Welcome!

It is with great sadness that Triangle announces that one of our Directors, Ruth Marchant, has died following a long battle with cancer. She will be greatly missed as a Director, colleague and friend.

Ruth was a founding member of Triangle, over 20 years ago. Her contribution to how children can be supported to give evidence cannot be underestimated; she was responsible for a massive shift in how courts both receive and perceive the evidence of children. She was never afraid to question the status quo and to suggest new, innovative and compassionate ways of children having their voices heard in court proceedings. Her thinking and her work can only really be described as revolutionary.

She was a fierce believer in justice, children’s rights and disability rights, taking the view that even very young children can be competent communicators providing the ‘adults in the room get it right’; that the onus for this lies squarely on the adult’s shoulders.

Ruth steered Triangle for 20 years, driven by an overarching wish to do what was best and right for the children that came through our doors. She gave detailed thought to every aspect of this, from ‘how’ children were interviewed about their experiences in a way that could help them begin to recover from traumatic experiences, down to the minute details of ‘how’ they were asked about what drinks they would like.

If you would like to send your condolences, tributes or even memories of Ruth please use this link and we will pass onto the family.

Triangle's Careful Questioning of Children for Legal Purposes course enables professionals to respond safely and confidently when children or young people might be showing or telling that they are at risk, including careful initial questioning for potential legal purposes.

Our next CQC course on 23rd – 24th January in Brighton. Click here to find out more about what the course entails.

Triangle is an independent organisation enabling children to communicate about important things, especially in legal proceedings. Our vision is to reposition children and young people in society as competent communicators and active agents in their own lives. In the last 20 years we have worked with over 10,000 children and young people across the UK, through intermediary, advocacy, consultancy, specialist support, interviewing and expert opinion services.


Triangle provides skilled support for children and young people in different settings including legal proceedings and enables children's communication when it matters most, for example when children or young people’s evidence is required by the courts, when their views are needed to inform decisions about their lives, and when adults are trying to understand and respond to concerning behaviours.

Triangle is an independent organisation; not part of any government department, charity or voluntary agency.

We have a strong multidisciplinary team with a shared value base, skilled at communicating with children and young people with a wide range of needs.

We have particular expertise with very young children and those with complex communication needs arising from impairment, neglect or trauma. We aim to set the standard in the UK and beyond for careful and effective communication with children and young people.

We are regularly instructed in the most complex and high profile situations, and have been involved in many landmark developments in children’s evidence.

We also provide training and resources and contribute to national policy and guidance.
