White Oak Global Advisors is involved in several legal cases, most notably a dispute with former managing director Isaac Soleimani over a $143 million equity buyout, and a separate lawsuit against Marsh McLennan seeking $143 million related to the Greensill Capital collapse. The Soleimani case resulted in a court ruling that White Oak breached operating agreements by failing to properly buy out his stake.
White Oak Global Advisors, a San Francisco-based private credit firm managing billions in assets, is currently fighting multiple legal battles that could reshape how investment firms handle employee agreements and insurance claims. These lawsuits aren’t just corporate squabbles—they reveal serious questions about contract enforcement and fiduciary responsibilities in the finance industry.
If you’re an investor, employee, or business owner working with private credit firms, understanding these cases matters. The outcomes could affect how similar disputes get resolved across the industry.
This guide breaks down each major lawsuit, explains what happened, and shows you what these cases mean for White Oak’s future and the broader investment landscape.
Major Lawsuits Involving White Oak Global Advisors
White Oak faces several distinct legal challenges across different jurisdictions. Each case presents unique circumstances that expose different aspects of the firm’s operations.
The Isaac Soleimani Employment Dispute
The most financially significant case involves Isaac Soleimani, who held a 16.8% stake in White Oak Healthcare Finance LLC potentially worth up to $143 million. This wasn’t a simple employment termination—it became a complex legal battle about operating agreement violations.
A Delaware judge ruled that White Oak breached operating agreements by terminating Soleimani without first completing a fair market value buyout of his equity interest. The court found that the operating agreements clearly stated Soleimani could only be removed after his stake was purchased at fair market value.
The case didn’t end there. White Oak appealed the decision, and Delaware’s high court heard arguments on the matter. However, the company ultimately had to honor the buyout obligation.
What Made This Case Different
Most employment disputes settle quietly or get dismissed on technical grounds. This case stood out because the operating agreements contained specific provisions about equity buyouts that courts enforced strictly. The agreements gave Soleimani broad management authority that couldn’t be stripped away without following proper procedures.
A related federal case in New York’s Southern District was closed in July 2025, suggesting the parties may have reached a settlement or the matter was resolved through the Delaware proceedings.
The Greensill Capital Insurance Claim
White Oak’s involvement with the infamous Greensill Capital collapse led to another massive lawsuit. White Oak’s UK arm is pursuing insurance broker Marsh for £112 million ($143 million) in London, claiming the broker failed to properly disclose critical information about insurance coverage.
Here’s what happened: Between December 2020 and February 2021, White Oak acquired $143 million of receivables from Greensill based on insurance documentation provided by Marsh. When Greensill collapsed shortly after, White Oak discovered the insurance coverage wasn’t what they’d been led to believe.
White Oak argues their communications with Marsh demonstrated reliance on the accuracy of the insurance information provided. The lawsuit claims this lack of proper disclosure directly caused substantial financial losses.
The Greensill Connection Explained
White Oak wasn’t just caught up in Greensill’s collapse as a passive victim. The firm actually acquired assets from the bankruptcy. They purchased Greensill’s Finacity Corp. business for $7 million during the bankruptcy proceedings. The insurance lawsuit stems from transactions that occurred before the collapse, when White Oak was buying receivables they believed were properly insured.
Pension Plan Investment Management Dispute
The Trustees of New York State Nurses Association Pension Plan filed a case involving an Investment Management Agreement (IMA) that permitted White Oak to unilaterally terminate the agreement with ninety days written notice. This case centered on contractual interpretation and whether White Oak properly followed termination procedures.
Unlike the Soleimani case, this dispute involved client relationships rather than employee agreements. The pension plan trustees challenged how White Oak handled the termination of their investment relationship.
Loan Default and Personal Guaranty Cases
White Oak sued over a $10 million loan default by Prime, seeking to recover funds from Scopetta under a personal guaranty. Scopetta responded by filing a third-party complaint seeking indemnification from Prime based on the company’s operating agreement.
This case represents White Oak’s more routine business litigation—enforcing loan agreements and personal guaranties when borrowers default. It’s different from the employment and insurance disputes because White Oak is the plaintiff pursuing repayment.
Common Themes Across the Legal Cases
| Theme | Description | Cases Affected |
|---|---|---|
| Contract Interpretation | Courts strictly enforcing written agreement terms | Soleimani, Pension Plan |
| Fiduciary Responsibilities | Questions about duties owed to investors and partners | Multiple cases |
| Operating Agreement Disputes | Conflicts over LLC governance and buyout provisions | Soleimani, Loan cases |
| Insurance and Disclosure | Claims about inadequate information sharing | Greensill/Marsh |
| Employment vs. Partnership Rights | Distinguishing employee rights from equity holder rights | Soleimani |
What These Lawsuits Mean for Investors
If you’re invested in White Oak funds or considering an investment, these lawsuits raise several practical concerns you should evaluate.
Financial Impact Assessment
The financial exposure from these cases is substantial. The Soleimani buyout alone could reach $143 million. The Greensill insurance claim seeks another $143 million. Even for a firm managing billions, these aren’t insignificant amounts.
However, White Oak’s financial structure likely provides some insulation. Different legal entities within the White Oak organization are defendants in different cases. The healthcare finance affiliate involved in the Soleimani case operates separately from the main advisory business.
Reputation and Business Relationships
Legal disputes with former executives and pension plan trustees create perception problems. Institutional investors carefully evaluate not just returns, but also how firms handle conflicts and treat stakeholders.
The Greensill connection adds another layer of concern. While White Oak wasn’t directly responsible for Greensill’s collapse, their involvement in that situation became more complicated through the insurance lawsuit.
Operational Changes and Risk Management
These legal challenges highlight the importance of transparent communication and maintaining strong legal preparation to handle disputes efficiently. Firms facing similar situations typically strengthen their contract review processes and documentation practices.
White Oak likely revised their employment agreements, operating agreements, and due diligence procedures after these disputes emerged. Smart investors should ask about these changes during due diligence.
Legal Precedents and Industry Implications
Delaware Court Rulings on Operating Agreements
The Soleimani decision reinforces Delaware courts’ strict approach to enforcing operating agreements as written. Courts won’t rewrite contracts or ignore clear provisions about buyout procedures, even when the financial stakes are enormous.
This matters for anyone involved with Delaware LLCs—which includes most private equity and investment firms. If your operating agreement says equity must be purchased before termination, that sequence must be followed precisely.
Insurance Broker Liability Standards
The Marsh lawsuit tests how much responsibility insurance brokers bear when providing information about complex coverage arrangements. If White Oak prevails, it could make brokers more cautious about representations they make and increase their potential liability exposure.
Investment Advisor Termination Rights
The pension plan case explored how investment advisors can exit client relationships when agreements permit unilateral termination. The specific contract language matters tremendously—what seems like a straightforward termination clause can become contested when significant assets are involved.
How to Protect Your Interests
Whether you’re an investor, employee, or business partner working with investment firms, these cases offer practical lessons.
For Current and Prospective Investors
Request detailed information about any ongoing litigation during due diligence. Don’t just ask if lawsuits exist—find out the nature of the claims, potential financial exposure, and how they might affect fund operations.
Review fund documents carefully for provisions about liability, indemnification, and how litigation costs get handled. Some agreements charge litigation expenses to the fund, while others absorb them at the management company level.
Monitor regulatory filings and legal databases for updates on ongoing cases. Court dockets are public records that provide insight into how disputes are progressing.
For Employees Considering Equity Compensation
Get everything in writing with crystal-clear language about buyout procedures, valuation methods, and termination circumstances. The Soleimani case shows that vague or ambiguous terms will be interpreted according to their plain language.
Understand the difference between employment rights and equity holder rights. Just because you’re an employee doesn’t mean your equity can be taken without proper compensation and procedure.
Consider having an attorney review any equity or partnership agreements before signing. The upfront cost is minimal compared to potential litigation expenses later.
For Financial Service Providers
Document all representations and communications carefully, especially regarding insurance coverage, risk disclosures, and financial condition assessments. The Greensill case shows how information sharing can become contested years later.
Maintain clear records of all due diligence performed and information provided to clients or business partners. These records become critical evidence if disputes arise.
Review indemnification provisions in service agreements to understand your potential liability exposure for information or advice provided.
Current Status and Future Outlook
Recent Developments in 2025
The federal Soleimani case in New York was closed in July 2025, though the Delaware proceedings had already established the core legal principles. The Greensill insurance litigation appears ongoing in UK courts based on available information.
White Oak continues operating its investment business while managing these legal challenges. The firm hasn’t announced major restructuring or changes to its business model in response to the lawsuits.
What Happens Next
Settlement negotiations likely continue in cases that haven’t reached final judgments. Even when courts rule against a party, settlements often resolve the exact payment amounts and timing.
The Greensill insurance case could take years to fully resolve given the complexity of international insurance claims and the substantial amount at stake. UK courts handle these matters differently than US courts, potentially affecting the timeline and outcome.
Comparison: White Oak vs. Other Investment Firm Disputes
| Dispute Type | White Oak Cases | Industry Norm | Key Difference |
|---|---|---|---|
| Equity Buyout Disputes | $143M claim enforced by courts | Often settled privately | Clear operating agreement language |
| Insurance Claims | $143M against broker | Usually direct insurer claims | Third-party broker liability alleged |
| Client Terminations | Contractual 90-day notice | Varies widely by agreement | IMA permitted unilateral exit |
| Loan Enforcement | Standard default litigation | Common in lending business | Routine collection activity |
Red Flags Investors Should Watch
Beyond these specific lawsuits, certain warning signs suggest when an investment firm might face legal troubles:
Frequent executive turnover, especially at the managing director or partner level, can signal internal conflicts. The Soleimani dispute emerged after his departure from the firm.
Involvement with failed financial institutions raises questions about due diligence and risk management. White Oak’s Greensill exposure became problematic even though they weren’t directly responsible for the collapse.
Complex organizational structures with multiple affiliated entities can obscure liability and make it harder to understand risk exposure. White Oak’s various affiliated LLCs show this complexity.
Litigation with institutional investors or pension funds draws regulatory attention. These investors conduct thorough due diligence, so disputes suggest serious underlying problems.
