Osbornes Law—Alex McMahon, Andrew Middlehurst & Harriet McMorrin

Homegrown hat-trick: Osbornes Law promotes three former trainees to partner

Osbornes Law has promoted three lawyers to its partnership, each of whom began their career at the firm.

Alex McMahon, Andrew Middlehurst and Harriet McMorrin have all been named partners in the latest round of promotions at the growing London law firm, highlighting Osbornes’ long-standing commitment to developing talent from within.

The trio have almost 40 years’ combined experience at Osbornes, having progressed from trainee or paralegal roles to partnership. Their promotions take the total number of partners at the firm to 34, including 20 women.

Alex McMahon is a public law specialist advising on housing, community care, welfare benefits, unlawful detention and asylum support, with a particular focus on judicial review claims.

Andrew Middlehurst specialises in personal injury, with particular expertise in cycling accident claims. He works closely with the London Cycling Campaign, for which Osbornes has been the legal partner for more than a decade.

Both Alex and Andrew joined Osbornes as paralegals before securing training contracts and qualifying with the firm.

Harriet McMorrin joined Osbornes as a trainee and qualified into the family team, where she has built a strong practice advising on issues arising from relationship breakdown, including cohabitation and nuptial agreements, financial matters and children cases.

Managing Partner Joanne Wescott said:“ Alex, Andrew and Harriet are excellent examples of what can happen when talented people are given the opportunity, support, and encouragement to build their careers within a firm. With almost 30% of our current partnership having started at Osbornes as trainees, we have a proven track record of attracting, nurturing, and retaining talent.

“Each of them has grown with Osbornes, contributed to their respective teams, and earned the trust and respect of colleagues and clients alike.

“They have more than earned their place around the partnership table. Their promotions are richly deserved and reflect not only their individual talent, but the strength of the culture we have built at Osbornes.”

Alongside the new partner appointments, four lawyers have been promoted to senior associate: Maeve Lucy, Blanca Diego, Jaro Bernat and Adele Pinkett. A further three lawyers — Eloise Mears, Erim Sheikh and Sarah Waller — have been promoted to associate.

Other promotions include partner Jenny Walsh becoming head of trusts following her return from maternity leave. Katie de Swarte, head of private client disputes, and Sam Collard, head of cycling claims, have become equity partners. Sam is another example of Osbornes’ commitment to developing talent from within, having joined the firm as a trainee.
