Positioned for the few. Prepared for the severe.

Restoring Operational Control. Eliminating Commercial Impasses.

Commercial disputes are rarely just legal disagreements—they are structural friction points placed on your capital, assets, and freedom to operate. We dismantle the friction so you return to total agency.

Initiate confidential approach

Resolved, not managed. Standard litigation manages conflict; we focus on resolving it. We establish strategic leverage long before formal proceedings begin—ensuring that by the time an adversary evaluates their position, a favourable resolution is the only logical path forward.

Who we act for

Positioned for the few.

We represent a strictly limited group of principals, family offices, and trustees whose affairs are complex, whose disputes are severe, and whose privacy is non-negotiable.

Most clients engage us when conventional legal strategy has stalled and the impasse appears total. From that moment, the distinction between counsel and principal disappears: your commercial objective becomes our sole direction, pursued with complete alignment and discretion.

The method

Outcomes are decided by preparation, not courtroom drama.

Long before formal letters are served or court documents are filed, the matter is mapped to

its clear commercial conclusion.

Disputes are rarely won in argument. They are won in the weeks prior—through deep factual analysis, clear-eyed strategic distance, and the meticulous preparation that makes an adversary’s position untenable.

How We Work

Rigorous fact-finding. Senior legal strategy. Decisive execution.

01

Counsel-Led Command

Senior counsel directs every matter from day one. We determine what evidence is pursued, how leverage is applied, and how the impasse is broken—ensuring single-command clarity across all legal actions.

02

Targeted Fact-Finding & Investigation

Where standard legal discovery reaches its limit, we work alongside specialised corporate investigators within strict legal boundaries set and protected by counsel. We surface the financial facts, corporate structures, and hidden details necessary to dissolve an opponent’s leverage.

03

Decisive Resolution & Asset Recovery

We build evidentiary positions designed to secure early, out-of-court settlements. When formal judgment is required, we pursue it through to complete cross-border enforcement—including freezing orders and asset recovery. A matter is only complete when capital and control are restored.

Principal Partner

Anthony Sissian

Anthony Sissian leads every matter the firm accepts. His practice sits at the intersection of commercial litigation, asset recovery, and high-stakes private disputes—where the facts that decide an outcome are rarely the ones in the file.

Engaged primarily after conventional legal strategy has reached an impasse, his methodology remains constant: establish the facts in full, anticipate the adversary’s moves, and resolve the dispute on terms that hold. The vast majority of his work concludes long before entering a courtroom.

This firm exists for a single purpose. We are not a general practice. When clients engage us, they require absolute alignment and an unyielding voice. We deploy with complete dedication to the commercial objective—because nothing matters more than restoring total control.

Practice

We are engaged when the impasse is absolute, the stakes are severe, and traditional strategy has reached its limit.

01

Asset Recovery and Enforcement

A judgment is only worth what can be recovered.

We locate, freeze and recover assets that have been concealed, dissipated or moved beyond easy reach, including assets held through third parties, trustees, nominee directors and layered structures across several jurisdictions. Through our specialist partners we establish who ultimately owns and controls an asset even where the paper trail has been deliberately broken. We deploy multi-jurisdictional freezing orders, asset tracing, and direct enforcement to achieve absolute operational recovery.

02

Private Client Disputes

When the matter is personal, the approach is not.

Disputes within families, between business partners, with former advisers or across estates and trusts carry a weight that commercial litigation does not. Where the dispute turns on what someone has hidden, we find it. Confidentiality is not a feature of this work. It is the condition of it. We provide an unyielding, clinically detached voice to resolve complex familial and corporate friction.

03

Fraud, Corruption and White-Collar Matters

Proof of wrongdoing. Or proof that there was none.

We act for those who need to prove fraud and for individuals and companies who need to defend against allegations that do not survive scrutiny. Every step is designed with admissibility in mind. Evidence that cannot be used in court is of no use to our clients, and we do not pursue it.

04

Complex Commercial Litigation

Complex disputes are won on their evidentiary foundation.

High-value disputes and arbitrations where the facts are contested, the documents are incomplete and the other side is well resourced. We identify what must be established, locate the evidence that establishes it, and anticipate how the opponent will respond before they do. We construct an unshakeable evidentiary foundation that forces well-resourced opponents to settle when they see what we hold.

05

Reputation and Hostile Campaigns

Find who is behind it. Stop it. Hold them to account.

Coordinated attacks on an individual, a family or a business rarely happen by accident. We identify the people and interests behind hostile campaigns, establish what they have said and done, and bring the legal response that ends it.

Hard cases are won before they are argued.

The calls that reach us come late, with a great deal riding on them and little time to spare. If that is your position, this is the work we were built for.

Your matter is not a file to us. It is a point to be made, on your behalf, to whoever assumed you would not push back. And we will look after you as we would our own.

For the moments that matter.
