Capital Markets
Advisory and contentious work across securities issuance, listings and market regulation, including representation before specialist tribunals.
The firm
A small bench of senior lawyers, deliberately.
Osborne Law Practice was founded on a simple discipline: the lawyer who wins your instruction is the lawyer who argues your case. Nothing is delegated downwards to fill a billing sheet.
“Preparation is the only advantage that cannot be bought on the courthouse steps.”

Method
Judgment, applied in a fixed order.
Every mandate passes through the same four stages, so nothing depends on who happens to be in the room.
01
Confidential intake
A partner reviews every enquiry personally, establishes conflicts clearance and agrees the scope of the retainer in writing.
02
Case theory
We build the theory of the matter before we build the file — the facts, the forum, the exposure and the realistic range of outcomes.
03
Strategy & staffing
Cross-disciplinary teams are assembled from day one so tax, insolvency and litigation questions are answered together, not sequentially.
04
Execution & reporting
Structured reporting after every hearing or milestone, with commercial recommendations rather than a recital of procedure.
Record
Reported matters, decided.
A selection of mandates across tax enforcement, criminal appeals, banking recovery and asset forfeiture.

What instructing clients say.
They took over a matter three years into trial and turned it. The clarity of advice was the difference — we always knew our exposure.
Responsive, commercially minded and genuinely fearless in court. Our recovery portfolio has never been managed better.
The tax team dismantled an assessment that two other firms had told us to settle. Rare judgment.
