The Default Rule Favors Flexibility
One of the most important features of a revocable living trust is the ability to change it. The law presumes that an existing trust can be revoked or amended unless the trust document itself says otherwise. If the word "irrevocable" does not appear in the original trust, the settlor retains full control.
Unless the terms of a trust expressly provide that the trust is irrevocable, a settlor may revoke or amend the trust subject to any limitations prescribed in the terms of the trust.
A.R.S. § 14-10602(A)Revocation can happen in several ways. The settlor can follow the method described in the trust itself. They can also use a later will or codicil that references the trust. Any signed writing that shows clear intent is enough. To avoid confusion, it is best to follow the method your trust administration plan already describes. The original trust does not need to be physically destroyed to be revoked.
When Spouses Create a Joint Trust
Joint trusts are common among married couples. This statute draws an important line between community property and separate property within the trust. Either spouse can revoke the existing trust as to their share of community property. However, amending it requires both spouses to act together. These legal requirements protect both parties.
To the extent the trust consists of community property, the trust may be revoked by either spouse acting alone as to that spouse's share of the community property but may be amended only by joint action of both spouses.
A.R.S. § 14-10602(B)(1)An agent under a power of attorney can also exercise these powers, but only if the trust terms or the power of attorney document expressly authorize it. This is a critical detail for incapacity planning. If neither document grants that authority, a court-supervised conservator or guardian may need to step in.
For any family member serving as agent or successor trustee, understanding these trust laws matters. Knowing the right steps to amend or revoke the trust prevents costly mistakes. An experienced estate planning attorney can help make sure changes are done correctly and meet all legal requirements.
Keeping your trust up to date is one of the most important things you can do. Life changes such as marriage, divorce, births, and deaths all affect how your trust should be structured. Reviewing your existing trust every few years with a qualified professional helps ensure it still reflects your wishes.
