A Third-Party Funded Supplemental Needs Trust permits a family to plan and financially provide for an individual with disabilities without affecting the individual’s eligibility for government benefits. These trusts are created and funded by a third party (the Settlor). They are often created and funded by relatives and can exist as part of their will (a Testamentary Trust), or they can be created, funded, and funds can be disbursed while the Settlor is still alive (Inter-Vivos Trust).
