William Tautz

  • Call: 2004
William Tautz


William practises principally in children’s family law, both public and private. Having come to the Bar as a mature person, William is regularly entrusted with cases of a complexity and sensitivity normally reserved for more senior counsel, including long fact-finding hearings and cases with a significant cultural, religious or international element. He was recently led in a case of fabricated illness acting for a parent, and he conducts appeals in both private and public law children’s proceedings. William also practises in mental health law, appearing before the Court of Protection and mental health review tribunals. He regularly represents individuals with severe mental health problems, including through the Official Solicitor.

In education law, William has experience of appeals in relation to admission and exclusion and special educational needs. William is committed to legal aid and the representation of individuals who cannot afford legal services. He is direct access qualified, and regularly acts pro bono.

As a sideline, William provides pre-publication legal advice to several national newspapers. William is happy to consider giving pro bono advice on defamation to charities and campaigning organisations prior to publication.

William’s practice reflects his deeply held views about the welfare and best interests of society’s most vulnerable individuals. Care proceedings, the Court of Protection, mental health and special educational needs are all areas encompassed within his expertise. His constructive, compassionate approach applies whether he is representing children, patients, parents and family members, or local authorities. William believes that fearless advocacy is not undermined by a compassionate approach but is in fact greatly strengthened by it. The very positive feedback he receives from both lay and professional clients supports this view.

William Tautz has a BA degree in psychology from Truman State University in the US. His former career was in managing mental health services in London and so he has a very strong lay understanding of related issues that informs his practice in all areas.

At the age of 33 he returned to education and obtained an LLB (Hons) degree from South Bank University, earning a first class degree and the Law Department’s Sweet & Maxwell Prize for outstanding student. In 2002 he won a £2,000 prize in The Times Law Awards.

After completing the Bar Vocational Course, he undertook pupillage at Garden Court Chambers. His experience also includes criminal law – with trials in both the crown and magistrates courts – and civil law.

William’s interest in family law stems from his commitment to his own children and his belief that decisions that relate to family life will have a profound and long-term impact not just on the individuals concerned but on society.


William is married and has five children aged between nine and 22 years. He practices meditation and yoga.
