Reaching a COT3 settlement through ACAS is usually the end of a workplace dispute, but only if the other side actually pays. When a respondent misses the agreed payment date and stops responding to chasing letters, you may need to take the matter further by asking the High Court to enforce what was agreed.
One of the most effective routes is a Writ of Control, which sends an enforcement officer to recover what you are owed. This guide walks through how enforcement of a COT3 works in England and Wales, which form you need to complete, what supporting information the court expects to see, and what happens once the writ has been issued. It is written for claimants who have already settled through ACAS and now simply want to get paid.
What this document is
A Writ of Control is a High Court order that authorises an enforcement officer to attend the debtor's premises and take control of goods up to the value of the debt, along with fees and interest. The goods can then be sold to satisfy the sum owed.
It is the High Court equivalent of a warrant of control used in the County Court, and it tends to be faster and more robust where the debtor has assets worth pursuing. In the context of an ACAS settlement, the COT3 is the binding written record of the terms the parties agreed through a conciliator.
If the paying party fails to honour those terms, the COT3 can be enforced in the civil courts in much the same way as a county court judgment. Because COT3 settlements are not automatically registered as court orders, a short application process is needed before enforcement officers can act.
Once the writ has been sealed by the court, enforcement agents have statutory powers to recover the sum due, subject to the usual protections for the debtor.
How to use this document
01
Confirm the settlement has been breached. Before applying to the court, check the COT3 carefully to confirm the payment deadline has passed and that no instalment plan or conditional clause is still running. Send a short written reminder to the respondent noting the overdue amount and giving a short window to pay. This creates a clear paper trail showing the default.
02
Gather your paperwork. You will need the signed COT3 itself, evidence of the amount outstanding, and any calculation of interest you intend to claim. If interest is being added, set out clearly how it has been worked out, including the rate applied and the period covered. Accurate figures here will save time later if the court queries anything.
03
Complete the application form. The relevant form for enforcing an ACAS settlement in the High Court by Writ of Control is Form N471A. Fill in the applicant and respondent details, the sum now owed, and any costs you are claiming. Include the statement of truth and the declaration relating to ACAS matters, and sign where required.
04
Submit the application to the court. File the completed N471A along with a copy of the COT3 and your interest calculation (if any). The application is sent to the High Court, and the court will decide whether to make the order permitting enforcement. There are separate court fees for issuing the writ itself, so check gov.uk for the current amount.
05
The writ is issued and enforcement begins. Once sealed, the Writ of Control is passed to a High Court Enforcement Officer (HCEO), who will give the debtor formal notice of enforcement before attending. The officer can then take control of goods up to the value owed. Sums recovered are paid through the enforcement officer back to you, less their fees.
Common questions
QIs a COT3 legally binding?
Yes. A COT3 is a legally binding contract between the parties, recorded by an ACAS conciliator. It prevents a tribunal claim being brought on the same matter and can be enforced through the civil courts if the agreed terms are not honoured. Because it is a contract, ordinary contractual remedies are available, but enforcement through a Writ of Control is usually the quickest route where money is owed.
QCan I enforce a COT3 in the County Court instead?
In many cases yes, and smaller sums are often pursued through a County Court warrant of control rather than a High Court writ. The High Court route tends to be chosen for larger sums or where the debtor is thought to have assets worth seizing. The right choice depends on the amount, the debtor's circumstances, and how quickly you need action taken.
QHow long does enforcement by Writ of Control take?
Timescales vary. Once the court issues the writ, the enforcement officer must give the debtor a notice of enforcement, usually at least seven clear days before attending. After that the officer can attend the premises to take control of goods. Straightforward cases can be resolved in a few weeks, but disputes, payment plans or a lack of assets can extend things considerably.
QDo I need a solicitor to apply?
No. The application can be made by the claimant directly, and the form is designed to be completed without legal representation. That said, enforcement decisions can have knock-on consequences, so some people prefer to talk through their options first. An experienced legal adviser can help you think through whether a Writ of Control is the right step based on what you describe.
QWhat if the debtor has no goods to seize?
If the enforcement officer attends and finds nothing of value, the writ may be returned unsatisfied. That does not wipe out the debt, but it does mean you may need to consider other routes, such as an attachment of earnings order, a third party debt order, or a charging order against property. Each has different requirements and success depends on the debtor's circumstances.
QCan I claim interest on the unpaid amount?
Often yes. If the COT3 itself provides for interest on late payment, you can rely on those terms. If it is silent, statutory interest may still be available under the Judgments Act or similar provisions, depending on the circumstances. You will need to show a clear calculation with the application, including the rate used and the period claimed, so the court can check the figures.
QWhat happens if the debtor disputes the amount?
A debtor can apply to the court to challenge enforcement, for example on the basis that payment has already been made or that the sum claimed is wrong. If that happens, enforcement may be paused while the court considers the objection. Keeping clear records of what has been paid, when, and any correspondence with the debtor makes disputes much easier to resolve.
