Can You Sue Without a Written Contract?
You lent someone money. You performed work for them. You sold them something. Or maybe you entered into a business deal based on a conversation and a handshake. Now they owe you money and refuse to pay. But there is one problem: nothing was ever formally put in writing. Can you still sue? In California, the answer may be yes. A contract does not always have to be written and signed to be legally enforceable. California courts recognize written, verbal, and even certain implied agreements.
Verbal Agreements Can Be Contracts
A verbal agreement can create an enforceable contract if the basic requirements of a valid contract are present.
Generally, there must be an agreement between the parties, an offer and acceptance, something of value exchanged, parties capable of entering into the agreement, and a lawful purpose.
For example, imagine you lend a friend $10,000 after they agree to repay you within six months. You transfer the money, but six months later they refuse to pay.
The fact that you never signed a formal loan agreement does not necessarily mean you have no case.
In fact, California Courts specifically gives an unpaid loan based on a verbal agreement as an example of a potential breach-of-contract lawsuit.
How Do You Prove an Agreement Without a Contract?
This is where verbal-contract cases can become complicated.
When there is a signed contract, the document itself can establish many of the terms of the agreement. With a verbal agreement, the parties may disagree about what was promised, when payment was due, or even whether an agreement existed at all.
That does not mean there is no evidence.
Evidence of a verbal agreement might include:
- Text messages
- Emails
- Venmo, Zelle, PayPal, or bank transfers
- Checks
- Invoices
- Receipts
- Voicemails
- Witnesses who heard the agreement
- Messages discussing repayment
- Partial payments
- Communications acknowledging the debt
California Courts notes that evidence in a contract dispute can include emails, letters, receipts, bills, other written communications, photographs, witness statements, and other evidence establishing the agreement.
Sometimes the most important evidence comes after the original agreement.
For example, a text saying, “I know I still owe you $8,000. I’ll pay you next month,” could become important evidence when determining whether a debt existed.
What If They Claim the Money Was a Gift?
This is a common problem when money changes hands between friends, relatives, romantic partners, or business associates.
One person says:
“It was a loan.”
The other says:
“It was a gift.”
Without a written agreement, the dispute may come down to the surrounding evidence.
Were payments previously made? Were repayment dates discussed in messages? Did the person refer to the money as a loan? Were there witnesses to the conversation?
The stronger the evidence showing that both parties understood repayment was required, the stronger the potential claim may be.
Are All Verbal Contracts Enforceable?
No.
California law requires certain types of agreements to be in writing. This concept is commonly known as the Statute of Frauds.
For example, certain agreements involving real estate and agreements that, by their terms, cannot be performed within one year generally must be in writing to be enforceable.
There can also be important exceptions and fact-specific issues, so a person should not automatically assume that an unwritten agreement is either enforceable or unenforceable without examining the circumstances.
How Long Do You Have to Sue?
This is particularly important with verbal agreements.
In California, the general statute of limitations for breach of an oral contract is two years from the date the contract was breached. The general deadline for breach of a written contract is four years.
That means waiting too long can potentially eliminate an otherwise valid claim.
Exactly when the clock begins to run can also become a legal issue, particularly when repayment dates were unclear or payments were made over time.
Is It Worth Suing Someone Who Owes You Money?
Having a valid claim and successfully collecting money are two different questions.
Before filing a lawsuit, it can be important to consider:
- How much money is owed?
- What evidence establishes the debt?
- What was the agreed repayment date?
- Does the debtor dispute owing the money?
- Does the debtor have assets or income from which a judgment could potentially be collected?
- Is the claim still within the applicable statute of limitations?
- Would the dispute belong in small claims court or civil court?
California Courts recommends considering not only whether you can prove your claim but also the damages involved, where the case should be filed, applicable deadlines, and the practical issues surrounding a lawsuit.
No Written Contract Does Not Automatically Mean No Case
If someone owes you money and you never signed a formal contract, do not automatically assume that you have no legal options.
A verbal agreement may still be enforceable in California, and texts, emails, payment records, witnesses, and the parties’ conduct can all become important evidence.
The details matter.
If a significant amount of money is involved or the other party is disputing that an agreement ever existed, speaking with a California civil litigation attorney can help you determine whether you have an enforceable claim and what options may be available.
