Our professional clerking staff can help you identify the right barrister for your case.

Lydia Seymour has a specialist pensions and employment law practice. She has been recognised by the legal directories as a leading junior since 2005 and is listed in both the employment and pensions categories.

Her practice includes all aspects of ‘black letter’ pensions law, including: de-risking, rectification, withdrawal arrangements in multi-employer schemes and trustee duties. Her clients include the Pensions Regulator, employers, trustees, trade unions and individuals.

She also acts in claims of professional negligence arising from actuarial and legal advice to pension schemes, including cases in which allegations of breach of duty have also been made in respect of professional or lay trustees.

Given the dual nature of her practice, Lydia has developed a particularly strong reputation in the areas of crossover between pensions and employment law, and she is instructed in many of the leading cases in this area, particularly those which raise issues of age or sex discrimination in relation to pension provision, TUPE and breach of trust and confidence.

She also has substantial experience of statutory schemes and advises regularly on issues relating to the Local Government Pension Scheme, the Teachers’ Pension Scheme, University Superannuation Scheme and the NHS Pension Scheme.

Lydia has wide experience of employment and discrimination cases at all levels, appearing regularly in complex and high profile discrimination matters. She is also regularly instructed in claims arising out of the termination of employment, particularly those raising bonus or restrictive covenant issues.

Lydia sat as a fee paid Employment Judge between 2005 and 2017.

Pensions & Trusts

Lydia acts and advises in a wide range of contentious and non-contentious pensions work including ‘black letter’ pensions law; issues relating to statutory schemes and claims at the interface of pensions and employment law.

She has acted and advised (both alone and with leading counsel) in High Court claims raising issues of scheme amendment (including estoppel and misrepresentation); de-risking (including Courage fetter issues and the pensions / employment crossover implications); equalisation and rectification. She has advised the Pensions Regulator on issues including scheme closures, section 75 debts, clearance statements and auto-enrolment.

She also has substantial experience of professional negligence actions relating to pensions, including advising and acting in claims involving allegations against actuaries and legal advisors, limitation problems and complex issues relating to loss. She is currently acting for a former lay trustee of a large defined benefit scheme accused of breach of trust in connection with losses to a pension scheme following the collapse of the principal employer.

Lydia is a leading practitioner in cases which raise issues of both pensions and employment law, and she is instructed in many of the leading cases in this area. These include age discrimination claims arising from scheme amendments and redundancy situations; TUPE – related pension issues, particularly those relating to the implications of the Proctor and Gamble decision; claims for breach of the implied term of trust and confidence arising from non-pensionability agreements and de-risking exercises, and sex discrimination and equal pay claims including calculation of the pension entitlements of part time workers.

In relation to statutory schemes, Lydia advises regularly on applications and responses in proceedings before the Pensions Ombudsman and has wide experience of the Local Government Pensions Scheme (LGPS), Teachers’ Pension Scheme (TPS), University Superannuation Scheme (USS) and the Principal Civil Services Pension Scheme (PCSPS). She has also advised trade unions on issues arising from the NHS Pension Scheme and Firefighters’ pensions.

Lydia is retained by a number of local authorities to give ongoing advice about issues arising under the LGPS, including: admission agreements; exit payments; guarantee bonds and TUPE problems. She also advises schools, colleges and other bodies on issues arising under the LGPS and TPS.
