He is not known to have ever been convicted of sexually assaulting a child, but a judge said he was “convinced that Studdert committed a historic sexual assault in England and Wales” as well. than in Poland, Denmark and Italy.
Evidence compiled by a law firm appointed to manage his estate revealed that Studdert was “likely” to have had sexual contact with children in Poland, where he had “close ties”, and had also traveled “a lot. With O’Carroll in Eastern Europe. .

But his executors took the High Court “because they rightly feared the estate could be the subject of claims from historical abuse survivors,” Chief Master Marsh said in a judgment.
Following a series of hearings between January 2019 and April, the court concluded “that there is a real possibility that the deceased committed a historic sexual assault here and abroad, and ordered the executors Studdert’s will not to distribute the remainder of his estate.
The court also ruled that these historic assaults “may have given rise to claims for personal injury against the deceased and therefore his estate”, although “no claims have been suggested and the (executors) are unaware of the identity of potential applicants ”.
Chief Master Marsh had previously ordered the executors to pay the “relatively small” sums Studdert left to his “Polish friends” and to contact the police and the Church of England to see if they had any further information. on the potential abuse of Studdert.
He also ordered them to “create dedicated websites” in English, Polish, Danish and Italian with details of Studdert’s date of death and criminal convictions, as well as to post the website on Twitter, Facebook and Wikipedia.
The judge concluded: “It remains to be seen what emerges from the steps taken by the (executors).
“It is clear, however, that a complete ban on the distribution of the estate should not remain in place indefinitely. ”
Chief Master Marsh added: “We can consider setting up a compensation system if this is justified. ”
