The Solo Attorney's Succession Plan: Protecting Your Clients, Files, and Trust Account If You Die or Become Disabled

Picture tomorrow morning. You don't show up to the office. Not late — gone. A car wreck, a stroke, a heart attack at 58. The phone rings and nobody answers it the way you would. So ask yourself, plainly: who tells your clients? Who covers the response due Friday, the closing scheduled for Tuesday, the limitations deadline that doesn't care whether you're in a hospital bed? Who returns the files clients are legally entitled to, and who reconciles the money sitting in your trust account down to the penny?

If you're like most solo and small-firm lawyers, you have never written that plan down. The odds you'll need one are climbing. Roughly 40% of Texas attorneys are over 55, and about one in five are past 65 — and the State Bar already fields cases of lawyers who die or vanish with no one left to protect their clients. The State Bar of Texas puts it bluntly: an unplanned exit leaves “a legacy of difficulty for clients, colleagues, and the lawyer's family.”

The difficulty is concrete. Clients stranded mid-matter. Deadlines blown into malpractice claims and grievances filed against an estate that can't defend itself. And the heaviest piece — a non-lawyer spouse or executor handed a law practice they have no authority, training, or standing to wind down. A succession plan isn't an estate-planning afterthought you'll get to eventually. It's a professional obligation. This guide walks through building one.

What the Rules Actually Require (and What They Don't)

Here's the thing nobody tells you in a CLE: there is no Texas disciplinary rule that says, in so many words, “write a succession plan.” Search the Texas Disciplinary Rules of Professional Conduct and you won't find one. What you'll find instead is a set of duties you already owe every client — duties that quietly become impossible to satisfy the moment you're gone. A succession plan isn't a separate obligation bolted on top. It's how you keep faith with the rules that don't pause for your funeral.

Start with competence and diligence. Rule 1.01 forbids neglecting a legal matter entrusted to you. A solo who dies with no one designated isn't neglecting a matter through carelessness — but the matter gets neglected all the same, and the rule doesn't grade on intent. Rule 1.03 then requires you to keep clients reasonably informed and respond to their requests. A lawyer in a coma cannot return a phone call. The duty survives; your ability to honor it does not, unless someone is standing by who can.

The money is where it gets sharp. Rule 1.14 requires you to segregate client trust property, give prompt notice when you receive it, deliver it promptly when due, and account for it fully on request. None of that pauses at death. Yet trust-account access is not automatic — a spouse or executor has no standing to touch an IOLTA account, and in practice a bank generally won't release those funds on a death certificate alone. The plan has to arrange that access in advance, or the accounting Rule 1.14 demands simply never happens. And when representation ends — including by your incapacity — Rule 1.15(d) requires reasonable notice to clients, time to find new counsel, surrender of their papers and property, and a refund of any unearned fees. That's a checklist someone has to actually run.

The ABA, for its part, says the quiet part out loud. Comment 5 to Model Rule 1.3 states that the duty of diligence may require a sole practitioner to prepare a plan designating another competent lawyer to review files and take protective steps on the lawyer's death or disability. Texas hasn't adopted that comment, but the logic carries: the underlying duties are the same on both sides of the Red River.

So what happens if you do nothing? The vacuum gets filled for you. Under the Texas Rules of Disciplinary Procedure, a court can assume jurisdiction over your practice and appoint a custodian attorney — a stranger sorting your files and clients on a timeline you don't control. It is the slow, involuntary, family-burdening default. The better path is the obvious one: pick your own person, on your own terms, before you need them.

The Designated Successor: Your Most Important Hire

That person has a name in Texas: a custodian attorney. And the first thing to understand about the role is what it isn't. A custodian steps in to protect your clients and wind your practice down in an orderly way — returning files, calendaring and meeting looming deadlines, and accounting for the money in your trust account. They are not buying your book of business, and they do not inherit it. Selling or merging your practice is a real transaction you may well want to set up too, but that's an acquisition, negotiated on its own terms. The contingency role is about protection, not ownership, and conflating the two is how succession plans quietly fall apart.

Texas gives you a voluntary way to name that person before anyone needs them. Under the disciplinary procedure rules, you may designate one or more custodian attorneys in advance through the State Bar's portal (Tex. R. Disciplinary P. 13.04) — a far better outcome than the court-appointed default, where a judge picks a stranger to sort through your files. You choose; you set the terms; you tell your custodian what you expect.

Reduce that arrangement to a written agreement. A handshake over coffee is not a plan. At minimum, the agreement should specify:

• Scope — what the custodian is authorized to do, and what they are not.
• Triggering events — death, disability, disappearance, or suspension, defined clearly enough that someone can act on them without guessing.
• Authority — access to files, the office, and your trust account is arranged through this agreement; it is not automatic.
• Compensation — how your custodian is paid for the work, settled in advance rather than improvised later.
• Confidentiality and conflicts safeguards — the guardrails below.

Those last two words carry real weight. Your custodian will be reading privileged client files. The confidentiality rule permits that disclosure only because it allows revealing confidential information when a lawyer is authorized to carry out the representation, and to others in the firm (Tex. Disciplinary R. Prof'l Conduct 1.05(b)-(c)) — so the engagement has to be structured to fit those exceptions, not assumed to override the duty. Your custodian also has to screen your client list against their own to catch conflicts before they touch a file.

Client Files, Trust Accounts, and the IOLTA Problem

Once you've named a successor, the next question is what, exactly, they take custody of. Two assets are far harder to hand off than the rest: the files and the money. Both come with duties that outlive you, and the money comes with a trap most solos never see coming.

The Files

Texas sets no fixed retention period. There is no magic seven-year rule that lets your successor shred everything and move on. The standard is reasonableness: under Ethics Opinion 627, a file should be kept as long as there is a reasonable likelihood that destroying it would harm a former client's important interests. That's a judgment call, and you don't want a stranger making it cold. Build a file inventory and a return-or-retain protocol your successor can actually follow.

One category is not a judgment call. Original documents of unique value — wills, deeds, signed contracts, securities — must be returned to the client in their original form and must never be destroyed without the client's permission. Flag those in the inventory so they go home, not into a shredder.

The Trust Account

This is the one that catches people. Your client trust funds sit in an IOLTA account, and when the sole authorized signatory dies or becomes incapacitated, that account effectively freezes. Meanwhile, Rule 1.14 still demands prompt notice to clients and prompt delivery and accounting of their funds — duties that do not pause for your funeral.

Here is the part nobody plans for: there is no automatic successor access. Your spouse, your executor, even the custodian you carefully chose has no standing to move a dime in that account unless you arranged access in advance — by adding a signatory, granting a durable power of attorney, or building in a path to a court order. And you can't just drain or abandon the account to make the problem go away. IOLTA funds are regulated; the interest funds legal aid through the Texas Access to Justice Foundation, and unclaimed balances fall under Texas unclaimed-property law. The money has to be accounted for and delivered, not buried.

Building the Plan: Documents, Authority, and Access

Before you assemble the kit, understand what your entity actually does when you die: it tries to disappear. If you practice through a single-member PLLC, Texas law treats the death of the sole member as an event requiring winding up—and it puts the entity on a one-year clock to do exactly that, unless within that year your legal representative or successor becomes a member or designates someone who will (Tex. Bus. Orgs. Code § 11.056). Absent advance arrangement, your firm is built to dissolve, not to be inherited.

And your family cannot simply step in and run it. A law PLLC may be owned only by an authorized—meaning licensed—person, so a non-lawyer spouse or executor who succeeds to your interest must promptly relinquish it and cannot keep the practice going (Tex. Bus. Orgs. Code ch. 301). What that heir actually receives is narrow: only the economic rights of an assignee, not management or membership (§ 101.1115). They can collect what's owed; they cannot make a single decision about a client matter.

The translation matters more than the statutes. The corporate shell is designed to wind down, which is precisely why the human you name—your custodian—carries the plan. The documents below exist to give that person authority the entity itself will not.

• Authority instruments. A limited power of attorney or written authorization, drawn under Texas powers-of-attorney, so your successor can deal with the bank, the courts, and your clients without litigating standing first.
• A live matter inventory. An up-to-date list of active matters with their deadlines—the thing your custodian opens on day one (State Bar of Texas, Succession Planning Toolkit).
• Access credentials. Logins for practice-management software, email, and the trust account, current and stored where the custodian can reach them (same source).
• Tail coverage. An extended-reporting-period endorsement so claims surfacing after wind-down stay covered—confirm the terms with your malpractice carrier, such as TLIE, since the specifics are policy, not statute.

Build the instruments now, while you can sign them.

Death vs. Disability: Two Different Triggers

An instrument is only as useful as the event that switches it on. With death, that switch is obvious: there's a certificate, and under the cessation-of-practice rules a probate court can assume jurisdiction over your practice once you've died. The catch is timing. A probate process takes weeks to spin up, and your clients' deadlines don't pause to wait for it — which is why your successor's authority has to attach the moment it's needed, not whenever the court gets around to you.

Disability is the harder case, and the disciplinary framework reaches it — along with disappearance — not just death. There's no certificate here. The ambiguity is real: who decides you're impaired, and is the impairment temporary or permanent? The rules don't answer that for you, so your plan has to. Pick a triggering standard and write it down — a treating physician's certification, say, or a named person's determination that you can no longer practice. Then distinguish the two flavors of impairment. A temporary one means you'll be back; you need interim coverage, not a wind-down. A permanent one looks more like death, procedurally — someone has to close the practice for good.

The instrument that makes disability coverage actually work is a durable power of attorney. Unlike a death-triggered probate process, a durable POA under the Texas Estates Code survives your incapacity without waiting for any court to declare anything — your designated successor can act during the disability. That's the whole point of “durable.” Build the trigger into the document, not just the authority.

Actionable Next Steps

You've read the whole argument; now turn it into a list you can work through this week. None of these steps requires a litigator's budget or a second associate. They require an afternoon and a signature while you still have both.

1. Name a custodian and sign a written agreement. Pick a trusted attorney, put the arrangement in writing, and formalize it through the State Bar's voluntary custodian designation under Texas Rule of Disciplinary Procedure 13.04.
2. Solve the trust-account signatory problem now. Add a signatory, grant a power of attorney over the account, or set up a court-order path in advance. Rule 1.14 still demands a prompt accounting and delivery of client funds, but it gives your successor no automatic access — so build that access yourself.
3. Sign the authority instruments. A limited power of attorney for the practice, plus a durable power of attorney with a clear disability trigger, so your custodian can act when you can't.
4. Build a live inventory of active matters and deadlines — and keep it current, not frozen at the date you first wrote it.
5. Store access credentials for practice management, email, and the trust account somewhere your custodian can actually reach.
6. Line up malpractice tail coverage with your carrier before you need it.
7. Tell your spouse, executor, or office where the plan lives. A perfect plan nobody can find is no plan.
8. Review it annually.

You don't have to draft any of this from scratch. The State Bar of Texas Succession Planning Toolkit walks Texas solos through designation, file management, custodianship, and transition. For a national reference, the ABA's Planning Ahead: A Guide to Protecting Your Clients' Interests handbook covers the same ground in depth.

The hardest part is starting. And the plan only protects anyone if you sign it while you still can.
