Divorcing a Doctor, Lawyer, etc? How to Value Professional Practices in Divorce on Long Island, NY

by | Dec 16, 2025 | Property Division, NY

Divorce involving a licensed professional like a doctor, lawyer, accountant, etc., 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 courts assess the value of medical, law, and accounting practices. Learn whether a professional license is considered marital property, and which business valuation methods Long Island, NY courts use. This guide will explain key factors regarding professional license in divorce in NY, how divorce affects medical practices on Long Island, and how divorce courts value lawyer businesses in New York. Our goal is to discuss the legal and financial considerations of your divorce on professional licenses so that you can protect your financial interests.

Key Takeaways from This Article

  • NY treats the value generated by a professional license or practice as marital property when earned or increased during the marriage. The valuation focuses on the practice’s economic value rather than the credential itself.
  • Distinguish personal goodwill (tied to the individual, often non-divisible) from enterprise goodwill (transferable, divisible); this distinction is central in division involving medical, legal, or accounting practices.
  • 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 and Family 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.

Understanding Professional Licenses as Marital Property on Long Island, NY

Professional licenses frequently qualify as marital property when acquired or enhanced during the marriage because they embody future earning capacity. If you’re divorcing a doctor, lawyer or accountant, expect courts to view the license as an intangible asset tied to projected income. 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 professional license divorce on Long Island, NY and divorce medical practices on Long Island disputes.

Under New York’s equitable distribution rules, property created or increased during the marriage can be considered marital property, so if you provided financial support, household labor, or career sacrifices that helped your spouse obtain a professional license, that contribution can 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 standard, so you should expect forensic accountants and business valuation experts in business valuation in NY divorce cases.

New York Specifics and Implications in Professional Divorce on Long Island

The case of O’Brien v. O’Brien (66 N.Y.2d 576, 1985) established treating a license obtained with marital support as marital property, enabling a distributive award instead of splitting the license. On Long Island, judges will apply Domestic Relations Law §236‑B factors, examine projected post-license earnings, and assess non-marital contributions when setting any monetary award.

Valuation of the license typically projects remaining career earnings (commonly 20-30 years), subtracts expenses and taxes, then discounts the income stream to present a value using rates often between 4%-8%. For example, an expert might project $3 million in net future earnings and discount it to roughly $900,000 at 6%; the court then determines what portion reflects marital effort. If you dispute the numbers, prepare to retain your own forensic accountant and vocational expert to challenge inputs and assumptions.

Valuation Methods for Professional Practices in Long Island Divorce

Three principal approaches are used to determine the value of a professional license:

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

In Long Island, NY courts, income approaches usually carry the most weight. Typical capitalization implies multiples of roughly 3-6x for stable practices and DCF discount rates often run 10-20%. Your expert should tie forecasts to historical collections, payer mix, and partner compensation to support values in professional licenses in NY divorce proceedings.

Assessing Medical Practices in Long Island Divorce

When a medical practice is assessed, experts need to quantify physician goodwill, billings, staffing, and payer mix. In this case, the specialty matters. Primary care often trades at 3-5x Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA) while surgical or specialist groups can command 5-8x. For example, a Long Island cardiology or ophthalmology group may sell near 6x EBITDA based on referrals and ancillary revenue. You must factor in Medicare exposure, non‑competes, and state licensure limits when valuing a medical practice in a Long Island divorce.

For law and accounting firms valuation experts should focus on owner compensation, client origination credits, and transferability of relationships. Solo practitioners often have mostly personal goodwill which reduces its marital value. Firm interests are commonly appraised using multiples of adjusted net income (roughly 0.8-2.0x) or revenue multiples for accounting practices. Long Island, NY courts scrutinize enterprise vs personal goodwill in lawyer business valuations in divorce cases.

Personal goodwill (clients tied to the licensee) must be distinguished from enterprise goodwill (firm reputation). Valuators generally apply discounts for each. A Discount for Lack of Control (DLOC) is typically 10-30% and Discount for Lack of Marketability (DLOM) is often 5-25%. These are then adjusted for practice size, billing rates, and buy‑sell restrictions. In practice, a solo attorney’s book may be almost entirely personal goodwill, while a partner’s share will be reduced by lack‑of‑control and marketability discounts when settling a lawyer business valuation in a Long Island, NY divorce dispute.

Business Structures and Divorce Implications in Nassau and Suffolk

When your practice is organized as a sole proprietorship, PLLC, PC or general partnership, the entity form shapes what the court treats as marital property and how your ownership is valued. For example, a Nassau or Suffolk county court will treat goodwill differently if it’s personal (tied to your license) versus enterprise goodwill (saleable with the business). This determination will affect financial outcomes in NY professional license divorce disputes and settlement leverage in medical practice divorce cases on Long Island.

How Ownership and Partnership Dynamics Affect Professional License Valuations in Long Island, NY Divorce Cases

Shared ownership, partnership agreements, buy-sell clauses and voting control all directly affect allocation and valuation. For example, a 40% ownership stake with no control often values lower than a controlling 60% stake. Courts on Long Island will examine distributions, capital accounts and precedent in business valuations in NY divorce matters to apportion marital interest based on economic realities, not just title.

Buyouts and Continuation of Practice after Divorce on Long Island

Buyouts can be structured as lump-sum, installment or a promissory note with security, commonly amortized over 3-7 years at market rates (often 4-6%), and you should account for tax consequences, ongoing practice cash flow needs and potential non-compete restrictions when negotiating settlement terms in professional license divorce splits on Long Island, NY.

For example, if your practice is valued at $1,000,000 and your 50% share equals $500,000, a five-year buyout at 5% interest amortized yields roughly $115,500 annually. Valuation methods used on Long Island, NY include capitalization of earnings, discounted cash flow and market multiples (commonly 3-5x of discretionary earnings), so you should insist on expert appraisal to support your position in professional license divorce valuation negotiations on Long Island.

How Non-Compete Clauses Affect Value Divorce Situations on Long Island

Non-compete clauses frequently alter how a professional license is valued in divorce. If your agreement bars opening a practice within 25 miles for two years, appraisers will treat that restriction as diminishing goodwill or as a separate intangible asset, often reducing the appraised valuation by 10-30%. Courts in professional license divorce cases will weigh enforceability, impact on patient or client flow, and whether the clause was negotiated during the marriage.

Ethical Considerations

When you face a non-compete clauses in a divorce involving a professional license on Long Island, NY, ethics rules for lawyers and physicians can limit how it’s enforced. For attorneys, restrictive covenants must not obstruct client choice or confidentiality, and for doctors, barriers that force abrupt patient abandonment trigger licensing board scrutiny. As a result, Nassau and Suffolk courts and regulators may reject or narrow clauses, which directly affects how your marital estate is divided and how negotiators structure buyouts or offsets.

Impact on Future Earnings

A non-compete can materially reduce your projected future earnings used in valuation. Analysts commonly lower projected annual revenue for the restriction period. Valuation experts employ income-capitalization or Discounted Cash Flow (DCF) models and adjust for enforceability risk and marketability. You’ll see higher discount rates (often 200-500 basis points more) or a marketability discount of 10-40% applied when a non-compete is present. In practice, a Long Island physician whose non-compete prevented new referrals might lose a six-figure portion of the enterprise value, so engaging an appraiser experienced in business valuation in NY divorce is vital to quantify the impact accurately.

Protecting Your Professional Interests During Your Divorce on Long Island

As you move through your divorce settlement talks, assemble 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. Engage a forensic accountant early. Expect professional valuations to cost $5,000-$25,000. Insist on separating personal earning capacity from transferable practice value to limit exposure to an inflated settlement based solely on future income.

Safeguarding Licenses and Practices When Going Through a Divorce on Long Island, NY

Because a license itself is often treated as personal and nontransferable, protect your practice by preserving client continuity, complying with state licensure rules, and preventing involuntary transfers of goodwill or patient charts. In professional license divorce cases in New York, you can seek injunctive relief to stop asset stripping and insist on valuation methods that distinguish personal goodwill from enterprise goodwill.

For more detail, retain a valuator skilled in the income and market approaches, document metrics like annual collections, EBITDA, and client retention rates, and quantify goodwill (often 20-50% of enterprise value) in disputes. Prioritize forensic tracing of marital versus separate contributions, pursue negotiated buyouts using multipliers (commonly 1.5-4x EBITDA in small practices), and use targeted discovery to expose artificially depressed or inflated earnings figures.

Frequently Asked Questions About Professional Practice Values in Long Island Divorce

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

A: New York is an equitable distribution state, and case law (e.g., O’Brien v. O’Brien) has allowed courts to treat the economic value associated with a professional license or degree as part of the marital estate. The license itself cannot be sold, but the enhanced earning capacity or goodwill generated during the marriage can be characterized as marital property subject to division. How a court treats that value depends on factors like when the license and income were earned and each spouse’s contributions.

Q: How do Nassau and Suffolk courts value a professional practice or the economic value of a license?

A: Nassau and Suffolk courts rely on business valuation experts who use standard approaches: income (capitalization or discounted cash flow), market (comparables), and asset-based methods. For professionals, the income approach, which capitalizes past and projected earnings, is commonly used. Experts will adjust for practice expenses, owner compensation, tax effects, and sometimes separate personal goodwill from practice goodwill. In complex cases involving a professional license valuation in a Long Island, NY divorce, a certified appraiser or forensic CPA is typically retained.

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

A: Enterprise goodwill is value tied to the business entity (referrals, brand, office location) and is generally divisible as marital property if built during the marriage. Personal goodwill is tied to the individual practitioner’s reputation and relationships. Some courts view it as non-transferable and therefore less divisible, though Long Island courts may still consider it in equitable distribution. Distinguishing the two effects whether the remaining spouse can claim compensation for lost future earnings tied specifically to the professional’s personal practice.

Q: When is the value of a professional practice or license determined in a divorce?

A: The valuation date of a professional license is case-specific, but is commonly the date of commencement of the action or the trial date. Nassau and Suffolk courts consider when the parties separated, changes in the practice’s earnings, and ongoing operations. Parties often seek retrospective and current valuations to capture earnings and growth during the marriage and to resolve disputes over when marital contributions ceased.

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

A: Compensation options include lump-sum payments, installment or structured payments, an offset using other marital assets, awarding interests in the business if feasible, or periodic spousal support reflecting the license’s value. Where direct transfer is impossible due to licensing or partnership rules, Nassau and Suffolk courts often craft monetary remedies or liens on future income. Buyout terms must account for tax consequences and enforcement mechanisms.

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

A: 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.

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

A: 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.”
