A global financial information provider preparing for a third-party audit needed to confirm compliance with a key supply agreement. The requirement was specific and high stakes: review 1,900 historic client agreements to identify a defined set of contractual data points and provide a defensible position to the auditor - within six days.

The client needed to show they had a solid handle on compliance with a key supply agreement, and do it in a way that would stand up to external scrutiny.

There was a practical constraint: internal legal teams were already balancing day-to-day priorities across business lines and jurisdictions. 

Add to that the contract estate reflected two decades of growth, system changes, and global operations. The 1,900 agreements had been created over more than 20 years, across multiple teams and regions, and they lived in different places as tools and processes evolved. 

As you’d expect with that history, there was some natural duplication, a few gaps where documents were hard to locate quickly, and a mix of document quality - especially for older, scanned files.

On top of that, the agreements were in seven languages, and the specific data points needed for the audit weren’t always described using the same wording from one contract set to the next. 

None of this is unusual in a long-running, global contracting environment - but combined with a six-day deadline, it meant the client needed a way to work systematically across the population, rather than relying on a traditional manual review.

A defensible, AI-enabled contract review and analytics program 

Radiant Law was engaged to design and deliver a contract review approach that could handle volume and complexity while maintaining legal oversight where it mattered.

‍

1) Custom infrastructure to make the contract population usable

Radiant built a bespoke contract database and wrote 18,000+ lines of custom code to:

• Deduplicate documents 
• Map agreements to legal parent entities 
• Extract the legally relevant data points needed for the compliance test 

This step addressed a common issue in large-scale contract reviews: if you can’t trust the population, you can’t trust the conclusion.

‍

2) AI + data techniques to find the right needles in a very large haystack

Radiant deployed a combination of:

• AI-assisted extraction to pull candidate data points from documents 
• Semantic search to locate meaning-aligned variants of the target terms 
• Deterministic checks to validate and standardise findings 

This mixed approach mattered because the relevant concepts lacked consistent phrasing over two decades and across seven languages.

‍

3) A purpose-built interface to speed-up human review 

Radiant developed a tailored React-based interface so reviewers could quickly navigate identified data points, compare instances across agreements, and resolve exceptions without losing time in manual document handling.

‍

4) Senior legal supervision and edge-case resolution

Experienced data licensing lawyers focused attention where the risk was higher:

• Conducted detailed analysis of higher-risk agreements 
• Supervised AI output via targeted manual review 
• Resolved edge cases and validated extraction accuracy 

‍

5) Quantifying residual risk with statistical confidence

To provide an auditor-ready position we applied:

• Statistical sampling and Bayesian modelling 
• Including Monte Carlo simulations 

These techniques were used to estimate the likelihood that any unreviewed agreements met the relevant legal test, helping the client speak in terms of confidence and residual risk.

‍

Audit-ready evidence under extreme time pressure

The combined approach, legal judgment, AI-driven analysis, and statistically supported confidence levelsenabled the client to engage credibly with the third-party auditor.

Within six days, the client was able to demonstrate that there were no substantive compliance issues within the agreement population, meeting regulatory and commercial objectives on the required timeline.

The client’s Legal team commented:

“Radiant’s team know the bank - that’s very important for us. You have that vital institutional knowledge. Radiant lawyers bring good practices to our contracting, tell us how things could be improved, how drafting could be changed. The communication and data are fantastic. Radiant has a very tech-friendly team. Sharing data and intuitive dashboards gives us all the extra insight we need.”
