Going through a divorce is difficult enough without the added stress of a custody battle. Parents naturally want what is best for their children, but emotions can run high during this challenging time. Unfortunately, certain behaviors and oversights can negatively impact your custody case without you even realizing it. Understanding these common pitfalls can help you avoid costly errors and demonstrate to the court that you are the responsible, stable parent your children need.

Speaking Negatively About Your Co-Parent
Perhaps the most damaging mistake a parent can make during a custody dispute is speaking negatively about the other parent, especially in front of the children. This behavior is problematic for several important reasons that extend far beyond simple politeness.
When you criticize your co-parent, you are also criticizing your child. Your child is made up of half of that other person, which means you are essentially insulting half of their DNA, half of their personality, and half of everything about them. Children are perceptive and internalize these negative comments, which can cause lasting emotional harm and damage their sense of self-worth.
From a legal perspective, this behavior can be equally damaging to your case. New York courts expect both parents to promote a healthy relationship between the child and the other parent. When negative comments come to light during custody proceedings, it demonstrates that you are violating this fundamental duty. The court will view this as evidence that you have no desire to maintain a cohesive co-parenting relationship, which is not the impression you want to make when seeking custody or increased parenting time.
The bottom line is simple: no matter how frustrated or hurt you may feel about your co-parent, keep those feelings away from your children and out of any communications that could be presented in court.
Failing to Document Important Events and Interactions
Memory is unreliable, especially during stressful periods like a divorce. Events that seem unforgettable in the moment can become fuzzy over time, and important details can be lost entirely. This is why documentation is essential in any custody case.
When something goes wrong, whether it is a violation of your custody agreement, poor behavior by your co-parent, or a dangerous situation involving your children, you need to document it immediately. Creating a record at the time the event occurs, known as contemporaneous documentation, carries significant weight in court because it is considered more reliable than memories recalled months or even years later.
One effective method is keeping a dedicated journal where you record events as they happen. Write down dates, times, what occurred, who was present, and any other relevant details. If you maintain this journal consistently and update it at the time events occur, it can be admitted as evidence in court proceedings.
An even more effective approach is using a co-parenting app such as Our Family Wizard. These applications offer multiple advantages for parents navigating custody arrangements. They provide a shared calendar so both parents can see scheduled parenting time and events. They include text messaging and email features that are automatically saved and timestamped. Most importantly, all communications are stored in one place and can be easily reproduced as evidence if needed.
The key is consistency. Whether you choose a handwritten journal, a co-parenting app, or both, make documentation a regular habit rather than something you do only when major problems arise.
Missing Scheduled Parenting Time
Life happens, and occasionally missing a scheduled visit or being a few minutes late for pickup is understandable. An isolated incident of missing a weekend or a single day is unlikely to have any long-term effect on your parenting agreement. Courts recognize that parents are human and that unexpected situations arise.
However, patterns of unreliability are treated very differently. If you are constantly missing your scheduled parenting time, repeatedly canceling at the last minute, or regularly showing up hours late for drop-offs and pickups, the court will take notice. This type of behavior demonstrates a lack of commitment to your children and disrespect for both the custody agreement and your co-parent.
Consistent unreliability can become grounds for modifying your parenting time arrangement. If your co-parent can document a pattern of missed visits or chronic lateness, they may petition the court to reduce your custody time. The court’s primary concern is always the best interests of the child, and a parent who cannot be counted on to show up is not serving those interests.
If you know in advance that you cannot make a scheduled visit, communicate this to your co-parent as soon as possible. Being proactive about schedule changes shows responsibility and respect, which are qualities courts look for in determining custody arrangements.
Poor Communication With Your Co-Parent
Effective communication with your co-parent is not just about being polite; it is about demonstrating to the court that you are capable of putting your children’s needs first. Courts pay close attention to how parents communicate with each other because it reveals a great deal about who will be the more stable custodial parent.
Good communication means keeping your co-parent informed about matters that affect your children. If you are going to be late for pickup or drop-off, let them know. If you learn about a school event that you think your co-parent might not be aware of, share that information. If something comes up three weeks in advance that will affect the parenting schedule, communicate about it as soon as you know rather than waiting until the last minute.
This type of consistent, respectful communication demonstrates several things to the court. It shows that you prioritize your children’s wellbeing over any personal conflicts with your co-parent. It demonstrates that you are organized and responsible. Most importantly, it shows that you are capable of maintaining a functional co-parenting relationship, which is essential for your children’s long-term stability and happiness.
On the other hand, poor communication, such as failing to inform your co-parent about schedule changes, withholding information about school events or medical appointments, or refusing to respond to reasonable inquiries, paints a very different picture. Courts may interpret this behavior as an attempt to marginalize the other parent or as evidence that you are not capable of the cooperation required for effective co-parenting.
Protecting Your Rights During a Custody Dispute
Understanding what not to do during a custody case is just as important as knowing what you should do. By avoiding these common mistakes, you put yourself in a stronger position to achieve a custody arrangement that serves your children’s best interests while protecting your parental rights.
Every custody case is unique, and the specific facts of your situation will determine the best approach for moving forward.
