Audit
Shield.
You attest the inputs. We certify the computation.
If your inputs are correct, our Lean 4 kernel mathematically proves the calculation aligns with the Insolvency Act 1986.
£3.4M computed.Every tier verified.
Our Lean 4 kernel validates that your distribution mathematics align with statutory priority. Certificate valid only for the exact inputs provided.
SHA-256: 0x7F3A...C91B2E9ACertificate valid only for matching input hash
Every calculation backed bymathematical proof.
Formal Bridge uses Lean 4, the same theorem prover trusted by mathematicians and aerospace engineers. Your distributions aren't just calculated—they're proven correct.
Audit-Ready Certificates
Every calculation generates a cryptographic proof certificate that can be independently verified.
Statutory Compliance
IA 1986, IR 2016, and Finance Act 2020 rules encoded directly into verified functions.
Zero Runtime Errors
Proofs guarantee correctness. If the code compiles, the calculation is mathematically sound.

The logic above isn't a prediction—it's a theorem. Our kernel uses the same technology used by aerospace engineers to ensure that the code—and your distribution—is mathematically impossible to get wrong.

"In the context of a statutory distribution, a rounding variance or misapplied preference isn't merely a clerical error; it is a breach of fiduciary duty. We have replaced brittle, unvalidated spreadsheets with a formally verified kernel to ensure that every distribution is mathematically beyond reproach and strictly compliant with the Insolvency Act 1986."
/-- The prescribed part never exceeds
the statutory cap (CRITICAL BUSINESS PROOF) --/
theorem prescribedPart_le_cap (np d) :

... -- Lean verifies this automaticallyWhat this means for you: This theorem mathematically guarantees that your prescribed part calculation can never exceed the statutory cap—eliminating personal liability risk.
Why Formal Methods?
Formal Bridge leverages the same Formal Verification methodology used to secure mission-critical aerospace and cryptographic systems to eliminate computational liability in UK insolvency proceedings.
Statutory Determinism
Legal rules should not be "interpreted" by error-prone spreadsheets; they must be proven as theorems by mathematical kernels.
Zero-Failure Engineering
The same theorem-proving technology trusted by engineers to verify flight control systems now audits your distribution calculations.
Court-Ready Assurance
By encoding the Insolvency Rules 2016 and the Finance Act 2020 directly into verified functions, we provide a standard of care that exceeds traditional manual review.
