A bond is an insurance policy put in place to protect the person whom the deputyship is for.
Once you have been appointed as deputy by the Court of Protection, as part of the Court overseeing the deputyship they may ask one of the Court of Protection visitors to meet with you for an assurance visit.
Specifically the Court looked at whether the provisions were valid or not. If the OPG is unsure about a certain provision included in a Lasting Power of Attorney they can make an application to Court to ask a Judge to make a ruling.
For most people who are appointed either as an attorney or deputy, a difficulty can arise over a question of gifts and the authority to make them.
Gifts are part of everyday life and there are many reasons why someone would make a gift. If someone does lack capacity and has a deputy or attorney in place there are strict rules about what gifts can be made.
