Chambers UK 2024

"Jon guided and supported us through an incredibly difficult time in our lives. He is dedicated, kind and excellent at his job. In a time of confusion and stress, Jon was calm, dedicated and supportive. I would highly recommend him."

"My matters were dealt with by Mr Jonathan Jonas with sincerity and extreme sensitivity throughout my entire procedure. I felt that the attention Mr Jonas gave to my case was exceptional and am so relieved that he was available for me and my daughter."

Public Law children (Complex Care Proceedings)

"We sought legal support in relation to an initial child protection situation and while other solicitors we had reached out to either provided a run down of legal material otherwise available online or commented that solicitor involvement would only be necessary if matters were escalated by the local authority, Jon went well beyond that and provided what we really needed and with reasonable costs, listening carefully to the situation and providing guidance on how best to approach the matter based on his significant experience. This was immensely helpful in a situation that was very stressful for us."

Public Law children (s47 investigation/ Child Protection process)

"I wouldn’t hesitate to recommend Jon and team for the work they did in my relocation/child arrangements case. Jon’s approach is professional and diligent, but with a very human essence. He genuinely wants the best outcome for his client and the child(ren) involved. I’m truly grateful for the support he has given me throughout my litigation journey and the outcomes achieved for our case."

Private Law children (Child arrangements/ Relocation)

"Jonathan was great. He lead me through a very difficult process and I felt I was in safe and sympathetic yet pragmatic hands throughout. I felt he took all my concerns on board, listened without judgment gave clear advice and direction, was hugely reassuring and delivered a meticulously responsive service whilst minimising costs to a sensible level which is sadly all too often not the case in emotive Children Act matters. I would recommend him (and have done) without hesitation."
