Child Arrangements Order When a Parent Is Absent, in Prison or Has an Addiction

When a Parent Cannot Be Found

Relatives step in to care for children for reasons that are rarely straightforward — a parent disappears, goes to prison, or becomes unable to function because of addiction. Each scenario changes the procedural steps for getting a child arrangements order, but the underlying application is the same Form C100 filed in the Family Court.

If you cannot locate a parent to serve them with the court papers, you cannot simply skip them. The court requires that every respondent holding parental responsibility receives notice of the application. When a parent's address is unknown, you need to:

1. Document your search efforts — contact the parent's last known address and check with mutual family members
2. File Form C2 for directions — ask the court to permit substituted service or request a DWP address trace under Practice Direction 6C of the Family Procedure Rules
3. Apply for permission to proceed without service — if the trace fails, the court can dispense with service entirely and allow your application to proceed

Improvised service methods (sending a Facebook message, texting, posting on social media) are not valid without the court's explicit permission. Always apply for a formal direction first.

When a Parent Is in Prison

An incarcerated parent retains parental responsibility unless it has been restricted. They are entitled to be served with your application and may take part in the proceedings. Ask the court and prison how their participation can be arranged.

Service on a prisoner: Follow the court's directions about who arranges service. The papers should be sent to the parent at the prison through the prison governor's office. You need the correct prison address — the Prison Finder service on GOV.UK lists every establishment.

MIAM exemption: A respondent's imprisonment is not itself a MIAM exemption. The prison exemption applies when you, the prospective applicant, are in prison and cannot attend online or by video link. Otherwise, attend a MIAM or claim another exemption that applies to your circumstances.

Guardian's Allowance connection: If one parent has died, you may qualify if the surviving parent's custodial sentence had at least two years remaining when the other parent died — a tax-free weekly payment on top of Child Benefit.

When a Parent Has an Addiction

Parental addiction to drugs or alcohol is one of the most common reasons grandparents and relatives end up caring for children. The legal process does not change, but the evidence picture does.

If the parent's addiction creates safeguarding concerns — the child has witnessed substance misuse, been neglected, or been exposed to dangerous situations — you should file Form C1A (allegations of harm) alongside the C100. Cafcass will flag this in their safeguarding checks and the court may order drug or alcohol testing, or direct the local authority to produce a Section 7 welfare report.

The parent's addiction alone does not disqualify them from opposing your application. The court's decision rests on the child's welfare, assessed against the statutory welfare checklist. But a pattern of substance misuse that has led to social services involvement, police call-outs, or the child being placed with you as an emergency measure will be central to the Cafcass report and the judge's evaluation.

A practical reality: many relatives caring for a child because of a parent's addiction have been doing so informally for months or years. If the child has lived with you continuously for at least one year immediately before you apply, you qualify to file the C100 without needing the court's permission under Section 10(5B). If it has been less than a year, you will need to request permission and explain your connection with the child and the circumstances that brought them into your care.

Emergency Situations

If a child is in immediate danger — a parent turns up intoxicated demanding the child back, there is a threat of abduction, or the child has just arrived after a crisis — you can file an urgent or without-notice (ex parte) application. Contact the relevant Family Court and follow its published urgent-application contact procedure. Court staff will ask a judge or magistrate to decide when the hearing should take place.

After an order is made without notice, the application and order must be served on each respondent within 48 hours. The order must state the respondent's right to apply to vary or discharge it; follow the court's directions about any further hearing.

Moving Forward

These situations are stressful, and the bureaucratic process can feel overwhelming when you are already dealing with a family crisis. The Child Arrangements Order Process Guide covers the entire application from start to finish — including the permission assessment, MIAM, forms, Cafcass safeguarding checks, and hearings — written for relatives handling this without a solicitor.
