Child support can have a substantial impact on both a child’s financial well-being and a parent’s finances.
Whether you are seeking child support, responding to a support request, attempting to modify an existing order, or dealing with unpaid child support, it is important to understand how the law applies to your family’s circumstances.
At The Law Offices of Jeffrey N. Markowicz, I represent parents in child support matters throughout New York, Washington, D.C., and Maryland.
I have more than 25 years of legal experience handling divorce, child custody, child support, visitation, and other family law matters. I work directly with my clients to understand their income, parenting arrangement, financial obligations, and their children’s needs before developing a strategy.
Child support laws and calculation methods differ significantly between New York, Washington, D.C., and Maryland. My multijurisdictional family law practice provides valuable experience for families whose lives, employment, assets, or children have connections to more than one jurisdiction.
Schedule a confidential consultation with me to discuss your child support matter.

Child support is money paid to help meet a child’s financial needs when parents do not live together or otherwise require a formal support arrangement.
Depending on the jurisdiction and circumstances, child support may help cover expenses such as:
Both parents generally have a financial responsibility to support their children.
A child support order determines how that responsibility will be allocated under the laws of the jurisdiction hearing the case.
Child support is not simply an amount one parent chooses.
New York, Washington, D.C., and Maryland each use statutory guidelines or formulas to calculate child support.
Although the specific formulas differ, calculations may consider factors such as:
The guideline calculation is often a starting point, not the end of the analysis.
Cases involving high incomes, business ownership, irregular compensation, or unusual expenses can require additional financial analysis.
Online calculators can provide estimates, but they may not identify every issue that affects a support order.
As a child support lawyer, I can help determine:
Small differences in income calculations can produce significant differences over the life of a support order.
Understanding the underlying numbers is therefore critical.
A child support order may be established as part of:
Parents who were never married may still have the same fundamental obligation to financially support their children.
Where legal parentage has not been established, that issue may need to be resolved before or as part of the child support proceeding.
I represent parents seeking support and parents responding to support claims.
Child support is frequently addressed as part of a divorce involving minor children.
The parents may simultaneously need to resolve:
Because these issues overlap, consider child support as part of the broader family and financial picture.

Child custody and child support are related, but they are separate legal issues.
Custody covers parental decision-making and where children live.
Child support addresses financial responsibility.
The parenting arrangement may affect the support calculation, particularly in jurisdictions that incorporate the time children spend with each parent into the guidelines.
However, parents should not treat custody as a financial tool to increase or decrease support.
Custody decisions should focus on the child’s best interests.
Learn more about Child Custody.
Parents sometimes assume that a disagreement over child support allows them to withhold parenting time or that denied visitation allows them to stop paying support.
These are generally separate obligations.
If a parent fails to pay court-ordered support, enforcement remedies may be available.
If a parent interferes with court-ordered parenting time, custody or visitation remedies may be available.
Parents should generally seek appropriate legal relief rather than violating another court order.
Learn more about Visitation & Parenting Time.
Income can become one of the most disputed issues in a child support case.
For a traditional salaried employee, income may be relatively straightforward to identify.
For others, compensation may include:
The exact definition of income depends on the jurisdiction.
A parent’s tax return may be important evidence, but taxable income and income used for child support purposes are not always identical.
I review each case’s financial circumstances to determine whether the income used to calculate support accurately reflects the parent’s financial situation.
Child support calculations can become substantially more complicated when one or both parents own a business.
A business owner may receive financial benefits through:
Business tax returns may contain deductions that are legitimate for tax purposes but require additional analysis in a family law case.
Questions may also arise when a parent’s current reported income differs substantially from historical earnings.
Depending on the circumstances, you may need to review financial records beyond a personal tax return.
These can include:
When substantial business income is involved, careful financial analysis can be critical.
High-income child support cases present their own set of challenges.
A parent may earn substantial income through:
Once parental income exceeds levels addressed directly by a state’s standard guideline formula, courts may have additional discretion in determining an appropriate support obligation.
The child’s actual needs, standard of living, and other statutory factors may become important.
For high-income parents, determining the correct income figure and understanding how the applicable jurisdiction treats income above guideline thresholds can make a substantial financial difference.
My work in both high net worth divorce and complex family law matters allows me to consider these issues as part of the family’s broader financial circumstances.

Not every parent earns the same amount each month.
Sales professionals, executives, financial professionals and business owners may receive compensation that changes significantly from year to year.
Variable income can include:
Determining the appropriate child support amount may require reviewing multiple years of compensation rather than focusing on a single paycheck.
The appropriate approach depends on the applicable law and facts of the case.
Childcare can represent a high cost for working parents.
Child support proceedings may need to address expenses such as:
How these expenses are treated depends on the jurisdiction and circumstances.
Parents should retain documentation showing actual childcare expenses when those costs are relevant to the support calculation.
A child support order may also address healthcare costs.
These can include:
The order should clearly explain how the parents will share these responsibilities.
Families may also need to address expenses beyond basic child support.
Depending on the jurisdiction and circumstances, disputes may involve:
These costs can become particularly significant in high-income families.
Clear agreements on who pays for which expenses can help reduce future disputes.
A child support order that was appropriate several years ago may no longer reflect the family’s current circumstances.
A parent may seek to increase or decrease child support after a significant change.
Potential reasons for modification may include:
Modification is not necessarily automatic.
The parent requesting a change generally must follow the applicable legal procedure and meet the jurisdiction’s requirements.
Waiting to request a modification can also have financial consequences because courts may be restricted in how far back they can adjust an existing order.
I represent parents seeking modifications as well as parents opposing requested changes.
Losing employment does not automatically terminate an existing child support order.
Until the order is formally modified, the existing obligation may continue.
A court may examine:
If your income has materially changed, obtaining legal advice promptly can be important.
Waiting while arrears accumulate can make the situation substantially more difficult.
When a parent fails to pay court-ordered child support, enforcement proceedings may become necessary.
Depending on the jurisdiction and circumstances, enforcement mechanisms can include:
The exact remedies available depend on the jurisdiction.
I represent parents seeking payment of past-due child support as well as parents accused of failing to comply with an existing order.
Past-due child support is commonly called arrears.
Arrears can accumulate when a parent:
If you believe support has not been paid, accurate payment records can become important evidence.
If you owe arrears, ignoring the problem generally makes it worse.
I can review the existing order, payment history, and circumstances to determine what options may be available.
Parents can often negotiate financial terms as part of divorce or custody settlements, but child support remains subject to the laws and requirements of the applicable jurisdiction.
An agreement should clearly address:
Simply agreeing verbally that neither parent will seek child support may not resolve the issue permanently.
Because child support concerns a child’s financial needs, courts may retain authority over support even after parents reach an agreement.
Parents pursuing an uncontested divorce still need to address child support appropriately.
A complete settlement may need to establish:
Addressing these issues clearly can help prevent an otherwise amicable divorce from turning into a future financial dispute.

I have been licensed to practice law in New York since 2007 and represent parents in New York child support matters.
New York applies the Child Support Standards Act when determining child support.
The calculation generally begins by determining parental income and applying statutory percentages based on the number of children.
The standard percentages are:
The court generally allocates the resulting obligation between parents based on their respective shares of combined parental income.
Additional expenses may include childcare, healthcare, and certain educational costs.
For income exceeding the statutory cap, additional legal analysis may be required to determine what support is appropriate.
New York generally requires parents to financially support a child until age 21, although circumstances involving emancipation can affect that obligation.
I represent New York clients in:
New York Office

Suite 2327
New York, NY 10006
I have been licensed in the District of Columbia since 2001 and represent parents in Washington, D.C. child support matters.
D.C. courts use a Child Support Guideline when calculating support.
The calculation may consider factors including:
Even when a child spends substantial time with both parents, child support may still be appropriate depending on the parents’ respective incomes and circumstances.
In Washington, D.C., child support generally continues until age 21, subject to circumstances that may affect the obligation.
I represent D.C. clients in:
Washington, D.C. Office
700 12th Street NW
Suite 700
Washington, D.C. 20005
I have been licensed to practice law in Maryland since 1999 and represent parents throughout Maryland in child support matters.
Maryland uses child support guidelines when determining an appropriate support obligation.
The calculation can involve factors such as:
Maryland’s calculation can differ depending on the parenting arrangement.
For families with substantial incomes, business ownership, or complicated compensation, determining the appropriate support obligation may require analysis beyond a basic online calculator.
In Maryland, the age of majority is generally 18. A child who turns 18 while still enrolled in secondary school may continue to have a right to parental support until graduation, leaving secondary school, emancipation, marriage, death, or age 19, whichever applicable event occurs first.
I represent Maryland clients seeking to establish, modify, or enforce child support orders.
Child support issues can become more complicated when parents live in different jurisdictions.
For example:
Questions may arise regarding:
My multijurisdictional practice can be particularly valuable when a child support matter involves New York, Washington, D.C., and Maryland.
Child support cases are heavily dependent on financial information.
Documents that may be useful include:
The documents needed will depend on the circumstances of your case.
I have practiced law since 1999 and have handled child support, custody, divorce, visitation, domestic violence, and other family law matters throughout my career.
I have been licensed in:
This is particularly valuable for families whose financial or parenting circumstances cross jurisdictional boundaries.
Not every child support case involves two straightforward salaries.
Business ownership, substantial income, investments, bonuses, and executive compensation can make determining income more complicated.
My experience handling high net worth divorce and other complex matrimonial matters allows me to examine child support as part of the family’s broader financial picture.
When child support disputes cannot be resolved through agreement, I am prepared to advocate for my client’s position in court.
My litigation background extends beyond family law and includes a broad range of civil and criminal cases.
Clients work directly with me.
I review the case’s financial circumstances, explain the applicable law, and help clients understand the immediate and long-term implications of a proposed support order.
The calculation depends on the jurisdiction. New York, Washington, D.C., and Maryland each use guidelines that consider parental income and other factors. Childcare, healthcare, and parenting arrangements may also affect the final amount.
Yes. How much each parent’s income affects the calculation depends on the jurisdiction and the applicable formula.
Not necessarily. Shared parenting time does not automatically eliminate child support. Differences in parental income and the applicable state formula may still result in one parent paying support.
Potentially. A parent may request modification when the requirements of the applicable jurisdiction are satisfied, such as after a significant change in income, employment or custody.
Possibly, but job loss does not automatically change an existing court order. A formal modification may be necessary. Act promptly if your financial circumstances materially change.
Potentially. Whether an increase justifies modification depends on the jurisdiction, existing order, and circumstances.
They may be. Bonuses, commissions, and other compensation can be relevant when determining parental income.
The analysis may require review of business income, compensation, distributions and financial records. A personal tax return may not provide the complete financial picture.
Child support orders can include healthcare and health insurance expenses. The way those expenses are allocated depends on the jurisdiction.
Childcare expenses can affect support calculations, particularly when care is required so a parent can work or pursue qualifying education or employment activities.
Generally, no. Parenting time and child support are separate legal obligations. If visitation is being denied, you may be able to pursue enforcement of the parenting order.
Generally, unpaid child support does not by itself authorize a parent to disregard an existing custody or visitation order.
New York generally requires parents to support their children until age 21, subject to circumstances such as emancipation and other legal exceptions.
Child support in Washington, D.C. generally continues until a child reaches age 21, although the particular circumstances and existing order should be reviewed.
Maryland support generally extends to age 18, but support may continue for an 18-year-old who remains enrolled in secondary school until an applicable terminating event, including graduation, leaving school or reaching age 19.
Unpaid child support can result in arrears and enforcement proceedings. The available enforcement measures depend on the jurisdiction and circumstances.
Parents may reach agreements regarding support, but courts retain authority over child support and must apply the jurisdiction’s laws. A private agreement does not necessarily eliminate a parent’s legal support obligations.
Yes. I represent parents seeking appropriate child support as well as parents responding to child support requests, modifications and enforcement proceedings.
Yes. I represent family law clients in all three jurisdictions and have been licensed in Maryland since 1999, Washington, D.C. since 2001, and New York since 2007.
The amount of child support ordered today can affect your family’s finances for years.
Whether you are establishing support for the first time, dealing with a high-income calculation, requesting a modification, or facing an enforcement proceeding, understanding the law and the numbers behind the calculation is essential.
I represent parents in child support matters throughout New York, Washington, D.C., and Maryland.
I work directly with clients to review their financial circumstances, explain how the applicable child support laws may affect them, and develop a strategy focused on reaching an appropriate result.
