Imagine you sign a lease to rent an apartment. You promise to pay rent monthly, and the landlord promises to provide you with the living space. Neither of you has fully performed your obligations yet, but you’ve both made commitments to each other. This scenario reflects a common type of contract in business and everyday life: a bilateral executory contract.
If you’ve ever wondered what exactly a bilateral executory contract is, how it differs from other contract types, and why this distinction matters when making agreements, you’re in the right place. This article breaks down foundational concepts in simple terms with examples you can recognize from various industries. It also points you toward practical next steps to understand how these contracts work and how you might draft or manage them effectively.
What Is a Bilateral Executory Contract?
To grasp the idea of a bilateral executory contract, it helps to first understand its parts:
- Bilateral contract: This is a contract in which both parties make mutual promises to each other. Each promises to do something in exchange for the other’s promise.
- Executory contract: This type involves an agreement in which some or all obligations of the parties are yet to be performed. The contract is active and ongoing because the duties agreed upon haven’t been fully completed.
Putting these together, a bilateral executory contract is one where two parties exchange promises, and both still have obligations to fulfill.
Contrast with other contract types:
- Unilateral contract: Only one party makes a promise, which the other party accepts by performing an act (e.g., a reward for finding a lost dog).
- Executed contract: A contract that has been fully performed by all parties; there are no outstanding duties left.
The Four Essential Elements of Bilateral Executory Contracts
- Offer: One party proposes the terms of the contract.
- Acceptance: The other party agrees to those terms unequivocally.
- Consideration: Something of value exchanged between parties.
- Mutual assent and legal capacity: Both parties understand and agree to the contract terms and have the legal ability to enter into the contract.
Each element matters practically for drafting and enforcing contracts because missing or vague elements can cause disputes or render a contract unenforceable.

Real-Life Use Cases of Bilateral Executory Contracts
Bilateral executory contracts appear across industries and contexts. Here are some common examples to illustrate their broad applicability:
- Employment agreements: The employee promises to work, and the employer promises to pay salary. Obligations on both sides continue over time.
- Sales contracts: The buyer promises to pay a price, and the seller promises to deliver goods later.
- Service agreements: One party promises to provide specific services, while the other promises payment upon completion or at milestones.
- Leases: Tenant and landlord exchange promises about occupancy and rent payment.
- Loan agreements: The lender agrees to provide funds, and the borrower agrees to repay with interest on agreed schedules.
These examples show how mutual promises with ongoing performance obligations are common building blocks of business and personal dealings. They highlight why understanding bilateral executory contracts is relevant beyond just legal theory.
Why Does the Distinction Between Executory and Executed Matter?
Knowing whether a contract is executory or executed helps parties understand their current obligations and what remedies might be available if issues arise.
- While the contract remains executory, parties are expected to continue fulfilling duties. For example, a service provider continues work, and the client maintains payment schedules.
- Once all terms are fulfilled, the contract becomes executed, signaling completion.
Challenges arise when one party fails to perform their promise during the executory phase. Remedies might include damages, contract termination, or specific performance requirements. Understanding this lifecycle can guide contract management and risk mitigation.

Common Misconceptions About Bilateral Executory Contracts
It’s easy to get confused about contract terminology. Here are some clarifications to keep concepts clear:
- All bilateral contracts are not necessarily executory. If both parties have completed their promises, the bilateral contract is executed—even though it involved mutual promises.
- Executory can apply to unilateral contracts too, but the key feature is that obligations are still outstanding, no matter the number of promise exchanges.
- Consideration doesn’t always mean money. It means mutual inducement that motivates parties to agree, which can be a service, property, or even a forbearance.
- Mutual promises do not have to be simultaneous. Often contracts recognize time-bound or phased performance schedules.
Knowing these distinctions helps avoid misunderstandings in contract negotiations and drafting.
How Are Bilateral Executory Contracts Drafted? Key Clauses to Consider
When preparing a bilateral executory contract, certain clauses are essential to make the agreement clear, enforceable, and manageable:
- Offer and Acceptance: Clearly define who is promising what, specifying the duties of each party
- Performance Milestones: Specify timelines and performance benchmarks to track ongoing obligations
- Payment Terms: Clarify amounts, schedules, and method of payment
- Remedies for Breach: Define consequences when one party fails to perform (e.g., damages, termination rights)
- Termination Conditions: Describe how and under what conditions parties may exit the contract
- Dispute Resolution: Lay out mechanisms for resolving disagreements (arbitration, mediation, jurisdiction)
- Governing Law: Specify which jurisdiction’s laws apply to interpreting and enforcing the contract
Drafting with these core items helps ensure clarity for ongoing obligations, reduces ambiguity, and aids enforcement if complications arise.
Advanced topics include customizing clauses for specific industries such as software licensing, construction contracts, or employment terms. You can explore more about Contract Drafting Basics here.
How Industry Practices Influence Bilateral Executory Contracts
While the fundamental concepts remain constant, different sectors apply bilateral executory contracts in ways tailored to their unique needs:
- Technology & Software Licensing: May include clauses for licenses, updates, usage limits, and acceptance criteria.
- Real Estate: Common terms involve lease duration, rent escalation, maintenance obligations, and security deposits.
- Healthcare & Services: Often require performance standards, confidentiality, and compliance with regulations.
Understanding these norms helps businesses draft contracts that reflect industry expectations and reduce disputes.
What Happens If a Party Breaches a Bilateral Executory Contract?
Breaches occur when one party fails to meet their promise during the executory phase. Typical consequences include:
- Damages: Monetary compensation covering direct and sometimes indirect losses
- Specific performance: A court may order the breaching party to fulfill obligations
- Termination: The non-breaching party may end the contract
- Renegotiation or remedy period: Some contracts provide “cure” periods before consequences trigger
Knowing potential remedies guides how businesses structure contracts and respond when problems occur. Learn about common remedies for breach to understand how these concepts apply in practice.

Frequently Asked Questions About Bilateral Executory Contracts
Can a contract be both bilateral and unilateral?
No. Bilateral contracts involve mutual promises from both parties, while unilateral contracts involve a promise from one party in exchange for the other’s performance.
When does a bilateral executory contract become executed?
When all parties have completed their obligations and no future performance is pending.
Is consideration always required for a valid bilateral contract?
In most jurisdictions, yes. Consideration is the mutual inducement that makes the contract enforceable, though some modern law approaches focus on mutual assent over strict ‘value’.
What industries commonly use bilateral executory contracts?
Virtually all, including employment, real estate, software licensing, loans, sales, and service agreements.
How does breach remedy differ across industries?
While fundamental remedies like damages or termination apply broadly, some industries have specific regulations or typical practices (e.g., penalties in construction, service level credits in telecom).
Can bilateral executory contracts involve more than two parties?
Yes, but such multi-party contracts require careful drafting to clarify each party’s obligations and risks.
Are bilateral executory contracts enforceable internationally?
Yes, but cross-border contracts often need clear governing law clauses and considerations for jurisdictional differences.
How can technology help manage bilateral executory contracts?
Contract Lifecycle Management (CLM) platforms can track obligations, deadlines, and performance metrics to reduce risk and improve compliance.
