Understanding the Threshold Document in Care Proceedings

Last updated: March 2026

Quick Answer

The threshold document is the written statement in which a local authority sets out the facts it asks the family court to find in order to satisfy the "threshold criteria" under section 31(2) of the Children Act 1989. It must establish that a child is suffering, or is likely to suffer, significant harm, and that this harm is attributable to the care given (or likely to be given) not being what a reasonable parent would provide. The threshold document is filed with the court at the start of care proceedings and forms the foundation of the local authority's entire case. Parents have the right — and the responsibility — to respond to every allegation it contains.


Introduction

If you are a parent involved in care proceedings, the threshold document may be one of the most difficult things you ever read. It will contain allegations about your parenting, your home environment, and the harm the local authority says your child has suffered or is at risk of suffering. It can feel deeply personal, unfair, and overwhelming.

But the threshold document is not a judgment. It is a starting point — the local authority's case as it stands at the date of issue. You have every right to challenge it, and understanding how it works is the first step towards doing so effectively.

This guide explains what the threshold document is, how it fits into the legal framework, and how you can respond to it. It is written primarily for parents, but will also be useful to family members, McKenzie Friends, and anyone supporting a parent through care proceedings.


The threshold criteria are found in section 31(2) of the Children Act 1989. They provide the gateway that a local authority must pass through before the court can make a care order or supervision order. The section states:

A court may only make a care order or supervision order if it is satisfied —

(a) that the child concerned is suffering, or is likely to suffer, significant harm; and

(b) that the harm, or likelihood of harm, is attributable to —

(i) the care given to the child, or likely to be given to him if the order were not made, not being what it would be reasonable to expect a parent to give to him; or

(ii) the child's being beyond parental control.

This is a two-part test. The local authority must prove both limbs — significant harm and a causal connection to the standard of parenting. If the threshold is not crossed, the court cannot make a care order, regardless of how concerned professionals may be.

What Is "Significant Harm"?

"Harm" is defined in section 31(9) of the Children Act 1989 as ill-treatment or the impairment of health or development, including impairment suffered from seeing or hearing the ill-treatment of another. The Adoption and Children Act 2002 extended this to include witnessing domestic abuse.

"Significant" means noteworthy or important. The court must compare the child's health or development with what could reasonably be expected of a similar child (section 31(10)). This comparison is contextual — it takes into account the child's individual characteristics, including any disabilities or special needs.

The categories of harm commonly relied upon in threshold documents include:

CategoryExamples
Physical harmInjuries, neglect of medical needs, exposure to dangerous environments
Emotional harmWitnessing domestic abuse, parental mental health impacting on the child, hostility or rejection
Sexual harmSexual abuse, exposure to sexual behaviour or material
NeglectFailure to provide adequate food, clothing, shelter, supervision, or stimulation
Likelihood of future harmBased on past behaviour, unresolved risk factors, or patterns of harm to other children

The "Relevant Date"

The threshold criteria must be assessed as at the date of the local authority's intervention — not the date of the hearing. This was established by the House of Lords in Re M (A Minor) (Care Orders: Threshold Conditions) [1994] 2 AC 424. The relevant date is usually the date the application was issued, or the date protective measures were first taken (such as the removal of the child under an emergency protection order or police powers of protection).

This matters because even if a parent has made significant improvements since proceedings began, the court must first decide whether the threshold was crossed at the point the local authority intervened. Improvements in parenting are relevant to the welfare stage — what order, if any, is in the child's best interests — but they do not retrospectively remove the threshold.


What Does a Threshold Document Look Like?

A threshold document is typically structured as a schedule of findings. It lists, in numbered paragraphs, each factual allegation the local authority asks the court to find proved. It will usually:

  1. Identify the child and the relevant date
  2. State the overarching harm — for example, "The child is suffering, and is likely to suffer, significant harm in the form of emotional harm and neglect"
  3. Set out the attributable factors — for example, "The harm is attributable to the care given to the child not being what it would be reasonable to expect a parent to give"
  4. List specific factual allegations under numbered paragraphs — these are the individual findings sought

Example Structure

A threshold document might be structured as follows (this is a simplified illustration, not based on any real case):

Schedule of Findings Sought

The local authority seeks findings that Child A, born [date], is suffering, and is likely to suffer, significant harm, namely emotional harm and neglect. The harm is attributable to the care given to the child not being what it would be reasonable to expect a parent to give, in that:

  1. The mother has a history of problematic substance use which has impacted upon her ability to provide consistent care...
  2. On [date], the child was found unsupervised at [location]...
  3. The child has missed [number] medical appointments since [date]...
  4. The child has witnessed domestic abuse between the mother and her partner on at least [number] occasions...

Each paragraph must be specific and factual. Vague or generalised allegations — "the mother is a poor parent" — are inadequate. The court expects precision: dates, times, locations, and the source of the information relied upon.


How to Respond to the Threshold Document

Responding to the threshold document is one of the most important tasks your solicitor will undertake on your behalf. The response should address every allegation — not just the ones you disagree with.

The Three Responses

For each allegation, you have three options:

ResponseWhat It Means
AdmittedYou accept the factual allegation is true
DeniedYou dispute the factual allegation and will require the local authority to prove it
Not admitted / qualifiedYou accept part of the allegation but dispute the detail, context, or characterisation

Practical Guidance for Parents

  1. Read the threshold document carefully with your solicitor — make sure you understand every allegation before responding
  2. Be honest — admitting facts that are true, whilst challenging those that are not, is far more effective than blanket denial. Judges are experienced in assessing credibility, and a measured, honest response carries weight
  3. Provide context — if an allegation is technically true but misleading without context, say so. For example, "It is admitted that the child missed three medical appointments. The mother was unwell on those dates and rescheduled each appointment within the following week"
  4. Challenge the characterisation, not just the facts — sometimes the facts are not in dispute, but the way they are presented is. A single incident may be described as part of a pattern when it was, in fact, isolated
  5. Consider the "attributable to" element — even if harm occurred, it may not be attributable to your parenting. For example, a child's emotional distress may be caused by the proceedings themselves, by a school environment, or by factors outside your control

When to File Your Response

Your solicitor should file the response to the threshold document within the timescale directed by the court — usually by the Case Management Hearing or shortly afterwards. Filing late, or not at all, can have serious consequences. The court may treat unresponded allegations as admitted, or may draw adverse inferences from your failure to engage.


Threshold and the Welfare Stage

It is essential to understand that crossing the threshold is only the first step. Even if the court finds that the threshold criteria are met, it does not follow that a care order will be made.

At the welfare stage, the court must apply the welfare checklist in section 1(3) of the Children Act 1989 and consider all the options available to it, including:

  • Making no order at all
  • Making a supervision order
  • Making a child arrangements order (placing the child with a family member)
  • Making a special guardianship order
  • Making a care order (with a plan for fostering, kinship care, or adoption)

The court must apply the no order principle (section 1(5)) — it should not make an order unless doing so would be better for the child than making no order.

This means that even if you accept or cannot successfully challenge the threshold, you still have a vital role to play in the welfare stage. Your evidence about the changes you have made, the support available to you, and your proposals for the child's future is critically important.


Common Issues with Threshold Documents

Overly Broad Allegations

Some threshold documents contain vague or generalised allegations that do not identify specific incidents. The court in Re A (Application for Care and Placement Orders: Local Authority Failings) [2015] EWFC 11 criticised this practice. If you believe an allegation is too vague to respond to, your solicitor should raise this with the court and ask the local authority to particularise its case.

Historical Allegations

The threshold document may include allegations about events that occurred years ago, or about the care of older children. Whilst past behaviour can be relevant to the assessment of future risk, the court should consider whether circumstances have changed. The Supreme Court in Re J (Children) [2013] UKSC 9 confirmed that historical findings must be assessed in their proper context.

Allegations Based on Hearsay

Much of the evidence in care proceedings is hearsay — reports from social workers about what others have said, referrals from schools, or records of conversations. Hearsay is admissible in family proceedings under the Children (Admissibility of Hearsay Evidence) Order 1993, but the court must assess the weight to be given to it. If a threshold allegation rests solely on hearsay evidence from an unidentified source, your solicitor should challenge its reliability.


Organising Your Threshold Response in the Bundle

Your response to the threshold document will form a key part of the court bundle. It should be:

  • Filed in Section B of the bundle (statements and affidavits)
  • Cross-referenced to the threshold document paragraph by paragraph
  • Supported by evidence — if you deny an allegation, identify the documents in the bundle that support your position
  • Paginated consistently with the rest of the bundle

A well-organised response helps the judge prepare for the hearing and demonstrates that you are engaging seriously with the proceedings.

Frequently Asked Questions

What happens if I do not respond to the threshold document?

If you do not file a response, the court may treat the allegations as admitted. This means the local authority would not need to prove its case at a contested hearing, and the court would move straight to the welfare stage on the basis that the threshold is crossed. Always file a response, even if only to say which allegations you admit and which you deny.

Can the threshold document be amended during proceedings?

Yes. The local authority can seek permission to amend the threshold document during proceedings — for example, to add new allegations or to remove allegations that are no longer pursued. Any amendment must be approved by the court, and you will have the opportunity to respond to any new allegations.

What standard of proof applies?

The standard of proof in care proceedings is the balance of probabilities — the same standard as in all civil proceedings. The local authority must prove that each allegation is more likely than not to have occurred. The Supreme Court confirmed in Re B (Children) [2008] UKHL 35 that there is no heightened standard for serious allegations; the more serious the allegation, the more cogent the evidence needed to prove it on the balance of probabilities, but the standard itself does not change.

Can I agree the threshold without admitting everything?

Yes. It is common for threshold to be agreed on a negotiated basis. This means the parties agree on a set of findings that are sufficient to cross the threshold, without the need for a contested fact-finding hearing. Agreed threshold wording is often more measured than the local authority's original document. Your solicitor can negotiate on your behalf.

What if the threshold is not met?

If the court finds that the threshold criteria are not satisfied, it cannot make a care order or supervision order. The proceedings will be dismissed, and the child will remain in (or be returned to) the care of their parents. However, this does not prevent the local authority from providing support on a voluntary basis under section 17 of the Children Act 1989, or from issuing fresh proceedings if new concerns arise.

Does the threshold document cover all the children in the family?

If proceedings concern more than one child, the threshold document may contain a single schedule covering all children, or separate schedules for each child. The threshold must be established in respect of each individual child — findings about one child do not automatically satisfy the threshold for another, although they may be relevant evidence.
