Anonymising Child Arrangements Order Applications – UK GDPR-compliant anonymisation per Children Act 1989
A C100 application for a Child Arrangements Order is an application under Children Act 1989 s.8 naming the applicant, respondent, and child. The Children and Families Act 2014 requires MIAM attendance before issue; Cafcass handles around 145,000 cases per year. anonym.legal pseudonymises those identifiers while preserving proposed arrangements, welfare concerns, and contact schedules.
When this applies
This task applies when a C100 application and position statements are shared with a mediator assessing MIAM compliance under Children and Families Act 2014 s.10, a jointly-instructed psychologist, or a reviewing solicitor, and those recipients require the s.1 welfare and contact narrative but not the parties' personal identities.
How anonym.legal handles it
- Upload the C100 form and any accompanying position statements or supporting documents.
- The engine identifies the child, applicant, respondent, and any named third-party family members across all documents.
- Each individual receives a unique, consistent pseudonym; proposed contact arrangements, holiday schedules, and welfare concerns are preserved in clear text.
- School names and GP details embedded in the application are pseudonymised where they identify specific individuals.
- A reversible mapping table is produced with UK data residency.
- Release the pseudonymised documents to the mediator or expert; restore real identities before court filing.
What you provide
- C100 application form
- Position statements from both parties
- Any MIAM exemption evidence or mediator's certification
Limitations & cautions
- The court copy of the C100 must bear the parties' real names; the pseudonymised version is for pre-proceedings use only.
- Where the application involves domestic abuse allegations, Practice Direction 12J FPR applies and the non-molestation order workflow may be more appropriate to manage sensitive address information.
- anonym.legal does not assess the merits of proposed child arrangements or apply the CA 1989 s.1 welfare checklist — those are matters for the court.
FAQ
Can I use the pseudonymised C100 in MIAM mediation sessions?
Yes, subject to your mediator confirming that a pseudonymised version satisfies their procedural requirements. Many mediators work from position statements rather than the court form itself.
Are school names treated as personal data in the application?
School names alone are not personal data, but a named school combined with a named child and address can amount to a combination that identifies the child. The engine treats such combinations as indirect identifiers and pseudonymises them.
Does the tool handle C100 applications submitted through the Online Family Court?
Yes. PDFs or DOCX exports of applications originally submitted online are processed identically to paper forms.
What if both parties have submitted separate position statements?
Upload both position statements in the same batch. Each party's personal data receives consistent pseudonyms across both documents, preserving the adversarial structure of the positions.
What data-minimisation risk applies to sharing C100 applications externally?
Children's personal data is Article 9 special-category data under UK GDPR. UK GDPR fines can reach up to £17.5 million or 4% of global annual turnover under Data Protection Act 2018 s.157. Among the roughly 248,000 family cases started in England and Wales in 2023 (MoJ Family Court Statistics), C100 applications represent a high volume of special-category data in circulation. Pseudonymising before sharing with mediators or experts addresses this risk.
