A high-net-worth divorce in New York can involve financial and legal issues that extend far beyond those encountered in a more conventional matrimonial case. When spouses own businesses, professional practices, substantial real estate, investment portfolios, retirement accounts, restricted stock units, executive compensation, trusts, valuable personal property or other significant assets, identifying and valuing the marital estate can become one of the most important aspects of the divorce. New York follows the principle of equitable distribution, which does not necessarily mean that every marital asset is divided equally. Instead, courts consider numerous statutory factors in determining an equitable distribution of marital property. Before assets can be distributed, however, they generally must be identified, classified as marital or separate property when appropriate, valued, and analyzed. In a high-asset divorce, that process may require careful financial discovery as well as assistance from forensic accountants, business valuation professionals, real-estate appraisers and other experts.
Marital Property and Separate Property in New York
One of the first issues in a New York high-net-worth divorce is determining what constitutes marital property. Generally, property acquired by either spouse during the marriage is potentially marital property regardless of whose name appears on the title, subject to important statutory exceptions. Separate property can include assets owned before marriage as well as certain inheritances, gifts from third parties and compensation for personal injuries. The classification question can become considerably more complicated when separate and marital assets have been mixed together, separate funds have been used to purchase jointly titled property, or a premarital asset has increased in value during a lengthy marriage.
For example, a spouse may have owned a business before the marriage but continued operating and developing that business throughout the marriage. The business itself may have originated as separate property, while some portion of its appreciation may become an issue in equitable distribution depending upon the circumstances and the contributions of the spouses. Similar questions can arise with investment accounts, real estate and other appreciating assets. Tracing the source and movement of funds can therefore become extremely important. Bank statements, brokerage records, tax returns, closing documents and historical business records may be necessary to establish whether an asset—or a particular portion of an asset—should be treated as marital or separate property.
Business Valuation and Professional Practices
Closely held businesses and professional practices frequently present some of the most difficult valuation questions in a high-net-worth divorce. A business may represent both a family’s principal source of income and one of the largest assets in the marital estate. Determining its value can require an examination of financial statements, tax returns, cash flow, liabilities, ownership agreements, market conditions and other financial information. Depending upon the circumstances, valuation professionals may also examine whether reported income accurately reflects the economic benefits received by the owner. The objective is not necessarily to physically divide a company between two divorcing spouses. In many cases, one spouse continues owning or operating the business while the other spouse receives an appropriate distribution through other assets or a structured financial arrangement. Reaching that result, however, requires a reliable understanding of what the business is worth and what portion, if any, is subject to equitable distribution.
Professional practices can present additional issues. Physicians, attorneys, accountants, financial professionals and other licensed professionals may have ownership interests or compensation arrangements that require specialized analysis. Partnership agreements, buy-sell provisions, deferred compensation and other restrictions can affect both valuation and the practical ability to transfer an interest.
Executive Compensation, Investments and Complex Financial Assets
Modern compensation arrangements have made some high-income divorces considerably more complicated. An executive’s compensation may consist not merely of salary and annual bonuses but also restricted stock units (RSUs), stock options, stocks, interest in business, deferred compensation, carried interests, partnership interests and other incentive compensation. Determining whether these interests are marital property—and, when appropriate, how they should be valued and distributed—can require careful examination of when the compensation was earned, why it was awarded, when it vests and what restrictions apply to it.
Investment portfolios can create similar problems. Brokerage accounts may contain securities purchased both before and during the marriage. Assets may have been transferred among different accounts over many years. Investment gains, dividends and reinvestments can make tracing particularly important when a spouse asserts a separate-property claim.
Real estate may also constitute a substantial portion of a high-net-worth marital estate. In addition to the marital residence, spouses may own vacation properties, investment properties, commercial buildings or property through limited liability companies and partnerships. Current valuations, outstanding debt, tax consequences and liquidity all can influence the ultimate financial resolution.
Financial Discovery and Hidden Assets
Accurate financial disclosure is essential in any divorce, but the stakes can be particularly high when millions of dollars or complicated ownership structures are involved. A high-net-worth divorce attorney in New York may need to examine tax returns, bank accounts, brokerage statements, business records, credit-card statements, loan applications and other documents to develop an accurate picture of the marital estate.
Where financial information is incomplete or inconsistent, additional discovery may be necessary. Depositions, subpoenas and expert analysis can sometimes reveal assets, income or transactions that are not immediately apparent from a spouse’s initial financial disclosures.
Forensic accountants can be particularly useful when business and personal finances overlap or when money has moved through numerous entities or accounts. They may reconstruct cash flow, trace funds, analyze business expenditures and identify discrepancies between reported income and actual financial activity. Not every high-net-worth divorce requires forensic accounting, but when substantial financial questions exist, a careful investigation can have a significant effect on the outcome.
High Income, Maintenance and Child Support
High-income cases can also raise complicated questions concerning spousal maintenance and child support in New York. Statutory formulas play an important role, but cases involving income above statutory caps can require additional analysis. Courts may consider the parties’ circumstances and statutory factors when determining whether and to what extent income exceeding the applicable caps should affect an award.
Determining income itself can sometimes be contentious. A business owner or executive may receive compensation in forms that are less straightforward than a conventional paycheck. Bonuses, distributions, deferred compensation, investment income and business benefits may all require analysis. A lawyer handling a high-income matrimonial case should therefore understand not only the applicable support statutes but also the financial documents necessary to evaluate the parties’ actual economic circumstances.
Prenuptial and Postnuptial Agreements
A valid prenuptial or postnuptial agreement can dramatically affect a high-net-worth divorce. Such agreements may determine how certain property will be characterized or distributed, establish or waive maintenance rights, address business interests and resolve other financial issues before a divorce occurs.
When a high-asset divorce involves a marital agreement, one of the first tasks is to analyze the agreement carefully and determine its effect on the issues presently in dispute. Questions can arise concerning interpretation, enforceability and whether particular property falls within specific provisions of the agreement.
For individuals or spouses entering marriage with significant assets, businesses, family wealth or anticipated inheritances, thoughtful planning before marriage can also reduce uncertainty if the marriage eventually ends.
