What is a Bilateral Contract in Real Estate? Definitions and Examples


What is a bilateral contract in real estate? A bilateral contract in real estate refers to an agreement where both parties involved make mutual promises with specific obligations toward each other. Often, this means one party agrees to sell, and the other agrees to buy a property under stipulated terms, ensuring commitments from both ends that are legally binding and enforceable.

Bilateral contracts are foundational in real estate transactions due to their role in clarifying terms, securing commitments, and providing legal safeguards. They represent standard practice in most property dealings, from purchasing and selling to leasing. This intro will quickly guide you through the essentials of what bilateral contracts are, why they’re so important in real estate, and how they operate to enhance transaction security and reliability.

What is a Bilateral Contract in Real Estate?

In the realm of real estate, a bilateral contract is a cornerstone of many transactions, defining the mutual commitments between two parties. Each side agrees to fulfill certain conditions, making these contracts a vital part of property dealings.

Key Characteristics of Bilateral Contracts

A bilateral contract in real estate involves:

  • Mutual Agreement: Both parties in the contract agree to the terms set forth, which are negotiable until mutual satisfaction is achieved.
  • Exchange of Promises: Each party promises to perform certain duties or actions. For instance, one party might agree to sell a property while the other agrees to pay a specified amount.
  • Legal Enforceability: Once both parties sign a bilateral contract, it becomes legally binding. This means that if one party fails to meet their obligations, the other has the right to seek legal remedy.

These characteristics ensure that both parties are clear about their duties and the consequences of not fulfilling them.

Examples of Bilateral Contracts in Real Estate

In real estate, several types of agreements commonly involve bilateral contracts:

  1. Purchase Agreements: Perhaps the most recognized form of bilateral contracts in real estate, these involve a buyer and a seller agreeing on the sale terms of a property. The seller promises to transfer the property’s title to the buyer, and the buyer promises to pay the agreed-upon price.

  2. Lease Agreements: These contracts are between a landlord and a tenant. The landlord agrees to provide the property in a habitable condition, and the tenant agrees to pay rent. Both parties have ongoing obligations throughout the term of the lease.

  3. Sales Contracts: Similar to purchase agreements but often more comprehensive, sales contracts outline the obligations of each party in detail, including payment terms, delivery of property, and conditions for the maintenance or inspection of the property before the final transaction.

Each of these contracts requires a clear understanding of the terms and a commitment to fulfill them, making bilateral agreements fundamental in shaping the landscape of real estate transactions. By ensuring that both parties are legally bound to their promises, these contracts help maintain trust and accountability in property dealings.

Differences Between Bilateral and Unilateral Contracts

Understanding the distinctions between bilateral and unilateral contracts is crucial for anyone involved in real estate transactions. These two types of contracts cater to different scenarios and obligations, making it essential to grasp their nuances.

Understanding Unilateral Contracts

A unilateral contract involves an action that one party promises to pay upon the completion of a specified task by another party. This type of contract is fundamentally a promise for a performance. For example, a real estate developer might offer a reward to anyone who can provide valid information leading to the location of a suitable plot for development. The developer does not require anyone to undertake this task, but if someone completes it, the developer is obligated to pay the reward.

Performance requirement is a key aspect here. The contract is only accepted when the specified task is completed. Until then, the person who might perform the task is not obligated to start or continue the task.

Comparing Bilateral and Unilateral Contracts

When comparing these two types of contracts, the main differences emerge in terms of obligations and acceptance:

  • Obligations: Bilateral contracts involve mutual obligations. Both parties are bound by a promise, such as in a real estate purchase where the buyer promises to pay a certain amount and the seller promises to transfer the property. Unilateral contracts, however, bind only the offeror, who must fulfill the promise once the offeree completes the requested task.

  • Acceptance: In bilateral contracts, acceptance is signified by a return promise, making the contract effective immediately upon agreement. In unilateral contracts, acceptance is typically not expressed through a promise but through performance.

  • Number of parties involved: Bilateral contracts always involve at least two actively obligated parties. Unilateral contracts involve two parties but only one is actively obligated to perform a task until the specific condition is met by the other party.

Examples in real estate for each type:
Bilateral Contract Example: A lease agreement where the landlord promises to maintain the property and the tenant promises to pay rent.
Unilateral Contract Example: A broker offers a commission to any agent who can bring a buyer for a hard-to-sell property. The commitment is only on the part of the broker, who pays upon the agent’s successful performance.

Understanding these differences helps clarify the responsibilities and expectations associated with each type of contract in real estate transactions. This knowledge is vital for ensuring that all parties involved are aware of their rights and obligations, facilitating smoother and more reliable property dealings.

Common Types of Bilateral Contracts in Real Estate

In real estate, bilateral contracts are essential for defining the responsibilities and securing the commitments of the parties involved. These contracts ensure that each party is legally obligated to fulfill their promises, making transactions predictable and enforceable. Below, we explore the common types of bilateral contracts in the real estate sector.

Real Estate Purchase Agreement

A real estate purchase agreement is a prime example of a bilateral contract where mutual promises are key. Here, the buyer and seller have specific obligations:

  • Buyer’s Obligations: The buyer agrees to pay the agreed-upon price by a specified date, often contingent upon securing financing and satisfactory property inspections.
  • Seller’s Obligations: The seller commits to transferring the property title to the buyer, ensuring that the property is in the agreed condition at the time of transfer.

This type of agreement is crucial because it outlines the terms of the sale, including the purchase price, closing date, and any contingencies that may affect the transaction. It’s legally binding once both parties sign, providing a clear roadmap for the transaction.

Lease Agreements

Lease agreements are another common form of bilateral contracts in real estate, involving tenants and landlords:

  • Tenant’s Obligations: Tenants agree to pay rent at specified times and maintain the property according to the lease terms, which might include restrictions like no pets or no alterations without permission.
  • Landlord’s Obligations: Landlords must provide a habitable property and respect the tenant’s rights to privacy and quiet enjoyment. They are also responsible for repairs and maintenance as specified in the lease.

Lease agreements ensure that both the tenant and the landlord understand their duties and rights, which helps prevent disputes and promotes a harmonious rental relationship.

Sales Contracts

In real estate, sales contracts are detailed agreements that specify the terms under which property sales occur. These contracts outline what is being sold, the sale price, and the terms of the transaction, such as closing costs and who bears them. Both the buyer and the seller must fulfill specific roles to complete the property transfer successfully.

Employment Contracts

Real estate agencies and brokerage firms often use bilateral employment contracts to outline the duties and expectations for their agents. These contracts typically include terms about commissions, job duties, and the use of agency resources. Both the employer and the employee are bound to these terms, ensuring clear professional relationships.


Warranties in real estate might include a builder’s warranty on new construction, which promises the buyer that the construction is free from defects for a certain period. Both the builder and the buyer have responsibilities under this agreement: the builder to repair any defects and the buyer to notify the builder in a timely manner.

Each of these contracts plays a crucial role in maintaining order and legality in real estate transactions, ensuring that all parties fulfill their obligations and understand their rights. By clearly defining the responsibilities of each party, bilateral contracts help prevent conflicts and ensure smooth property transactions.

Legal Implications of Bilateral Contracts

What Happens in a Breach of Contract?

When a party involved in a bilateral contract in real estate fails to meet their obligations, this is known as a breach of contract. The consequences can vary but typically include the non-breaching party seeking legal remedies to enforce the contract or to recover damages caused by the breach.

Legal remedies might include:
Damages: Monetary compensation for losses suffered due to the breach.
Specific performance: A court order requiring the breaching party to fulfill their obligations as per the contract terms.

For example, if a seller fails to transfer property ownership after receiving payment, the buyer can seek specific performance to compel the transfer.

How to Resolve Disputes in Bilateral Contracts

Disputes over bilateral contracts in real estate can be resolved in several ways, depending on the severity of the issue and the preferences of the parties involved:

  1. Mediation:
  2. A neutral third party helps both sides reach a voluntary agreement.
  3. This method is less formal and often less costly than litigation.
  4. It allows for creative solutions that courts might not be able to provide.

  5. Arbitration:

  6. Similar to mediation but results in a binding decision made by the arbitrator.
  7. Faster than court proceedings and can be kept confidential.
  8. The parties can agree to arbitrate as part of the contract terms.

  9. Litigation:

  10. Involves taking the dispute to court where a judge (and possibly a jury) will make a decision.
  11. More formal and can be expensive and time-consuming.
  12. Suitable for serious breaches where other methods have failed.

Each method has its advantages and should be chosen based on the specific circumstances of the contract and the nature of the dispute.

By understanding these legal implications and dispute resolution methods, parties in a real estate bilateral contract can better manage their agreements and address any issues that arise, ensuring that their interests are protected and disputes are resolved efficiently.

Frequently Asked Questions about Bilateral Contracts in Real Estate

What makes a real estate contract bilateral?

A real estate contract becomes bilateral when both parties involved make mutual promises and agree to fulfill these promises. For example, in a property sales contract, the seller promises to transfer the property’s title to the buyer, and the buyer promises to pay the agreed price. Both parties have distinct obligations that they must meet to complete the transaction, making the contract bilateral.

How can parties ensure compliance in a bilateral contract?

To ensure compliance in a bilateral contract, both parties should:
Clearly define the terms and obligations: Each party should understand their responsibilities and the conditions they must meet.
Use written contracts: A written contract helps prevent misunderstandings and provides a clear record of what was agreed.
Regular communication: Keep lines of communication open to address any issues or changes that may arise.
Legal review: Have the contract reviewed by a lawyer to ensure that it is legally binding and enforceable.

What are the risks associated with bilateral contracts in real estate?

The risks associated with bilateral contracts in real estate include:
Non-compliance: One party may fail to fulfill their obligations, leading to breaches of contract.
Market changes: Fluctuations in the real estate market can affect property values and the feasibility of the contract terms.
Legal disputes: Disagreements over contract terms or fulfillment may lead to legal action, which can be costly and time-consuming.

Understanding these risks helps both parties prepare better and take preventive measures, such as including contingency clauses in the contract to handle unexpected changes.

By addressing these common questions, parties involved in real estate transactions can navigate bilateral contracts more effectively, ensuring smoother and more secure dealings.
