Connecticut: Statute of Limitations on Debt Collection

Requirements one by one

Governing law

Connecticut's contract-debt deadlines live mainly in Chapter 926 of the
General Statutes: § 52-576 sets the general 6-year period for "an account,
or any simple or implied contract, or any contract in writing," and § 52-581
sets a 3-year period for an oral contract, but only one that is still
executory. A debt for the sale of goods is carved out of both and gets its
own 4-year period under § 42a-2-725, part of Connecticut's enactment of UCC
Article 2. A separate, narrow statute, § 52-176 (located in the Evidence
chapter, not the limitations chapter), requires a signed writing for an
acknowledgment or promise to revive a claim, but only against a deceased
debtor's estate. Connecticut has no borrowing statute for out-of-state debt.
And the Consumer Collection Agency statutes (§ 36a-805) impose a specific
time-barred-debt disclosure duty on licensed collection agencies.

How long you have on a written debt

Six years. Section 52-576(a) covers "an account, or any simple or implied
contract, or any contract in writing." Connecticut courts have gone further
and held that this same 6-year period, not the shorter oral-contract
statute, also governs an EXECUTED oral contract, meaning one where the
creditor's side has been completely performed and only the debtor's payment
remains: "Section applies to money demand on executed simple contract," and
a Connecticut Appellate Court decision confirms "Section's 6-year statute of
limitations applied to executed oral contract, as opposed to 3-year statute
of limitations in Sec. 52-581 which applies only to executory contracts" (76
CA 599). A debt for the sale of goods is expressly excluded from § 52-576 (§
52-576(c)) and instead gets a shorter 4-year period under § 42a-2-725.

How long you have on an oral or unwritten debt

Three years, but only if the oral contract is still executory. Section
52-581(a) covers "any express contract or agreement which is not reduced to
writing," but Connecticut's own official case annotations to this section
state plainly: "this section is restricted to executory contracts." Once a
party's performance on an oral contract is complete, the far more common
situation once a creditor is trying to collect an unpaid debt, § 52-576's
6-year period applies instead, not this 3-year one.

When the clock starts

The default rule is the date of breach. Connecticut's own case law
interpreting § 52-576 confirms the "statute of limitations to run from the
time when the cause of action accrues," and courts have applied this to
specific debt scenarios (for example, a demand note's cause of action
accrues on its execution and delivery). A UCC sale-of-goods claim under §
42a-2-725 accrues when the breach occurs "regardless of the aggrieved
party's lack of knowledge of the breach," with only a narrow exception for a
warranty explicitly extending to future performance.

Can a payment or promise restart the clock?

Yes, and Connecticut's rule for an ordinary living debtor is unusually
loose, because it comes from common law, not a signed-writing statute.
Connecticut's own official annotations to § 52-576 state that the statute's
"defense can be lost by an unequivocal acknowledgment or recognition of
debt or payment on account", with case law going so far as to hold that
even a spoken statement ("I will take care of it as soon as I can") is
enough to take a debt out of the statute, and that "a payment to toll [the]
statute of limitations must be made or authorized by the debtor." No signed
writing is required for any of this. The ONE Connecticut statute that does
impose a signed-writing requirement, § 52-176, is narrower than it might
first appear: it applies only "in any action against the representatives of
a deceased person", an acknowledgment or promise in that specific,
narrower context must be in a writing signed by the party to be charged,
though even there the statute preserves the separate effect of a bare
payment of principal or interest.

Is there a special rule for consumer debt?

None was found. The same § 52-576/§ 52-581 periods apply whether the debt is
a business contract or a personal credit-card balance; Connecticut has no
separate, shorter limitations period specifically for consumer-credit-
transaction debt. Connecticut's Creditors' Collection Practices Act and
Consumer Collection Agency statutes regulate collection conduct, licensing,
harassment, required disclosures, not a different deadline to sue.

What if the debt originated in another state?

Connecticut has no borrowing statute reaching contract debt at all. A
law-review 50-state survey of borrowing legislation lists Connecticut among
the states with none on the books. Without one, Connecticut courts fall back
on the state's own common-law choice-of-law principles to decide which
state's substantive law, and with it, which limitations period, actually
governs the claim, rather than applying any fixed shorter-of or longer-of
rule by statute.

What actually happens once the deadline passes?

For an original creditor suing directly, expiration is just an ordinary
affirmative defense the debtor has to raise. But Connecticut goes further
for a licensed consumer collection agency (a category that includes a debt
buyer under Connecticut law): § 36a-805(a)(14) makes it a prohibited
practice for the agency to fail to disclose, in its very first communication
and in type no smaller than 10-point, that "the law limits how long you can
be sued on a debt" and that, because of the debt's age, the agency "will
not sue you for it." That's a disclosure that doubles as a promise not to
sue, not just a generic warning, and it applies whether or not the debt has
also become obsolete for credit-reporting purposes (the required wording
differs slightly between the two situations). This duty doesn't reach an
original creditor collecting its own debt directly.

What trips people up

People often assume Connecticut's shorter 3-year oral-contract period covers
any unwritten debt, but it only reaches a still-executory oral agreement, once the creditor has already delivered the money, goods, or services and
only payment is outstanding, the LONGER 6-year period applies instead, even
with nothing in writing. The bigger trap is on the revival side: because
Connecticut's ordinary rule for a living debtor comes from unwritten case
law rather than a signed-writing statute, even a casual spoken acknowledgment
of an old debt, not just a payment, can take it out of the statute. And
Connecticut's lack of any borrowing statute means moving to Connecticut from
a state with a shorter deadline doesn't automatically help a debtor the way
it might in a state with a classic shorter-of borrowing rule; the outcome
instead turns on Connecticut's own common-law choice-of-law analysis.

Common questions

I never signed anything for this debt, does that mean Connecticut only
gives the creditor 3 years?
Not necessarily. Connecticut's 3-year oral-contract period only applies to
an agreement that's still executory. If the creditor already fully performed
(lent the money, delivered the goods, provided the service) and only your
payment is outstanding, Connecticut courts treat that as governed by the
6-year period instead, even without a signature.

I told a debt collector on the phone that I still owed the money, did
that restart the clock?
Quite possibly, and Connecticut doesn't require a writing to make that
happen for an ordinary debt against a living debtor, case law treats even
an oral, unequivocal acknowledgment as capable of removing the statute's
bar.

Can a debt collector still sue me in Connecticut after the deadline
passes?
A licensed consumer collection agency has a specific legal duty to tell you,
in writing, that it will not sue you once your debt is time-barred. An
original creditor collecting its own debt directly isn't covered by that
specific rule, though you can still raise the expired deadline as a defense
if sued.

Does moving to Connecticut from a state with a shorter deadline help a
creditor sue me here?
Connecticut has no borrowing statute at all, so there's no automatic
shorter-of-two-periods rule. Which state's law, and limitations period, actually applies depends on Connecticut's own common-law choice-of-law
analysis.
