Who Can Request Removal
The right to petition for removal is broad. The person who created the trust (the settlor), any cotrustee, or any beneficiary can bring the request to court. The court can also start the removal process on its own if the situation calls for it.
The court may remove a trustee if: 1. The trustee has committed a material breach of trust. 2. Lack of cooperation among cotrustees substantially impairs the administration of the trust. 3. Because of unfitness, unwillingness or persistent failure of the trustee to administer the trust for the benefit of the beneficiaries, the court determines that removal of the trustee best serves the interests of the beneficiaries.
A.R.S. § 14-10706(B)(1)-(3)The standard is practical, not punitive. The court looks at whether keeping the trustee in place serves the beneficiaries' interests. A single mistake may not be enough. But a pattern of neglect, a serious breach, or an inability to work with cotrustees can justify removal.
What Removal Looks Like in Practice
Removal does not happen overnight. The court may issue temporary orders to protect trust property while the petition is pending. It can also appoint a temporary fiduciary to manage assets during the transition. These steps prevent harm to beneficiaries while the court considers the full picture.
A trustee who faces a removal petition is allowed to defend against it. However, the court controls how much of the trust's money can be used for that defense. This prevents a trustee from draining trust assets to fight their own removal.
Special Protection for Settlor-Beneficiaries
There is an additional safeguard for people who created a trust and are also beneficiaries of it. If the settlor-beneficiary petitions the court, the court is required to substitute the trustee and appoint a successor when doing so is in the beneficiary's best interest.
On petition of a beneficiary who is also a settlor of a trust, including a beneficiary for whom a guardian or conservator has been appointed, the court shall substitute a trustee and appoint a successor if the substitution is in the best interest of the beneficiary.
A.R.S. § 14-10706(D)This provision protects people who set up revocable living trusts and later need a different trustee, especially if incapacity becomes a factor. The court can also appoint someone nominated by the beneficiary, as long as the beneficiary has sufficient mental capacity to make that choice.
