William Lacey

Call 2022

Construction & Engineering

William is developing a broad construction practice, spanning both “pure” construction and insurance-related litigation. His practice includes advising clients, drafting pleadings and adjudication documents, and representing litigants at interim and final hearings. He is able to advise on adjudication procedure and enforcement, standard form contracts, the Building Safety Act 2022, latent defects insurance, new home warranties, developer/builder insolvency, party wall disputes, subrogated recovery, and limitation periods. He accepts appropriate instructions on a direct access basis, which can be an efficient way for developers, builders, self-builders and construction professionals to obtain focussed legal advice and representation.

The claim settled before trial for a nominal sum.
  • Representing a homeowner at trial, in circumstances where the homeowner was accused of breaching a Party Wall Award in the course of a construction project. The case raised challenging issues of jurisdiction, limitation and declaratory relief.
