Can I Sue on a Loan If I Don’t Have It in Writing?

This is one of the most common questions people bring to us. You loaned money to a friend, a relative, or a business associate, assumed it would be repaid as agreed, and never put anything in writing. Now you are not getting paid back, and you want to know whether you can do anything about it.

The realistic answer is maybe, and more often than people expect. Texas law does not require a written contract for a loan to be enforceable. A loan can be made by spoken agreement, by an exchange of texts or emails, or by some mix of conduct and communication. And the legal claims you can bring do not all depend on a signed loan agreement.

This page lays out the framework. It is not a substitute for advice on your specific matter, but it is how we typically analyze unwritten-loan cases.

The Causes of Action

In Texas, a creditor pursuing an unwritten loan usually has three possible claims, sometimes pleaded in the alternative.

Breach of Oral Contract

Texas allows breach-of-oral-contract claims. The elements are essentially the same as a written contract (offer, acceptance, consideration, definite terms, and breach), but you prove the agreement and its terms through testimony, conduct, and whatever communications exist (text messages, emails, witnesses) instead of a single signed document.

For a loan, the elements usually look like this:

• You offered to provide money
• The borrower accepted and agreed to repay
• The loan was made (that is the consideration)
• The repayment terms were definite enough to enforce (amount, time, interest if any)
• The borrower failed to repay as agreed

The four-year limitations period under Texas Civil Practice & Remedies Code § 16.051 generally applies. The clock usually starts when the debt comes due, which turns on the loan’s terms: at an agreed repayment date if there was one, or at the time of demand for a loan payable on demand.

Money Had and Received

This common-law claim lets a creditor recover money the defendant received that, in equity and good conscience, the defendant ought to return. It is broader than breach of contract because it does not require a contract at all, only that the defendant received money belonging to you and is unjustly holding onto it.

It is useful when:

• The contract terms were murky but the money clearly changed hands
• The borrower disputes that there was a “loan” but cannot explain why the money was kept
• The transfer was for a specific purpose the borrower failed to honor
• The relationship was informal but the transfer of money is documented

Courts have applied both two-year and four-year periods to money had and received, depending on how the claim is characterized, so we assess its limitations on the specific facts and lead with the contract claim’s four-year period.

Unjust Enrichment

This is related to money had and received but framed in equity: the defendant was enriched at your expense under circumstances that make keeping the benefit unjust.

It is useful when:

• The transaction does not fit neatly into a contract or money-had-and-received frame
• The borrower received goods, services, or other value, not just money
• Your loss and the defendant’s gain are clearly connected

Texas courts have generally applied a two-year limitations period to unjust enrichment, though the point is not uniformly settled. Because it can be the shortest of the three windows, we don’t rely on it standing alone.

We usually plead in the alternative: breach of contract as the primary claim, money had and received as the alternative, and unjust enrichment as the equitable backup. The court decides which claim, or combination, supports recovery.

The Evidence That Supports Unwritten-Loan Claims

How strong an unwritten-loan case is comes down to the evidence. The evidence we most often rely on:

Bank records, wire records, electronic transfer records. Records showing the money moved from you to the borrower, with a date, an amount, and a recipient. This establishes the transfer itself.

Text messages. Texts where the borrower acknowledges the loan, references the obligation, promises to repay, asks for more time, or otherwise treats the money as a debt. Texts are admissible under the same rules as any other written communication.

Emails. Emails discussing the amount, the repayment terms, or the borrower’s circumstances. The most useful are often the ones where the borrower mentions the obligation in passing, because those tend to carry more weight than emails that were specifically negotiating the loan.

Voicemails. Voicemails where the borrower acknowledges the obligation, even briefly.

Witness testimony. People who heard the loan discussed when it was made, or who heard the borrower acknowledge it later.

Partial payments. In many unwritten-loan cases this is the single strongest piece of evidence. A partial payment is hard to explain as anything other than acknowledgment of a debt, and a pattern of payments, even small ones, can essentially establish both the loan and the borrower’s recognition of it.

The borrower’s own accounting records. If the borrower’s books list the obligation as a payable, that listing is evidence. Discovery can sometimes surface those records.

Tax records. If the borrower deducted the loan as an expense or otherwise treated it as a debt for tax purposes, that treatment is evidence. It is less commonly available but sometimes discoverable.

Other contemporaneous documents. Anything from the time of the loan or during the relationship that references it: receipts, business documents, personal correspondence.

We review the available evidence at intake and tell you candidly whether the matter is provable.

The Common Defenses on Unwritten-Loan Claims

Borrowers in these matters usually raise one or more of the following.

“It was a gift, not a loan.” The most common defense. The borrower says the money came with no expectation of repayment. We beat it with evidence that the money was a loan: repayment discussions, partial payments, contemporaneous statements about repayment, the surrounding circumstances, and often the absence of any sign the money was a gift, such as a birthday card, a holiday occasion, or any charitable framing.

“It was an investment, not a loan.” The borrower says the money was an investment in a business or venture, with no duty to repay if it failed. This is fact-specific. Evidence of agreed repayment regardless of how the venture turned out, a fixed amount and timing, and the absence of any equity-style upside for you all cut against it.

Statute of limitations. The borrower argues the limitations period has run. We track the limitations clock closely, and for loans without a fixed due date the clock often started later than the borrower claims, usually when you first demanded payment.

No definite terms. The borrower argues the loan was too indefinite to enforce, with no agreed amount, timing, or interest. We answer this with the evidence of the actual transaction. Most loans have at least the principal amount fixed by the transfer itself, and the timing is often inferable from the relationship and what you expected.

Statute of frauds. Some contract types must be in writing under Texas Business & Commerce Code § 26.01, the statute of frauds. Personal loans between individuals usually fall outside it, but specific transaction types might not, so we evaluate this matter by matter.

“I already paid you back.” The borrower claims a partial or full repayment that you dispute. This becomes a factual fight, settled with bank records, communications, and other evidence of what was actually paid.

When We Tell You It Won’t Work

We are candid when an unwritten-loan matter is not viable. The situations where we usually advise against pursuit:

No transfer evidence. If you cannot show that money actually moved from you to the borrower, the matter has no foundation. Undocumented cash transfers are especially hard.

Strong gift indicators. If the surrounding circumstances point strongly to a gift (an occasion-based transfer, money to a relative during a milestone event, contemporaneous statements framing it as a gift), your claim faces real trouble.

Statute of limitations clearly run. If the limitations period has clearly run with no available tolling argument, the matter is not viable.

Borrower has nothing. If the matter is provable but the borrower has no current assets and no realistic prospects, the cost of pursuit is not worth the realistic recovery.

Documentation missing on both sides. If neither your records nor the borrower’s communications support the claim, it usually cannot be proved.

When we see these patterns, we say so plainly, and you can decide what to do with that.

The Cost-Benefit on Unwritten-Loan Matters

Here is a practical point worth knowing. Under Texas Civil Practice & Remedies Code Chapter 38, attorney’s fees are recoverable on certain claims, including breach of an oral or written contract for goods, services, or money loaned. For unwritten-loan matters that fit Chapter 38, winning means recovering fees on top of principal and interest, which changes the cost-benefit math considerably.

For loans in the $10,000 to $50,000 range, the most common range for the personal loans we see, the combination of recoverable principal, interest, and attorney’s fees often justifies pursuit even after the cost of litigation.

For very small loans, under a few thousand dollars, the math is less favorable, and we will tell you honestly when a small unwritten-loan matter is not economic to pursue.
