In line with ADASS guidance an IMCA should always be appointed for an adult who lacks capacity unless it will bring no additional benefits.
For adults who are subject to harm from family members/friends an IMCA should always be appointed at the start of the safeguarding process
For adults who have supportive families/friends but who may be “risk adverse” i.e. would push for a 24 hour care solution an IMCA should be appointed to avoid a potentially unlawful deprivation of liberty
For adults who have supportive families/friends who will support the adult in line with their wishes and the appointment of an IMCA may result in distress to the adult, it would be appropriate not to appoint as it will bring “no benefits”.
