Quick Answer: License versus Practice

Is a professional license marital property?

A professional license or degree is not itself marital property subject to equitable distribution under current New York law. Likewise, Nassau and Suffolk County courts on Long Island do not treat the enhanced earning capacity associated with a license or degree as marital property. A professional practice, however, may have a marital component if it was created during the marriage or increased in value through marital efforts. Its accounts receivable, equipment, ownership interest, contractual rights and legally recognized goodwill may require valuation. The classification and value of those assets depend on the facts, admissible evidence and expert analysis.

New York no longer divides a professional license’s enhanced earning capacity as marital property, but an ownership interest in the professional practice may still have divisible marital value. New York Domestic Relations Law §236 expressly excludes enhanced earning capacity arising from a license, degree or career enhancement from marital property, while permitting the court to consider a spouse’s contributions to the other spouse’s career when dividing marital property.

High Asset Divorce involving a licensed professional like a doctor, lawyer, accountant, etc. on Long Island, raises complex valuation and distribution questions under New York state equitable distribution rules. If you’re involved in a divorce with a professional, or if you are a professional about to go through a divorce on Long Island, NY, you should know how Nassau County and Suffolk County Supreme courts assess the value of medical, law, and accounting practices. This guide will help you learn whether a professional license is considered marital property, and which business valuation methods Long Island, NY courts use. It further explains how New York distinguishes a professional credential from an ownership interest in a practice, how marital and separate interests are classified, what financial components may require valuation and how courts can address the marital value without transferring operational control to an unlicensed spouse.

Key Takeaways from This Article

  • New York no longer treats a professional license, degree or the enhanced earning capacity arising from it as marital property. According to New York Domestic Relations Law §236 professional practice or ownership interest is a separate asset and may contain marital value if acquired during the marriage or if marital efforts contributed to its appreciation.
  • New York recognizes that a business or professional practice can possess goodwill, but the existence and value must be supported by evidence. New York Court of Appeals discussion of distributable goodwill
  • Common valuation approaches include income-capitalization/excess-earnings, discounted cash flow, and market comparisons. The choice of which is used depends on the practice size, records, and potential buyers.
  • Engage a forensic accountant or business valuator experienced in valuing medical accounting and legal practices. Expert testimony is typically required in Long Island NY Supreme courts.
  • Division remedies include buyouts, offsets with other marital assets, structured payments, or awarding maintenance instead of a direct split of intangible value.
  • Non-financial constraints (partnership agreements, licensing/ethical limits, client consent, and practice transferability) can materially lower valuation and affect division options.
  • Document compensation, billing, referral fees, and goodwill-building activity; premarital agreements and timing of professional development during the marriage significantly affect equitable distribution under New York state rules.

Current Law for Professional Licenses as Marital Property on Long Island, NY

In New York, professional licenses do not qualify as marital property when acquired or enhanced during the marriage even though they can influence future earning capacity. Like other businesses, to determine the value of the practice, valuation experts will analyze the practice’s goodwill, referral flows, and client lists using income-capitalization and discounted cash flow methods, and those results will drive outcomes in divorces involving professional practices and medical-practice valuation disputes on Long Island, NY .

A professional practice’s goodwill may be relevant when it represents an economic benefit that belongs to the practice rather than merely future income attributable to the professional’s continued labor. The analysis may examine whether client relationships, referral sources, workforce, recurring revenue, trade names, systems or other advantages could continue or be transferred. The extent to which the claimed goodwill depends entirely on the licensed professional’s future services can substantially affect the valuation. These questions are fact-specific and generally require expert testimony.

 

Legal Definitions and Context of Professional Licenses in Long Island Divorce

Under New York’s equitable distribution rules, property created or increased during the marriage can be considered marital property. If you provided financial support, household labor, or career sacrifices that helped your spouse establish a professional practice, that contribution may be able to be monetized. Long Island courts separate marital from separate property and weigh factors like marriage length, income disparity and contributions. Valuation techniques include comparables, excess earnings and DCF are often standard, so you should expect forensic accountants and business valuation experts to be called in for professional practice valuation in NY divorce cases.

A practice created during the marriage will generally begin with a presumption of marital ownership, regardless of whose name appears on the ownership documents. A practice owned before marriage may begin as separate property, but marital contributions or active appreciation during the marriage can create an equitable-distribution claim. Note that passive market appreciation is treated differently from appreciation attributable to either spouse’s efforts. Prenuptial and postnuptial agreements may also alter the final result.

 

New York Specifics and Implications in Professional Practice Divorce on Long Island

In O’Brien v. O’Brien (66 N.Y.2d 576, 1985), decided in 1985, the New York Court of Appeals treated the value of a medical license acquired during the marriage as marital property. New York later changed the governing statute. Domestic Relations Law §236 now provides that a court may not classify enhanced earning capacity arising from a license, degree or career enhancement as marital property subject to distribution.

The change does not make a spouse’s contributions irrelevant. A court may still consider one spouse’s direct or indirect contributions to the other spouse’s career when equitably dividing actual marital property. A separately identifiable ownership interest in a medical, legal, accounting or other professional practice may also remain subject to classification and valuation.

 

Valuation Methods for Professional Practices in Long Island Divorce

Professional practices can include many different components, not all of which will apply in every case. These can include:

  • Ownership interest
  • Cash and bank accounts
  • Equipment and furnishings
  • Accounts receivable
  • Work in progress
  • Liabilities
  • Partnership or shareholder interests
  • Contractual rights
  • Real estate owned by the practice
  • Legally cognizable goodwill
  • Compensation or distributions owed as of the relevant date

Future earnings from post-commencement labor are not automatically a divisible asset.

Depending on the facts and available evidence, valuation experts may use one or more approaches to estimate the value of a professional practice:

  1. Income (capitalization of earnings or DCF)
  2. Market comparables (practice sale multiples)
  3. Asset-based methods

Assessing Medical Practices in Long Island Divorce

Depending on the practice and the available records, a valuation expert may consider an income-based method, a market-based method, an asset-based method or a combination of approaches. The excess-earnings method has appeared in New York matrimonial cases, but its application depends on the evidence and assumptions used. No single method controls every New York divorce. The appropriate methodology depends on the nature of the practice, the governing ownership documents, historical earnings, assets and liabilities, transfer restrictions, compensation structure and the reliability of comparable-market data.

When a medical practice is assessed, experts need to quantify physician goodwill, billings, staffing, and payer mix. You must factor in Medicare exposure, non‑competes, and state licensure limits when valuing a medical practice in a Long Island divorce.

 

Valuing Legal and Accounting Firms on Long Island

When valuing a law or accounting practice, an expert may examine normalized owner compensation, recurring revenue, client concentration, referral sources, accounts receivable, workforce, contractual rights and the transferability of client relationships. The analysis must distinguish value belonging to the existing practice from income that would arise only through the professional’s future labor.

Goodwill may have value when the practice possesses an economic advantage capable of continuing independently of a particular attorney’s or accountant’s future services. Relevant considerations may include the firm’s name, staff, systems, recurring engagements, referral network and other institutional features. When revenue depends primarily on one professional’s personal reputation and continued work, that dependence may reduce the practice’s transferable value. The existence and amount of goodwill must be established through reliable evidence and expert analysis.

 

Business Structures and Divorce Implications in Nassau and Suffolk

Whether the practice operates as a sole proprietorship, partnership, professional corporation or professional limited liability company can affect ownership rights, transfer restrictions and valuation. Governing agreements, licensing rules, partner-consent provisions and contractual buyout terms may limit what can be transferred and influence the economic value of the owner’s interest.

 

When Is a Professional Practice Valued in a New York Divorce?

Under Domestic Relations Law §236(B)(4)(b), the valuation date generally must fall between commencement of the divorce action and trial. Courts have discretion to select appropriate dates for different assets. The nature of the asset and whether changes in value resulted from market forces, marital contributions or one spouse’s post-commencement efforts can affect that determination.

 

How Is the Marital Value of a Professional Practice Distributed?

Long Island courts generally avoid awarding an unlicensed spouse operational ownership of a professional practice when doing so would violate licensing, ethical or organizational restrictions. Instead, the marital value may be addressed through a distributive award, an offset against other marital property, negotiated payments or another structure that leaves the licensed spouse’s practice intact.

How Partnership, Shareholder and Employment Agreements Affect Value

Partnership, shareholder, employment and buy-sell agreements can all affect a practice’s value by restricting transfer, setting contractual buyout terms or limiting an owner’s control. A valuation expert must determine what economic effect, if any, those provisions may have. Their legal enforceability needs to be evaluated separately. 

Ethical Considerations

Professional and ethical rules can also affect the enforceability and economic significance of restrictive provisions. For example, New York’ State Bar Association’s Rules of Professional Conduct generally prohibit agreements restricting a lawyer’s right to practice after leaving a firm, except for provisions concerning retirement benefits. Medical-practice restrictions raise different contractual, professional and patient-care considerations. The governing agreement and current law should be reviewed before assigning any valuation effect to a restriction.

Impact on Future Earnings

An enforceable restriction may also affect projected revenue, referral patterns, marketability or the available pool of purchasers. A valuation expert must determine whether the provision has a measurable economic effect rather than assuming that every restrictive covenant reduces value. The enforceability of the provision is a separate legal question.

 

Protecting Your Professional Interests During Your Divorce on Long Island

As you move through your divorce settlement talks, we recommend assembling practice financials, client metrics, and partnership agreements so valuations are evidence-based. New York courts look at enterprise value, receivables, and goodwill when dividing business assets. As these things take time, it’s wise to engage a forensic accountant early. The cost and scope of a professional-practice valuation depend on the size of the practice, the quality of its records, the number of disputed issues and whether expert testimony is required.

 

Protecting Professional-Practice Assets During a Pending Divorce

Because a license itself is often treated as personal and nontransferable, you can protect your practice by preserving client continuity, complying with state licensure rules, and preventing involuntary transfers of goodwill or patient charts. During a pending divorce, one party may seek appropriate court relief when there is evidence that business assets are being transferred, concealed, wasted or encumbered. Whether temporary restraints or other relief are available depends on the facts and procedural posture of the case.

For more detail, we recommend retaining a valuator skilled in the income and market approaches, document metrics like annual collections, EBITDA, and client retention rates, and quantify goodwill in disputes. Prioritize forensic tracing of marital versus separate contributions, pursue negotiated buyouts using multipliers, and use targeted discovery to expose artificially depressed or inflated earnings figures.

Avoiding Double Counting in Professional Practice Valuation and Spousal Maintenance

A valuation of any practice may rely on some of the same earnings also considered when calculating maintenance. New York courts must determine whether using those earnings for both purposes would improperly count the same economic value twice. The result depends on the valuation method, the treatment of reasonable owner compensation, the income capitalized as business value and the income used in the maintenance analysis. Because the issue is fact-specific, the valuation expert and matrimonial attorney must coordinate their analyses.

 

Professional Licenses and Professional Practices Are Treated Differently

New York law treats a professional license differently from an ownership interest in a professional practice. A license, degree and the enhanced earning capacity arising from it are not marital property subject to distribution. A medical, legal, accounting or other professional practice may nevertheless contain marital value that must be classified and, when appropriate, valued through financial records and expert testimony. The available remedies may include a distributive award, an offset against other marital property or a negotiated payment arrangement that leaves the professional practice intact.

Frequently Asked Questions About Professional Practice Values in Long Island Divorce

Is a professional license (doctor, lawyer, accountant, etc.) treated as marital property on Long Island, New York?

Under current New York law, a court may not treat the value of enhanced earning capacity arising from a professional license or degree as marital property subject to distribution. However, a spouse’s contributions to the other spouse’s career may still be considered when dividing marital property. A professional practice or ownership interest is a separate issue and may contain marital value that requires classification and valuation.

How do Nassau and Suffolk courts value a professional practice?

There is no single valuation method required in every case. Depending on the practice and available evidence, experts may consider income-based, market-based and asset-based approaches. The analysis may address normalized compensation, accounts receivable, liabilities, tangible assets, contractual rights, ownership restrictions and legally recognizable goodwill. The court evaluates the expert evidence and must select a value grounded in economic reality.

What is the difference between personal goodwill and enterprise goodwill, and why does it matter in a Long Island divorce?

Goodwill may represent an economic advantage associated with the established practice, such as recurring engagements, staff, systems, referral sources or a trade name. Value that depends predominantly on the professional’s future labor and personal relationships may be less transferable. New York valuation is fact-specific, and the party asserting goodwill must support its existence and value with reliable evidence.

What valuation date is used for a professional practice?

Under Domestic Relations Law §236(B)(4)(b), the valuation date must generally fall between commencement of the divorce action and trial. Courts may select different dates for different assets based on their nature and the circumstances affecting changes in value. A professional practice is not necessarily valued on the separation date.

How can a non-professional spouse be compensated for the value of a professional license or practice?

When transferring ownership would be impractical, legally prohibited or inconsistent with professional rules, the marital value may be addressed through a distributive award, an offset against other marital assets or a negotiated payment arrangement. The appropriate remedy depends on the value established, available liquidity, governing agreements and the overall equitable-distribution analysis.

What practical steps should a professional take before or during divorce to preserve value and prepare for valuation?

Maintain clear financial records (billing, collections, expense ledgers), preserve client lists and referrals, document premarital contributions and any post-separation changes, and review partnership or shareholder agreements and ethical/lawyer rules that affect transferability. Early retention of a matrimonial attorney plus a forensic CPA or CVA experienced in professional practice valuation helps set strategy and evidence for the valuation process.

What unique issues arise for lawyers and doctors in Long Island, NY divorces and how can they affect valuation and division?

Law firm and medical practice rules often restrict transfers, require partner consent, or impose buy-sell provisions. Licensing boards and hospital privileges can also affect future income. For lawyers, professional conduct rules and client consent may limit selling or assigning a practice. For doctors, practice sales can trigger payer/credentialing issues. These constraints influence whether courts award monetary compensation instead of transferring interests, and they affect the buyer pool and market comparables used in legal and medical lawyer business valuation in Long Island, New York divorce cases.

Going through a divorce is never easy, but Hornberger Verbitsky made the process smooth, respectful, and solution-focused. I worked closely with attorney Anne Marie Lanni, who was outstanding in every way. She resolved conflicts with professionalism, communicated clearly and effectively, and authored an agreement that was thoughtful and fair. Her attention to detail and calm, competent approach gave me real peace of mind.

Lead attorney Rob was also fantastic—personable, friendly, and genuinely supportive throughout. He made a tough process feel manageable and always took time to check in and make sure I felt heard and supported.

The team’s commitment to a problem-solving approach, their impressive professional network, and even their supportive nature and community values really set them apart. I felt like more than just a case—I felt cared for and well-represented.

Highly recommend Hornberger Verbitsky if you want trusted guidance and a team that gets results with integrity and compassion.”
