There is no single best solicitor for every child arrangements case, so look for someone experienced in family law and disputes similar to yours. Check their experience, approach, fees and availability, and confirm that they are regulated by the Solicitors Regulation Authority (SRA); membership of Resolution may also indicate a constructive family-law approach. An initial consultation can help you assess whether they explain matters clearly and understand your child’s needs. If cost is a concern, check the latest legal aid guidance on GOV.UK or ask a regulated solicitor whether you may qualify.
