Can I turn a handshake loan into an enforceable note now?

Yes. The borrower has to sign a written acknowledgment of the existing debt, the new payment terms, and the interest rate going forward. Without the borrower's signature, you have nothing more than what you started with - a verbal IOU that may or may not be provable.

Does signing a new note restart the statute of limitations?

Almost always yes. A new written acknowledgment of the debt resets the clock from the date of signing. This is helpful if your original IOU was close to expiring. It can also be a problem if the borrower was relying on running out the clock - they may refuse to sign for that reason.

Can I add interest now if the original loan had none?

Yes, going forward, with the borrower's consent. You cannot retroactively impose interest the borrower never agreed to. The new note can include both: zero (or low) interest on the principal up to the conversion date, then market or AFR interest from the conversion date forward.

What if the borrower refuses to sign?

You are in the same position as before, with the original IOU evidence (texts, emails, notes, witness testimony) being your only proof. Consider whether to file suit before the statute runs. A demand letter from a lawyer often produces a signature when a friendly request did not.

Should I get a witness or notary on the conversion?

Yes if your state requires it for the loan amount, or if collateral is involved. Even where not required, a notarized conversion note is harder for the borrower to later claim was forged or signed under duress. The cost is low and the protection is real.

Converting an Old IOU Into a Real Promissory Note

A loan to a friend, sibling, or partner that started informally, often years ago, and never got proper paperwork. Recovery is still possible, but the conversion has to be approached carefully. The borrower has to sign, the statute of limitations has to be respected, and the language has to acknowledge what was already there without rewriting history.

Why the original IOU is weak

An undocumented loan or a casual IOU has three problems:

Statute of limitations: oral contracts have a shorter limitation period than written ones in most states (3 to 4 years vs 6 to 15 for written)
Proof: texts, emails, and witness testimony work but require effort and may not survive a credibility contest
Enforcement: small-claims courts and creditors prefer documents to stories

A signed conversion note solves all three.

What a conversion note has to do

The new note has to:

Identify the existing debt (when the original loan was made, the original amount)
Acknowledge the borrower owes that amount minus any payments made to date
Set new repayment terms going forward
Address interest going forward (and, with consent, retroactively)
Be signed by the borrower

Resetting the statute of limitations

A new signed acknowledgment restarts the limitation clock. This is true in most states for written acknowledgments of existing debts. Two practical points:

If your original IOU is close to expiring, get the conversion signed before then. Once the limitation runs, the borrower can raise it as a defense even to a fresh acknowledgment in some states.
If the original limitation has already run, an acknowledgment may revive the debt but it depends on the state. A few states (Mississippi, Wisconsin) require a written acknowledgment to revive a debt past the limitation; many do not allow revival at all.

Interest: going forward only is safest

The cleanest structure:

Original principal less any payments made = current balance
Zero interest on the original balance up to the conversion date
Stated interest rate (at AFR for tax purposes if intra-family) from the conversion date forward

If the borrower agrees to pay interest retroactively for the years since the original loan, you can include a "compromise" amount as added principal. Document that the borrower agreed in writing.

Sample structure of a conversion note

The note typically has these sections:

Recitals: "On [original date], Lender lent Borrower $X. Borrower has paid $Y to date. The current outstanding balance is $Z."
Acknowledgment: "Borrower acknowledges and confirms the debt of $Z owed to Lender."
New terms: principal, interest rate, payment schedule, maturity, late fee, default, security if any
Replacement clause: "This Note replaces and supersedes all prior agreements, oral or written, regarding this debt."
Governing law and execution: state law, signatures, notary if required

The conversation: how to ask

Ask in writing, even if you have already discussed it verbally:

"I want to make this clean for both of us going forward"
"Here is what I show as the balance owed - please confirm or correct"
"Here are the new payment terms I am proposing"
"Take a few days to read it, ask any questions, and let me know"

Avoid framing it as ultimatum or threat. The borrower is more likely to sign a document that feels mutual than one that feels like a setup for collection.

If the borrower refuses or stalls

You have options:

Send a formal demand letter, often through a lawyer
File in small-claims court if the amount is under your state\'s limit
File in superior court for larger amounts
Use the original evidence (texts, bank records of the wire, witness statements)

A lawsuit can sometimes produce a settlement that includes the conversion note plus a payment plan. Filing the suit also stops the statute of limitations clock.

Tax timing: forgiveness during conversion

Some lenders use the conversion as an opportunity to forgive part of the debt as a "compromise." The forgiveness:

Is treated as a gift to the borrower (use annual exclusion - $19,000 per donor per recipient in 2026)
For business creditors, is reported as cancellation of indebtedness income (1099-C if over $600)

For family loans, partial forgiveness during conversion is a common goodwill move. Document it clearly so neither side claims later it was "all" forgiven.
