Modern solo practice: a working resource

Why this resource exists

The market produces a lot of content for large-firm lawyers. There is comparatively little practical guidance written specifically for solos and small-firm litigators who are trying to run real practices in 2026.

This resource is a working document — observations from twenty-five years of practice, organized around the questions that come up in the day-to-day of running a solo or small litigation practice today. It covers infrastructure decisions, professional responsibility under the new AI rules, financial structure, marketing posture, and the cluster of practical decisions that determine whether a solo practice is sustainable over decades.

It is not exhaustive. It is what one practitioner has learned, written down in a way that hopefully helps the next practitioner.

Section 1 — Practice infrastructure

The most consequential set of decisions a solo or small firm makes are infrastructure decisions: what tools you use, how they work together, what you keep manual and what you automate.

The stack question. Most solos run a stack of seven to ten tools — practice management, research, AI, calendaring, billing, document storage, e-signature, communications, and so on. The cumulative cost is higher than most solos track. The cumulative complexity is higher than most solos manage well. See the stack calculator for a category-by-category audit.

The consolidation question is real: is your firm better off with seven specialized tools tied together by ad-hoc workflows, or with a smaller number of tools that handle more capabilities? Twenty-five years ago, the answer was clearly the specialized stack — the consolidated platforms didn't exist at the quality level a litigation practice needed. In 2026, the answer is less clear, and is becoming "consolidated" for an increasing number of firms.

The decision framework I would suggest: which tools save you time vs. which tools make your work better? Time-saving tools max out at the limit of your bandwidth. Quality-improving tools compound over decades. The foundational infrastructure investments are the quality-improving ones.

The deadline engine question. California and Federal civil practice deadlines are produced by a stack of rules — statewide procedural rules, local rules of the specific court, standing orders of the assigned judge. Ad-hoc deadline tracking (spreadsheets, calendar reminders, mental note) misses the local and departmental layers and produces missed deadlines.

A reliable deadline engine that knows the actual procedural rules of the actual jurisdiction and court the matter sits in is, in my view, the single most important infrastructure investment a litigator can make. The cost of a missed deadline in California civil practice — especially one involving the CCP § 2033.280 deemed-admitted rule — is high enough to justify spending substantial resources on the deadline infrastructure that prevents it. See the California and Federal deadline guide for the rule-stack details.

The document organization question. Litigation files are different from transactional files. A matter has pleadings, discovery (propounded and received, in multiple rounds), depositions (taken and defended, with exhibits), expert reports, correspondence (with client, opposing counsel, and court), motions (in various states), evidence, and trial preparation materials. A flat folder of PDFs does not match the actual structure of the work.

The document organization tool should match the litigation taxonomy. Most practice management platforms do not, because they were built for general practice. A litigation-specific platform is structurally better positioned to do this; alternatively, a disciplined manual folder structure outside the practice management platform can compensate.

The AI tooling question. As of 2026, AI tooling for litigation falls into three categories: consumer chatbots; bolt-on AI features in legacy platforms; and litigation-specific AI built around defensible architecture. The professional responsibility implications of each are different.

Consumer chatbots are appropriate for non-substantive language work and learning unfamiliar areas. They are not appropriate for citation production, court filings, or substantive legal analysis in client matters — see the bolt-on AI article and the JILL vs. chatbot article.

Bolt-on AI in legacy platforms tends to inherit the underlying platform's limitations. It is useful for the kinds of work the platform was already good at; it generally does not solve the hallucination problem.

Litigation-specific AI with defensible architecture (validation, confidence scoring, audit logging, tamper-evident chain) is the category I built Discover Docket to occupy. The case for it is that it operationalizes the professional responsibility duties at the infrastructure layer rather than depending on individual lawyer discipline. See the DDEAS framework.

Section 2 — Professional responsibility under the AI rules

Every state bar in the country has now issued some form of AI guidance, and federal courts have established sanctions law that applies regardless of state-level guidance. See the 50-state survey article.

For a solo practitioner, the duties that matter most under ABA Formal Opinion 512 and the corresponding state guidance:

Competence (Model Rule 1.1). Understand the technology you use, including its capacity to fabricate authoritative-looking output. Be able to articulate in two or three sentences how your AI tool works and where it can fail. If you can't, you are not yet competent to use it on client matters.

Confidentiality (Model Rule 1.6). Do not transmit client information to consumer AI tools without informed client consent. Either obtain consent explicitly, or use tools with contractual zero-retention and no-training terms that satisfy the confidentiality duty without consent.

Communication (Model Rule 1.4). Address AI use in engagement letters. Explicit language up front is easier than litigating client expectations after the fact.

Candor toward the tribunal (Model Rule 3.3). Verify every citation produced by AI against an authoritative source before it appears in a court filing. Mata v. Avianca and Park v. Kim establish that the verification duty cannot be delegated to the AI itself. See the Mata article and the Park v. Kim article.

Supervision (Model Rules 5.1 and 5.3). If you have any non-lawyer support — paralegals, legal assistants, even contract attorneys — you owe supervision duties under Rule 5.3 for their AI use, and Rule 5.1 if any are lawyers. This applies even to solos with one part-time assistant.

Reasonable fees (Model Rule 1.5). Bill consistent with actual time expended. Do not bill at rates that don't reflect the AI's role in compressing the work. Consider whether flat-fee or value-based pricing better reflects the work in matters where AI compresses time substantially.

Practical compliance checklist:

1. Written firm AI policy (even for solos — one page is enough)
2. Documented training for everyone in the firm who uses AI
3. Verification step structurally built into the citation-producing workflow
4. Engagement letter language addressing AI use
5. AI tool selection limited to tools with contractual confidentiality protections
6. Audit logs preserved for any AI-assisted work product
7. Billing practices reviewed for alignment with actual time

Most solos are behind on items 1, 2, and 6. Catching up is a one-day project; the exposure of staying behind grows monthly.

Section 3 — Financial structure

Solo practice is cash flow management as much as it is law. The infrastructure decisions that affect cash flow:

Billing frequency. Monthly billing produces more predictable cash flow than quarterly billing. Send invoices promptly at month-end. Solos who let billing slip three weeks routinely end up with cash flow gaps in months four and five.

Trust accounting. California's Client Trust Account Protection Program (CTAPP) requires annual reporting of trust account activity. Solos must register annually and certify compliance with the trust accounting rules under Rule 1.15 of the California Rules of Professional Conduct. Failure to register or to comply with the underlying trust accounting rules is professional misconduct.

Reserves. A solo practice should maintain operating reserves equal to three to six months of overhead, depending on the practice's matter mix. Plaintiff contingency practices need more reserves than defense-side hourly practices.

Pricing decisions. Hourly billing has structural problems in an AI-compressed environment — clients increasingly notice when AI-assisted work that previously took hours now takes minutes, and the bill doesn't change. Flat-fee or value-based pricing for AI-assisted matters aligns the firm's economics with the work actually performed.

Tax structure. Most solos operate as PCs, LLCs, or sole proprietorships. Tax structure choice affects self-employment tax exposure, retirement plan contribution limits, and disability insurance options. Consult a CPA familiar with law-firm tax issues; the right structure depends on practice income level and other factors.

Section 4 — Marketing posture

Marketing is the part of solo practice most lawyers handle worst. Three observations:

Referrals are the durable channel. Over twenty-five years, the channels that have produced the highest-quality matters for my practice have been other lawyers and former clients. Online channels are useful for visibility; they do not produce the matters that sustain a practice.

Be useful to other lawyers. The lawyers who get referrals are the lawyers who give referrals. Treat your peers as a professional network, not as competitors. Refer matters that don't fit your practice to lawyers who handle them well. The favor returns.

Specialization helps. A solo who is the obvious referral choice in a specific area of practice gets more and better matters than a solo who is "available" for a range of work. The specialization doesn't have to be narrow — civil litigation is a specialization, employment defense is a specialization. But the marketing posture should make clear what the firm does well.

Section 5 — Operations

A few practical operations observations from twenty-five years:

Use checklists. Litigation practice has dozens of recurring procedural sequences — case opening, deposition preparation, motion filing, trial preparation. Checklists reduce the cognitive load of running the practice and prevent the small-but-costly errors that come from doing each task from memory each time.

Document your processes. The senior solos I know consistently regret not writing down how they did things. The institutional knowledge of a thirty-year solo practice is enormous and walks out the door at retirement. A wiki, a structured workspace, or a set of templates inside your practice management platform preserves what you learn.

Cross-train your staff. Even one-person practices typically have a part-time legal assistant or virtual paralegal. The risk of a solo plus one assistant is that the assistant's departure or illness paralyzes the practice. Cross-training, even minimal, mitigates this.

Plan your succession. Solos rarely plan succession until late in their careers, by which point planning is harder. Even a fifteen-year solo should have an informal arrangement with another lawyer to cover urgent matters in the event of unavailability, and an understanding of how the practice would wind down if necessary.

Section 6 — The work itself

Infrastructure, professional responsibility, finance, and operations are the framework. The work itself is what the framework exists to support.

The work, in my experience, requires three things that no infrastructure can substitute for: attention to the client's actual situation, judgment about what the law can and cannot do for them, and the willingness to do the hard parts of the case rather than the easy parts. The lawyer who does these three consistently builds a practice that lasts. The lawyer who lets the infrastructure substitute for them does not.

The right relationship between the lawyer and the infrastructure is the same as the relationship between a craftsperson and her tools. The tools matter. They are not the work.
