Is a promissory note legally binding in Tennessee?

Yes. A promissory note is legally binding in Tennessee when the borrower signs a written promise to repay a set amount on stated terms. Tennessee gives a lender ten years to sue on a demand note, and the interest a note can carry is tied to a formula rate the state announces every week.

Tennessee doesn't require magic words. A court wants a clear record of the deal: the lender's and borrower's names, the principal, the interest rate, how and when repayment happens, and the borrower's signature. Write the rate as a number in the note itself. That way, nobody can argue later about what was agreed. If the borrower pledges a house or a car, use a secured promissory note and a separate document that creates the lien.

A few additions make a Tennessee note easier to enforce. Date it. Name Tennessee as the governing law. Say whether the borrower can prepay without a penalty. Spell out what counts as a default and whether you can call the whole balance due after one. Each of those terms answers a question a judge would otherwise have to guess at.

How long a Tennessee lender has to sue

The deadline depends on what kind of paper you hold. Tenn. Code Ann. 28-3-109(c) says actions "on demand notes shall be commenced within ten (10) years after the cause of action accrued," as the Tennessee Court of Appeals quoted it in a family loan case from Bradley County. A demand note is one you can call due whenever you choose.

Debts with no note behind them get less time. In that same case, the court repeated its earlier holding that "the six-year statute of limitation applies to debts that are not evinced by a note." The court also explained that an obligation which "neither explicitly states that it is due on demand nor sets a specified date for repayment" is still a demand obligation, and the claim accrues at once, when the money is received. A handshake loan with no due date can start its clock the day you hand over the cash.

Promises to pay can keep a debt alive. The court found that a borrower's repeated promises tolled the six-year period, citing a Tennessee Supreme Court rule that a promise to pay serves to "keep the debt alive for the statutory period from that time." Save every text, email, or letter in which the borrower acknowledges the debt. If you hold a demand note, make the demand in writing and keep proof of when it went out, such as a certified mail receipt or a saved email. State the balance, the date you expect payment, and where to send it. A dated demand gives you a clean record of when you asked, and it tells the borrower the informal phase is over.

What interest rate Tennessee allows

Tennessee ties its general interest ceiling to a moving target. The Tennessee Department of Financial Institutions (TDFI) announces a maximum effective formula rate every week, and it describes that rate as "a ceiling of 4 percent over the weekly average prime loan rate." The department says "Chapter 464, Public Acts of 1983" requires the weekly announcement, and each rate stays in effect until the average prime loan rate changes.

Here's how the math works with a few sample prime rates. On a $15,000 note repaid in one lump sum after a year, the maximum simple interest moves with the formula:

Before you sign, check the TDFI announcement for that week and pick a rate comfortably under it. Our usury limit checker runs the comparison for you. Then write the rate into the note as a fixed number, with a line showing you checked. A clause like this works:

Interest. The unpaid principal accrues simple interest at [rate] percent per year. The parties confirm that this rate is below the maximum effective formula rate announced by the Tennessee Department of Financial Institutions for the week in which this Note is signed, and a copy of that announcement is attached.

A fixed number is safer than a floating one. A rate written as "the formula rate" moves every week, and nobody wants to rebuild a payment schedule that often. Home loans follow a separate ceiling, which TDFI sets at "four (4) percentage points above the average prime offer rate (APOR)" for a thirty-year fixed loan.

Interest changes again if you end up in court and win. The Tennessee Administrative Office of the Courts (AOC) says any judgment entered carries interest "two percent below the formula rate" published by TDFI. With a 10.5 percent formula rate, a judgment would carry 8.5 percent.

Keep the original signed note somewhere safe. A copy works for everyday reference, but in court the person holding the original is best placed to prove the right to collect. Store it with your payment log, the bank record showing the loan went out, and any messages where the borrower mentions the debt.

Notarization is a separate question. The borrower's signature creates the obligation, and none of the Tennessee rules discussed here call for a notary. A notary's acknowledgment still helps if the borrower later denies signing. If a deed of trust secures the note, ask the county register of deeds what that document needs before you record it.
