Formerly of RadcliffesLeBrasseur, Simon is a Partner in our property litigation team, providing comprehensive advice on all aspects of contentious commercial real estate work.

Recognised as a leading expert in the London market, Simon has substantial rent review experience working for landlords and tenants both in and outside the capital. He advises in relation to rights of light, nuisance, possession claims, overage and emergency injunctions.

He was on the founding committee of the non-profit Dilapidations Association, which was created in 2017 to promote opportunities for mutual discussion and learning for all professionals involved in commercial disrepair and reinstatement disputes.
