The Senior Courts Costs Office (SCCO) has earlier this week issued revised guidance on filing supporting papers for Court of Protection bills, coming into effect on 20 April 2026. These updates aim to streamline the assessment process and improve efficiency for both practitioners and Costs Officers.

The SCCO continues to support two methods for submitting supporting documents: digital bundles provided via the Document Upload Centre (DUC) and physical files of papers sent in the post or DX. A summary of the latest guidance is set out below.

1) Digital Bundles via the Document Upload Centre (DUC)

The Document Upload Centre (DUC) allows users to submit supporting papers electronically and is the SCCO’s preferred method, provided submissions follow the required format.

It is important to note:

• The DUC is only for supporting documents
• Key documents, including the bill of costs, N258B and court orders, must still be filed via CE-File in the usual way
• To access the DUC, users must request a link by emailing the SCCO

In terms of formatting, bundles must be in PDF format only. File names should include the SCCO reference number, the Protected Party’s surname, and the billing period or case type (for example, statutory will or property sale). The SCCO also find it helpful if an indication of the bill type is included within the file name, such as general management with the relevant period dates, so it is recommended that this is included.

Where possible, a single bundle should be submitted. If multiple files are necessary, these should be clearly labelled with the relevant date ranges rather than uploading individual documents separately.

Documents must be arranged in chronological order (oldest first), with key documents placed at the beginning of the bundle. These include:

• The OPG102 and OPG105
• Client care letter
• Disbursement evidence
• Counsel fee invoices

The level of detail within documents remains important. Emails and file notes should clearly show dates and times, with correspondence identifying both sender and recipient. File and attendance notes must also record the fee earner completing the work and the time claimed.

To assist Costs Officers in locating documents quickly, the SCCO recommend:

• Including a detailed index or bookmarks with clear dates and descriptions so items can be easily identified and cross-referenced against the bill of costs
• Adding hyperlinks to documents where possible
• Avoiding duplication of documents or email chains

In terms of timing:

• For existing cases: upload at the same time as filing the bill (once the SCCO reference number is available)
• For new cases: upload after receiving confirmation of the SCCO reference number (e.g. SC-2025-COP-001234)

2) Physical Paper Filing

Firms can still submit hard copy bundles by post. While digital filing is encouraged, it is not mandatory.

If submitting papers physically, they should be sent to:

Senior Courts Costs Office
Thomas More Building
Royal Courts of Justice
Strand
London
WC2A 2LL
DX: 44454 Strand

Many of the same principles apply to paper bundles as to electronic ones. Files should be clearly labelled with the SCCO reference number, the Protected Party’s name and the billing period or case type, and documents should be organised in chronological order.

Key documents should be placed at the front of the bundle (or the first bundle if multiple are submitted), including:

• The OPG102 and OPG105
• Client care letter
• Disbursement evidence
• Counsel fee invoices
• A copy of the e-filing acceptance notice, including return details
• Where multiple boxes or bundles are required:
• Label them sequentially (e.g. Box 1 of 2)
• Arrange documents chronologically across all boxes and bundles
• In terms of timing:
• Papers should be sent as soon as possible after CE-File acceptance
• They must be submitted within 28 days

Mandatory Filing Notification

Each time a bill is submitted via CE-File, you must clearly state how you intend to file supporting documents. This should be included in the “filing comments” by confirming either ‘paper’ or ‘DUC’. Failure to include this information may result in the filing being rejected.

Final Thoughts

These updates from the SCCO reflect a continued move toward digital efficiency while still accommodating traditional filing methods.

For practitioners, the key takeaway is simple: clarity, organisation, and compliance with formatting rules are essential. Adopting the DUC where possible, and doing so correctly, will help avoid delays and ensure a smoother assessment process, particularly given the continued delays and significant turnaround time for receipt of assessed bills, which remains in excess of a year at present.
