HMCTS High Court guidance relating to the filing of documents

On 12 July HMCTS emailed legal professionals in the following terms:

Good Afternoon,
We are writing to inform that we are introducing an email naming convention and a document upload centre (DUC) to streamline the process of sending bundles to the court and improve document security. Please see attached for further details and guidance.
We would be grateful if you could circulate this information within your organisation to ensure your colleagues are made aware.

We attach that guidance below for sake of ease.
