Deputyships are rarely connected with inheritance disputes. For one thing, Deputies act to help and protect living people who have lost the mental capacity to make decisions. Inheritance disputes, by contrast, usually happen after someone’s death. Like Lasting Powers of Attorney – which are similar arrangements in many ways – Deputyships end as soon as the person being protected dies.
An unusual case from the end of last year, however, saw a professional Deputy seeking to reduce the risk of any disputes or claims occurring over the estate of the person they were protecting.
This blog examines the case and some of the interesting issues it raised. If you would like to know more about Deputyships in general before reading about this case, please take a look at our help guides on the subject.

The case of Bagguley v E [2019] EWCOP 49
The case concerned a 76-year-old man, referred to throughout as ‘E’, who was living with severe dementia. E’s condition meant that he did not have the mental capacity to make decisions for himself and, since 2014, he had been under the care of a Deputy appointed by the Court of Protection to manage his property and financial affairs. E’s Deputy was a solicitor named Richard Bagguley.
E had three adult children, referred to as D, P and A. However, there had been some doubts in the past over whether E was their biological father. Some DNA tests had already been carried out, one in 1991 following the suicide of the children’s mother, and another in 2002. The first test had been taken to determine whether E was the children’s father, the second had focused on how closely related the children were to each other. The tests had indicated that there was a high probability E was the father of D, P and A, but the results were not absolutely conclusive.
E’s health was deteriorating and Mr Bagguley thought that question marks over the children’s parentage could increase the risks of disputes arising over E’s estate when he died. He applied to the Court of Protection to allow a DNA sample to be taken from E so that a further paternity test could be conducted. Because of E’s lack of mental capacity, he could not provide the required consent, and Mr Bagguley wanted a ruling from the Court to determine whether making this decision for him would be in E’s best interests.

How often should I update my Will?
Life has a habit of changing dramatically when we least expect it. The further in advance we plan for something, the greater the potential for life to upset those plans.
Understanding the Probate Timeline
The term ‘probate’ is often used to refer to the period of winding up someone’s estate after their death. However, ‘probate’ can more specifically mean a document issued by the Probate Office.
