The Diocesan charity was constituted by a Trust Deed dated 4 September 1934 registered under Charity Number 246871. 
On 11 September 1934 its Trustees were incorporated under the Charitable Trustees Incorporation Act 1872 in the name of Portsmouth Roman Catholic Diocesan Trustees Registered.
Following an Order of the Charity Commission dated 14 August 2002, this Trust Deed has been revoked and a new Trust Deed dated 5 December 2002, and a Deed of Variation dated 7 April 2004, has been put in place by the Bishop and the Trustees. 
On 20 July 2001, there was a Direction from Charity Commission, that all of the charities of which the Trustees are trustees except the Portsmouth Roman Catholic Priests’ Retirement Fund ( Registered Charity Number 1061194 ) and the charities holding real property in the Channel Islands, shall be treated as a single charity for the purposes of Registration and Accounting under the Charities Act 1993.
