The PSU is a small independent charity that offers non-legal support to litigants in person, their family members and other supporters. The PSU's service is free, independent and confidential and the service is offered equally to anyone who asks. Requests vary from the very simple to the complex. The overall aim of the charity is to help litigants to better understand the court process. The PSU is based at the Bristol Civil and Family Court Centre. Students volunteer with the PSU and commit to a minimum of 20 hours over the academic year.
