What to Do If Someone Breaks a Contract

Short Answer

If someone breaks a contract, the first step is to stay organized and review the agreement carefully.

You should try to understand what was promised, what went wrong, what evidence you have, how much money you lost, and what options may be available. Depending on the situation, you may be able to negotiate, send a demand letter, use mediation, file in small claims court, start a civil lawsuit, or follow an arbitration process required by the contract.

In simple terms:

If someone breaks a contract, review the contract, collect evidence, calculate your losses, try to resolve the dispute, and understand your legal options before taking action.

What Does It Mean to Break a Contract?

Breaking a contract is often called breach of contract.

A breach of contract happens when one party fails to do something required by the agreement.

Examples may include:

• Failing to pay money owed
• Not delivering goods
• Delivering defective goods
• Not completing work
• Missing an important deadline
• Providing poor-quality work
• Canceling without legal reason
• Refusing to return property
• Violating confidentiality terms
• Failing to follow lease terms
• Not performing promised services

Not every disagreement is automatically a breach of contract. Sometimes the contract terms are unclear. Sometimes one side may have a valid excuse. Sometimes both sides may disagree about what was actually promised.

That is why the first step is to understand the agreement.

Step 1: Read the Contract Carefully

Before taking action, read the contract from beginning to end.

Look for:

• Names of the parties
• Description of the work, goods, or services
• Payment terms
• Deadlines
• Delivery requirements
• Cancellation terms
• Refund policy
• Warranty language
• Notice requirements
• Mediation or arbitration clauses
• Attorney fee clauses
• Limitation of liability clauses
• Governing law
• Court or venue clauses

Sometimes the contract explains exactly what must happen if one side does not perform.

For example, the contract may require written notice and a chance to fix the problem before a lawsuit can be filed.

If you skip this step, you may accidentally violate the contract yourself.

Step 2: Identify the Exact Promise That Was Broken

Try to identify the specific part of the contract that was not followed.

Instead of saying:

• “They broke the contract.”

Be specific:

“The contractor agreed to finish the bathroom remodel by May 1, but the work was still incomplete on June 15.”

Or:

“The customer agreed to pay $2,500 within 10 days after delivery, but no payment was made.”

The more specific you are, the easier it is to explain the dispute.

Ask yourself:

What did the other side promise?

Where is that promise stated?

When was performance due?

What exactly did they fail to do?

Did they fail completely or only partly?

Did they give a reason?

Did I perform my own obligations?

A clear explanation helps with negotiation, mediation, small claims court, or a civil lawsuit.

Step 3: Check Whether You Performed Your Own Obligations

In many contract disputes, each side has obligations.

Before claiming that the other side breached the contract, ask whether you did what you were supposed to do.

For example:

Did you pay on time?

Did you provide access to the property?

Did you deliver required information?

Did you approve work when required?

Did you meet your own deadline?

Did you follow the notice procedure?

Did you avoid interfering with the other side’s performance?

If you did not perform your own obligations, the other side may raise that as a defense.

This does not always mean you lose, but it may affect the strength of your claim.

Step 4: Gather Evidence

Evidence is critical in a contract dispute.

Useful evidence may include:

• The contract
• Emails
• Text messages
• Invoices
• Receipts
• Proof of payment
• Bank records
• Photos
• Videos
• Work orders
• Purchase orders
• Delivery records
• Repair estimates
• Inspection reports
• Witness information
• Call notes
• Project notes
• Demand letters
• Prior settlement offers

Do not rely only on memory. Contracts are usually easier to prove when records are organized.

Create a folder with all documents and arrange them in date order.

Step 5: Make a Timeline

A timeline helps organize the facts.

Include:

• Date the agreement was made
• Date payment was made
• Date work started
• Important communications
• Missed deadlines
• Complaints
• Attempts to resolve the issue
• Dates of partial performance
• Date the breach happened
• Any later promises or excuses

Example:

March 1: Signed contract for fence repair. March 3: Paid $1,500 deposit. March 10: Contractor began work. March 15: Contractor stopped showing up. March 20: Sent text asking for update. March 25: Contractor promised to return by March 28. April 1: Contractor still had not returned. April 5: Sent written demand letter.

A simple timeline can make the dispute much easier to understand.

Step 6: Calculate Your Damages

Damages are the losses caused by the breach.

In a contract dispute, damages may include:

• Money paid for work not completed
• Cost to repair defective work
• Cost to hire someone else
• Unpaid invoices
• Lost deposits
• Extra delivery costs
• Replacement costs
• Late fees
• Lost profits in some business cases
• Other losses allowed by law or contract

You should be able to explain how you calculated the amount.

Example:

If you paid a contractor $3,000 and must pay another contractor $4,500 to fix and complete the work, your damages may include the extra cost caused by the breach.

However, damages can be complicated. Some contracts limit damages. Some losses may be too remote or speculative. Some damages may not be available unless they were foreseeable or allowed by law.

Step 7: Try to Reduce Further Losses

In many contract cases, the harmed party may need to take reasonable steps to reduce additional losses. This is often called mitigation of damages.

For example:

If a contractor clearly refuses to finish a project, the homeowner may need to take reasonable steps to prevent the damage from getting worse instead of doing nothing for months and letting the loss increase unnecessarily.

Mitigation does not mean you must accept unfair treatment. It means you should act reasonably to avoid avoidable losses.

Examples of mitigation may include:

• Hiring a replacement contractor
• Covering exposed property
• Stopping use of defective equipment
• Finding another buyer or seller
• Re-renting a property where allowed
• Keeping damaged property from getting worse
• Responding to problems promptly

Keep records of what you did to reduce the loss.

Step 8: Communicate Clearly and Professionally

Before filing a claim, it may help to communicate with the other side.

Keep the message short, factual, and professional.

Avoid insults, threats, or emotional language.

A simple message may say:

“According to our agreement dated March 1, 2026, the fence repair was supposed to be completed by March 15. The work remains unfinished. Please let me know by Friday whether you will complete the work or refund the deposit.”

This type of message creates a written record and may lead to a solution.

Whenever possible, communicate in writing so you can save the record.

Step 9: Send a Demand Letter

If informal communication does not work, you may consider sending a demand letter.

A demand letter is a written request asking the other side to fix the problem, pay money, complete work, refund payment, or otherwise resolve the dispute.

A demand letter may include:

• Date of the agreement
• Names of the parties
• What the contract required
• What the other side failed to do
• Evidence supporting your position
• Amount requested
• Deadline to respond
• Possible next steps if not resolved

A demand letter should be clear and professional.

Example:

“I am requesting a refund of $1,500 by June 15, 2026. If this matter is not resolved by that date, I may consider available legal options.”

Do not exaggerate. Do not make false statements. Do not threaten anything illegal.

Step 10: Check the Contract for Mediation or Arbitration

Before filing a lawsuit, check whether the contract requires mediation or arbitration.

Some contracts say the parties must try mediation before suing.

Some contracts require binding arbitration instead of court.

An arbitration clause may affect:

• Where the dispute is handled
• Who decides the dispute
• Whether you can go to court
• Whether you can have a jury trial
• What fees apply
• Whether appeal rights are limited

If your contract has a dispute resolution clause, read it carefully before taking action.

Step 11: Consider Settlement

Many contract disputes settle without trial.

A settlement may include:

• Payment of money
• Payment plan
• Refund
• Completion of work
• Repair or replacement
• Return of property
• Cancellation of contract
• Revised agreement
• Release of claims
• Dismissal of lawsuit

Settlement can save time, money, and stress. It also gives the parties more control over the outcome.

However, settlement agreements can affect legal rights. Be careful before signing a release or agreeing to dismiss a claim.

Step 12: Consider Small Claims Court

If the amount is within your state’s small claims limit, small claims court may be an option.

Small claims court is often used for:

• Unpaid invoices
• Security deposits
• Poor workmanship
• Personal loans
• Refund disputes
• Small service agreements
• Minor property damage
• Breach of contract claims

Small claims court is usually less formal than regular civil court, but rules still matter.

You may need to:

• File the correct form
• Pay a filing fee
• Serve the defendant properly
• Bring evidence
• Attend a hearing
• Explain your damages
• Collect the judgment if you win

Small claims limits, procedures, and attorney rules vary by state.

Step 13: Consider a Civil Lawsuit

If the dispute involves more money, complex facts, business issues, real estate, employment, construction, or important legal rights, a regular civil lawsuit may be necessary.

A civil lawsuit may involve:

• Complaint
• Service of process
• Answer
• Motions
• Discovery
• Mediation
• Settlement
• Trial
• Judgment
• Appeal

Civil litigation can be time-consuming and expensive. It may be wise to speak with a lawyer before filing.

What Remedies May Be Available?

A remedy is what you ask for when someone breaks a contract.

Possible remedies may include:

Money damages

Money damages are the most common remedy in contract cases. They are intended to compensate the harmed party for losses caused by the breach.

Expectation damages

Expectation damages try to put the non-breaching party in the position they would have been in if the contract had been performed.

Reliance damages

Reliance damages may compensate a party for costs spent because they relied on the agreement.

Consequential damages

Consequential damages are losses that result from the breach, beyond the direct failure to perform. These may be limited by the contract or law.

Specific performance

Specific performance is a court order requiring a party to perform the contract. This remedy is less common and often used when money is not enough, such as certain real estate disputes or unique property.

Injunction

An injunction may order a party to do something or stop doing something. This is usually available only in certain situations.

Rescission

Rescission means canceling the contract and trying to return the parties to their earlier positions.

The available remedy depends on the contract, facts, law, and court.

What If the Other Side Says They Will Break the Contract?

Sometimes one party says or clearly shows they will not perform before the performance deadline. This may be called anticipatory breach or anticipatory repudiation.

Example:

A supplier agrees to deliver materials on July 1. On June 10, the supplier says, “We will not deliver anything.”

This can create legal options for the other party, but the rules can be complex.

If a party clearly refuses to perform before the deadline, it may be important to act carefully, preserve evidence, reduce losses, and consider legal advice.

What If the Contract Was Verbal?

A verbal agreement may sometimes be legally binding, but it is usually harder to prove than a written contract.

If the contract was verbal, evidence may include:

• Text messages
• Emails
• Payment records
• Witnesses
• Partial performance
• Invoices
• Receipts
• Call notes
• Photos
• Business records

Some types of contracts must be in writing to be enforceable. These rules vary by state and type of agreement.

What If You Also Broke the Contract?

Sometimes both sides claim the other side breached the contract.

Example:

A contractor claims the homeowner failed to make a payment. The homeowner claims the contractor did defective work.

In this situation, both sides may have claims and defenses.

The outcome may depend on:

• Who breached first
• Whether the breach was material
• Whether performance was excused
• Whether damages were caused
• What the contract says
• What evidence exists

These disputes can become complicated quickly.

Common Mistakes People Make

Mistake #1: Acting before reading the contract

The contract may contain notice requirements, deadlines, mediation clauses, arbitration clauses, or limits on remedies.

Mistake #2: Not saving evidence

Text messages, emails, receipts, invoices, photos, and payment records can be critical.

Mistake #3: Waiting too long

Contract claims have deadlines. These deadlines vary by state and type of contract.

Mistake #4: Not calculating damages clearly

If you ask for money, you should be able to explain the amount.

Mistake #5: Ignoring mitigation

You may need to take reasonable steps to avoid making the loss worse.

Mistake #6: Making emotional threats

Angry messages can hurt credibility. Keep communication professional.

Mistake #7: Signing a settlement too quickly

A release may give up important rights. Read settlement terms carefully.

Mistake #8: Filing in the wrong place

The contract may require a specific court, county, state, mediation process, or arbitration forum.
