The Court of Protection in the case of Re MLJ 
EWCOP63 considered that a relative is usually best placed to know about thefinances of the person lacking capacity ('P').But it gave examples of when a family deputy would not be appointed asfollows :(a)where the proposed deputy hasphysically, emotionally or financially abused P;(b) where there is a need to
investigate dealings with P's assets prior to the matter being brought to the
court's attention, and the proposed deputy's conduct is the subject of that
investigation;(c) there is an actual conflictof interests, rather than simply a potential conflict;(d) the proposed deputy has anunsatisfactory track record in managing his or her own financial affairs;(e) there is ongoing friction
between various family members, which is likely to interfere with the properadministration of P's affairs; and(f) there is a need to ensure
that P is free from undue influence, particularly the influence exerted by theperson who is seeking to be appointed as deputy. ’
In this case P’s daughter had applied to the Court to bejoined as a deputy with P’s son.Howevershe had an unsatisfactory track record of managing her own affairs to include a conviction for
shoplifting, a caution for common assault and the failure of a business she had
set up. She had also been banned fromP’s care home.
This case involves an application for an additional Deputy to be added and act jointly with the existing Deputy for the Patient’s (‘P’) property and affairs.
