Types of Contractual Conditions
A condition refers to a commitment or obligation. In legal terms, a condition is a subsidiary obligation incorporated into a principal obligation, namely the contract. It represents a mutual undertaking by which the parties bind themselves to perform or refrain from a specific act within the contract.
Validity and Invalidity of Contractual Conditions Under the Civil Code
Legal Nature of Conditions
A condition constitutes a secondary obligation attached to the principal contract. The relationship between a contract and its conditions is one of principal and accessory.
The existence of a condition depends on the validity of the contract. However, the invalidity or lapse of a condition does not necessarily affect the validity of the contract itself.
Conditions follow the legal status of the contract in all respects, including necessity, permissibility, validity, non-enforceability, and nullity. If the contract is void, the condition is also void.
If the contract is valid, the condition is valid. If the contract is non-enforceable, the condition is likewise non-enforceable.
The parties to a contract may include any condition they deem appropriate, provided that such condition is not among the invalid conditions that are detrimental to the contract.
Types of Conditions
Valid Conditions
Pursuant to Article 234 of the Civil Code, valid conditions are divided into three categories:
- Condition of attribute.
- Condition of result.
- Condition of the act, whether affirmative or negative.
Condition of Attribute
A condition of attribute relates to a specific quality or characteristic of the subject matter of the contract, provided that the subject matter is a tangible external object. Accordingly, two requirements must be met. First, the subject matter of the transaction must be a tangible object. Second, the condition must relate to one of its attributes.
For example, a person may purchase a parcel of land on the condition that it has a width of 50 meters and a length of 100 meters. In this case, the subject matter is a tangible object, and the condition concerns its quantitative attributes. Therefore, a condition of attribute refers to a condition relating to the quality or quantity of the subject matter, such as purchasing a carpet made of silk wool or acquiring an item on the condition that it is antique.
Condition of Result
A condition of result refers to a condition whereby the realization of a specific legal effect is stipulated to occur automatically upon conclusion of the contract. In other words, the parties agree that by entering into the contract, another legal consequence shall simultaneously arise.
An example is a lease agreement that includes an option to acquire ownership, under which the leased property is transferred to the tenant at the end of the lease term.
Condition of the Act
According to Article 234 of the Civil Code, a condition of an act involves an obligation imposed on one of the contracting parties or on a third party to perform or refrain from performing a specific act.
The act may be a legal act, such as entering into another contract, or a material act, such as constructing a building or creating a work of art.
A condition of an act may be either affirmative or negative. An affirmative condition of the act requires the obligated party to perform a specific act. For example, in a contract for the sale of a house, the buyer may undertake to donate a vehicle to the seller free of charge or to construct a three-story building at their own expense.
A negative condition of an act requires the obligated party to refrain from performing a specific act. For instance, in a lease agreement, the tenant may be prohibited from subleasing the property to a third party.
Invalid Conditions
Articles 232 and 233 of the Civil Code distinguish between invalid conditions that do not invalidate the contract and invalid conditions that render the contract void. Accordingly, conditions are divided into two main categories:
- Invalid conditions that do not invalidate the contract.
- Invalid conditions that invalidate the contract.
Invalid Conditions That Do Not Invalidate the Contract
Pursuant to Article 232 of the Civil Code, the following conditions are invalid but do not invalidate the contract:
- A condition that is impossible to perform.
- A condition that lacks rational benefit or utility.
- An unlawful condition.
Impossible Conditions
The purpose of including a condition in a contract is to bring about its realization. If performance of the condition is impossible, whether it concerns the delivery of property or the performance of an act, the intended benefit to the beneficiary cannot be achieved, rendering the condition invalid.
Such a condition is treated as nonexistent, meaning that the parties have no genuine intent to perform it. As a result, its invalidity does not affect the contract. For example, if in the sale of a house the buyer stipulates that the seller must transfer a parrot free of charge within two days, but it is later discovered that the parrot had escaped before the contract was signed, the buyer may be entitled to damages. Another example is a construction contract requiring completion of a twenty-story building within one month.
Conditions Without Rational Benefit
The benefit referred to must be rational and reasonable. A condition lacking such benefit is considered meaningless by reasonable persons, and the law regards its performance as legally ineffective. Therefore, such a condition is invalid for lacking purpose and effect.
Unlawful Conditions
An unlawful condition contravenes applicable statutory laws. Since the performance of an unlawful act is legally impermissible, the law does not support enforcing such a condition. A condition lacking legal support is not recognized as a legal right and is legally ineffective and void.
Invalid Conditions That Invalidate the Contract
Conditions Contrary to the Essence of the Contract
Every contract has inherent legal effects. A condition that contradicts the essential nature of the contract is invalid and also renders the contract void. The essential effect of a contract constitutes its core substance, and removal of this effect eliminates the existence of the contract itself.
Just as it is impossible to request salt that is not salty, it is equally impossible to recognize a contract while denying its essential legal effect. The essential effect of a contract is inseparable from the contract itself.
Ambiguous Conditions Causing Uncertainty in the Subject Matter
If a condition incorporated into a contract creates uncertainty regarding the subject matter or the consideration, one of the essential requirements for the contract’s validity is undermined, rendering it invalid.
Since the principal contract becomes void, there remains no basis for the survival of the condition, which is merely an accessory obligation.
Frequently Asked Questions About Types of Contractual Conditions
A condition is a subsidiary obligation incorporated into a contract, the validity and effect of which depend on the principal contract.
Under Article 234 of the Civil Code, valid conditions include conditions of attribute, conditions of result, and conditions of act.
It is a condition relating to a specific quality or quantity of the subject matter of the contract.
It is a condition that stipulates the automatic effect of the contract upon its conclusion.
It is an obligation to perform or refrain from performing a specific act, which may be affirmative or negative.
Conditions that are impossible, lack rational benefit, or are unlawful are invalid but do not invalidate the contract.
Conditions contrary to the essence of the contract or conditions that create uncertainty regarding the subject matter render both the condition and the contract void.
No. Only conditions that invalidate the essence of the contract or cause fundamental uncertainty lead to invalidity of the contract. Otherwise, the contract remains valid. What is a condition in a contract?

Does the invalidity of a condition always affect the contract?
If the parties forget to include an important condition in the contract, can they add it later?
Yes. In many cases, the parties may amend their agreement by mutual consent and add new contractual conditions. The amendment should be documented properly to avoid future disputes and to ensure clarity regarding each party’s obligations.
Can a condition in a contract be valid even if it only benefits one of the parties?
Yes, provided the condition is lawful and agreed upon by both parties. Contractual terms do not always have to provide identical benefits, but they should comply with the applicable legal framework and the parties’ mutual agreement.
What happens if one of the agreed conditions becomes impossible to perform after the contract is signed?
The legal consequences depend on the nature of the condition, the reason performance became impossible, and the governing law. In some situations, the contract may continue, while in others the affected provision or even the agreement itself may require further legal consideration.
Can verbal conditions agreed before signing become part of the contract even if they’re not written down?
That depends on the contract, the governing law, and the available evidence. To reduce uncertainty, important conditions should ideally be included in the written agreement rather than relying on prior verbal discussions.
Can a court refuse to enforce a contractual condition if it’s considered unfair?
Potentially, yes. A contractual condition that conflicts with mandatory legal rules or public policy may not be enforceable. The outcome always depends on the specific wording of the agreement and the applicable law.
Is there any limit to the number of conditions the parties can include in a contract?
Generally, the parties are free to include as many lawful conditions as they consider appropriate. However, each provision should be clear, practical, and consistent with mandatory legal requirements.
Can a condition require one party to do something after the contract has already been completed?
Yes. Certain contractual obligations, such as confidentiality, non-disclosure, or post-completion cooperation, may continue even after the main obligations under the contract have been fulfilled, depending on the parties’ agreement.
If a contractual condition is found to be invalid, does that automatically make the whole contract invalid?
Not necessarily. In many situations, an invalid condition does not affect the remainder of the contract, particularly if the agreement can still operate without that provision. The answer depends on the contract and the applicable legal rules.
Can the parties waive one of the contractual conditions later if they both agree?
Yes. Subject to the terms of the agreement and the applicable law, parties may agree to waive or modify certain contractual conditions. It is generally advisable to record such changes in writing to avoid future misunderstandings.
What’s the most common drafting mistake you see regarding contractual conditions?
One common issue is using vague or ambiguous language that leaves room for different interpretations. Clearly defining each condition, the parties’ responsibilities, and the consequences of non-compliance can significantly reduce the risk of future disputes.
