In Missouri, the deadline to sue you on a debt depends on the kind of debt. Under Missouri Revised Statutes (RSMo) Section 516.110, a creditor generally has 10 years to sue on a written contract or other written promise to pay money, including most promissory notes. Under RSMo Section 516.120, the deadline drops to 5 years for open accounts and for contracts that are not in writing. These are some of the longer limitations periods in the country, so Missouri consumers should not assume an old debt is automatically too stale to sue on. Once the correct period runs out, though, the expired statute of limitations becomes a complete legal defense you can raise to defeat the lawsuit.
Missouri's Statute of Limitations by Debt Type
A "statute of limitations" is the legal time limit for filing a lawsuit. After it expires, the debt does not vanish, but a court can no longer force you to pay it if you properly raise the defense. In Missouri, the period that applies turns on how the debt is legally classified:
Written contracts and written promises to pay money – 10 years (RSMo 516.110). This covers an action "upon any writing... for the payment of money or property." A signed loan agreement and most promissory notes fall here.
Promissory notes – generally 10 years. Because a promissory note is a written promise to pay a fixed sum, Missouri courts typically treat it under the 10-year rule.
Open accounts and oral or implied contracts – 5 years (RSMo 516.120). An "open account" is a running balance like a revolving store account. Oral agreements and other obligations not covered by the 10-year statute fall under the 5-year period.
What About Credit Card Debt?
Credit card debt is the gray area in Missouri, and it matters a great deal because the difference is 5 years versus 10 years. Some courts and collectors argue that a credit card account is governed by a written cardholder agreement, which would point to the 10-year written-contract statute. Others treat a revolving credit card balance as an open account subject to the 5-year statute. Because the outcome can depend on the specific facts, the documents a collector can actually produce, and how a particular Missouri court has ruled, you should not assume your card debt is time-barred without confirming which period applies to your situation. This is an area where guidance from a Missouri-licensed attorney or a legal aid office is especially valuable. Do not rely on a collector's characterization of the deadline.
When Does the Clock Start?
In Missouri the limitations period generally begins to run when the cause of action "accrues" – that is, when the creditor first has the right to sue. For most consumer debts, that is the date you defaulted: typically the date of your last payment or the date a required payment was missed and never cured. It is not the date you opened the account or the date the debt was sold to a collector.
Selling or transferring a debt does not reset this clock. When a charged-off account is bought by a debt buyer, the new owner steps into the original creditor's shoes and inherits the same accrual date and the same deadline. A debt buyer cannot extend the limitations period simply by purchasing the account.
The Critical Trap: How the Clock Can Restart
This is the single most important rule for Missouri consumers to understand, because a small action can quietly hand a creditor years of new time to sue. In Missouri:
A voluntary partial payment can restart the clock. Missouri courts have long held that a part payment on a debt can revive the obligation and begin a fresh limitations period from the date of that payment. Even a small "good faith" payment to a collector can do this.
A written acknowledgment or new promise can restart the clock. Under RSMo Section 516.320, an acknowledgment or new promise to pay must be in writing and signed by the person to be charged in order to revive a contract debt. So a signed letter, a written payment agreement, or other written admission that you owe the debt can reset the period.
The practical danger is real. Collectors sometimes pursue debts that are close to expiring and try to coax even a single payment or a written admission out of you, because that one act can extend the time they have to sue. Before you make any payment, sign any document, or admit in writing that an old debt is yours, find out whether the limitations period has already run. If it has, restarting it can take away a defense you would otherwise have.

Be careful what you say in writing, including emails and online chat with a collector. While Missouri requires a written, signed acknowledgment to revive a contract debt, the safest course with an old debt is to avoid both partial payments and written admissions until you have confirmed the deadline.
An Expired Statute of Limitations Is a Defense You Must Raise
Here is the part that surprises many people: even when the statute of limitations has clearly expired, a creditor or debt buyer can still file a lawsuit, and Missouri courts will not throw it out automatically. The expired deadline is an affirmative defense. That means you must raise it – in writing, in your formal court response (your "answer") – or you can lose the protection entirely.
If you ignore a debt lawsuit and fail to show up or respond, the court can enter a default judgment against you even on a debt that was decades too old to sue on. A default judgment can lead to wage garnishment and bank account levies. So the most important steps are: (1) never ignore a summons; (2) respond by the deadline stated in the papers; and (3) specifically plead the statute of limitations if the debt is time-barred. Many people in this situation benefit from talking to a consumer attorney or Missouri legal aid before filing their answer.
How Missouri Compares to Federal Law
Federal law provides a separate layer of protection that works alongside Missouri's deadlines:
Fair Debt Collection Practices Act (FDCPA). This federal law governs third-party debt collectors nationwide. It is generally illegal for a collector to sue or threaten to sue you on a debt they know is past the statute of limitations. If a collector files a time-barred lawsuit, you may have an FDCPA claim against them.
Fair Credit Reporting Act (FCRA). Separately from the right to sue, most negative debts can stay on your credit report for about 7 years. Note that this credit-reporting window is different from the statute of limitations – a debt can fall off your credit report while still being within the period to sue, or remain reportable after the deadline to sue has passed.
Wage garnishment. Federal law caps most wage garnishment at 25% of disposable earnings (or the amount above 30 times the federal minimum wage, whichever is less). Missouri provides additional protection, including a lower garnishment cap for the head of a family. These limits matter only after a creditor wins a judgment.
How to Verify Missouri's Rules and Get Help
Because debt classification can be technical and the deadlines are long, confirm the details before acting. You can read the actual statutes – RSMo Sections 516.110, 516.120, and 516.320 – on the Missouri General Assembly's official website. For consumer protection guidance and to file a complaint against an abusive collector, contact the Missouri Attorney General's Consumer Protection Division, which handles unfair and deceptive collection practices in the state. At the federal level, the Consumer Financial Protection Bureau (CFPB) and the Federal Trade Commission (FTC) accept complaints about debt collectors.
If you have been served with a debt lawsuit, do not delay – the deadline to respond is short and missing it can cost you the case. Consider contacting a Missouri-licensed consumer attorney or a local legal aid organization, especially when the difference between a 5-year and a 10-year deadline could decide whether the debt is collectible.

Frequently asked questions
How long can a debt collector sue me on a debt in Missouri?
It depends on the debt type. Under RSMo 516.110, written contracts and most promissory notes carry a 10-year limit. Under RSMo 516.120, open accounts and oral contracts carry a 5-year limit. Credit card debt is debated and may fall under either, so confirm which period applies to your account.
When does the statute of limitations clock start in Missouri?
It generally starts when the cause of action accrues, which for most consumer debts is the date you defaulted, typically your last payment or the first missed payment that was never cured. Selling the debt to a collector does not reset this date.
Can making a payment restart the statute of limitations in Missouri?
Yes. Missouri courts hold that a voluntary partial payment can revive the debt and start a new limitations period. A written, signed acknowledgment or new promise to pay can also restart the clock under RSMo 516.320. Confirm the deadline before paying or signing anything on an old debt.
What happens if I get sued on a debt that is too old in Missouri?
The expired statute of limitations is an affirmative defense you must raise in your written court answer. If you ignore the lawsuit, the court can enter a default judgment even on a time-barred debt, which can lead to wage garnishment. Always respond by the deadline and plead the statute of limitations.
Does a debt disappear once the Missouri statute of limitations expires?
No. The debt still exists and may stay on your credit report for about 7 years under federal law, but once the limitations period expires you can use it as a complete defense to defeat a collection lawsuit if you properly raise it in court.
