Claflin v. Claflin, 149 Mass. 19, 20 N.E. 454 (Supreme Judicial Court of Massachusetts 1889)
Claflin v. Claflin is a foundational trusts-and-estates decision that crystallizes what is now widely known as the Claflin doctrine: even if beneficiaries are adults and consent, a court will not terminate or modify a trust when such action would contravene a material purpose of the settlor.
May a court compel early termination of a testamentary trust at the request of an adult beneficiary—who is or will be the ultimate owner—when the trust instrument clearly postpones principal distribution to a later age and such termination would defeat a material purpose of the settlor?
Under the Claflin doctrine, a trust may not be terminated or modified—despite the consent of all beneficiaries and their being of full capacity—if doing so would be contrary to a material purpose of the settlor. Material purposes commonly include spendthrift restraints, support/protection objectives, and postponement of enjoyment until a stated age. Courts of equity enforce the settlor's intent, as expressed in the instrument, so long as it is lawful and feasible, and will not order termination where the trust's purposes have not yet been accomplished or would be defeated by premature distribution.
No. The court refused to terminate the trust. The trustees were required to continue administering the trust and to distribute principal only at the times and in the manner specified by the will.
Claflin is the seminal American case anchoring the material-purpose limitation on consensual trust modification and termination. It frames modern doctrine codified in many jurisdictions (e.g., UTC § 411), which permits modification or termination with unanimous beneficiary consent only if not inconsistent with a material purpose. The case supplies the exam-ready categories of material purposes—spendthrift restraints, support trusts, and age-postponement provisions—and it offers a template for analyzing when beneficiary autonomy yields to settlor intent. It also provides a critical contrast to Saunders v. Vautier, sharpening students' understanding of comparative approaches to trust termination.
