Helping you succeed in tomorrow's world

A career focussing on liability spotting (including time spent in-house on secondments) means that I provide practical and commercial advice to enable clients to navigate risks, assess their impact and to reach a successful conclusion - whether that means the resolution of a dispute or practical recommendations at the end of an investigations.   I have a particular interest in decarbonisation and the increasing threat of ESG-related litigation against companies and their directors.

In all my work, I am supported by an excellent and dedicated team. And as a Diversity Champion within Osborne Clarke, I take an active role in promoting and improving our firm's culture so that our teams fulfil their potential and perform at the highest level.  I'm delighted when we can share the benefits we obtain from our diversity and inclusion programmes with our clients and collaborate on setting a better standard for all.

Jane Park-Weir is a very able, technical lawyer with a good understanding of legal issues. Further, she and her team are very easy and fun to work with."
