Questions from
solicitors we work with.
Do your experts complete COP3 forms for Court of Protection applications?
Yes. Our members are experienced in completing COP3 forms for deputyship and welfare applications. The form is prepared alongside the full CPR Part 35-compliant report, ensuring consistency and compliance with Practice Direction 9E.
Can your experts assess capacity for individuals with dementia?
Yes. Our consultants regularly assess individuals with cognitive impairments, including dementia. Assessments are tailored to the individual’s communication ability, with findings grounded in the functional test under the MCA 2005.
How do your experts address section 45a Mental Health Act in capacity reports?
Where relevant. Our reports identify interfaces between the MCA 2005 and section 45a Mental Health Act, particularly in cases involving restricted patients. The assessment clarifies the legal framework governing the individual’s decision-making.
Are remote capacity assessments acceptable for Court of Protection proceedings?
Yes, where appropriate. Secure video assessments are accepted by the Court of Protection for straightforward capacity determinations. For complex cases or where communication is significantly impaired, we recommend in-person assessment.
Do your experts respond to Part 35 questions from the opposing party?
Yes. Our members respond to Part 35 questions under CPR 35.6, liaising with instructing solicitors to ensure responses are proportionate and comply with the Civil Justice Council 2014 Guidance.
