UBS

The 2023 merger of UBS and Credit Suisse created one of the most complex legal integration challenges in recent financial history. UBS's in-house legal team faced the immediate task of absorbing an unknown portfolio of open matters, outside counsel relationships, and billing arrangements from Credit Suisse — all without disrupting active legal work or surrendering the cost discipline the function had built over years. In corporate legal operations, post-merger rationalization is notoriously opaque: fee structures vary by firm, matter, and timeframe, making it nearly impossible to identify overspending through manual review alone. Without a structured, data-driven approach, the risk was absorbing Credit Suisse's cost inefficiencies wholesale.

UBS partnered with UnitedLex and Legal Decoder to apply AI-driven analytics and business intelligence to the top 25 matters transitioning from Credit Suisse. The engagement focused on granular, line-item billing data — the level at which staffing decisions, task delegation, rate compliance, and billing guideline violations actually surface. Legal Decoder's analytics platform ingested and structured the billing records, enabling pattern recognition across timekeeper categories, fee arrangements, and work allocation models that would be invisible to spreadsheet-based review. UnitedLex translated the analytical findings into actionable recommendations, working directly with UBS's in-house legal operations team to restructure outside counsel relationships, renegotiate fee arrangements, and establish ongoing spend monitoring processes. The engagement was scoped as a defined project rather than a platform deployment, prioritizing speed of insight over long-term technology integration.

The engagement delivered a 25% reduction in legal spend across the transitioning matter portfolio — a material outcome given the scale of the Credit Suisse book of business. Beyond the headline number, the project produced durable operational improvements:

• Strengthened budget controls and billing guideline enforcement across transitioned matters
• Identified long-term efficiency opportunities in staffing models and work allocation
• Established a framework for ongoing spend analysis and outside counsel performance monitoring
• Recognized with the 2025 ACC Value Champions Award for excellence in legal innovation

The results demonstrate that post-merger legal integration can generate measurable cost savings when approached analytically rather than administratively.

• Line-item billing analysis reveals cost reduction opportunities — overstaffing, rate creep, task misallocation — that aggregate spend reports systematically hide.
• Post-merger legal integration is a high-value moment to rationalize outside counsel relationships before inherited inefficiencies become entrenched.
• Scoping the AI engagement around a defined matter set (top 25 transitioning matters) produced faster, more actionable results than a broad platform rollout.
• Analytics alone don't reduce spend — the in-house team must be empowered and resourced to act on findings through renegotiation and process change.
• Third-party validation of findings, as through an ACC award, strengthens the legal department's credibility when presenting cost outcomes to finance and leadership.
