One hundred fifty-five investors. Zero delays.

Carta Law has long supported a leading global alternative investment management firm across transaction KYC for multiple fund cycles across its private equity and private credit platforms, working in close coordination with the firm’s internal and external counsel. As the firm's most recent fundraises gained momentum, it extended Carta Law’s existing mandate to cover investor due diligence on an interim basis, bridging the transition between its prior outsourced provider and its incoming fund administrator.

Given the multi-jurisdictional nature of the firm's fund management structures, the engagement required navigation of overlapping AML regimes—UK, U.S., and EU (via Luxembourg)—across the investor base. Carta Law worked directly alongside the firm's in-house legal and compliance team for the duration of the engagement and embedded Carta Law directly alongside its in-house legal and compliance team.

The challenge

Investor onboarding for multi-jurisdictional private capital fundraises is one of the most demanding workstreams a sponsor can face. This firm's fund management structure brought several AML regimes into scope—UK, U.S., EU and Luxembourg—each with its own documentation expectations, audit posture, and counterparty conventions. The Luxembourg regime in particular sets a high bar, with frequent audits and granular documentation requirements that leave no margin for inconsistency.

Its in-house legal and compliance team sought support to deliver high-volume investor AML/KYC on a tight closing timeline, without compromising quality or consistency. The challenge was not purely one of capacity: Uniform standards across documentation, audit-readiness, and counterparty communication were equally critical.

With closing milestones approaching, the firm required a trusted specialist with the experience and bench strength to step in and deliver at pace, without a period of learning or disruption.

The solution

Building on the established transaction KYC relationship, Carta Law extended its remit to manage the firm's investor due diligence as an embedded extension of the in-house legal and compliance function. The engagement model was designed around consistency, visibility, and speed:

• Direct coordination with external fund counsel on a regular cadence, removing client-side bottlenecks and keeping every investor process moving

• A customized tracker mapped to the jurisdiction’s documentation and audit requirements and built to withstand regulator scrutiny

• Weekly calls to surface any issues early and ensure proactive resolution across the investor base

• A lean escalation protocol—Carta Law revert to the in-house team only where strictly necessary, preserving senior bandwidth for strategic priorities

• Cross-border expertise deployed to handle complex investor profiles without impacting the fund’s overall closing timetable
