Estate Planning Basics Everyone Skips: Trusts, Powers of Attorney, and Successor Trustees

Start with the documents, because each one does a specific job and none of them substitutes for another. A revocable living trust holds title to your assets during life, lets you stay in full control as trustee, and names a successor trustee to take over at incapacity or death without court involvement. A pour-over will catches anything left outside the trust and directs it into the trust, though those assets may still pass through probate first. A durable financial power of attorney names an agent to handle assets that are not in the trust: IRAs, tax returns, Social Security, insurance claims. A health care power of attorney names someone to make medical decisions, a living will states your wishes about end-of-life treatment, and a HIPAA authorization lets named people receive medical information. That last one is small but matters, because many trusts define incapacity using physician letters, and your successor needs access to that information to step in.

Beneficiary designations and beneficiary deeds sit outside all of this and override it. An IRA, 401(k), annuity, or life insurance policy passes to whoever is named on the account form, regardless of what the will or trust says. In Arizona, a beneficiary deed under A.R.S. 33-405 lets real estate pass directly to a named beneficiary at death without probate, but it must be recorded with the county recorder before death to be effective. Arizona is also a community property state, which affects how assets are titled, how they are divided, and how basis steps up at the first spouse's death. Getting titling and designations right is often worth more than anything in the trust document itself.

The incapacity problem is the one most people ignore. If you have a stroke, develop dementia, or are seriously injured and have no durable financial power of attorney, no one has automatic legal authority over assets in your individual name. Your spouse can manage joint accounts, but not your IRA, not your separate accounts, and not decisions that require your signature. The fallback in Arizona is a conservatorship (for finances) or guardianship (for personal and medical decisions) through the superior court: a public proceeding with filings, court oversight, annual accountings, legal fees, and delays measured in weeks or months. A revocable trust handles incapacity for trust assets, and a durable power of attorney handles everything else. Arizona requires a financial power of attorney to be signed, witnessed, and notarized to be valid, so an old form downloaded online may not work when it is needed.

Choosing a successor trustee deserves more thought than it usually gets. The job involves inventorying assets, paying final bills and taxes, filing a final Form 1040 and possibly trust income tax returns, communicating with beneficiaries, and distributing assets according to the document, sometimes over years. The right person is organized, trustworthy, reasonably comfortable with money, and able to handle family friction. Geography matters less than it used to, but a local trustee is still easier for real estate and paperwork. Co-trustees can balance skills but can also deadlock. A professional or corporate trustee brings neutrality and continuity, typically for an annual fee often in the range of about 1% of trust assets with minimums, and can be named as a backup or as co-trustee alongside a family member.

Funding the trust is where most plans fail. A trust only controls assets titled in its name. That means retitling brokerage and bank accounts to the trust, recording a deed transferring your home to the trust (or using a beneficiary deed), and assigning personal property. Retirement accounts are the exception: an IRA cannot be owned by a trust during your life, so it is coordinated through beneficiary designations instead, and naming a trust as IRA beneficiary has its own tax rules under the SECURE Act 10-year framework. Every new account you open after signing the trust needs to be titled correctly. An estate attorney drafts the documents; the funding follow-through often falls to the family and their financial advisor, and it is where coordination pays off.

Digital assets and a letter of instruction round out the plan. Arizona has adopted the uniform law on fiduciary access to digital assets, but your successor still needs to know what exists: online financial accounts, email, password managers, photo libraries, cryptocurrency, and any accounts with two-factor authentication tied to your phone. A letter of instruction is not a legal document. It is a plain-language guide that lists your accounts, advisors, insurance policies, recurring bills, where original documents are stored, and your wishes on practical matters. It is often the single most useful thing a successor trustee receives.

If your documents were signed more than five years ago, or before a move to Arizona, schedule a review. Documents drafted in another state are generally still valid, but powers of attorney and health care documents in particular should be checked against Arizona requirements so a bank or hospital does not reject them when it matters. Your estate attorney drafts and updates the documents; a planner's role is to coordinate titling, beneficiary designations, and the financial side so the plan actually works.

Pull every beneficiary designation form and read it. Confirm primary and contingent beneficiaries on each IRA, 401(k), annuity, life insurance policy, and transfer-on-death account. Many estate plan failures are not drafting errors; they are a 15-year-old designation naming an ex-spouse or a deceased parent.

Walk through the incapacity scenario with your spouse and your named agents. Who pays the bills if you cannot? Does that person know where the accounts are, and do they have the documents? Is the successor trustee willing to serve? A 30-minute conversation now prevents months of confusion later.

Build a folder for your successor: copies of the trust, will, powers of attorney, health care documents, a current asset list with account numbers and titling, contact information for your attorney, CPA, and advisor, and your letter of instruction. Tell your successor where it is. Update the asset list at least once a year.

For most readers in the $1.5 million to $5 million range, estate tax is not the issue at a $15 million exemption. The priorities are avoiding probate, avoiding a conservatorship, minimizing income tax for heirs (IRA beneficiary planning and the community property step-up), and reducing the administrative burden on the people you leave in charge.

• Signing a revocable living trust and never retitling accounts or the home into it, leaving the trust empty and the estate headed to probate anyway.
• Having no durable financial power of attorney, so a spouse or child must petition an Arizona court for a conservatorship to manage assets in your individual name.
• Naming the oldest child as successor trustee by default rather than the person with the skills, availability, and temperament to do the job.
• Leaving outdated beneficiary designations on IRAs and life insurance, which override the will and trust entirely.
• Retitling an IRA into a trust, which is treated as a full distribution and triggers income tax on the entire balance.
• Skipping the HIPAA authorization, which can prevent the successor trustee from getting the medical information needed to certify incapacity.
• Never reviewing the plan after a death, divorce, remarriage, move from another state, or a large change in assets.
