In the 1970s, when a heterosexual couple divorced, courts almost always awarded child custody to the mother, except in one scenario: when the mother had come out as a lesbian.

Professor Susan Golombok was determined to challenge these prejudices and to shine a light on the realities of same-sex parenting. She began studying a range of different family structures to build up a body of evidence which, over the course of her life, has had a tangible impact on everyday families around the world

In this episode, Alisha is in conversation with Susan about the influence and breadth of her work, from broadening societal perceptions to changing laws. We also hear from a couple who took part in the research and learn why it was so important to them, and the legacy it has left for families everywhere.
