Preserving the legacy: trusts and inheritances in New York divorce

On Behalf of | Jan 26, 2026 | high-asset divorce

In most cases, a divorce is a personal transition that can impact years of financial planning. But when this involves large inheritances or complex trust structures, matters can complicate quickly. In these cases, the main goal is to prevent separate property from being reclassified as marital property.

When commingling and transmutation enter the picture

Under New York law, property acquired by gift or inheritance is generally classified as separate, but this can be easily challenged when commingling occurs. This could happen, for example, when inherited funds are deposited into a joint account or used to purchase marital assets, like a family home. Once the separate identity of the money is lost, New York courts may treat the entire asset as marital.

A similar concept is transmutation, which happens through actions that change the character of the property. If a person with a large inheritance uses it to renovate a joint property or a spouse contributes actively to the management of a family business held in trust, the appreciation of that asset may be subject to distribution.

Handling complex trust structures

Trusts often divide between revocable and irrevocable, and this distinction is crucial in court.

  • Irrevocable trusts: These generally offer stronger protection, as the assets are no longer considered part of the individual’s estate. However, if trust funds and income are used to support a high-standard marital lifestyle, a spouse may argue for higher alimony or other non-trust assets.
  • Revocable trusts: Because the grantor retains control, these assets are often more vulnerable to being categorized as marital property if not structured with precise legal foresight.

In high-stakes divorces, strategies like forensic tracing are often necessary. This concept includes auditing every transaction made to prove that an asset’s separate character remained intact throughout the marriage. A lawyer can offer this solution or other options if trusts and inheritances are involved in the divorce.
