Concepts and methods in family matters
Evidence-based methods and questions of evidence in custody disputes
What's at stake: In custody disputes where violence occurs or is alleged, the quality of the material the court bases its decision on determines how legally secure and safe the outcome is for the child and the parent at risk. The call for evidence-based methods aims to reduce the risk that unsubstantiated theories or unfounded claims carry too much weight in such rulings.
Case texts and AI reasoning are AI-translated from the Swedish originals; the Swedish text is authoritative.
What the vote decides
The question is whether the government should be directed to take general measures to ensure evidence-based methods are used in custody disputes, particularly where there are allegations of violence, or whether the current principles of free presentation of evidence and the courts' own assessment of evidence should remain unchanged.
Yes Yes — the committee proposal
The committee rejects all the motions. The committee stands by its previous positions and stresses that under Swedish law it is the parties themselves who present their arguments and invoke evidence, after which the court freely assesses that evidence; restricting which evidence may be invoked would undermine the principles of free presentation and free assessment of evidence. The committee also sees no reason to investigate theories of parental alienation or to proceed with special competence requirements for judges beyond the training already provided within the Swedish courts system.
No No — the reservations
Reservation 23 (V, C, MP)
The reservation (V, C, MP) calls for the government to take general measures to ensure that evidence-based methods are used in custody disputes and form the basis for court rulings, particularly where there are allegations of violence. The reasoning is that current legislation and agencies' guiding documents are unclear, and that evidence and science must underpin such disputes for abused women and children to be guaranteed a legally secure and fair hearing.
Summarised from the committee report. Party labels in the summary come from the report, not from the vote.
What do the votes mean here?
Yes The committee proposal: rejecting the motions (keeping things as they are).
No Backing the counter-proposal: reservation 23 by V, C, MP.
Abstain The party marks a position of its own that is not one of the two final alternatives.
What each plan points to — and how the party voted
For each party: the vote its own election manifesto and party programme point to in this case, next to how the party actually voted. A plan can only point to Yes or No; a party can also abstain.

Riksdag decision: The Riksdag rejected approximately 140 proposals on family law in motions from the general motion period 2025. The proposals concern, among other things, reflection time for divorce, property division, legal assistance for children, questions about custody, residence and visitation in case of domestic violence, the system of guardians, administrators, and certain questions about name changes. The Riksdag refers, among other things, to ongoing work and the committee's previous positions.
Counter-proposals
- The counter-proposal wants to make family law provisions on parenthood simpler, clearer, and gender-neutral to apply uniformly to all family types. (V, C, MP) — Reservation 23
Plan vs actual vote
Every party, in chamber order: what its own plan pointed to, how it voted, and the reasoning behind both. Highlighted rows are where the two differ — but a vote that follows the plan is a result too, so the reasoning is there for every party.
The election manifesto demands that the child's perspective be strengthened in custody disputes and that knowledge in the judicial system about violence against women and children increases, which is precisely what the requirement for evidence-based methods in custody cases aims for.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The election manifesto demands that the child's perspective be strengthened in custody disputes and that knowledge in the judicial system about violence against women and children increases, which is precisely what the requirement for evidence-based methods in custody cases aims for. The party programme wants work against violent crime to be based on research. That judicial processes are built on science is therefore a commitment the plan has already made.
Original (Swedish)
Valplattformen kräver att barnperspektivet stärks i vårdnadstvister och att kunskapen i rättsväsendet om våld mot kvinnor och barn ökar, vilket är precis vad kravet på evidensbaserade metoder i vårdnadsmål syftar till. Partiprogrammet vill att arbetet mot våldsbrottslighet utgår från forskningen. Att rättsprocesser bygger på vetenskap är därmed ett åtagande planen redan gjort.
- knowledge in the judiciarydecisive»ökad kunskap inom rättsväsendet om samtycke och om våld mot kvinnor och barn« (2022 manifesto ↗)“increased knowledge within the judicial system about consent and about violence against women and children”
- research-based work against violence»Vi vill se ett genomgripande arbete mot våldsbrottslighet, som utgår« (party programme ↗)“We want to see comprehensive work against violent crime, which is based”
- child's perspective in custody disputes»Barnperspektivet måste stärkas i vårdnadstvister och det ska inte vara möjligt för våldsutövare att behålla gemensam vårdnad.« (2022 manifesto ↗)“The child's perspective must be strengthened in custody disputes and it should not be possible for perpetrators of violence to retain joint custody.”
The plan requires that policy in criminal law be built on evidence, efficiency and rule of law, and that violence against children and men's violence against women are combated forcefully with support to the affected.
Plan documents: party programme · 2022 manifesto
Reasoning and quotes
The plan requires that policy in criminal law be built on evidence, efficiency and rule of law, and that violence against children and men's violence against women are combated forcefully with support to the affected. That evidence-based methods shall underpin assessments in custody disputes where violence occurs follows directly from these commitments. The plan does not address family law procedures, however.
Original (Swedish)
Planen kräver att politiken på rättsområdet byggs på evidens, effektivitet och rättssäkerhet, och att våld mot barn och mäns våld mot kvinnor bekämpas kraftfullt med stöd till utsatta. Att evidensbaserade metoder ska bära bedömningarna i vårdnadstvister där våld förekommer följer direkt av dessa åtaganden. Planen tar dock inte upp familjemålens processregler.
- evidence and rule of lawdecisive»Kriminalpolitik byggd på evidens, effektivitet och rättssäkerhet.« (party programme ↗)“Criminal policy built on evidence, efficiency and rule of law.”
- protection of children against violence»Kraftfullt bekämpande av våld mot barn och stöd till barn som bevittnar våld.« (party programme ↗)“Forceful combating of violence against children and support to children who witness violence.”
- violence as exercise of power»Mäns våld mot kvinnor är en maktutövning som står i direkt motsats mot dessa principer.« (party programme ↗)“Men's violence against women is an exercise of power that stands in direct contradiction to these principles.”
- measures against men's violence»• Krafttag för att stoppa hedersrelaterat våld, sexualbrott och mäns våld mot kvinnor. Vi vill fort sätta den politiska riktning som skärpt straffen för våld och andra kränkningar i nära relationer, och som ökat resurserna till kvinno- och tjejjourernas viktiga arbete.« (2022 manifesto ↗)“• Measures to stop honour-based violence, sexual offences and men's violence against women. We want to continue the political direction that has tightened penalties for violence and other abuse in close relationships, and that has increased resources to women's and girls' important shelter work.”

The plan wants to protect children from being forced to have contact with a violent parent and establishes that the best interests of the child must always be decisive.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The plan wants to protect children from being forced to have contact with a violent parent and establishes that the best interests of the child must always be decisive. It is also built on a scientific approach and requires that legal certainty is guaranteed throughout the legal system. That evidence-based methods should underpin court rulings in custody cases with allegations of violence follows from these commitments.
Original (Swedish)
Planen vill skydda barn från att tvingas till umgänge med en våldsam förälder och slår fast att barnets bästa alltid ska vara avgörande. Den bygger dessutom på ett vetenskapligt förhållningssätt och kräver att rättssäkerheten garanteras i hela rättssystemet. Att evidensbaserade metoder ska ligga till grund för domsluten i vårdnadsmål med uppgifter om våld följer av dessa åtaganden.
- protection from violent parentdecisive»skydda barn från att tvingas till umgänge med en våldsam förälder.« (2022 manifesto ↗)“protect children from being forced to have contact with a violent parent.”
- best interests of the child decisive»Barnkonventionen är svensk lag och barnets bästa ska alltid vara avgörande när beslut fattas kring barn.« (party programme ↗)“The Convention on the Rights of the Child is Swedish law and the best interests of the child must always be decisive when decisions are made concerning children.”
- legal certainty throughout the system»Alla ska vara lika inför lagen och rättssäkerheten måste garanteras i hela rättssystemet.« (party programme ↗)“Everyone shall be equal before the law and legal certainty must be guaranteed in the entire legal system.”
- scientific basis for decisions»Vetenskap och bildning bidrar till förståelse för vår omvärld och kunskap att utveckla ett hållbart samhälle.« (party programme ↗)“Science and education contribute to understanding our world and knowledge to develop a sustainable society.”
The plan commits the party to leading Sweden towards an end to men's violence against women and strengthening the victim perspective, and that children's rights shall carry greatest weight when society acts.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The plan commits the party to leading Sweden towards an end to men's violence against women and strengthening the victim perspective, and that children's rights shall carry greatest weight when society acts. That custody disputes where violence occurs are resolved with evidence-based methods is a prerequisite for violence-affected women and children to get fair trial. The plan says nothing about burden of proof in family cases.
Original (Swedish)
Planen förbinder partiet att leda Sverige mot ett slut på mäns våld mot kvinnor och att stärka brottsofferperspektivet, och att barnens rättigheter ska väga tyngst när samhället agerar. Att vårdnadstvister där våld förekommer avgörs med evidensbaserade metoder är en förutsättning för att våldsutsatta kvinnor och barn ska få en rättssäker prövning. Planen säger dock inget om bevisrätten i familjemål.
- stop men's violence against womendecisive»Vi ska leda Sverige mot ett slut på mäns våld mot kvinnor. Män som slår ska inte komma undan.« (2022 manifesto ↗)“We shall lead Sweden towards an end to men's violence against women. Men who hit must not escape.”
- strengthened victim perspective»Brottsofferperspektivet måste stärkas. Den som utsatts för brott ska få upprättelse och bättre stöd.« (2022 manifesto ↗)“The victim perspective must be strengthened. Those affected by crime shall get redress and better support.”
- children's rights»Av största betydelse är då barnens rättigheter och perspektiv.« (party programme ↗)“Of greatest importance is then the rights and perspective of children.”
- fair trial»Alla som bor i Sverige ska kunna få sin sak prövad.« (2022 manifesto ↗)“Everyone who lives in Sweden shall be able to have their case heard.”
The plan requires that support measures be scientifically based and that legal security and protection of civil and political rights be strengthened.
Plan documents: party programme
Reasoning and quotes
The plan requires that support measures be scientifically based and that legal security and protection of civil and political rights be strengthened. It also affirms that all violence in close relationships shall be combated and that children shall not be forced into visitation with a violent parent. The demand for evidence-based methods in custody disputes, especially when there are allegations of violence, follows from these commitments. The plan, however, says nothing about what evidence may be invoked.
Original (Swedish)
Planen kräver att stödinsatser ska vara vetenskapligt grundade och att rättssäkerheten och skyddet för fri- och rättigheter förstärks. Den slår också fast att allt våld i nära relationer ska bekämpas och att barn inte ska tvingas till umgänge med en våldsam förälder. Kravet på evidensbaserade metoder i vårdnadstvister, särskilt när det förekommer uppgifter om våld, följer av dessa åtaganden. Planen säger däremot inget om vilken bevisning som får åberopas.

The party programme requires that handling of cases concerning violence in close relationships be based on well-trained staff and functioning cooperation, and makes the best interests of the child governing in all decisions concerning children.
Plan documents: party programme
Reasoning and quotes
The party programme requires that handling of cases concerning violence in close relationships be based on well-trained staff and functioning cooperation, and makes the best interests of the child governing in all decisions concerning children. Requirements that evidence-based methods be used in custody disputes is a quality issue of that kind and is therefore supported in substance. The plan simultaneously values free and independent courts, which makes the support cautious.
Original (Swedish)
Partiprogrammet kräver att handläggning av ärenden som rör våld i nära relationer vilar på välutbildade medarbetare och fungerande samverkan, och gör barnets bästa styrande vid alla beslut som rör barn. Krav på att evidensbaserade metoder används i vårdnadstvister är en kvalitetsfråga av det slaget och stöds därför i sak. Planen värnar samtidigt fria och oberoende domstolar, vilket gör stödet försiktigt.
- expertise in violence in close relationshipsdecisive»Effektiv handläggning av ärenden som rör våld i nära relationer förutsätter välutbildade medarbetare hos polis, åklagare, socialtjänst och hälso- och sjukvård samt ett väl fungerande samarbete mellan myndigheterna.« (party programme ↗)“Effective handling of cases concerning violence in close relationships requires well-trained staff at the police, prosecution, social services and health and medical care and good cooperation between the authorities.”
- best interests of the child governing»Barnets bästa ska vara styrande i all familjepolitik och vid alla beslut som rör barn.« (party programme ↗)“The best interests of the child shall be governing in all family policy and in all decisions concerning children.”
- protection for victims of violence»Kvinnor, män och barn som utsatts för våld i en nära relation ska ges adekvat stöd och skydd.« (party programme ↗)“Women, men and children who have suffered violence in a close relationship shall be given adequate support and protection.”
- independent and legally secure courts»Domstolarna ska stå fria och oberoende från statsmakterna och handlägga mål och ärenden på ett rättssäkert och effektivt sätt.« (party programme ↗)“Courts shall be free and independent from the state authorities and handle cases and matters in a legally secure and effective manner.”
The plan takes no explicit position on what the committee actually decided — often because the committee's reason was procedural. The stance is derived and fully cited, but it does not show the party broke a commitment.
The plan wants to strengthen the independence of the courts and a legal system that judges justly, which speaks against politically prescribing which methods should underpin judicial decisions in custody cases.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The plan wants to strengthen the independence of the courts and a legal system that judges justly, which speaks against politically prescribing which methods should underpin judicial decisions in custody cases. The party programme's requirement for research and proven experience supports the ambition in substance. The plan's response to violence in close relationships is specialized investigation teams rather than directing courts' assessment of evidence.
Original (Swedish)
Planen vill stärka domstolarnas oberoende och ett rättsväsende som dömer rättssäkert, vilket talar mot att politiskt föreskriva vilka metoder som ska ligga till grund för domsluten i vårdnadsmål. Partiprogrammets krav på forskning och beprövad erfarenhet stöder däremot ambitionen i sak. Planens svar på våld i nära relationer är specialiserade utredningsgrupper snarare än styrning av domstolarnas bevisvärdering.

The plan requires that investigations concerning children be quality-assured and legally secure and that knowledge is raised among all those working with family law matters.
Plan documents: 2022 manifesto
Reasoning and quotes
The plan requires that investigations concerning children be quality-assured and legally secure and that knowledge is raised among all those working with family law matters. The counter-proposal's requirement for general measures that ensure that evidence-based methods are the basis for judgements in custody disputes follows from this, in line with the plan's stated confidence in science over untested theories. However, the plan does not address evidence presentation in family cases.
Original (Swedish)
Planen kräver att utredningar som rör barn ska vara kvalitetssäkrade och rättssäkra och att kunskapen höjs hos alla som arbetar med familjerättsliga frågor. Motförslagets krav på generella åtgärder som säkerställer att evidensbaserade metoder ligger till grund för domsluten i vårdnadstvister följer av det, i linje med planens uttalade tilltro till vetenskap framför oprövade teorier. Planen tar dock inte upp bevisföring i familjemål.
- rättssäkra barnutredningardecisive»Utredningar rörande barn ska vara kvalitetssäkrade och rättssäkra.« (2022 manifesto ↗)“Investigations concerning children must be quality-assured and legally secure.”

- kvalitet i barnärenden»Öka kvalité och rättssäkerhet i utredningar om barn« (2022 manifesto ↗)“Increase quality and legal security in investigations on children”
- vetenskap framför teorier»Vi tror på vetenskap och inser att förvirrande genusteorier får förödande konsekvenser när de omsätts i praktiken.« (2022 manifesto ↗)“We believe in science and recognize that confusing gender theories have devastating consequences when implemented in practice.”
