Costs Management

Costs work, from first instruction to final recovery.

We advise law firms and their clients on funding, run costs case management through the life of a matter, and handle detailed assessment when it's time to recover.

What we do

Three points along the same beam — costs work, from first instruction to final recovery.

01

Funding & Panel Advice

We advise on retainer structure, funding routes and panel or tender submissions, so the right funding model is in place before the work starts.

02

Costs Case Management & Performance

We set and monitor budgets through the life of a case, tracking spend against the approved budget so there are no surprises at the end.

03

Detailed Assessment & Solicitors Act Disputes

Whether costs are being recovered from the other side or a bill is being challenged between solicitor and client, we handle the assessment process end to end — preparing, negotiating and, where needed, arguing it before a costs judge.

About

Costs Management has advised law firms and their clients on costs since 2005 — and has widened from detailed assessment into funding and case management, so the same team can help from the first retainer through to final recovery.

Jason Harvey Osborn founded Costs Management in 2005 as a qualified Costs Lawyer with Higher Rights of Audience and training as a mediator. Before setting up the practice, he was Litigation Group Costs Manager at DLA Piper and worked in the costs team at Hogan Lovells.

That background shapes how the practice works today: institutional clients — international law firms, global commercial organisations and high-value individuals — get costs advice that understands both sides of the table, from the funding decision through to the final bill.
