Drawing upon data from 100 criminal lawyers in England and Wales, the paper highlights the importance of pre-interview evidence disclosure for lawyers advising suspects at the police station.

Presently, the police in England and Wales disclose their evidence at different points during the arrest and detention of a suspect. While the courts have not objected to this, past field research suggests that lawyers can only advise their clients accurately when the police disclose their evidence before the police interview. To examine this from a law/psychology perspective, we recruited 100 criminal defence lawyers to participate in an online study. Lawyers read fictional scenarios and provided custodial legal advice to a hypothetical client (Christopher) when given either pre-interview disclosure or disclosure at various points during the police interview (early, gradually or late). Lawyers given pre-interview disclosure provided considerably more informed legal advice compared to those who were only provided with disclosure during the hypothetical police interview. Using an interdisciplinary approach, this article provides further evidence that pre-interview disclosure is essential for lawyers to deliver case-specific legal advice to suspects.
