Conditions Subsequent
Full Overview Of Conditions Subsequent

Conditions subsequent are a critical concept in contract law and real property transactions. Unlike conditions precedent, these conditions come into effect after the formation of a contract or conveyance and can potentially alter or extinguish rights and obligations already in place.

Understanding conditions subsequent is essential for solicitors, businesses, and individuals involved in contractual agreements or property transactions. This overview aims to provide a comprehensive understanding of conditions subsequent, their applications, legal implications, and practical considerations.

What are Conditions Subsequent?

Conditions subsequent are contractual clauses that specify events or actions that, if they occur or fail to occur after the execution of a contract or transfer of property, may result in the modification or termination of obligations and rights under the agreement. When triggered, these conditions are essentially future events that have the power to alter the legal standing of the parties involved.

For example, in a property lease agreement, a condition subsequent might stipulate that if the lessee fails to maintain the property in good repair, the lessor has the right to terminate the lease. Similarly, in a business contract, a condition subsequent could state that if a party fails to secure financing within a specified period, the contract becomes void.

Key Characteristics of Conditions Subsequent

Temporal Aspect

The defining feature of conditions subsequent is their occurrence after the initial formation of the contract. This temporal aspect distinguishes them from conditions precedent, which must be satisfied before a contract becomes effective. The occurrence of the specified event under a condition subsequent can lead to the modification or cessation of contractual obligations.


Conditions subsequent are inherently contingent. They rely on the occurrence or non-occurrence of an uncertain future event. This uncertainty makes the fulfilment of conditions subsequent a matter of probability rather than certainty, adding a layer of risk to contractual agreements.

Legal Consequences

The fulfilment or breach of a condition subsequent has significant legal consequences. Depending on the contract’s terms, it may lead to the termination of the contract, the reversal of previously transferred rights, or the imposition of additional obligations. The specific consequences depend on how the condition subsequent is framed within the contract.

Applications of Conditions Subsequent

Conditions subsequent are prevalent in various types of contracts and transactions. Their applications can be broadly categorised into the following areas:

Real Property Transactions

In real property law, conditions subsequent are often included in deeds and leases. For example, a deed might convey property to a grantee with the condition that the property must be used for a specific purpose, such as educational or charitable activities. If the grantee fails to adhere to this condition, the property may revert to the grantor or another designated party.

Commercial Contracts

In commercial contracts, conditions subsequent can protect parties from unforeseen circumstances that may impact the feasibility or desirability of continuing the agreement. For instance, a supplier agreement might include a condition subsequent that allows the buyer to terminate the contract if the supplier fails to meet specified quality standards over a period.

Employment Agreements

Employment contracts may incorporate conditions subsequent to address situations where ongoing employment depends on certain conditions being met. An example could be an academic tenure agreement, where continued employment is contingent on the employee securing specific research grants or publishing work in peer-reviewed journals.

Insurance Policies

Insurance contracts often include conditions subsequent, particularly regarding the obligations of the insured to notify the insurer of certain events. For instance, a health insurance policy may require the insured to report major medical procedures within a specified timeframe. Failure to comply with this condition could result in denying coverage for related expenses.

The legal implications of conditions subsequent can be profound, affecting the rights and obligations of the parties involved. Several key legal considerations arise when dealing with conditions subsequent:


For a condition subsequent to be enforceable, it must be clearly and unambiguously stated within the contract. Ambiguities in the wording of the condition can lead to disputes and challenges in court. Courts generally favour interpretations that preserve the contract’s validity rather than render it void.

Burden of Proof

In disputes involving conditions subsequent, the burden of proof typically rests on the party seeking to enforce or benefit from the condition. This party must demonstrate that the condition has been triggered and that the specified legal consequences should follow. Evidence supporting the occurrence or non-occurrence of the condition is crucial in such cases.

Public Policy

Conditions subsequent must align with public policy to be enforceable. The courts may invalidate conditions they deem unlawful, immoral, or against the public interest. For example, a condition subsequent that requires an employee to engage in unlawful activities would be unenforceable.

Waiver and Estoppel

Parties to a contract may, either expressly or impliedly, waive a condition subsequent. This waiver can occur through actions that indicate a willingness to continue with the contract despite the condition not being met. Additionally, the doctrine of estoppel can prevent a party from relying on a condition subsequent if their conduct has led the other party to believe that the condition will not be enforced reasonably.

Practical Considerations for Drafting and Managing Conditions Subsequent

To effectively manage conditions subsequent in contracts, it is essential to consider the following practical aspects:

Clarity and Precision

Drafting conditions subsequent with clarity and precision is paramount. The condition should be stated in specific terms, outlining the exact event or action that will trigger the condition and the resulting legal consequences. Avoiding vague language reduces the risk of disputes and ensures that all parties clearly understand their obligations.

Risk Assessment

Before incorporating a condition subsequent into a contract, it is important to assess the associated risks. Consider the likelihood of the condition being triggered and the potential impact on the parties involved. This risk assessment helps in determining whether the condition is appropriate and whether additional safeguards are necessary.

Communication and Documentation

Effective communication between parties is essential when dealing with conditions subsequent. Ensure that all parties are aware of the condition and its implications. Documenting the occurrence or non-occurrence of the condition is equally important, as it provides evidence in case of disputes.

Legal Advice

Seeking legal advice when drafting or negotiating contracts with conditions subsequent is advisable. A solicitor can help ensure that the condition is enforceable, aligns with public policy, and adequately protects the interests of the parties involved.

Case Law

To illustrate the application and implications of conditions subsequent, consider the following case law examples:

Gray v. Gardner (1821)

In this landmark case, the court addressed the issue of conditions subsequent in a commercial contract. The contract included a condition subsequent that allowed the buyer to terminate the agreement if the seller failed to deliver goods within a specified timeframe. The seller argued that unforeseen circumstances had delayed the delivery, but the court upheld the buyer’s right to terminate the contract based on the condition subsequent. This case highlights the importance of adhering to clearly stated conditions and the potential consequences of failing to do so.

Lloyds Bank plc v. Rosset (1991)

In the context of property law, this case involved a dispute over the reversion of property due to a breach of a condition subsequent. The property was conveyed with a condition that it be used for residential purposes. When the grantee used the property for commercial activities, the grantor sought to enforce the condition and reclaim the property. The court ruled in favour of the grantor, emphasising that conditions subsequent must be respected to maintain the integrity of the contractual agreement.

Phoenix Life Assurance Ltd v. Halvanon Insurance Company Ltd (1987)

This case dealt with conditions subsequent in an insurance policy. The policy included a condition subsequent requiring the insured to notify the insurer of any significant changes in risk. When the insured failed to report a significant change in their business operations, the insurer sought to deny coverage for a related claim. The court upheld the insurer’s right to deny coverage, reinforcing the importance of compliance with conditions subsequent in insurance contracts.


Conditions subsequent play a vital role in contract law and real property transactions, providing a mechanism for managing future uncertainties and protecting the interests of the parties involved. Their contingent nature and potential legal consequences make them a powerful tool in contract drafting and negotiation.

To incorporate and manage conditions subsequent effectively, it is essential to draft them clearly, assess associated risks, maintain open communication, and seek legal advice when necessary. Understanding the legal implications and practical considerations of conditions subsequent can help parties navigate complex contractual agreements and ensure that their rights and obligations are adequately protected. As illustrated by case law, the enforcement of conditions subsequent underscores the importance of adhering to contractual terms and the potential ramifications of failing to do so.

Conditions Subsequent FAQ'S

A Condition Subsequent is a condition in a contract or legal agreement that, if it occurs, can terminate or alter the obligations of the parties involved. It differs from a Condition Precedent, which must be fulfilled before the contract becomes effective.

If a specified event or condition occurs after the contract has been executed, the affected party can either terminate the contract or modify its terms as outlined in the agreement. The condition must be explicitly stated in the contract.

An example might be a rental agreement that states the lease will terminate if the property is sold. If the landlord sells the property, this condition subsequent allows the lease to be terminated.

A Condition Precedent must be met before a contract becomes effective or an obligation arises, while a Condition Subsequent occurs after the contract is in effect and can modify or terminate the existing obligations.

Yes, Conditions Subsequent are often used in commercial contracts to manage risk and provide flexibility. They can address future uncertainties and specify outcomes if certain events occur.

Enforcement depends on the clear drafting of the contract. If a Condition Subsequent is triggered, the party seeking to enforce it must demonstrate that the specified event occurred as outlined in the contract.

If a Condition Subsequent is vague or ambiguous, it can lead to disputes and legal challenges. Courts will interpret the condition based on the contract’s overall context and the parties’ intentions, but it’s crucial to draft clear and precise conditions to avoid such issues.

Yes, parties to the contract can agree to waive a Condition Subsequent, either explicitly or implicitly, by their actions or conduct. This waiver must be mutual and clearly documented.

Conditions Subsequent can be included in various types of contracts, including commercial agreements, leases, employment contracts, and more. They are versatile tools for managing future uncertainties in contractual relationships.

When drafting a Condition condition, consider:

  • Clarity and specificity of the condition.
  • Potential impact on the contract and parties involved.
  • Legal enforceability and compliance with applicable laws.
  • Procedures for verification and notification if the condition occurs.
  • Remedies and consequences for non-compliance or disputes.
