Physical incapacity
75.People who have suffered an injury resulting in a condition such as quadriplegia or a similar condition may lack the physical ability to sign the consent form although they have the capacity to consent. New paragraph 1(2) of Schedule 3 to the 1990 Act will allow a physically incapacitated person, who is unable to write and therefore give consent in writing, to direct another to sign on their behalf, in the presence of a witness.
