Purpose This article sheds light on the legal services offered by antiviolence centers through a discursive practice-based analysis of women who have experienced domestic violence and the lawyers who volunteer in the center. Design/methodology/approach Using a practice-based framework, the article utilizes a case study of the first legal meeting between a lawyer and a woman who has experienced violence. The case study illustrates how the legal advisors' expertise is deployed in the use of "discursive practices" in dealing with women who have experienced domestic violence. Through a systematic analysis of the verbatim narrative, the case shows how the lawyer performs her legal help through expert "discursive practices" which are situated in recognition of the texture of practices experienced by women in the legal system. Findings The case study shows how a practice-based approach is able to account for lawyers' discursive and interactional knowledge in dealing with domestic violence. This expert doing and saying includes the ability to read the complexities of abusive situations, using "professional vision" to identify, highlight and codify clues and patterns of a partners' violent behavior; the mastery of "co-implication" with women to support the development of a narrative of the abuse as a crime recognizable both by the victim and the legal system. Originality/value The analysis shows that practice-based approaches to knowing and learning in investigating discourse practices can provide insights on practitioners' interactional expertise as well as the relevance of the service. While a close look at the actual practices illustrates the lawyer's interactional mechanisms, the crucial role of legal aid in the antiviolence center can be appreciated by contextualizing within the texture of practices that characterizes women's experiences with violence.
