Question

Is a one-sided contract legally enforceable?

The other party wrote the entire contract in their favor, does that automatically make it unenforceable?

Answer

No. A contract is not automatically unenforceable simply because it favors one party. Many business agreements and sophisticated commercial contracts allocate more rights, benefits, or responsibilities to one side, and courts generally enforce those provisions. 

However, if the terms are extremely one-sided or the agreement was formed under improper circumstances, questions may arise about whether all or part of the contract can be enforced.

Whether a one-sided contract is enforceable depends on the contract's terms, how it was negotiated, and the laws that apply to the agreement.

When can a one-sided contract become a legal issue?

An imbalance in the contract alone is not usually enough to make it unenforceable. However, certain circumstances may warrant closer review: 

  • Terms that heavily favor one party.
  • Significant limits on one party's rights or remedies.
  • Broad liability or indemnification obligations.
  • Hidden or unclear contract provisions.
  • A large imbalance in bargaining power.
  • Evidence of fraud, duress, or other improper conduct during negotiations.

The overall circumstances surrounding the agreement are often just as important as the wording of the contract.

What factors can affect enforceability?

If a one-sided contract is challenged, several facts may influence the outcome:

  • Whether the parties understood the agreement.
  • The opportunity to review or negotiate the terms.
  • The clarity of the contract language.
  • The business purpose of the challenged provisions.
  • The parties' conduct before and after signing.
  • Applicable laws governing the agreement.

A contract that appears one-sided may still be enforceable, but the facts and surrounding circumstances can make a difference.

What to do next…

  1. Review the contract to identify the terms that concern you most.
  2. Compare the rights and obligations assigned to each party.
  3. Gather records of the negotiations and any proposed changes.
  4. Consider whether the agreement accurately reflects what both parties intended.

What to consider in your specific situation

  • The type of contract and business relationship involved.
  • The specific terms that favor one party.
  • Whether the agreement could be negotiated.
  • The bargaining power of each party.
  • The events leading up to the signing of the contract.
  • Applicable laws governing contract enforceability.

Since every situation is different, consider getting more information through Rocket Copilot or an attorney review to move forward more confidently.
