I want to talk about something that took me two years and $250,000 to finally understand: the science has been on our side the whole time.
There is a massive body of research on shared parenting and what it actually does for kids, and honestly, when you start reading it, you get this weird mix of feelings, you know? Like relief because the data backs up what every good dad already knows intuitively, and also this deep frustration because if the courts actually followed the research, so many fathers would not have had to fight as hard as we did.
So let me walk you through what the studies actually say, not the watered-down version, but the real numbers, and then we can talk about why any of this matters for you if you are in the middle of a custody fight right now.
The Core Finding: Equal Time Is Not Just Good for Dads
The most important thing the research shows is that shared parenting benefits children across basically every measurable outcome. We are talking about academic performance, emotional health, behavioral outcomes, mental health in adulthood, physical health, and even their own relationships later in life.
A landmark 2017 meta-analysis by Dr. Linda Nielsen, published in the Journal of Divorce and Remarriage, reviewed over 60 studies comparing children in shared parenting arrangements to children in sole custody. The findings were pretty clear: children in shared parenting scored better on virtually every measure of wellbeing.
Dr. Nielsen has spent decades studying this and her conclusion is not subtle. Shared parenting is better for children in the vast majority of cases, including situations where parents have conflict, which is the exact objection courts love to use to deny fathers equal time.
A 2014 study by Bauserman, analyzing 33 separate studies, found that children in joint custody arrangements had better outcomes than children in sole custody on measures of general adjustment, family relationships, self-esteem, and behavioral and emotional adjustment. And this was true even when controlling for conflict between parents.
What Happens When Fathers Are Pushed Out
The flip side of the research on shared parenting is the research on what happens when fathers are minimized or removed. And this is where it gets hard to read, because these are real kids we are talking about.
Children who grow up with limited or no father involvement are statistically more likely to experience:
- Depression and anxiety disorders
- Academic failure and dropout
- Substance abuse
- Involvement in the criminal justice system
- Teen pregnancy
- Long-term economic instability
The U.S. Census Bureau consistently reports that children in father-absent homes are four times more likely to live in poverty. The National Fatherhood Initiative has documented that 63% of youth suicides come from fatherless homes, 90% of homeless and runaway children are from fatherless homes, and 85% of children who exhibit behavioral disorders come from fatherless homes.
I am not sharing these numbers to be dramatic. I am sharing them because they represent the real stakes of what courts are deciding when they default to primary custody with one parent and every-other-weekend with the other.
The “High Conflict” Myth
If you have been through family court, you have probably heard this one. The judge or the evaluator or opposing counsel says something like, well, there is too much conflict between the parents for shared parenting to work.
Here is what the research actually says about that.
A 2014 study by Dr. Robert Bauserman found that joint custody was associated with better outcomes for children even in high-conflict situations. Not just in low-conflict families. Even when parents were fighting.
Dr. Nielsen’s research specifically addresses this objection. She found that children benefit from having both parents involved in their lives regardless of the level of inter-parental conflict, and that courts relying on conflict as a reason to deny shared parenting are not applying the research correctly.
Now look, I am not saying zero exceptions exist. There are cases involving domestic violence or abuse where shared parenting is genuinely dangerous. The research accounts for that. But the generic claim that “there is conflict between these parents so we cannot do shared parenting” is not scientifically supported. Conflict between parents happens in basically every divorce. That cannot be the bar.
What the American Psychological Association Says
In 2014, the American Psychological Association released a resolution on shared parenting that acknowledged the growing evidence that children benefit from having both parents actively involved in their lives. Multiple professional organizations have moved toward supporting shared parenting as the default presumption when both parents are fit and willing.
The Association for Family and Conciliation Courts and the American Law Institute have both produced materials supporting rebuttable presumptions of shared parenting in family law. “Rebuttable presumption” means shared parenting should be the starting point, and the burden should be on whoever wants to take that away, not on the father to prove he deserves equal time with his own kid.
That last part is important. Right now in most states, the system is backwards. A father has to prove why he should have equal time instead of the court starting from the assumption that equal time is best for the child. The research says we should flip that.
The International Evidence
The United States is behind on this. Other countries have actually moved toward shared parenting presumptions in law, and the results have been documented.
Belgium implemented a legal presumption of equal shared parenting in 2006. Research following that change found positive outcomes for children, including higher contact with both parents and reduced litigation costs because parents had less incentive to fight over custody when the presumption was already equal.
Australia moved toward shared parenting reforms in 2006, and subsequent research showed improvements in father involvement and child wellbeing, though debates about implementation have continued. The point is that other countries are running this experiment and the data is coming in.
Sweden, Denmark, the Netherlands, and several other European countries have been living with high rates of shared parenting for decades, and the research from those countries consistently shows that children do well under shared arrangements.
The Stability Argument Is Wrong Too
Another thing you will hear in court: children need stability, and moving between two homes disrupts that stability.
The research on this is pretty definitive. Dr. Nielsen reviewed studies specifically examining whether shared custody caused problems for children through instability or logistical stress, and found that the evidence does not support this concern. Children are resilient about moving between homes when both homes are safe and loving. What harms children is losing meaningful relationships with a parent.
A 2014 Swedish study by Malin Bergstrom and colleagues, looking at over 100,000 children, found that children in shared parenting had better health outcomes than children in sole custody, despite the so-called instability of moving between homes.
How to Use This Research in Your Case
If you are currently in a custody battle, this research matters for your case. Here is how to use it:
1. Ask your attorney about a shared parenting presumption. Some states have moved toward this, or have laws that require courts to consider it. Know what your state’s current standard is and whether it reflects the research.
2. Cite specific studies in your filings. Linda Nielsen’s work is particularly useful because she has specifically addressed the most common judicial objections. If the court is saying conflict is a barrier to shared parenting, Nielsen’s research directly counters that.
3. Request a custody evaluator who follows evidence-based practices. Not all custody evaluators are equally familiar with the research on shared parenting. You can ask about their professional training and whether they incorporate the current scientific literature in their assessments.
4. Document your involvement. The research on shared parenting outcomes assumes both parents are actively involved in caregiving. The more evidence you have of your actual involvement in your child’s life, the more a shared arrangement makes sense on its face. Check out our guide to documenting parental involvement for specifics on how to build that record.
5. Know that conflict does not disqualify you. If opposing counsel is trying to use any conflict between you and your co-parent as a reason to deny shared parenting, push back. The research does not support that argument except in cases of actual domestic violence or abuse.
Why This Matters Beyond Your Case
I fought for two years and spent more money than I want to think about to get 50/50 with my son Tanner. And honestly, that is considered a best-case outcome in the current system. I won. But I should not have had to fight that hard. The science was on my side the whole time.
The gap between what the research says and what courts actually do is real and it is harming kids every day. When courts default to sole custody with limited visitation, they are making a choice that the research says is worse for children. Not because judges are evil, I do not believe that. But because family law moves slowly and there are a lot of institutional forces that resist change, and meanwhile, fathers are paying the price and so are their kids.
The more fathers who know this research, the more we can push for systems that actually reflect what we know about child development. That is part of why I started this site. Not just to help individual dads survive their custody battles, but to be part of changing the conversation so the next generation of fathers does not have to fight as hard.
You deserve equal time with your child. The research agrees with you. Now we just need the courts to catch up.
