In family law, divorce proceedings are generally a personal matter, initiated by one or both parties in the marriage. However, there are certain circumstances where someone else can file for divorce on a person’s behalf. This typically arises when the individual is incapacitated or unable to manage the process themselves, even if they are mentally sound. This article explores when it is legitimate for someone to file for divorce on behalf of another, the process, proof required, and the limits of a representative’s powers.
In family law, divorce proceedings are generally a personal matter, initiated by one or both parties in the marriage. However, there are certain circumstances where someone else can file for divorce on a person’s behalf. This typically arises when the individual is incapacitated or unable to manage the process themselves, even if they are mentally sound. This article explores when it is legitimate for someone to file for divorce on behalf of another, the process, proof required, and the limits of a representative’s powers.
When can someone file for divorce on another’s behalf?
The ability to file for divorce on someone’s behalf is not common and can only occur under very specific circumstances. In the UK, the general rule under family law is that divorce applications must be filed by the parties directly involved in the marriage. However, if one spouse cannot manage their own affairs because of incapacity or other legitimate reasons, a representative, or “litigation friend”, can step in to act on their behalf.
What are legitimate grounds for filing on someone’s behalf?
- Mental or physical incapacity: if a person lacks the mental capacity to initiate or manage the divorce process (e.g., due to advanced dementia or severe brain injury), a legal representative can act in their best interests.
- Emotional inability to cope: if the spouse is mentally of sound mind but is emotionally unable to cope with the process (e.g., severe depression, anxiety, or trauma), the court may allow a representative to act for them, provided they are given consent.
- Under the Mental Capacity Act 2005, if a person lacks the mental capacity to make decisions about divorce, the law provides a framework for the appointment of a litigation friend or representative.
Who can file for divorce on someone else’s behalf?
When a party cannot manage their own divorce proceedings, a representative, known as a “litigation friend,” can be appointed. This is most common when mental capacity is an issue. A litigation friend can be:
- A family member or trusted friend
- A solicitor or professional advocate
- A court-appointed deputy (under the Court of Protection)
A litigation friend must act in the best interests of the incapacitated person and must not have any conflict of interest.
What is the process for filing for divorce on someone’s behalf?
The process for filing for divorce on someone else’s behalf is similar to a standard divorce but involves additional steps to establish the representative’s legitimacy.
Step 1: Establish the need for a representative (litigation friend)
The court must be satisfied that the individual is incapable of managing their own affairs because of mental or physical incapacity or severe emotional distress. Evidence, such as medical reports or psychological assessments, may need to be submitted.
Step 2: Apply to become a litigation friend
To file for divorce on behalf of someone, the representative must apply to the court to be formally recognised as a “litigation friend.” This involves submitting a formal application, along with evidence that the individual cannot manage the process alone.
Step 3: Filing the divorce application
Once approved, the litigation friend can file a divorce application on behalf of the incapacitated spouse. The standard divorce process applies:
- Submit the completed application through the court system (now mostly online)
- Pay the court fee
What proof is needed that someone cannot file for divorce themselves?
The court requires clear and credible evidence to allow someone to file for divorce on another’s behalf. This evidence can include:
- Medical evidence: reports from doctors, psychiatrists, or psychologists confirming that the individual lacks the capacity to manage their own affairs.
- Statements from family members or carers: Supporting evidence from family members or carers explaining the individual’s condition and inability to cope.
- Court of Protection order: If the person has already been deemed incapable of making decisions under the Mental Capacity Act, this order can serve as evidence.
For other reasons of incapacity, evidence may need to show that the person’s mental health condition (e.g., depression or trauma) prevents them from initiating the divorce themselves.
What powers does the representative have?
If someone is permitted to apply for a divorce on another’s behalf, their role is to act solely in the best interests of the individual. The representative does not gain any broader power over the person’s life or finances unless separately authorised (e.g., through a Power of Attorney or Court of Protection order).
Specifically, a litigation friend can:
- Submit and manage divorce applications
- Respond to court queries
- Represent the incapacitated person’s wishes (if known)
- Engage with solicitors or mediators
The representative cannot:
- Make decisions that conflict with the best interests of the person
- Use the role to pursue their own interests (e.g., financial gain).

Can a divorce application be invalid or rejected?
If someone else files for divorce without proper authorisation, the application can be invalidated or rejected by the court. For example:
- If no evidence is provided to prove that the spouse is incapable of filing for themselves
- If the representative does not have the court’s formal approval as a litigation friend
- If the application was filed without the spouse’s knowledge or consent (where consent was required)
The court will scrutinise such applications carefully to ensure that they are legitimate and in line with the person’s best interests.
Could a divorce be finalised without a spouse knowing?
It is not possible for a third party to file for divorce on someone’s behalf and have the divorce finalised without the spouse’s knowledge. Divorce proceedings require the spouse being divorced (known as the respondent) to be formally notified of the divorce application. The respondent has the right to respond or contest the divorce.
If a third party, such as a parent or ex-partner, attempts to apply for divorce without the person’s knowledge, the court will reject the application. Any attempt to manipulate or falsify the process would constitute fraud and could have serious legal consequences.
The court ensures that no divorce can occur without both parties being aware, thereby safeguarding against misuse or fraudulent applications. In all cases, legal advice should be sought to navigate this complex and sensitive process.
