In which scenario would a trust be considered irrevocable?

A trust is considered irrevocable when it cannot be altered or revoked after its creation. In this case, a trust becomes irrevocable upon the death of the grantor. Once the grantor passes away, the assets and terms of the trust are set, and the intentions outlined in the trust document must be followed. This characteristic is key in estate planning, as it allows for the orderly distribution of assets according to the grantor's wishes without further modification.

The other scenarios describe situations that do not result in an irrevocable trust. For example, a trust that can be revoked at any time while the grantor is alive indicates a revocable trust, allowing the grantor to make changes or dissolve it. Additionally, the establishment of a trust through a will refers to a testamentary trust, which takes effect upon the death of the grantor but can still be adjusted prior to that point. Beneficiary entitlement to assets does not inherently define the trust as irrevocable, as some irrevocable trusts may still allow for the distribution of benefits to beneficiaries while remaining unalterable in structure.
