The team will move from their current office in the Carfax to AFON House on the Worthing Road.
The new office will open in May 2023.
DMH Stallard has grown rapidly over recent years and now has seven offices in locations across Sussex, Surrey and London.
Richard Pollins, Managing Partner said:
“Since the first lockdown in 2020 we quickly adapted to new ways of working to ensure clients always receive the highest quality legal advice and support.
“Our town centre offices at AFON House are the latest seamless step in our commitment to our clients and on behalf of all my colleagues in Horsham, we are looking forward to business as usual from our new home.”
