Custody battles can be emotionally draining, legally complex, and life-altering for both parents and children. At Mattis Law, A.P.C., we’ve seen how avoidable errors can negatively impact even the most well-meaning parents.

That’s why we’ve compiled a comprehensive guide to the top child custody mistakes San Diego parents should avoid. Whether you’re just beginning the process or are in the middle of a contested dispute, avoiding these common missteps is critical to protecting your parental rights and building a stable future for your child.

Speaking Poorly About the Other Parent

One of the most damaging mistakes parents make during a custody case is badmouthing the other parent in front of their child or in court. Judges in San Diego family court are highly focused on the best interests of the child, and fostering a positive co-parenting relationship is considered a key part of that.

What not to say in court: Avoid any emotionally charged statements that accuse, blame, or insult the other parent without evidence. Stick to facts. Avoid speaking negatively to your child about their other parent, even in private.

Custody battle tip: Judges view parents who support their child’s relationship with the other parent more favorably. Demonstrating maturity, restraint, and cooperation works in your favor.

Withholding Visitation or Custody

Unless there is a verified safety concern, denying the other parent access to your child without a court order can severely harm your case. Even if tensions are high, parents must follow existing custody or visitation orders or risk being held in contempt of court.

Judges often interpret unilateral decisions as unwillingness to co-parent, which can work against the offending party in future rulings.

Legal strategy for custody cases: If you believe visitation should be modified, work through your attorney to file a motion, not through self-enforcement.

Ignoring Temporary Court Orders

Temporary custody orders carry the same legal weight as permanent ones. Ignoring them shows a disregard for court authority, which can damage your credibility.

If a judge has issued temporary instructions on custody, visitation, or communication, follow them closely even if you disagree. Failing to do so may result in sanctions or a change in legal custody.

Family court dos and don’ts: Do respect every court order. Don’t assume anything is optional.

Using Your Child as a Messenger or Spy

Trying to communicate with your co-parent through your child or fishing for information puts unnecessary pressure on your child and risks the court viewing you as manipulative. Children should never be asked to take sides.

This tactic can quickly backfire in court, and judges often frown on behavior that disrupts a child’s emotional well-being.

Custody battle tip: Keep adult issues between adults. Use court-approved parenting apps or your attorney to communicate if needed.

Oversharing or Venting on Social Media

In today’s digital world, social media posts are regularly used as evidence in family court. Sharing complaints about the custody process, your ex, or even your child can reflect poorly on your character. Avoid posting anything that you wouldn’t want a judge to read aloud. That includes photos, comments, and private messages.

What seems like harmless venting can be interpreted as a lack of discretion or hostility. Even private posts can be subpoenaed.

Failing to Prepare for Court

Walking into a custody hearing unprepared is one of the most serious mistakes a parent can make. Whether you are representing yourself or working with an attorney, preparation is key. The more organized and informed you are, the more seriously the judge will take your position.

Bring relevant documents, records, and a clear understanding of what you’re asking for and why. Know your parenting schedule, school history, and any special needs or concerns about your child.

Letting Emotions Control Your Decisions

Custody battles are often fueled by intense emotions, but making decisions based on anger, hurt, or revenge rarely benefits your child and can backfire legally.

Don’t refuse mediation just to “teach the other parent a lesson.” Don’t escalate minor issues into major legal battles without justification. Judges can tell when parents are acting out of spite rather than concern.

Family court dos and don’ts: Do focus on the child’s needs. Don’t let your emotions sabotage your long-term goals.

Not Documenting Incidents or Concerns

If your co-parent has engaged in concerning behavior, such as missing pickups, refusing to communicate, or exposing the child to unsafe conditions, document everything. Your word alone is not enough. Credible documentation often plays a pivotal role in court outcomes.

Keep a log of dates, times, and details. Save emails, texts, and photos where appropriate. Your attorney can help you determine which evidence is admissible.

Representing Yourself Without Legal Guidance

While self-representation may seem cost-effective, it can put you at a major disadvantage, especially if your co-parent has an attorney. Family law is complex, and custody outcomes often hinge on how well your case is presented. Never underestimate the value of experienced legal representation, particularly when your child’s future is on the line.

Working with a knowledgeable San Diego family law attorney ensures your rights are protected, your documentation is properly submitted, and your strategy is sound.
