When deciding California custody cases, judges aren’t looking for a perfect parent. They’re looking for patterns of behavior that might affect a child’s safety, stability, and relationship with each parent. That’s why repeated conduct that seems unsafe, dishonest, hostile, or disruptive can do real damage in court.
Hopper Hopper & Strebe LLP represents parents in contested custody matters where these issues can quickly shape the outcome. Working with experienced Sacramento child custody attorneys can help parents avoid the mistakes that courts penalize the most.
What California Courts Consider in Custody Battles
California family courts focus intently on the best interests of the child when deciding custody. This governing standard comes from Family Code Section 3011, which directs judges to consider the health, safety, and welfare of the child, any history of abuse, and the nature and amount of contact each parent has with the child.
Is the Child Safe?
Safety concerns receive the most attention. Allegations involving neglect, substance abuse, unsafe living conditions, or exposure to dangerous people can change the direction of a case quickly.
In particular, the courts look for evidence of domestic violence, as a history of abuse is one of the most serious factors in custody cases.
Does the Parent Look Credible?
Judges also consider whether each parent appears truthful, consistent, and steady under pressure. False claims, changing stories, deleted messages, and social media posts that contradict the details of court filings can damage a custody-seeking parent’s credibility.
Will the Parent Support the Child’s Relationship with the Other Parent?
California’s custody laws place weight on whether one parent is willing to allow frequent and continuing contact with the other when that contact is in the child’s best interests. Tactics like preventing visits, bad-mouthing the other parent, or turning the child into a messenger can easily backfire.
10 Custody Mistakes That Can Damage Your Position

At Hopper Hopper & Strebe LLP, we frequently observe similar issues in contested custody cases throughout Sacramento, Placer, and El Dorado Counties. The following list outlines common high-risk behaviors, their negative judicial impact, and safer alternatives.
1. Turning the Child Into a Messenger
When a parent uses the child to relay blame, threats, scheduling complaints, or legal arguments, it tells the court that adult conflict is spilling into the child’s daily life, which is rarely viewed well. Keep parent-to-parent communication direct, brief, and in writing, and never force your child to serve as a go-between.
2. Bad-Mouthing the Other Parent
Judges don’t expect co-parents to like each other. However, they do expect parents to avoid dragging their child into the conflict. Repeated insults, sarcasm, or coaching a child to reject the other parent can all undercut credibility. If you feel the need to raise concerns, do so through your counsel, mediation, or a documented request to the court instead of through your child.
3. Blocking Parenting Time Without a Court Order
Emergencies or scheduling conflicts are one thing, but if one parent simply decides that the other doesn’t deserve time with the child and starts withholding contact, it can look like interference rather than protection. Follow the current court order as written and seek a modification if circumstances have changed.
4. Ignoring Existing Orders
Skipped exchanges, missed deadlines, unpaid obligations, or failure to follow temporary custody terms can make a parent look unstable or dismissive of the court. Compliance is therefore vital. You can request relief if needed, but don’t disregard or contradict the court’s orders.
5. Creating a Digital Record That Hurts You
Texts, emails, social media posts and comments, photos, and direct messages can all become evidence — setting your profile to private doesn’t guarantee privacy once litigation is underway. Assume that every message may be read by a judge later, and choose your words carefully.

6. Displaying Substance Abuse or Other Concerning Conduct
A custody case gets more serious when alcohol or drug abuse, reckless behavior, or lax supervision becomes part of the record. Child safety is a core part of California’s custody framework, and courts can impose restrictions or supervised contact when needed.
7. Handling Domestic Violence Allegations Poorly
When domestic violence is part of the case, the court must apply special rules designed to protect both the children and the other parent. These cases demand careful handling from the start. If you’ve been accused of domestic violence, don’t retaliate online, make sloppy counter-claims, or treat a restraining order as separate from your custody strategy.
8. Making False or Exaggerated Claims
Courts don’t look favorably on falsification. If a parent overstates facts, omits key details, or uses unfounded accusations as leverage, their actions could come back to bite them when records, witness statements, and timelines don’t line up. Speak precisely and consistently, and be prepared to back up what you say with clear documentation.
9. Failing to Support the Child Financially
Although custody and child support aren’t the same issue, judges take note of whether parents are acting responsibly. A history of nonpayment, avoidance, or indifference to the child’s material or financial needs can affect how the court views a parent’s priorities and general stability.
10. Exposing the Child to New Risk
Bringing the child around volatile partners, ongoing drug use, criminal behavior, or chaotic living conditions can quickly raise serious safety concerns. When making various decisions, try to imagine what a neutral outsider would think of the child’s living situation, the people involved, and the routines in place.
How Evaluators and Judges Assess Risk

In high-conflict custody disputes, the court may rely on more than just what each parent says in their formal declarations. The record may include school attendance, medical records, police reports, restraining-order filings, witness statements, and digital communication logs.
This matters because custody cases are often won or lost through consistency. The parent whose records, conduct, and communication all point in the same direction usually has the stronger position in court.
How to Strengthen Your Custody Case Moving Forward
Strong custody cases tend to be well-organized, internally consistent, focused on the child, and easy for a judge to follow. You can use the following checklist to assess the merits of your case and improve your chances of success:
- Follow every court order, including terms for communication, exchanges, and holiday visits.
- Keep communication with the other parent brief, polite, and centered around the child.
- Document your parenting time with details like dates, times, events, and factual observations.
- Show up for school events, medical appointments, and activities when appropriate.
- Never discuss the litigation process with your child.
- Resist the urge to post about your case online.
- Don’t make any major schedule changes or relocation plans without legal review.
- If domestic violence is part of the picture, get help right away and document the abuse carefully.
To put yourself on the best possible footing before your next hearing, take the time to review additional strategies for winning a child custody case.

FAQ: What Can Be Used Against You in a Custody Decision?
#faq_start
Can social media be used as evidence in a California custody case?
Yes. Posts, comments, photos, and direct messages can all become evidence if they relate to a parent’s safety, credibility, or co-parenting conduct. As such, it’s wise to treat your social media activity as something the other side may eventually put in front of the judge.
Can one angry text ruin a custody case?
Not on its own, usually. What hurts more is repeated behavior. A pattern of threats, insults, manipulation, or refusal to cooperate will carry much more weight than one isolated message.
Can a child choose which parent to live with?
Not automatically. The court may consider a child’s preference, especially if they’re mature enough to express a reasoned view, but that preference doesn’t decide the case by itself. The judge will still perform a full analysis of the child’s best interests.
What if the other parent is making false allegations?
Don’t respond out of anger, as doing so will only create more chaos. Instead, preserve all relevant texts, emails, and records. Follow the court’s orders carefully, stay off social media, and address the accusations with documentation and a clear legal strategy rather than emotion.
