The Standard of Proof that must be met before a marker is filed
CIFAS Principle 4 sets out the Standard of Proof that every filing organisation must satisfy before recording a marker on the National Fraud Database. This standard is the most important tool in any removal challenge, because it defines exactly what the institution was required to demonstrate before filing and what they must be able to justify now.
The standard is higher than mere suspicion but lower than the criminal standard of beyond reasonable doubt. In practice the Financial Ombudsman has confirmed the threshold must be genuinely robust given the serious consequences a marker carries for the individual.

Pillar 1: Reasonable grounds
The institution must have had reasonable grounds to believe that fraud or financial crime had been committed or attempted. An automated system flag, a suspicious transaction pattern, or a third party report are starting points, not conclusions. Reasonable grounds requires more than a system output. It requires a review of that output in the context of the individual's account history, circumstances, and any explanation they provided.

Pillar 2: Clear, relevant, and rigorous evidence
The evidence must be clear, relevant, and rigorous. Vague suspicion, circumstantial inference, or the fact that the account was flagged by a monitoring system is not sufficient. The institution should be able to identify the specific evidence it held at the time of filing, explain why that evidence is relevant to the conduct alleged, and confirm that the evidence was reviewed rather than simply generated by an algorithm.

Pillar 3: Recognised CIFAS case type
The conduct must fit a recognised CIFAS case type. Each case type has specific criteria. A Misuse of Facility marker requires evidence of deliberate misuse of an account or facility. A False Application marker requires evidence of a false representation in an application. The conduct must match the category used. Where it does not, the marker is inaccurate.

Pillar 4: Linked product decision
The institution must have withdrawn, rejected, or terminated a product as a direct result of the suspected fraud. The marker and the product decision must be connected. Where no product decision was made, or where the product decision was made for other reasons, this pillar of Principle 4 is not met.

Challenging the Standard of Proof
One of the most effective complaint arguments is challenging whether the institution actually met all four pillars before filing. Many institutions file markers based on automated system outputs without conducting the investigation needed to satisfy the evidential threshold.
Your complaint should specifically ask the institution to address each pillar in turn: what were the reasonable grounds, what specific evidence was clear, relevant, and rigorous, how does the conduct fit the case type used, and what product decision was made and when? When pressed on these questions, the evidence is often weaker than the marker implies.
The burden falls on the institution
You do not need to prove your innocence. The institution must prove the marker was lawfully filed. Asking them to justify each pillar of Principle 4 in writing puts them on notice that a generic refusal will not be sufficient.
