Most parents are unfamiliar with custody court and – understandably – often underestimate its complexities. The overarching, single biggest mistake is that they fail to understand – and align their case with – how the court considers their child’s best interests. As a result, they make additional mistakes that can seriously harm their case.
Really, the most common errors I’ve witnessed parents make all boil down to:
- Inadequate preparation
- Limited knowledge of the legal process
- Dishonesty
- Failure to take responsibility
Each of these mistakes can shift the outcome of a custody case, often in ways parents never anticipated.
Mistake #1: Not understanding the legal standards or how judges make decisions
A parent must understand the proper legal standard and how decisions are made. Courts don’t rely on instinct or “common sense.” They use legal standards that vary depending on the type of request. For example, the standard for changing a parenting schedule is often different from the standard for deciding custody.
Each standard comes with specific factors the judge must consider, and parents should build their case around those factors.
Another common misstep? Bringing up issues that are not legally relevant. For instance, a parent may focus on their ex’s new partner or irregular work schedule – as a way to reduce visitation, or otherwise show them in an unfavorable light – while the judge is far more concerned about the child’s medical needs, educational stability, and overall well-being.
Mistake #2: Not presenting your case the right way
Once a parent understands the legal standards judges use, they can present their evidence in a way that actually helps the judge. But too often, parents focus on the wrong details.
For instance, a mother or father may go on and on about how they are better suited to helping their child engage in extracurricular activities… but say nothing about doctor visits, school performance, or even the distance between the parents’ homes — all things the court actually weighs when deciding what’s in the child’s best interest.
Another common problem is assuming something is “obvious” and not backing it up with evidence.
Take this example: A mother asks to move the children to her school district. The children have been in the father’s district for ten years, and he assumes the judge will see no reason to switch schools. Because he doesn’t testify about the quality of the current district or the children’s stability there, the only evidence the judge hears is from the mother about why her district is better.
Even if the father’s position makes sense, the court can’t rely on assumptions – it has to compare the actual evidence presented.
Mistake #3: Not recognizing that honesty strengthens your case
Nothing undermines your credibility faster than a lie – even if the truth isn’t entirely in your favor.”
Custody battles are stressful, and it’s natural for parents to feel backed into a corner. In those moments, some may be tempted to stretch the truth – whether it’s about their work schedule, who they live with, what time they picked up the children, or conversations with the child’s doctors. But even small fibs can backfire.
The best approach is always honesty. Judges can overlook minor flaws, but nothing undermines your credibility faster than a lie – even if the truth isn’t entirely in your favor.
During custody proceedings, the other parent will present evidence – things like medical records, communications with teachers or doctors, and text messages. If you are not truthful, those lies usually come out in court.
When that happens, the judge’s attention shifts away from what really matters – your child’s well-being – and focuses on your credibility instead. Lying is never worth it, yet it remains a common mistake parents make.
Mistake #4: Not taking accountability for past or present mistakes
Along with being honest, it’s important for parents to take accountability.
For example, if a parent previously traveled frequently for work and wasn’t always available for their child, that’s understandable – the court can see that circumstances change over time. The key is not to pretend it didn’t happen. Acknowledging the past and showing how you’ve adjusted demonstrates responsibility and builds credibility with the judge.
This is especially important if a parent has a current or past issue with drugs, alcohol, or mental health. Unfortunately, case studies show that parents don’t seek help because they worry they will lose their children… but, ironically, not seeking help can lead them to lose custody.
If you’re in counseling, share that and provide your attendance history. If you’re overcoming alcohol addiction, explain that you attend support meetings like Alcoholics Anonymous or use alcohol monitoring tools (like BACtrack View) before parenting time. Denying a problem, on the other hand, can quickly diminish the judge’s trust. By addressing these issues honestly and showing the steps you’re taking to manage them, you demonstrate responsibility, gain credibility, and earn the court’s respect.
Judges understand that everyone faces challenges, and they generally won’t hold it against you — as long as you are honest and upfront.
Mistake #5: Ignoring court orders
As mentioned earlier, the court considers a variety of factors when deciding parenting issues. One of the most important is whether a parent can follow court orders.
Violating an order is a major mistake. It signals to the court that you can’t be trusted, don’t take the process seriously, and don’t respect authority. It can even suggest that you might put your child at risk. The other parent will often point to any violations as evidence against you.
On the other hand, if you consistently follow court orders, stay honest, and focus on your child’s best interests, you greatly improve your chances of success in custody proceedings.
The bottom line on custody battle mistakes
Custody cases aren’t about being the “better” parent – they’re about showing the court that you understand what your child needs and that you can meet those needs consistently and responsibly. The biggest missteps parents make usually come from a lack of preparation, misunderstanding how the system works, or trying to present themselves as perfect instead of genuine.
Judges don’t expect perfection, but they do expect honesty, accountability, and clear evidence tied to the legal standards they must follow. If you understand those standards, stay truthful, own your past, and focus your case on your child’s best interests – not on attacking the other parent – you’ll be miles ahead of most.
In custody court, credibility is everything. Build it, protect it, and let it speak for you.
