An irrevocable trust cannot be modified, amended, or terminated without the permission of the grantor's beneficiary or beneficiaries.

What does irrevocable will mean?

To give you a simple irrevocable definition, once the terms of the trust agreement have been written, they cannot be amended for any reason in the future (except by court order). Property held within the trust will be used for the sole benefit of the named beneficiaries.

What is the difference between a irrevocable and revocable trust?

A revocable trust and living trust are separate terms that describe the same thing: a trust in which the terms can be changed at any time. An irrevocable trust describes a trust that cannot be modified after it is created without the consent of the beneficiaries.
