Expert Advice
Clear, impartial advice, based on experience and sound professional judgment, is key to resolving disputes.
Our forensic engineers and architects provide a personal, partner-led service to deliver expert advice of the highest quality. Through our thorough, analytical approach, our experts will help you disentangle the technical issues so you can make informed, cost-effective decisions at each stage of the process.
In some cases, you may need early advice. WJM&P can provide concise, preliminary views based on limited information. This will enable you to assess quickly the strengths and weaknesses of your position. At the other end of the scale, our partners and experts provide advice for court cases and arbitrations.
Litigation Support
Whatever forum you choose, it is critical your expert understands their role as well as the technical issues. Key to this is the need for independence and duty to the tribunal. WJM&P’s testifying experts have the skills, experience and professionalism necessary to satisfy the demanding requirements of CPR Part 35.
As strong communicators and incisive thinkers, we narrow the issues during expert meetings. We provide clear explanations of technical matters for legal professionals through robust and detailed expert reports. You can be confident that the relevant issues will be carefully analysed and assessed. We regularly provide evidence for adjudications, the high court and other tribunals where our work stands up to robust scrutiny.
