The assumption that leaving an abusive relationship ends the abuse is one of the most persistent misconceptions in domestic violence discourse. A substantial body of research indicates that post separation abuse is not only common but that coercive control after separation frequently escalates in both intensity and complexity. Understanding why and how an ex partner may continue to exert ongoing control is essential for legal practitioners, family courts, social services, and policymakers who encounter these dynamics.
The Research Evidence on Continuation and Escalation
Multiple studies across several countries have documented the persistence of controlling behaviour after a relationship ends. Relatively little research had, until recently, examined men’s use of coercive controlling tactics against female partners after separation. A mixed-methods secondary analysis of 346 Canadian women, published by Tutty, Radtke, and Nixon (2024) in Violence Against Women, found that 86.4% of women identified at least one coercive controlling tactic used by their ex-partners. Those tactics included stalking and harassment, financial abuse, and efforts to discredit the women to various authorities.
Broughton and Ford-Gilboe (2017) noted in their quantitative secondary analysis of 157 Canadian mothers that, despite being separated for an average of 2.5 years, the majority continued to experience coercive control. Hayes (2012) found that although physical violence often decreases after physical separation, coercively controlling behaviours tend to persist or increase. The Australian Institute of Family Studies has stated that this is consistent with broader research finding that coercive control and violent behaviours continue and may escalate during and after separation.
These findings challenge the incident-based model of domestic violence, which treats abuse as a series of discrete assaults. The pattern-based model, as articulated by Evan Stark in his 2007 book Coercive Control: How Men Entrap Women in Personal Life, reframes abuse not as a set of individual violent acts but as a course of conduct more akin to hostage-taking, in which perpetrators deny women their personhood. Under this framework, the end of cohabitation does not necessarily end the conditions of entrapment.
How Separation Functions as a Trigger
Separation itself can act as a catalyst for escalation. Professor Jane Monckton Smith’s research on intimate partner homicide, which examined 372 cases of intimate partner homicide, identified a dominant eight-stage chronological sequence leading to lethal violence. The model is based on an understanding that coercive control is the most effective predictor for homicide. In this timeline, a trigger that threatens the perpetrator’s control, such as separation or threats of separation, marks a critical stage of escalation.
Lethality data underscore the danger of this period. The Femicide Census (2018) identified that 41% of women killed by a partner or former partner had separated or taken steps to separate, with 30% killed within the first month and 70% killed within the first year of separation. Leeds City Council, drawing on Domestic Homicide Reviews, has noted that coercive control is a significant indicator of risk to life, especially after a relationship has ended.
The Channels of Ongoing Control by an Ex Partner
Research identifies several distinct mechanisms through which ongoing control by an ex partner persists after the relationship concludes.
Legal systems and court proceedings. Abusive partners may use legal systems to continue controlling their ex-partners. Douglas’s (2018) interviews with 65 Australian women identified conflicts involving civil protection orders, court appearances, calling inappropriate witnesses, and contacting child protective services. Miller and Smolter (2011) labelled this subset of legal post-separation coercive tactics “paper abuse” or “procedural stalking.” Research published in the Journal of Family Violence in 2026 found that higher frequencies of coercive control were significantly associated with a higher rate of court filings by both perpetrators and survivors before the final divorce decree.
Child arrangements. Existing legal and welfare frameworks often lack the conceptual and diagnostic tools to identify coercive control tactics that persist after separation, such as the weaponization of child arrangements or exploitation of court processes. Katz (2020) documented how domestic violence perpetrators can use coercive control against their children after separation, with tactics including violence, threats, intimidation, stalking, monitoring, emotional abuse, and manipulation interwoven with periods of seemingly “caring” behaviour.
Economic abuse. Economic abuse often occurs in the context of intimate partner violence and involves the control of a partner or ex-partner’s money and finances, as well as the things that money can buy. Financial deprivation can continue long after physical separation through withholding of support payments, deliberate depletion of joint assets, and interference with employment.
Mischaracterisation of conflict. These behaviours are too often mischaracterised as “high conflict” rather than recognised as strategic efforts by perpetrators to continue patterns of abuse. Research has found that court mediators in some settings minimised emotional abuse and controlling behaviours, prioritising physical abuse as the primary indicator of harm, with the result that mothers’ reports of psychological abuse were dismissed or reframed as mutual conflict.
Legislative Responses to Post Separation Abuse
Several jurisdictions have moved to address the gap between relationship-based conceptions of domestic abuse and the reality of ongoing coercive control after separation. In England and Wales, controlling or coercive behaviour is a crime under section 76 of the Serious Crime Act 2015. The Domestic Abuse Act 2021 extended this offence so that controlling or coercive behaviour can now potentially be prosecuted as a criminal offence even if the parties are no longer in a relationship and are not living together. The section of the Act that criminalised controlling or coercive behaviour taking place after separation came into force on 5 April 2023.
The Duluth Post-Separation Power and Control Wheel has been proposed as a tool to help recognise coercive legal strategies that are frequently minimised as routine conflict. While helpful to grasp the primary pillars of post-separation abuse, the Duluth Post-Separation Power and Control Wheel lacks the depth required to understand the range of coercive control tactics in a forensic environment. Some scholars argue for a shift towards contextual, pattern-based risk assessments in private family law, backed by statutory training and legal reform. Others are hiring forensic coercive control experts to show the court how the abuse is hiding in plain sight.
As of 2024, laws criminalising coercive control have been passed throughout the United Kingdom, in the Republic of Ireland, the Australian state of New South Wales, the US states of Connecticut, Arizona, Colorado and Hawaii, and federally in Canada. The scope and approach of these laws vary significantly across jurisdictions, and whether they adequately capture post-separation dynamics remains a subject of ongoing legal arguments.
Why This Matters
The weight of evidence indicates that separation can represent one of the most dangerous periods for those who have experienced coercive control. Post-separation can see an escalation of abuse, with women reporting continued threats and intimidation when leaving an abusive partner as well as an increased risk of homicide. Studies have demonstrated that women who reported higher levels of coercive control during the relationship also reported higher levels of coercive control during separation, and women who reported coercive control during the relationship reported higher levels of harassment and fear after separation.
These findings carry implications for risk assessment, safety planning, and the design of family court processes. If legal and welfare systems continue to treat physical separation as the resolution of domestic abuse, they may inadvertently create conditions in which coercive control after separation goes unrecognised, and in which the ongoing control exercised by an ex partner proceeds without effective intervention. If an ex partner’s messages concern you, run a free coercive control check on a message.
