PSO Application Process: How to Apply for a Prohibited Steps Order (Without Losing Your Cool)

The PSO application process is often triggered by a moment of pure panic. You’ve just found out your ex-partner is planning to move the children to the other side of the country, or perhaps they’ve decided to unilaterally change your son’s school. In these moments, “losing your cool” is a perfectly natural reaction—but in the eyes of the family court, a calm, strategic approach is your best weapon.

A Prohibited Steps Order (PSO) is a powerful tool used to prevent a parent from taking a specific action regarding a child’s upbringing. Whether you are worried about relocation, name changes, or medical decisions, understanding the PSO application process is the first step toward regaining control.

At A L Law, we help parents navigate this journey, ensuring that your parental responsibility is respected and your child’s stability is preserved.

Step 1: The MIAM (Mediation Information and Assessment Meeting)

Before you can officially start the PSO application process, the law usually requires you to attend a MIAM. This is a meeting with a mediator to see if the dispute can be resolved without a judge.

However, we know that some situations are too urgent for a chat over tea. You may be exempt from mediation if:

• You are applying for an emergency prohibited steps order due to an immediate risk of the child being removed from the UK.
• There is evidence of prohibited steps order domestic abuse.

If you aren’t exempt, the mediator will sign your court form, allowing you to proceed.

Step 2: Completing the C100 Form

The core of the PSO application process is the C100 form. This is often referred to as a prohibited steps order form when used for this specific purpose.

When filling out the c100 form prohibited steps order section, you must be incredibly specific. You aren’t just asking for a general “behave better” order; you are asking for a specific prohibition, such as: “The respondent is prohibited from removing the child from their current primary school.” At A L Law, we ensure your “Statement of Case” is punchy and factual, avoiding emotional rants that can sometimes cloud the legal issues.

Step 3: Paying the Court Fee

As of 2026, the court fee for prohibited steps order applications is £255. This is a mandatory government charge. If you are on a low income or receiving certain benefits, you may be eligible for “Help with Fees” to reduce or waive this cost.

Remember, this is just the application fee. If the matter is contested and requires multiple hearings, professional legal costs will also apply. As we discussed in “Prohibited Steps Order UK: How to Stop a Parent from Making Risky Decisions”, investing in expert representation early can often save you thousands in the long run by resolving the issue quickly.

Step 4: The Initial Hearing and CAFCASS

Once your application is lodged, the court will set a date for a First Hearing Dispute Resolution Appointment (FHDRA).

Before this hearing, an officer from CAFCASS (Children and Family Court Advisory and Support Service) will contact you and the other parent to conduct basic safeguarding checks. They will look into police and social services records to ensure the child is safe. Their initial “Safeguarding Letter” will play a huge role in the PSO application process, as it helps the Judge decide what immediate steps are needed.

Step 5: What Happens in an Emergency?

If the situation is a “red alert” emergency—for example, a parent is at the airport with the child—the PSO application process can be accelerated.

We can apply for an emergency prohibited steps order “Without Notice” (Ex-Parte). This means the Judge can grant the order on the same day without the other parent even knowing the hearing is happening. This provides an instant legal shield. Once the child is safe, a full hearing is scheduled so the other parent can give their side of the story.

Long-Term Stability and Child Arrangement Orders

A PSO is often a “defensive” move. To secure your child’s future permanently, you might need to combine it with a Child arrangement orders application. This sets out the long-term “Live With” and “Spend Time With” rules, ensuring everyone knows where they stand.
