Prior to setting up Harold & McCormack Law, Ashleigh worked exclusively in top 50 law firms before running her own consultancy practice.

Values

Client Care to the Standard We’d Expect Ourselves

We give every client the attention, commitment and respect, we would want if we were in your shoes.

Clarity and Transparency at Every Step

We keep communication clear, open and jargon free, so you stay fully informed and in control.

Expertise

With decades of legal practice, we deliver the experienced representation your situation demands.

Ownership

Your case is handled by one fee earner from start to finish providing consistent continuity and a single point of contact throughout.

Founding Principle

Our founding solicitor, Ashleigh Harold launched the firm with one clear principle in mind: that clients deserve the standard of representation that she would want for herself. A solicitor who listens, is transparent and fights with absolute skill and dedication. Over years of working in high-pressure regulatory and investigative environments, Ashleigh saw how easily people can feel lost, overlooked or treated like a case number. She wanted to change that.

The firm is built around the level of care and commitment she would demand if she was in her clients’ shoes because when the stakes are high, nothing less is acceptable.
