Mississippi Construction Liens: Whether Ambiguous Invoice Attachments Can “Specify” the Statutory “Last Date” Under Miss. Code Ann. § 85-7-405(1)(b)

Introduction

Cuevas Machine Company v. Calgon Carbon Corporation (5th Cir. Apr. 15, 2026) is a diversity appeal arising from a disputed attempt to foreclose two Mississippi construction liens totaling roughly $1.23 million. Cuevas Machine Company (“Cuevas”), a subcontractor providing fabrication and machining services at Calgon Carbon Corporation’s (“Calgon”) filtration plant in Hancock County, recorded two liens after it alleged nonpayment flowing from a pay-when-paid arrangement with the general contractor, O’Neal Constructors (“O’Neal”).

The central issue is intensely practical: Mississippi’s construction lien statute requires a lien to “specify” the date the claim was due—expressly defined as “the last date the labor, services or materials were supplied to the premises.” Cuevas’s lien forms did not state that date in the body of the lien. Instead, Cuevas attached invoices bearing dates, but those invoices did not clearly reveal whether the dates were (i) the dates work was performed, (ii) invoice-generation dates, or (iii) some other internal accounting dates. The district court dismissed the foreclosure complaint with prejudice under Rule 12(b)(6), concluding via an Erie prediction that the liens were not enforceable. On appeal, the Fifth Circuit declined to make its own Erie guess and certified the question to the Mississippi Supreme Court.

Summary of the Opinion

The Fifth Circuit did not decide whether Cuevas’s liens are valid under Mississippi law. Instead, it held that Mississippi authority is unclear on whether dated but ambiguous invoice attachments can satisfy the statutory requirement that the lien “specify” the “last date” labor/services/materials were supplied. Because the answer is determinative and no controlling Mississippi Supreme Court precedent addresses it, the Fifth Circuit certified the issue pursuant to Mississippi Rule of Appellate Procedure 20(a).

The certified question asks whether attaching invoices that do not “plainly indicate” the last-supplied date nonetheless satisfies Miss. Code Ann. § 85-7-405(1)(b)’s requirement that an enforceable lien “specify the date the claim was due.”

Analysis

Precedents Cited

1) Federal procedural framework and Erie methodology

McKay v. LaCroix, 117 F.4th 741 (5th Cir. 2024): Supplies the Rule 12(b)(6) standard of review (de novo; accept well-pleaded facts, reject legal conclusions and unwarranted inferences). This matters because lien validity was tested at the pleading stage, without factual development.
Civelli v. J.P. Morgan Sec., L.L.C., 57 F.4th 484 (5th Cir. 2023): Confirms de novo review of a district court’s Erie guess, framing the appellate court’s freedom to disagree with the district court’s prediction of Mississippi law.
Compliance Source, Inc. v. GreenPoint Mortg. Funding, Inc., 624 F.3d 252 (5th Cir. 2010): Reinforces that Mississippi substantive law governs in diversity—critical because lien creation is a matter of state substantive law.
Paz v. Brush Engineered Materials, Inc., 555 F.3d 383 (5th Cir. 2009): States the two-step Erie approach—look for dispositive Mississippi Supreme Court decisions; if none, forecast how that court would rule.
Jorge-Chavelas v. La. Farm Bureau Cas. Ins. Co., 917 F.3d 847 (5th Cir. 2019), and Howe v. Scottsdale Ins. Co., 204 F.3d 624 (5th Cir. 2000): Identify permissible sources for an Erie prediction (state decisions, interpretive principles, secondary sources, and intermediate appellate decisions). The panel relied on this framework to explain why the available Mississippi sources were insufficiently clear.
Erie R.R. Co. v. Tompkins, 304 U.S. 64 (1938): The foundational basis for why federal courts must apply state substantive law and why the district court was required to make (and the Fifth Circuit to review) an Erie prediction in the first place.

2) Mississippi statutory interpretation principles

Am. Tower Asset Sub, L.L.C. v. Marshall Cnty., 324 So. 3d 300 (Miss. 2021): Provides the core interpretive rule—apply plain meaning when unambiguous; interpret to ascertain legislative intent when ambiguous or silent.
In re Guardianship of Duckett, 991 So. 2d 1165 (Miss. 2008): Quoted (via Am. Tower) for the “intent of the legislature” approach where interpretation is appropriate.
Saul v. Jenkins, 963 So. 2d 552 (Miss. 2007): Reinforces Mississippi’s emphasis on legislative intent in construing statutes—particularly salient given the 2014 lien-law overhaul.

3) Mississippi lien-law decisions and the liberal vs. strict compliance tension

Land Holdings I, L.L.C. v. GSI Servs., L.L.C., 265 So. 3d 147 (Miss. 2019): The only Mississippi Supreme Court decision interpreting the current version of § 85-7-405(1)(b) cited by the panel. It construed strictly the requirement that work be performed within 90 days of filing, but it did not address whether a lien can omit an element in the lien’s text and supply it ambiguously via attachments. The Fifth Circuit treated Land Holdings as informative on strictness in some contexts, but not dispositive here.
Jones Supply Co. v. Ishee, 163 So. 2d 470 (Miss. 1964): States that statutory prerequisites must be strictly complied with. The Fifth Circuit, however, noted that Jones Supply’s strictness was motivated by notice-protection concerns (notice to the lienee), which is not perfectly aligned with the question of lien creation and what counts as “specif[ying]” the last-supplied date.
Wortmann & Mann, Inc. v. Frierson Bldg. Supply Co., 184 So. 2d 857 (Miss. 1966), Jones v. Alexander, 18 Miss. 627 (1848), and Federated Mut. Ins. Co. v. McNeal, 943 So. 2d 658 (Miss. 2006): These support the “creatures of statute” view—liens (including analogous statutory liens) must adhere to mandatory statutory language. The panel cited these to show a robust line of authority favoring strict compliance.
Chancellor v. Melvin, 52 So. 2d 360 (Miss. 1951), Morris v. Shryock & Rowland, 50 Miss. 590 (1874), and Sharpe v. Spengler, 48 Miss. 360 (1873), plus In re Purvis, 293 F. 102 (S.D. Miss. 1923): These represent the older, lienor-friendly “liberal construction” tradition—reasonable construction in favor of maintaining liens and effectuating lien statutes’ remedial purposes. The Fifth Circuit acknowledged this line but emphasized that it conflicts with the strict-compliance line and mostly predates the 2014 statutory rewrite.

4) Analogies and “attachments as part of an instrument”

United Miss. Bank v. GMAC Mortg. Co., 615 So. 2d 1174 (Miss. 1993): Cited by analogy for the proposition that key elements in attachments may be treated as part of the primary instrument (there, a deed of trust). The Fifth Circuit used this to show that Mississippi law could be receptive to incorporation-by-attachment arguments, but it did not resolve whether the lien statute permits such flexibility—or whether ambiguity in attachments defeats “specify.”

5) Inapposite lien cases and tax-sale strictness as contextual signals

KD Oak Grove, L.L.C. v. Warren & Warren Asphalt Paving, L.L.C., 324 So. 3d 1134 (Miss. 2021), and Strauss v. Baley, 58 Miss. 131 (1880): Cited to show that some lien-related precedent addresses different statutory provisions (litigation notices; priority disputes) and does not answer the “specify the last date” question.
Hart v. Catoe, 390 So. 2d 1001 (Miss. 1980), Cristiana Tr. v. Ciota, 291 So. 3d 780 (Miss. Ct. App. 2019), C.F.P. Properties, Inc. v. Roleh, Inc., 67 So. 3d 575 (Miss. Ct. App. 2010), and Lawrence v. Ranking, 870 So. 2d 673 (Miss. Ct. App. 2004): Not lien cases, but cited as a “related area” in which Mississippi courts apply strict statutory compliance (tax sales), suggesting that modern Mississippi jurisprudence may be less inclined toward flexible validation when statutes impose detailed prerequisites.

6) Certification standards

Swindol v. Aurora Flight Scis. Corp., 805 F.3d 516 (5th Cir. 2015): Supports certification where a determinative question lacks clear controlling Mississippi Supreme Court precedent.
Stanford ex rel. Phillips v. Brandon Nursing & Rehab. Ctr., L.L.C., 160 F.4th 118 (5th Cir. 2025): Supplies the three-factor certification analysis: closeness/sources, comity, and practical limits (delay and framing).
Johnson v. Miller, 98 F.4th 580 (5th Cir. 2024): Quoted for the admonition that an Erie guess without adequate state-law guidance is “a leap into the dark,” reinforcing the panel’s preference for certification over prediction.

Legal Reasoning

The court’s reasoning proceeds in three steps.

Identify the statutory requirement that drives enforceability. Miss. Code Ann. § 85-7-405(1) states that a construction lien “must be created and declared” per the statute and that failure of “any” enumerated provision makes the lien not “effective or enforceable.” Section 85-7-405(1)(b)’s template then instructs that the lien “shall be in substance” as follows, while requiring the lienor to “specify” certain data, including the amount and “the date the claim was due,” which the statute equates to “the last date the labor, services or materials were supplied to the premises.”
Explain why existing Mississippi law does not resolve whether attachments can satisfy “specify”—especially when the attachments are ambiguous. The Fifth Circuit acknowledged an argument for flexibility: the “in substance” language suggests the statute focuses on content rather than rigid form, and United Miss. Bank v. GMAC Mortg. Co. hints that attachments can be treated as part of a legal instrument. But the panel then highlighted the core uncertainty: even if attachments count, must the “last date” be stated plainly (i.e., unambiguously identifiable as the last-supplied date), or is it enough that documents contain dates from which the “last date” might be inferred? On that precise point, the Mississippi Supreme Court has not spoken.
Choose certification to avoid misapplying a rewritten statute with significant economic consequences. The panel stressed that § 85-7-405(1)(b)’s current language was adopted as part of a “major overhaul” in 2014 (S.B. 2622), leaving limited interpretive precedent. Given competing lines of older “liberal construction” cases and “strict compliance” cases—and given that modern decisions (including in other statutory contexts) often require strict adherence—the court found the question close and determinative. Applying the Stanford factors, it concluded that comity and the need for a definitive state-law answer outweighed delay concerns, and it certified the question under Miss. R. App. P. 20(a).

Impact

Although the Fifth Circuit did not announce a merits rule, the opinion is significant in at least four ways:

It squarely tees up a high-stakes interpretive choice for Mississippi lien practice. The Mississippi Supreme Court’s answer will determine whether lienors can rely on invoices to “specify” the “last date,” and, crucially, how clear those invoices must be. A strict answer would push practitioners to state the “last date” expressly in the lien body (or to use attachments that plainly label the last-supplied date). A flexible answer could preserve liens where the “last date” is reasonably inferable from attachments.
It highlights the practical drafting risk created by “templated” statutory forms with mandatory “specify” fields. Because § 85-7-405(1) makes noncompliance fatal (“shall not be effective or enforceable”), lien-recording errors can extinguish leverage for payment and undermine foreclosure remedies.
It signals that post-2014 lien questions may be resolved through state-court clarification rather than federal prediction. The opinion reflects an institutional preference to avoid federal-law “guesses” where a modern Mississippi statute has limited construction and where outcomes carry meaningful economic impact.
It may influence pleading-stage strategy. Because the case was dismissed under Rule 12(b)(6), the eventual Mississippi ruling may affect when lien disputes can be resolved on the pleadings versus requiring evidentiary development about what invoice dates mean and whether they correspond to “the last date” work was supplied.

Complex Concepts Simplified

Construction lien: A statutory security interest that allows those who improve real property (contractors, subcontractors, material suppliers) to claim a lien against the property to secure payment.
“Specify” (in a lien statute): To state a required item with sufficient clarity and definiteness. The dispute here is whether “specify” requires an explicit statement of the “last date” (e.g., “Last date of work: Oct. 3, 2023”) or whether dated documents that do not clearly identify what the dates represent can suffice.
“Last date the labor, services or materials were supplied”: The final day on which the lien claimant actually furnished work/services/materials to the project. Lien statutes often use this date to measure filing deadlines and to provide notice-relevant information to owners and lenders.
“Substantial compliance” vs. “strict compliance”: “Substantial compliance” tolerates minor defects if the filing fulfills the statute’s essential purposes; “strict compliance” demands adherence to statutory prerequisites, especially when the statute says noncompliance makes the lien unenforceable.
Erie guess: When a federal court in a diversity case must predict how the state’s highest court would resolve an unsettled issue of state law.
Certification: A process allowing a federal court to ask the state’s highest court to answer a determinative question of state law, reducing the risk of an incorrect Erie prediction.
Rule 12(b)(6): A motion to dismiss for failure to state a claim. Here, it was used to argue that, even assuming Cuevas’s allegations are true, the liens are invalid as a matter of Mississippi law.

Conclusion

Cuevas Machine Company v. Calgon Carbon Corporation is a careful federalism-and-statute case: the Fifth Circuit recognized that Mississippi’s post-2014 construction lien regime contains mandatory “specify” requirements, yet Mississippi precedent is divided between liberal and strict approaches and does not address whether ambiguous invoice attachments can satisfy the “last date” requirement of Miss. Code Ann. § 85-7-405(1)(b). Rather than entrench an uncertain Erie prediction that could distort Mississippi lien law, the court certified a narrow but consequential question to the Mississippi Supreme Court. The forthcoming state-court answer is poised to set the operative drafting standard for lien claimants and a predictable enforceability benchmark for owners, lenders, and contractors across Mississippi.
