Co-parenting with a narcissist: safety, children and the law
Co-parenting with a narcissist is a phrase, not a diagnosis: only a qualified mental health professional can diagnose a personality disorder[1]. The law looks at behaviour: controlling or coercive behaviour is domestic abuse[2], and there is support, a MIAM exemption[3] and protection from the courts.

01/ The word
What "narcissist" means, and what it does not
Narcissistic personality disorder is one of the types of personality disorder psychiatrists recognise[1]. The NHS says the way personality disorders are diagnosed is changing, and that a mental health professional explains what a diagnosis means[6]. Mind says only a mental health professional experienced in diagnosis, such as a psychiatrist or psychologist, can diagnose one; a GP cannot[1].
So this page does not ask whether the other parent "is" a narcissist. What matters to the family court and to Cafcass is what has happened and its effect on the children[7][8].
While facts are disputed and the court has not decided them, Cafcass itself describes people as the "alleged" or "reported" victim or perpetrator[9].
02/ Conflict or abuse
High conflict or domestic abuse?
Some arguing between parents is normal, but frequent, intense and poorly resolved conflict can harm children's mental health[10]. Cafcass separates harmful conflict from domestic abuse[7]. Its guide quotes a definition of high-conflict separation in which power is balanced, with neither parent particularly afraid[7].
Domestic abuse is different: in law it includes controlling or coercive behaviour, economic abuse and psychological or emotional abuse, and it can be a single incident or a pattern[2]. GOV.UK lists gaslighting, threats, intimidation and online abuse among its forms, and says it is never the victim's fault[5].
- Controlling behaviour: acts designed to make someone dependent, such as isolating them from support, taking their resources or regulating their everyday life[11].
- Coercive behaviour: threats, humiliation, intimidation or other abuse used to harm, punish or frighten[11].
- A criminal offence: repeated or continuous controlling or coercive behaviour towards a former partner or co-parent that has a serious effect, such as fear of violence or serious alarm or distress[12].
Cafcass says controlling behaviour can continue after separation, sometimes through the courts[9]. If you are frightened, that matters: see domestic abuse support. The support lines are at the end of this page.
03/ Communication
Keeping contact low, written and about the children
Cafcass says communicating positively, or even just neutrally, can make a big difference to conflict and to its impact on your child[13]. Its tips include[13]:
- agree rules for handovers, and agree to stop and pick up another time if a conversation breaks down[13];
- never use your child to pass messages[13];
- think about the best way to communicate, because texts and emails are easily misread[13];
- do not question your child about the other home or ask them to report back[13].
Parallel parenting
Where direct contact between parents keeps fuelling conflict, one approach described in research is parallel parenting: each parent stays involved, but contact between the parents is kept to a minimum[14]. See parallel parenting. Cafcass says children are okay with different rules in different homes unless they are at risk of harm[13].
Cafcass's online Our Child's Plan lets one parent send proposals for the other to accept or answer with proposals of their own[15]. Where there has been domestic abuse, the NSPCC suggests a co-parenting app so that communication stays focused on the child and to a minimum[16].
04/ Records
Keeping a record of what happens
If you may need to tell a court about harm, Form C1A asks for the nature and frequency of the abuse, approximate dates or the period it went on for, what happened, and whether you sought help from the police, a GP, social services or anyone else[17].
Evidence of domestic abuse for a MIAM exemption comes in listed forms, such as a protective injunction, a letter from a health professional, an independent domestic violence adviser or a domestic abuse charity, or evidence of financial abuse[18].
If you do not want the other parent to know your address, you leave your contact details off the form and use Form C8 instead[17].
05/ Your children
Protecting the children
Children pick up on emotions during a separation and can feel caught in the middle[19]. Cafcass advises reassuring them that they are not to blame and keeping conflict away from them[19].
Where there is domestic abuse, the rules recognise that it harms children, including when they see or hear it[11]. A court's decisions about children are made on their welfare, which includes any harm they have suffered or are at risk of[8].
06/ Mediation
Is mediation an option?
At a MIAM the mediator sees you on your own[20] and must assess whether mediation is safe and suitable, taking into account coercive and controlling behaviour and emotional abuse. If it is not safe or suitable, they must not mediate[21].
They also consider whether you could disagree with the other parent without fear of intimidation, during or after a session[22]. Shuttle mediation, with you in separate rooms, does not necessarily make it safe[22]. See mediation with a narcissist and when mediation is not suitable for more.
With evidence of domestic abuse in one of the listed forms, you can claim an exemption and apply to court without a MIAM[3]. See MIAM exemptions.
07/ Court
If you need the family court
You apply for a child arrangements order on Form C100[23], and Form C1A goes with the application to tell the court about harm[17]. Before the first hearing Cafcass carries out safeguarding checks with the police and local authority and usually phones each of you[24].
The court presumes each parent's involvement is good for the child only if that parent can be involved without putting the child at risk of harm[25]. Where domestic abuse is raised, it must make sure any order protects the child and the parent they live with, and it must not expect you to take part in dispute resolution that is not safe[26].
- Special arrangements at court, such as waiting arrangements and how you enter and leave the building[26].
- Screens or a video link: where you say you are a victim of domestic abuse, the court must consider measures like these[27].
- No questioning in person by the other parent in the situations the law sets out; the court can appoint a lawyer to do it instead[28].
- A section 91(14) order stopping further applications without the court's permission, where applications could be used to continue abuse[29].
08/ Protection
Protective orders
A non-molestation order protects you from being harmed or threatened, and an occupation order decides who can live in the family home[4]. There is no fee to apply[4]. If you need protection immediately, you can ask for an emergency order without telling the other person first[30].
Legal aid may be available to protect yourself or a child from abuse, and for advice on children or finances after an abusive relationship[31].
09/ Looking after yourself
Looking after yourself
This is exhausting. You can refer yourself to NHS talking therapies for problems such as anxiety and depression without seeing a GP, if you are registered with one[32]. The grief of a separation is real too: see the stages of grief in divorce.
