What is a "creator" in New York estate law?

Definition of CREATOR: (noun) / a person who makes a disposition of property

New York Estates Powers & Trusts Law § 1-2.2 provides this general definition. However, the usage varies depending on context. A “disposition of property” means a direction of where the property will pass or to whom it will pass as in “the creator disposed of his house by leaving it to his daughter through his trust.”

The term “creator” is typically used in the context of a trust, whereas the term “testator” is typically used in the context of a will. “In her will, the testator left all her jewelry to her son.” The creator “creates” the document that disposes of the property.

Synonyms include trustor and grantor.
