FDIC insurance provides coverage to trusts, but the rules differ depending whether the trust is revocable or irrevocable. A revocable trust must meet three criteria to be insured. It must use specific language to make clear it is a trust, such as living trust or family trust. Trust beneficiaries must actually have a legal interest in the trust at the time the trust fails. And the trust beneficiaries must either be living individuals or a charity or nonprofit organization. An irrevocable trust must meet four criteria. It must be valid under state law, the bank deposit records must disclose that a trust relationship exists, the trust's beneficiaries and their legal interest in the trust must be identifiable, and the beneficiary's interest in the trust must be non-contingent.
