When you work with our family lawyer in Buffalo Grove, IL, you get a team that knows how Illinois courts analyze parenting time allocations, what judges in Cook and Lake County look for in contested matters, and how to anticipate what opposing counsel is likely to argue.
Results That Matter to Real People
Our attorneys have helped clients recover millions of dollars across property division and support matters. We know that every family law case is different, as those involved in them have their own concerns, priorities, and hopeful outcomes. A high-asset divorce involving a business requires a completely different strategy than a custody modification. We’ve handled both of these situations, and everything in between.
A Firm Built Around the Full Picture
Most family law cases don’t resolve cleanly on one issue. A divorce involves property, support, and children. A custody matter can escalate into a protection order situation. We also offer an in-house divorce coach, which is an industry-first model designed to support clients through the emotional and practical dimensions of their case alongside the legal work.
What Our Clients Say
⭐⭐⭐⭐⭐
“Jaclyn has been my attorney for my divorce as well as my year long custody battle. She was great at keeping me well informed of all possible scenarios as well as explaining all the forms and steps taking place. Jaclyn knew what was in the best interest for my child and I. She put up a hard fight when needed to. If any other issues come up in the future I will most definitely be giving her a call again!” — Ashley Zachery

Types of Family Law Cases We Handle in Buffalo Grove
Buffalo Grove families come to us at all different stages of a legal matter, some before anything has been filed and others may be midway through litigation that isn’t going how they hoped. Here is a breakdown of what our attorneys handle.
- Divorce. Illinois is a no-fault divorce state, but that doesn’t make the process simple. We handle contested and uncontested divorces, including matters involving significant assets, business interests, and complex support calculations.
- Divorce mediation. Not every divorce belongs in front of a judge. Mediation can resolve disputes faster and at lower cost, but it requires proper preparation and someone in your corner who understands how to approach mediation with successful strategy.
- Child custody and parental responsibility. Illinois no longer uses the term “custody”. The law allocates parental responsibilities and parenting time separately. These determinations are based on the best interests of the child, and the factors courts weigh are specific and sometimes surprising.
- Spousal support and alimony. Whether you expect to pay or receive maintenance, Illinois uses a statutory formula as a starting point. The duration and amount can be contested, and modifications are possible when circumstances change.
- Orders of protection and domestic violence. If you need immediate protection, we move quickly to prevent further incidents of abuse or violence. We also represent individuals who have been named in an order and need to respond effectively.
- High-asset and complex divorce. Cases involving business ownership, retirement accounts, real estate portfolios, or executive compensation require a different level of financial analysis. We work with forensic accountants and other specialists when the numbers demand it.
- Prenuptial and postnuptial agreements. A well-drafted agreement protects both parties, while a poorly drafted document may not have strong grounding when it matters the most.
- Support and custody modifications. Life changes, as income fluctuates, jobs relocate, and children’s needs evolve. We handle post-decree modifications when the original order no longer reflects current circumstances.
Illinois Legal Requirements for Family Law
Illinois family law operates under the Illinois Marriage and Dissolution of Marriage Act, codified at 750 ILCS 5. Here are a few things Buffalo Grove residents should understand about state legal requirements before filing anything.
Illinois is a no-fault state. The only ground for divorce is “irreconcilable differences,” and there is no requirement to prove fault or misconduct to obtain a dissolution. That said, marital misconduct, particularly financial misconduct like dissipation of assets, can still affect how the court divides property.
Residency requirements. At least one spouse must have been a resident of Illinois for 90 days before a judgment of dissolution can be entered under 750 ILCS 5/401.
Parenting best interests standard. Decisions are governed by the best interests standard under 750 ILCS 5/602.7, which directs courts to evaluate more than a dozen factors, everything from each parent’s relationship with the child to the willingness of each parent to facilitate a relationship with the other.
Spousal maintenance calculation. Spousal maintenance is calculated under 750 ILCS 5/504, using a formula based on both spouses’ gross incomes, though the court retains discretion to deviate based on the specific facts of a case. Understanding which statutes apply to your situation and how courts have interpreted them, changes your options significantly.
Orders of protection. In family law matters, the Illinois Domestic Violence Act of 1986 provides both emergency and plenary protection options. If you are concerned about your safety as a family law case is proceeding, we urge you to contact our team now for the protection you need.
Important Aspects of a Buffalo Grove Family Law Case
Property Division
Illinois divides marital property under an equitable distribution standard, which does not mean equal. Courts weigh each spouse’s contribution to the marital estate, the duration of the marriage, the economic circumstances of each party, and several other factors. What counts as marital property versus non-marital property is frequently disputed, and the difference matters enormously. Inheritances, gifts, and pre-marital assets can retain their non-marital character, but only if they haven’t been commingled. We can discuss marital vs. non-marital property and how Illinois courts categorized your assets and belongings.
Parenting Time and Responsibility Allocation
Courts in Illinois distinguish between decision-making authority over major issues like education, healthcare, and religion, and the physical schedule of where the child lives. A parent can have significant parenting time without having sole decision-making authority, and vice versa. Disputes over parenting plans are often the most emotionally charged part of any case. Our attorneys approach these matters with that reality in mind. If you’re building or modifying a parenting plan, the factors courts consider are detailed and case-specific.
Spousal Maintenance
Maintenance in Illinois is not automatic, as the formula under the statute applies when both spouses’ combined gross income is under $500,000 and no undue hardship would result. But even when the formula applies, the duration of payments depends on how long the marriage lasted. Longer marriages can result in indefinite maintenance, while shorter marriages produce time-limited awards. And when income changes after a divorce, support modifications are possible but require proving a substantial change in circumstances.
High-Conflict Dynamics
Some cases don’t resolve because one party is using the process itself as leverage. Delayed disclosures, dissipation of assets, and refusal to comply with court orders are all patterns we’ve seen and addressed. When the other side isn’t acting in good faith, knowing how to document it and use it effectively in court makes a real difference. Our attorneys don’t flinch when cases get contentious, as we know that’s when preparation and strategy matter most.
Post-Decree Enforcement
A court order is only useful if it’s followed. When an ex-spouse ignores a parenting plan, withholds support, or violates an agreed property division, we pursue enforcement through contempt proceedings. We can let you know what to do when your ex ignores court orders and the options available under Illinois law.

Family Law Statistics in Buffalo Grove, IL

How Do Family Law Cases Work in Illinois?
Family law covers far more than divorce. Illinois handles several distinct types of cases, each with its own rules and process. Here’s a plain look at how the main ones work.
- Divorce, or dissolution of marriage. This ends a marriage and resolves property, support, and parenting in one case. Illinois is a no-fault state, so neither spouse has to prove wrongdoing. Recognizing when legal help makes sense early can keep a straightforward case from going sideways, and our Buffalo Grove family lawyer is just one call away.
- Allocation of parental responsibilities. Illinois replaced the word custody with two separate things: parenting time and decision-making. Courts decide based on the child’s best interests, weighing stability, each parent’s role, and more. We advocate for a father’s rights as forcefully as a mother’s, because the law favors neither by default.
- Child support. Illinois calculates support using both parents’ incomes under an income-shares model. The amount isn’t fixed forever. When income or a child’s needs change, either parent can ask to modify child support, and enforcement tools exist when payments stop.
- Spousal maintenance. Not every divorce includes maintenance. When it applies, Illinois uses guidelines tied to both incomes, and how long payments last depends largely on the length of the marriage. The facts of each case can shift the result.
- Orders of protection. When abuse or threats are involved, a person can ask the court for an order that restricts contact and conduct. These can be entered quickly on an emergency basis and then extended after a hearing. We handle an order of protection from either side, the petitioner or the respondent.
- Modifications and enforcement. Family orders aren’t always the last word. When circumstances genuinely change, you can ask to modify a parenting plan or a support order. When an ex ignores an order, the court can enforce it through contempt proceedings.
Buffalo Grove Family Law Lawyer FAQs
What Does a Family Lawyer Handle?
Our Buffalo Grove family lawyer handles divorce, parental responsibilities and parenting time, child and spousal support, orders of protection, parentage for unmarried parents, and post-decree changes. Some matters, like second-parent adoptions, also fall under family law. The common thread is the legal side of family relationships.
How Are Parenting Time and Responsibilities Decided?
Illinois courts use the best-interests standard, looking at each parent’s relationship with the child, stability, and willingness to support the other parent’s role. In contested cases, the court can appoint someone to represent the child’s interests directly. The focus is the child’s welfare, not either parent’s preference.
How Is Child Support Determined in Illinois?
Illinois uses an income-shares model that accounts for both parents’ incomes and the parenting schedule. Support can also address add-ons like medical costs and, in some cases, college costs. Orders can be reviewed and adjusted when circumstances change, which our Buffalo Grove family attorneys can help with.
Do Grandparents Have Visitation Rights?
Sometimes. Illinois lets grandparents and certain others petition for visitation in limited situations, usually when a parent has died, is absent, or unreasonably denies contact, and when it serves the child. Grandparents’ rights are narrower than parents’ rights, and courts apply the standard carefully.
How Do I Get an Order of Protection?
You petition the court, which can grant an emergency order quickly and a longer one after a hearing. The order can address contact, the home, and parenting time. Knowing who can file for protection and what evidence helps makes the process smoother.
Can I Change My Name in a Family Case?
Often, yes. A spouse can ask to restore a former name as part of a divorce, while name changes for children follow a separate, more involved process. We can explain how a name change works in your situation.
How Does Co-Parenting Work After a Case?
Once a parenting plan is in place, both parents follow the schedule and the decision-making split it sets out. Steady co-parenting reduces conflict and helps children adjust. When a parent repeatedly violates the plan, the court can step in.
How Much Does a Family Lawyer Cost in Buffalo Grove?
It depends on the matter. An uncontested case costs far less than a contested custody or support fight. Complexity, conflict, and whether outside professionals are needed all factor in. We give you a realistic estimate based on your circumstances during a consultation with our Buffalo Grove family lawyer.
Do Unmarried Parents Have Rights?
Yes. When parents aren’t married, legal parentage has to be established before custody and support rights apply. Once parentage is confirmed, an unmarried parent has the same access to parenting time and responsibilities as any other parent.
Do I Really Need a Family Lawyer?
Not every matter requires one, but family cases carry long-term consequences for your finances and your children. Our Buffalo Grove family lawyer protects your rights, keeps the paperwork clean, and helps you avoid mistakes that are hard to undo later.
