Written by “Should I sue?” is not one question. It is a sequence of questions about legal basis, evidence, time limits, remedy, defendant solvency, cost, enforcement, settlement and personal tolerance for risk. A claim may be legally arguable but still commercially irrational, emotionally costly or practically unenforceable.
Publication snapshot
- Do not issue a claim only because you are angry, right, or have been treated badly.
- Check legal basis, limitation, evidence, defendant identity, recovery prospects and costs before proceedings.
- ADR, complaints and negotiated settlement may be better than litigation in some disputes.
- Issuing a claim starts a process with deadlines, fees, procedural duties and possible costs consequences.
Why “Should I sue?” is the wrong first question
The better first question is: what useful outcome can this process realistically produce?
Litigation can determine legal rights, award money, order certain remedies, and create enforceable judgments. It cannot always deliver apology, vindication, emotional closure, speed, affordability or practical recovery. A person can win a judgment and still struggle to recover payment. A person can have a genuine grievance but no viable legal claim.
The working distinction
A strong grievance is not automatically a strong claim. A strong claim is not automatically worth issuing. A judgment is not automatically payment.
For litigants in person, the danger is often late realism. The weaknesses become clear only after court fees have been paid, evidence has been served, the other side has defended, and the process has already taken over months of life.
This guide is directed at ordinary civil claims in England and Wales. It does not cover Scotland, Northern Ireland, family proceedings, criminal proceedings, employment tribunal claims, immigration, public law, insolvency petitions or specialist statutory schemes except by way of general warning.
Is it a legal problem the court can solve?
Not every unfair event is a court claim. Before suing, identify the legal right that has allegedly been breached. That may be a contract, a duty of care, a statutory duty, a property right, a debt obligation, a professional duty, or another legally recognisable basis.
The court will not normally decide a case simply because one side behaved badly. The claimant must show a legal cause of action, a defendant who is legally responsible, a remedy the court can grant, and evidence supporting the claim.
Ask first
- What legal duty or obligation was breached?
- Who owed that duty?
- What loss, damage or remedy is claimed?
- What evidence proves each part?
- Can the court grant the outcome sought?
Warning signs
- the complaint is mainly about unfairness, tone or disrespect;
- the loss cannot be calculated or evidenced;
- the proposed defendant did not owe the relevant duty;
- the remedy sought is apology or accountability only;
- the claim depends on suspicion rather than evidence.
This does not mean non-legal issues do not matter. They may be better suited to negotiation, complaint procedures, ombudsman schemes, regulators, internal grievance routes or practical settlement.
What type of claim is it?
The claim type matters because it affects limitation, evidence, remedy, procedure, cost and risk. A breach of contract claim is not prepared in the same way as a personal injury claim. A professional negligence claim is not the same as a consumer complaint.
| Claim type | Core question | Typical evidence | Main warning |
|---|---|---|---|
| Breach of contract | What was agreed, and how was it breached? | Contract, terms, emails, invoices, payment records, loss calculation. | Terms, exclusions and limitation dates may change the analysis. |
| Debt | Is money legally due and unpaid? | Invoice, account statement, contract, admission, payment history. | The debtor’s ability to pay may matter as much as liability. |
| Negligence | Was there a duty of care, breach, causation and loss? | Expert evidence, documents, chronology, loss evidence. | Proving fault is not enough without causation and loss. |
| Personal injury | Was injury caused by another party’s fault? | Medical records, accident evidence, witness evidence, loss schedule. | Limitation, medical evidence, causation and costs rules need care. |
| Property or housing dispute | Who owed the duty and what remedy is available? | Tenancy, lease, title records, repair reports, photographs, correspondence. | Landlord, freeholder, managing agent and contractor may be different parties. |
Do not choose the claim category by instinct. Choose it by legal analysis. The wrong category can lead to the wrong defendant, wrong limitation date, wrong evidence and wrong remedy.
Do not plead the story first
Start with the legal elements. Then decide which facts and documents prove each element. A long narrative without legal structure is harder for the court to manage and easier for the defendant to attack.
Can you prove it?
Civil claims are usually decided on evidence, not certainty. The usual civil standard is whether a fact is more likely than not. But the claimant still needs admissible, relevant and organised evidence.
A claimant should test the case before issuing. What proves the agreement? What proves breach? What proves loss? What does the other side say? What documents undermine the claim? What witnesses are actually available?
Evidence to gather
- contracts, terms and invoices;
- emails, letters and messages;
- photographs, videos and records;
- witness names and short summaries;
- loss calculations and supporting receipts.
Evidence risks
- screenshots without context;
- missing documents or deleted messages;
- witnesses who are unwilling to attend;
- loss figures that are estimates only;
- expert issues without expert evidence.
Evidence should be preserved early. Do not edit, overwrite or selectively crop key material. If electronic evidence matters, preserve the original file, device record, email header, message thread or source data where possible.
The strength of a case is not measured by how much paper exists. It is measured by whether the evidence proves the issues the court must decide.
Are you in time?
Limitation is a gateway issue. If a claim is issued too late, the defendant may have a complete defence. Do not wait until the end of pre-action correspondence to check the deadline.
For many simple contract and debt claims, six years is often the starting assumption. For many personal injury claims, three years is often the starting assumption. But limitation can be altered by claim type, date of knowledge, children, capacity, concealment, mistake, deeds, specialist statutes and amendment rules.
Use the conservative date
If there is uncertainty, work from the earliest possible deadline until advice confirms otherwise. Negotiation, complaint handling, mediation and waiting for documents do not automatically stop time running.
Pre-action protocols matter, but they do not usually change the statutory limitation period. If time is close, a claimant may need urgent advice on protective issue, service, standstill agreement or settlement.
Limitation is not only a claimant issue
Defendants should also check limitation early. A limitation defence may shape the response, settlement strategy, evidence review and whether to invite discontinuance.
Can the defendant pay?
Winning is not the same as recovering. A judgment gives a right to enforce. It does not guarantee payment.
Before issuing, check whether the defendant is correctly identified, solvent, traceable, insured, within the jurisdiction and likely to have assets or income against which enforcement could realistically operate.
Recovery checks
- correct legal name and address;
- Companies House status where relevant;
- individual insolvency or company insolvency indicators;
- property, employment or trading activity;
- insurance cover or asset-backed defendant.
Recovery warnings
- uninsured individual with no clear assets;
- dissolved, dormant or insolvent company;
- defendant outside England and Wales;
- assets held by someone else;
- claim value lower than likely enforcement cost.
Sometimes it is rational to sue despite recovery risk, especially where limitation is close, insurance may respond, or a judgment has strategic value. But that should be a conscious decision, not an accidental discovery after judgment.
Costs and risk
Litigation costs include more than the court issue fee. A claimant may face hearing fees, application fees, expert costs, advice costs, document preparation, travel, time away from work and enforcement costs.
GOV.UK explains that court and tribunal fees are different from legal costs such as paying for a solicitor, and that the fee for claiming money you are owed depends on the amount claimed. Fee remission may be available for people with little or no savings and certain benefits or low income.
| Cost type | Why it matters | Question to ask |
|---|---|---|
| Court fees | Usually payable to issue and progress the claim. | Can you pay, or might fee remission apply? |
| Legal advice | May be needed for merits, limitation, drafting or hearing preparation. | Can you use fixed-fee or unbundled advice efficiently? |
| Expert evidence | May be necessary in technical, medical, valuation or professional negligence disputes. | Is the expert evidence proportionate and likely to be permitted? |
| Adverse costs | Risk depends on track, conduct, offers, applications and outcome. | What might you pay if you lose or behave unreasonably? |
| Enforcement | May be needed after judgment if the defendant does not pay. | Is enforcement realistic and proportionate? |
Small claims usually have more limited recoverable costs, but “small claim” does not mean “no risk”. Fast track, intermediate track and multi-track cases carry different cost consequences. Interim applications, unreasonable conduct, late evidence, failed settlement strategy and expert disputes can change the risk profile.
Do not price the case only by the amount claimed
A claim for £5,000 may be irrational if recovery is doubtful and expert evidence is needed. A claim for £5,000 may be rational if liability is documented, the defendant is solvent and settlement is realistic.
Alternatives to suing
Civil litigation should usually be treated as one option, not the automatic next step. Negotiation, mediation, ombudsman schemes, complaint procedures, chargeback, insurer engagement, trade-body complaints and structured payment plans may produce a better result.
The Civil Procedure Rules now expressly include promoting or using ADR within the overriding objective. The Pre-Action Conduct Practice Direction expects parties to exchange enough information to understand each other’s position, try to settle, consider ADR, and reduce the cost of resolving the dispute.
Negotiate directly
Useful where the facts are clear and the dispute may be resolved by payment, repair, apology, correction or staged performance.
Use mediation
Useful where the parties need help exploring settlement, narrowing issues or agreeing practical terms.
Use a complaint route
Useful where a business, public body, regulator, ombudsman or professional scheme has a relevant process.
Do not issue
Sometimes the rational answer is to preserve evidence, write off the loss, or resolve the dispute commercially.
ADR is not a clock-stopper. Limitation, pre-action protocol duties and urgent protective steps must still be managed.
Using legal help well
Legal advice does not have to mean handing over the entire case. A litigant in person may use targeted advice for merits, limitation, evidence, drafting, settlement, costs risk or hearing preparation.
A solicitor may help with correspondence, evidence, procedural steps, settlement and litigation management. A barrister may provide specialist advice, drafting and advocacy. In some cases, direct access barristers, fixed-fee consultations, pro bono services, law centres, advice agencies or McKenzie Friend support may be relevant.
Good questions for advice
- What are the legal elements of my claim?
- What evidence is missing?
- What is the limitation date?
- What costs exposure exists?
- Is settlement better than issuing?
Use advice efficiently
- send a short chronology;
- identify the documents that matter;
- state the outcome sought;
- ask focused questions;
- request written advice where the issue is important.
The purpose of advice is not simply reassurance. It should expose risk before money and time are committed.
Decision flow
Use this as a pre-issue risk filter. It is not a substitute for legal advice.
Define the legal claim
Identify the cause of action, legal duty, defendant and remedy. If those cannot be stated clearly, pause.
Check limitation
Calculate the earliest possible deadline and decide whether urgent protective steps are needed.
Test the evidence
Match each legal element to documents, witnesses, expert evidence or admissions.
Check recovery and cost
Ask whether the defendant can pay, whether enforcement is realistic, and whether the process is proportionate.
Compare alternatives
Consider negotiation, mediation, complaints, ombudsman routes, insurer engagement or not issuing.
Final checklist before issuing
Before issuing a claim, a litigant should be able to answer the following questions in writing.
Merits and proof
- What is the legal basis of the claim?
- Who is the correct defendant?
- What facts must be proved?
- What documents prove those facts?
- What is the strongest answer the defendant has?
Practicality and risk
- What is the limitation date?
- What is the realistic value of the claim?
- Can the defendant pay if judgment is obtained?
- What fees, costs and expert evidence may be needed?
- What settlement or ADR route has been considered?
Litigation may be necessary where the right is clear, the loss is serious, the defendant will not engage, limitation is approaching, or no effective alternative exists. But issuing should be a reasoned decision, not a reflex.
The Legal Lens point is simple: do not ask only whether you can sue. Ask whether you can prove the claim, issue in time, sue the right defendant, manage the costs, recover something useful, and withstand the process required to get there.
