Differing Site Conditions Claim Requires a Misrepresentation

May 14, 2026 — David Adelstein - Florida Construction Legal Updates
If you are entertaining a differing site conditions claim, consider this Third District Court of Appeals case from the mid-90s. In Hendry Corp. v. Metropolitan Dade County, 648 So.2d 140 (Fla. 3d DCA 1995), a contractor was hired by Dade County to demolish the old Rickenbacker Causeway in Miami. The original 1941 plans of the causeway were made available to contractors. The lowest bidding contractor that was awarded the project based its bid “on its conclusion that the pilings supporting the old bridge were made of concrete.” Hendry, supra at 141. The contractor based this conclusion on the original plans, its visual observation, and experience. Read the full story...

Federal Court Highlights the Strategic Value of Additional Insured Coverage

June 22, 2026 — Michael S. Levine - Hunton Insurance Recovery Blog
A recent decision from the District of Maryland underscores a recurring—but often underutilized—opportunity for policyholders: securing and enforcing additional insured coverage under another party’s liability policy. In Charter Oak Fire Insurance Co. v. Builders Premier Insurance Co., the court held that an equipment lessor qualified as an additional insured under the lessee’s policy and was entitled to a primary defense. The decision is a useful reminder that additional insured coverage can fundamentally shift defense obligations and materially reduce a policyholder’s exposure. We build on the decision to highlight the practical steps policyholders should take to ensure that all potentially available insurance is identified and pursued. Read the full story...

Alert: Fraudulent Notice of Nonpayment Defense Applies to Payment Bond Claims

April 27, 2026 — David Adelstein - Florida Construction Legal Updates
Under Florida’s Lien Law, there’s an affirmative defense or affirmative claim known as a “fraudulent lien.” The fraudulent lien defense or claim is set out in Florida Statute s. 713.31. This defense also extends to payment bond claims, whether under a private statutory payment bond (Florida Statute s. 713.23) or a public payment bond (Florida Statute s. 255.05), as it pertains to the notice of nonpayment. A notice of nonpayment needs to be served within 90 days from final furnishing to preserve a claimant’s rights against the bond. However, there really has not been a case, until now, that discusses a “fraudulent notice of nonpayment.” In K&M Electric Supply, Inc. v. Brown Electrical Solutions, LLC, 51 Fla.L.Weekly D672a (Fla. 4th DCA 2026), a prime contractor and surety prevailed at the trial level on their fraudulent notice of nonpayment defense based on a supplier’s notice of nonpayment and action against a public payment bond (under Florida Statute s. 255.05).

The “Pay When Paid” Clause in California Construction—Strategies as the Battle Continues

August 03, 2026 — William L. Porter - Porter Law Group
It is well known in California Construction circles that the “Pay If Paid” clause is illegal in this state. There is a great distinction, though, between this clause and a similar clause, known as a “Pay When Paid” clause. A pay if paid clause allows a contractor to tell a subcontractor that if the contractor is unpaid for the subcontractor’s work, then the contractor has no legal obligation to pay the subcontractor, ever. For a great variety of reasons, the California Supreme Court, in the case of Wm. R. Clarke Corp v. Safeco Ins. Co. of America (1997) 15 Cal.4th 882, declared this type of clause illegal in California Construction. Although the pay if paid clause is illegal in California, the pay when paid clause is still perfectly legal and is found in many subcontracts that contractors issue to their subcontractors. The pay when paid clause allows a contractor to delay paying its subcontractors until the dispute between the contractor and the property owner over payment has been resolved and the contractor is paid by the property owner. Although seemingly reasonable (since it merely delays payment until the contractor is paid by the owner, thereby providing a funding source to pay subcontractors), significant problems still arise.

The AI Knows Too Much: When Employees Feed Trade Secrets into Generative AI Tools

April 14, 2026 — Kazim A. Naqvi & John V. Mysliwiec - Sheppard
Every time an employee pastes proprietary source code, a customer list, or a confidential business strategy into ChatGPT, Claude, or Google Gemini, they may be quietly dismantling the legal protections that make those secrets worth protecting. Courts and regulators are only beginning to grapple with this problem, and right now, the burden of preventing it falls squarely on employers. The Legal Stakes Under the federal Defend Trade Secrets Act (“DTSA”) and the Uniform Trade Secrets Act (“UTSA”) as adopted across most states, a trade secret plaintiff must show that the information at issue was subject to reasonable measures to maintain its secrecy. Courts have historically credited measures like confidentiality agreements, physical access controls, and employee training—but those safeguards were designed for a world of thumb drives and disgruntled employees. They were not built for a world where a well-meaning engineer can, in seconds, transmit an entire corpus of proprietary data to a third-party AI platform operating under terms of service that may permit the provider to use inputs for model training.
