"We felt extremely lucky to have Jennifer represent us during an extremely stressful, complex and nuanced matter relating to the safety of our son and our needs to protect him from an ongoing risk of physical and emotional domestic abuse. Through her exhaustive knowledge of related law Jennifer provided us with clear advice on strategy, and strong, well contextualised recommendations at each stage on how to proceed."

A client, April 2023

"She has a strong instinct for when we needed more matter of fact input and at other times more motivational support, and we were particularly grateful for her ongoing support during our interactions with Cafcass; where her quick thinking, calm approach made all the difference. She was also highly approachable; making herself available at all crucial points during the matter. We believe the positive outcome from this matter was due, in no uncertain terms, to our appointing Jennifer."

A client, April 2023

"Jennifer Williamson came with exceptional recommendations and throughout a very long, traumatic and highly contested financial and children's act proceedings it became very apparent why. Having Jennifer's clarity of thought and attention to detail along with her incredibly calm and warm style at my side in the darkest moments, gave me the confidence to know I was in the safest of hands. They say the devil is in the detail, and Jennifer proved this time and time again. Thank you!"
