A lawyer who produced the radio version of The Hitch Hikers Guide to the Galaxy has pleaded guilty to attempting to pervert the course of justice.
Hyman faces a jail term
Bruce Hyman was caught on CCTV sending a fake legal document to his opponents in a child custody case.
The document was designed to show his client's opponent - the child's father - in a bad light.
Sentencing was adjourned at Taunton Crown Court on Monday, and Hyman was released on bail.
Simon Eades, the father in the custody case, said: "To be accused in court of something that the judge makes very plain could lead to a term of imprisonment, cannot be decribed. It's horrifying."
Hyman is a barrister, a radio and theatre producer, and script writer.
