Identify Conditions

Planning, funding, acquisition and other conditions are established.

Step 5 — Define Development Obligations

The development scope, standards, programme and responsibilities are agreed.

Step 6 — Allocate Risk

Costs, delay, funding, approvals and other project risks are addressed.

Step 7 — Coordinate Project Documents

The development agreement is aligned with the acquisition, funding, lease and other relevant documentation.

Step 8 — Negotiate and Complete

The agreement is negotiated and entered into once the parties are satisfied with the legal and commercial structure.

Step 9 — Development Phase

Milestones, approvals, variations and reporting are managed under the contractual framework.

Step 10 — Practical Completion

The contractual completion process is followed.

Step 11 — Occupation or Disposal

Leases, transfers or other exit documentation are completed.

Step 12 — Registration and Post-Completion

Relevant Land Registry and other post-completion requirements are addressed.

Common Development Agreement Risks

Problems can arise where:

Development obligations are unclear

Plans and specifications conflict

Planning responsibility is uncertain

Funding and development documents do not align

Access rights are inadequate

Utility rights are missing

Milestones are poorly defined

Change-control provisions are impractical

Cost overruns are not allocated

Practical completion is unclear

Longstop dates are unrealistic

Existing occupiers prevent development

Third-party rights are overlooked

Termination consequences are inadequately documented

Exit strategy has not been considered

The objective of the development agreement is to allocate these risks before they become disputes.

A Commercial Approach to Development Agreements

A development agreement needs to work as a commercial project document, not simply as a legal contract.

For a developer, we consider:

Does the developer have the rights needed to deliver the scheme?

Is there sufficient flexibility to deal with project changes?

Are funding and planning dependencies properly reflected?

What happens if the programme slips?

Can the completed development be sold, leased or refinanced efficiently?

For a landowner or investor:

Is the required development clearly defined?

How is quality controlled?

How is progress monitored?

What happens if the developer fails?

Is the landowner adequately protected during construction?

How and when is value realised?

The agreement should answer these questions before substantial capital is committed.
