Zoë Saunders and Lucy Reed KC discuss the recently published guidance from the Family Justice Council: Responding to a child’s unexplained reluctance, resistance or refusal to spend time with a parent and allegations of alienating behaviour (https://www.judiciary.uk/related-offices-and-bodies/advisory-bodies/family-justice-council/resources-and-guidance/parental-alienation/). Zoë and Lucy summarise and explain the approach mandated by the guidance, and consider what practical difference it may make, for parents accused of alienating behaviours for those who wish to raise it as an issue, and for those representing the parties or the children in such cases. Discussion points include the co-occurrence of allegations of domestic abuse with allegations of alienating behaviour, the voice of the child and the role of experts.
