What type of trust allows the creator to retain the ability to modify or terminate it?

A revocable trust allows the creator, often referred to as the grantor or settlor, to maintain control over the trust during their lifetime. This means that the grantor can modify the terms of the trust, add or remove assets, or even terminate the trust entirely if they wish. This flexibility makes revocable trusts particularly appealing for individuals who may want to make adjustments as their circumstances change.

Unlike irrevocable trusts, where the creator forfeits control once the trust is established, a revocable trust continues to be under the grantor's direction. This enables effective estate planning since the trust can be altered to meet future goals or to respond to changing life situations, such as changes in family dynamics, financial circumstances, or tax laws.

The other options do not provide this level of control. For instance, an irrevocable trust cannot be changed once established, which locks in the terms and often removes assets from the grantor's estate for tax purposes. Secure and fixed trusts refer to other types of arrangements that do not inherently include the grantor's ability to modify the trust after its creation.
