Can I sue someone who owes me money with no written agreement?

Usually yes. An oral loan is a valid contract in most situations, and courts enforce them regularly, especially in small claims. The difficulty is evidentiary: you have to convince the court the loan existed, what the terms were, and that it was a loan rather than a gift. Bank records and the borrower's own messages carry most of that weight.

What evidence proves an oral loan?

A bank or app transfer showing money moving from you to them on a date, text messages or emails where they acknowledge the debt or promise to repay, any partial payments they made, and witnesses who heard the agreement. A memo line that says "loan" helps. The single most powerful item is the borrower saying, in writing, that they owe you.

Does the statute of frauds make my oral loan void?

Not usually for a simple loan, but it can matter. The statute of frauds requires certain contracts to be in writing, most commonly agreements that by their terms cannot be performed within one year. A loan repayable on demand or within a year typically falls outside it, while a multi-year oral repayment plan may be challenged. Rules vary by state.

How long do I have to sue on an oral loan?

Less time than on a written one in many states. Written contracts often carry limitations periods of five or six years or more, while oral contracts are frequently shorter, sometimes two to four years. The clock usually starts when repayment was due or, for a demand loan, when you demanded payment and were refused. Check your own state before assuming you have time.

Can I get them to sign something now?

Yes, and you should. Asking the borrower to sign a promissory note documenting the existing balance does not create a new debt, it memorializes the one that exists. Even a signed written acknowledgment of the amount owed helps enormously, and in most states a written acknowledgment or a partial payment restarts the limitations clock in your favor.

Lending Money With Nothing in Writing: Can You Still Collect?

You sent the money because they needed it and you trusted them. There was no note, no signature, maybe not even a clear repayment date. Months later the topic has gone quiet. The good news is that an oral loan is usually a real contract. The bad news is that proving it, and beating a shorter deadline, is entirely on you.

Your loan is probably valid

Start from the right premise: a spoken agreement to lend and repay money is generally an enforceable contract. Courts hear these cases constantly, particularly in small claims, and they do not throw them out simply because nothing was signed. Validity is rarely the issue. The fight is almost always about two things: proving the money was a loan and not a gift, and proving what the repayment terms were.

The gift problem

This is the defense you should expect: "it was a gift." It comes up constantly between family members and friends, precisely the people who lend without paperwork. Anything that frames the transfer as repayable defeats it. A memo line reading loan, a text saying you will get it back to me next month, a repayment schedule discussed by message, or a single partial payment they already made all cut hard against the gift story.

Evidence that actually carries weight

The transfer record. A bank statement, wire confirmation, or payment-app history showing the money and the date.
Their own words. Texts, emails, or voicemails acknowledging the debt or promising to repay. This is the strongest item you can have.
Partial payments. Even one repayment implies the whole obligation.
Witnesses. Someone who was present when the arrangement was made.
Your contemporaneous notes, which are weaker but better than memory alone.

Where the statute of frauds bites

Certain agreements have to be in writing to be enforced. For loans, the provision that matters most is the one covering contracts that cannot be performed within one year. A loan due on demand or repayable within a year generally sits outside that rule. A multi-year oral repayment plan is more vulnerable to challenge. This varies by state, and it is one of the reasons a long informal loan is riskier than a short one.

The deadline is shorter than you think

Many states give oral contracts a shorter limitations period than written ones. Where a written contract might give you six years, an oral one may give you two to four. The clock generally starts when repayment was due, or for an open-ended loan, when you demanded payment and were refused. This is the quiet risk in informal lending: people wait years to avoid an awkward conversation and let the right to sue expire. See the statute of limitations on old debts.

What to do this month

Gather the paper trail now: transfer records and every message about the money.
Send a friendly written recap. A message that says just confirming, you borrowed $4,000 in March and we agreed you would pay it back by December invites a written reply that becomes your acknowledgment.
Ask them to sign a note. Framing matters: this is not new debt, it is putting the existing one on paper so you both know where you stand.
Make a written demand if it has gone quiet, which also starts the clock cleanly on a demand loan.
Consider small claims if the amount is within your state limit. See small claims court for unpaid notes.

Converting the handshake

Getting a signed promissory note now is the single highest-value move available to you. It fixes the amount, sets a repayment schedule, and in most states a written acknowledgment restarts the limitations clock. It also tends to improve behavior: people repay documented obligations more reliably than vague ones. See converting an IOU into a real promissory note.
