Sometimes, the court requires additional input from professional witnesses, such as psychologists or independent social workers. There are also witnesses who may have seen certain events unfold who can provide the court with essential evidence and back up your version of events. This guide aims to cover how witnesses are used in family law matters.
Who might be used to provide witness evidence in family court?
Witness evidence can play an important role in informing the court’s decisions on various matters such as child arrangements and domestic violence. Witnesses who provide evidence in family court can be broadly categorised into lay witnesses and expert witnesses.
Lay witnesses are individuals who have direct knowledge of the facts of the case. These can include:
- Family members: Parents, siblings, or other relatives who can provide insight into family dynamics, relationships, and the welfare of children.
- Friends and acquaintances: People who know the family well and can attest to behaviours, interactions, and the home environment.
- Neighbours: Those who might have observed relevant events or patterns of behaviour.
Expert witnesses are professionals who offer specialised knowledge and opinions that assist the court in understanding the issues. These can include:
- Social workers: provide reports and testimony on child welfare and the suitability of parental arrangements.
- Psychologists and psychiatrists: evaluate the mental health of parents or children and the impact of family dynamics on their well-being.
- Medical professionals: may provide evidence on physical injuries or medical conditions relevant to the case.
- Financial experts: in divorce financial proceedings, accountants or financial advisors might be called to provide clarity on financial matters and asset valuations.
The selection of witnesses depends on the specific issues at hand, with the court ensuring that their evidence is relevant, reliable, and adds value to the judicial process. Usually, as part of the proceedings, the court will list the witnesses they are prepared to hear from, and whose evidence is relevant to the dispute before it. Following this, the court will tell you or your solicitor to prepare and/or obtain witness statements in accordance with the timetable set out in the order, together with when they should be filed at court and served on the other party. Failure to provide the statement within the time specified may mean that the evidence may not be allowed.
Anyone can provide a witness statement and you should think about whether you have any witnesses from the above list who can support what you are saying. If someone has given a witness statement, they must be prepared to give evidence in court. This is so the other party can question them and challenge their evidence. Before asking your witness to provide a statement, you should ask them if they are willing to go to court.
How are witnesses used in family proceedings?
Witnesses are essential in presenting a full and accurate picture of the facts and issues in family law cases, aiding the court in reaching fair and just outcomes. The process for testing their evidence involves several key steps:
- During the hearing, the witness who provided a statement may be called to give oral evidence. The party who called the witness conducts the initial questioning (examination-in-chief) to expand on the written statement and highlight key points.
- After the examination-in-chief, the opposing party has the opportunity to cross-examine the witness. This process tests the credibility and reliability of the witness’s testimony by probing inconsistencies and challenging their observations or opinions.
- The party that called the witness can conduct a re-examination to clarify any issues raised during cross-examination and to reinforce the witness’s key points.
- The court assesses the credibility and relevance of each witness’s evidence. This includes considering the witness’s demeanour, consistency, and any potential biases. The weight given to a witness’s testimony can significantly influence the court’s decisions.

When would a witness/their evidence not be used?
There are several circumstances under which a witness or their evidence might not be used:
- Evidence must directly relate to the matters being decided, such as the welfare of a child or the financial arrangements in a divorce. If the witness’s evidence is deemed irrelevant to the issues at hand, the court may decide not to consider it.
- Hearsay evidence, which is information a witness has heard from someone else rather than directly experienced, is generally less reliable and may be excluded unless it falls under specific exceptions allowed by the law.
- If a witness is found to lack credibility because of previous dishonest behaviour, inconsistencies in their testimony, or clear biases, their evidence might be given little or no weight.
- If the witness’s evidence has not been properly submitted according to court rules and procedures (e.g., missing deadlines for submitting witness statements), it may be excluded.
- Evidence that is repetitive or duplicates what has already been presented might be excluded to avoid unnecessary repetition and to streamline the proceedings.
- For expert witnesses, if the court finds that the expert lacks the necessary qualifications or expertise, their evidence may not be admitted. Additionally, if the expert’s testimony is not sufficiently impartial or appears to be heavily biased in favour of one party, it may be disregarded.
- The court may exclude evidence if its potential to prejudice the case outweighs its probative value. For example, evidence that might unduly sway the court’s emotions without contributing significant factual information could be excluded.
- If a witness is unavailable to testify in court and their presence is deemed crucial for cross-examination, their written evidence might not be admitted.
Excluding unreliable, irrelevant, or procedurally improper evidence ensures that the court’s decisions are based on the most accurate information available.
Does witness evidence make much difference to a case?
In many circumstances, a witness who can enhance the strength of your case is limited. They may add nothing worthy of note, or, at worst, muddy the waters, causing focus to be lost. That is not to say that a good witness isn’t worth their weight in gold, their testimony can be crucial. But you should always try to objectively evaluate what they can add to your case before asking them to complete a witness statement, which will be scrutinised by the other side, and, more likely than not, be cross-examined.
