Parenting disputes are often one of the most emotional parts of a divorce or separation. When disagreements arise over parenting time or decision-making responsibilities, it's understandable for emotions to run high. However, the choices you make during a custody case can have a lasting impact on both your legal position and your child's well-being.

Illinois courts make parenting decisions based on the best interests of the child, not which parent is more emotional or outspoken. Parents who remain focused on their child's needs, communicate respectfully, and comply with court orders are generally in a stronger position throughout the legal process.

If you're involved in a custody dispute, understanding the most common mistakes can help you avoid unnecessary conflict while protecting your parental rights.


Letting Emotions Control Your Decisions

Divorce and parenting disputes naturally bring feelings of frustration, sadness, and uncertainty. However, reacting emotionally instead of thoughtfully can make resolving parenting issues much more difficult.
Examples include:

  • Sending angry text messages or emails
  • Arguing during parenting exchanges
  • Making impulsive legal decisions
  • Refusing reasonable communication
  • Using your child to express frustration

Before responding during a disagreement, take time to consider whether your actions support your child's best interests.

Remaining calm and respectful often leads to more productive communication and better long-term outcomes.


Speaking Negatively About the Other Parent

One of the most damaging mistakes parents make is involving their children in adult conflicts.

This may include:

  • Criticizing the other parent
  • Blaming the other parent for the divorce
  • Asking children to take sides
  • Discussing court proceedings
  • Using children to deliver messages

Whenever appropriate, Illinois courts encourage children to maintain healthy relationships with both parents.

Keeping adult disagreements separate from your child's daily life helps reduce emotional stress and demonstrates your commitment to effective co-parenting.


Ignoring Court Orders or Parenting Agreements

Temporary parenting schedules and court orders are legally enforceable.

Common mistakes include:

  • Returning children late
  • Skipping scheduled parenting time
  • Canceling visits without valid reasons
  • Making important parenting decisions without consulting the other parent when required

If your circumstances change, it's usually better to request a formal court modification rather than simply ignoring an existing order.

Following court orders demonstrates reliability, responsibility, and respect for the legal process.


Posting About Your Custody Case on Social Media

Many parents underestimate how social media can affect a family law case.

Avoid posting:

  • Complaints about the other parent
  • Details about your court case
  • Financial disputes
  • Photos intended to embarrass someone
  • Emotional comments made during disagreements

Even posts shared privately may later become evidence in court.


Expert Insight

Deleting a social media post doesn't necessarily make it disappear. Screenshots, saved messages, and archived content may still be available. Before posting anything related to your family or legal dispute, ask yourself whether you'd be comfortable explaining it to a judge.


Failing to Keep Good Records

Good documentation can be extremely valuable during a parenting dispute.

Consider keeping records of:

  • Parenting schedules
  • School communications
  • Medical appointments
  • Important emails and text messages
  • Missed parenting exchanges
  • Significant events involving your child

Organized records often provide stronger evidence than relying on memory months later.


Putting Personal Conflict Before Your Child's Needs

Children often experience significant stress during divorce.

Parents can help reduce that stress by:

  • Maintaining consistent routines
  • Supporting school attendance
  • Encouraging healthy relationships with both parents
  • Avoiding unnecessary arguments
  • Listening to their child's concerns

Illinois courts generally look favorably upon parents who demonstrate flexibility, cooperation, and a genuine commitment to their child's well-being.


Waiting Too Long to Seek Legal Advice

Many parents hope parenting disagreements will resolve on their own.

Unfortunately, delaying legal guidance may allow misunderstandings to become larger disputes.

Early legal advice can help you:

  • Understand your parental rights
  • Avoid common legal mistakes
  • Organize important documentation
  • Prepare for negotiations
  • Develop realistic expectations

Even if your case is ultimately resolved through mediation or negotiation, understanding the legal process early often leads to better decision-making.


Focus on Cooperation Whenever Possible

Not every parenting disagreement needs to end up in court.

When parents communicate respectfully and work together, they often experience:

  • Less conflict
  • Lower legal costs
  • Faster resolutions
  • Greater flexibility
  • Healthier long-term co-parenting relationships

While cooperation isn't always possible, maintaining a child-centered approach can often benefit both parents and, most importantly, the children involved.


Frequently Asked Questions

What is the biggest mistake parents make during custody disputes?

One of the most common mistakes is allowing emotions to drive decisions instead of focusing on the child's best interests. Courts generally favor parents who demonstrate cooperation, stability, and a willingness to support healthy parenting relationships.


Can social media affect my custody case?

Yes. Social media posts, comments, photos, and messages may be introduced as evidence during family law proceedings. It's generally best to avoid discussing your case online.


Should I follow a temporary parenting order?

Yes. Temporary court orders are legally binding unless modified by the court. Ignoring them could negatively affect your custody case.


Is it appropriate to discuss the custody case with my child?

Generally, no. Children should not be placed in the middle of legal disputes or asked to choose between parents.


When should I contact a family law attorney?

It's often beneficial to seek legal guidance as soon as parenting disputes arise. Early advice can help you understand your rights and avoid mistakes that may affect your case.

Anyone paying for groceries, insurance, housing, or medical care knows that the cost of living has increased. But does inflation—or simply spending more money than you did when you divorced—automatically allow you to return to court and seek more maintenance? A recent Illinois appellate decision says no . The important question is not simply whether expenses have increased. The party seeking modification must show that the change has substantially affected his or her financial needs . In In re Marriage of Tompkins, 2026 IL App (3d) 250482-U , the Illinois Appellate Court, Third District, affirmed the dismissal of a former wife's request to increase maintenance because she had not alleged sufficient facts demonstrating a substantial change in circumstances. There is one important qualification: Tompkins is a Rule 23 order , designated by the “-U” in its citation. It therefore is not precedential except in the limited circumstances permitted by Illinois Supreme Court Rule 23(e)(1). Nevertheless, it provides a useful recent illustration of how Illinois courts approach requests to modify maintenance. What Happened in Tompkins? When John Tompkins and Amy Itoku divorced in 2019, their marital settlement agreement recognized that John's income as a self-employed portfolio manager fluctuated. The parties therefore created an unusual maintenance formula. Amy received a $6,500 monthly draw, followed by an annual “true-up” based upon John's actual income. Their agreement contained a detailed schedule specifying the percentage Amy would receive at various income levels, including income exceeding $4 million. Years later, Amy sought to modify maintenance. Among other things, she alleged that: John had gone from self-employment to salaried employment; his income had increased dramatically; her medical expenses had increased by approximately $10,000 per year; and because of uncertainty concerning her maintenance payments, she had reduced expenditures for vacations, health-club memberships, vehicles, streaming services, and household help. The trial court dismissed her petition, and the appellate court affirmed. A Change in Expenses Is Not Necessarily a “Substantial Change” Illinois law provides that a maintenance award may be modified or terminated “only upon a showing of a substantial change in circumstances.” 750 ILCS 5/510(a-5). The statute then directs the court to consider factors including changes in employment, earning capacity, income, property, the recipient's efforts to become self-supporting, and other equitable circumstances. The appellate court in Tompkins emphasized an important distinction: life circumstances can change without financial need changing substantially enough to justify modifying maintenance. The court explained that a substantial change generally requires a change in either: the needs of the spouse receiving maintenance; or the paying spouse's ability to pay. Amy alleged increased medical expenses and that she had cut back her lifestyle. But she did not allege that those changes left her unable to meet her expenses, that her financial needs had materially increased, or that the maintenance she was receiving was inadequate to meet those needs. The court therefore held that those allegations, standing alone, were insufficient. That distinction is important. It is not enough to say: “Everything costs more now.” The stronger case is: “My necessary expenses have materially increased, here are the numbers showing the increase, and my present income and maintenance are no longer sufficient to meet those needs.” What About the Paying Spouse Earning More Money? Tompkins also illustrates another important limitation. Amy alleged that John's income had increased dramatically after the divorce. Ordinarily, a significant increase in the payor's income is one of the factors a court considers under section 510(a-5). But the parties' MSA had specifically anticipated both different forms of employment income and income levels exceeding $4 million. The appellate court concluded that the agreement already addressed the circumstances upon which Amy relied. This issue must be considered together with the current version of section 510(a-5). Illinois law now provides that the foreseeability or contemplation of a future event generally cannot be used to defeat a claim of substantial change unless that future event was expressly specified in the court order or agreement incorporated into the judgment. 750 ILCS 5/510(a-5) . That makes careful drafting of marital settlement agreements increasingly important. If the parties want a particular future event—retirement, changes in compensation, receipt of bonuses, or another defined circumstance—to be treated in a particular way, the agreement should say so expressly. Does Tompkins Mean Inflation Never Matters? No. The case should not be read as creating a blanket rule that inflation or increased costs can never support modification of maintenance. What Tompkins demonstrates is that merely identifying increased expenses or reduced discretionary spending is not enough. The moving party must connect those circumstances to a material change in actual financial need. That distinction is also important because child support cases are different. Illinois courts have long recognized that children's needs may increase as they grow older and as the cost of living rises. The First District recently repeated that principle in In re Marriage of Cox , 2026 IL App (1st) 242290, ¶ 52 , citing In re Marriage of Sweet, 316 Ill. App. 3d 101, 105 (2000). So Tompkins should not be generalized into a rule that inflation is irrelevant to every form of support. The Practical Lesson A former spouse considering a maintenance modification should not rely simply upon inflation, higher prices, or a comparison of today's expenses with expenses from several years ago. A persuasive petition should identify specific, material changes and explain their financial consequences. That usually means comparing income, necessary expenses, health costs, employment circumstances, assets, and financial resources at the time of the prior order with those circumstances today. The lesson of Tompkins is fairly straightforward: a higher cost of living may explain why someone spends more money, but the court still needs facts showing that the person's financial need has substantially changed. And before filing, the marital settlement agreement itself should be reviewed closely. Sometimes the parties have already agreed how the very change now being complained about will affect maintenance.

Divorce is one of the few legal matters where a decision made today can affect your finances, your children, and your family relationships for years to come. That is why choosing a divorce attorney based primarily on hourly rate can be a costly mistake.  A lower hourly rate may seem attractive at the beginning of a case. But divorce litigation is not simply a matter of filling out forms, exchanging financial documents, and appearing in court. The difficult cases require judgment—knowing which issues matter, which do not, when to negotiate, when to litigate, and how a decision made early in the case may affect the final result. That judgment usually comes from experience.

Illinois has passed a new child-support law, Public Act 104-0733, which takes effect on January 1, 2027. The law changes sections 505 and 510 of the Illinois Marriage and Dissolution of Marriage Act. Its biggest changes involve shared parenting time, low-income support orders, incarcerated parents, and the exchange of income information. The new law does not automatically change every existing child-support order. A parent will generally still need a legal basis to modify an existing order. The fact that Illinois changed the law is not, by itself, enough to reopen an old support order.

Not necessarily. In fact, it happens more often than people think. At LSR Family Law Group, many of our clients come to us after previously hiring one — and sometimes more than one — divorce lawyer. That does not automatically mean the client is difficult, unreasonable, or the problem. Divorce is one of the most stressful events a person can go through. The lawyer-client relationship in a divorce case requires trust, communication, honesty, and a plan that makes sense for that client’s life. Sometimes that relationship simply breaks down. One of the most important things a divorce lawyer can do is listen. Really listen. Every client comes into a divorce case with their own concerns, fears, priorities, and goals. Some are worried about their children. Some are worried about financial survival. Some are concerned about protecting a business, a home, retirement, or their reputation. Others just want the conflict to end. There is no one-size-fits-all divorce strategy. A good plan has to be custom tailored to the client, the facts, the law, and the realities of the courtroom. That also means having tough conversations when necessary. Sometimes a client’s goals do not line up with the facts of the case or what Illinois law allows. When that happens, the answer is not to ignore the problem, overpromise, or tell the client only what they want to hear. The better approach is to explain the legal landscape clearly, discuss the risks, and help the client develop realistic goals that can actually be pursued. Those conversations are not always easy. But they build trust. Many divorce firms do not take enough time to listen to the client, understand what matters most, or help the client develop a realistic strategy. When clients feel unheard, confused, or surprised by what is happening in their case, dissatisfaction grows. Eventually, trust and confidence break down. That is often when the client decides to make a change. Hiring a new lawyer during a divorce is not something most people do lightly. It usually means the client knows something is not working and wants a better path forward. At LSR Family Law Group, we understand that. We do not assume that a client who had prior counsel is the problem. We start by listening, learning the history of the case, identifying what went wrong, and building a plan designed around the client’s goals and the realities of the case. Sometimes a fresh start with the right lawyer makes all the difference.

While traditionally mothers were favored in custody disputes, as a father, you do have rights to your child. Following are 10 tips for fathers in a divorce case to learn how to protect yourself. Think carefully before leaving your home when you decide to divorce: If you leave your home and children, it may be more difficult for you to negotiate to either get the home back or get access to your children back on a full-time basis. Keep careful records of who cares for your child: While mothers have long been favored in custody disputes, trends may change as fathers take on more of the role of caregivers. In some cases, fathers are the primary caregivers in fact. If you are very involved in the day-to-day care of your child, that may impact the custody agreement the judge determines is appropriate. Collect evidence of paternity as soon as possible: If you believe paternity is going to be questioned, get a copy of your child’s birth certificate and/or of any other evidence that you have that shows you are the child’s father Request a DNA test if there is a dispute: While this doesn’t come up as often in marriage dissolution, paternity can still be disputed at times during custody cases. You may wish to consider getting a paternity test if you believe your ex-wife will question whether you are really the child’s father. Always pay child support as mandated: It may be tempting to withhold child support if your spouse is preventing you from seeing your child, but doing so can make you susceptible to a court order or contempt of court. It can also hurt your rights in a custody case. Comply with court orders and don’t break any laws- While you may not be happy if you are initially granted limited visitation, make sure to comply with all court rules. Don’t take your child from the state without permission or do anything else that might be illegal, as this can land you in jail and can make it hard for you to get custody. Hire an attorney experienced in protecting father’s rights: Your divorce attorney should have specifically worked with fathers before and should have experience in custody fights. Secure witnesses who can attest to your care of the child: If you and your spouse really can’t agree and the court has to decide on custody, the judge may request you call witnesses who can testify to your parenting skills. Ask people to be witnesses on your behalf early. Neighbors, teachers and other caregivers may all be able to tell the court how good a father you are, making it more likely you will be treated favorably in a custody dispute. Understand the custody arrangements and laws available: Each state has different rules and laws, but there are some common types of custody arrangements such as joint custody or partial custody. Understand the language as far as what each type of custody arrangement means. Do not agree to anything you don’t think is fair unless the court mandates you do so: While you may want to just end the custody battle, especially if it drags on for a long time, don’t give up custody of your child without a fight.
