    Treaties covers the negotiation, drafting, interpretation and dispute resolution of international agreements between states, organisations or other recognised entities. A solicitor practising in this area helps clients assess how a treaty affects interests, drafts or reviews treaty texts, negotiates terms, and coordinates ratification or accession processes. They also advise on compliance, export controls, sanctions, and cross‑border obligations, and may represent clients in disputes arising from treaty interpretation before international bodies or domestic courts. The work shapes long‑term cross‑border obligations and relationships.
