How to Start a Law Firm: A Step-by-Step Checklist

Starting a law firm means passing your bar's admission and good-standing requirements, choosing a business structure, securing malpractice insurance, setting up a compliant trust account, and deciding how you'll manage cases, bill clients, and get found by the people searching for a lawyer like you — usually in that order, over the course of a few months before you take your first client. None of these steps are optional, and skipping ahead to marketing before the compliance and operational basics are in place is the most common way new firms create problems for themselves later. This checklist walks through the sequence in roughly the order most solo and small-firm lawyers tackle it. 1. Choose your practice structure Most solo and small-firm lawyers organize as a professional limited liability company (PLLC) or professional corporation (PC) rather than a standard LLC, since many states require licensed professionals to use an entity type specific to regulated professions . The entity choice affects liability protection, how you're taxed, and in some states whether non-lawyers can hold an ownership stake at all. A few states still permit sole proprietorships for solo practitioners, but most new firms incorporate from the start for liability and tax reasons. This is a decision worth making with an accountant or business attorney familiar with your state's rules, not just a form you fill out online. 2. Confirm bar admission and good standing You need to be admitted and in good standing with the state bar where you intend to practice, and if you plan to open an office in a second state, you'll generally need separate admission there too — reciprocity and "admission on motion" rules vary significantly by state pair . If you're leaving a firm to go solo, check your state bar's rules on client notification and file transfer before you give notice; several states require specific language in the departure letter to clients whose matters you're taking with you, including how pending matters and client files are handled during the transition. This is also the point to register for your state's mandatory CLE (continuing legal education) tracking if you haven't already, and to confirm your registered address with the bar is current — notices about your license, dues, and any complaint filed against you typically go to whatever address is on file, and a missed notice because of a stale address is not a defense most bars will accept. 3. Get malpractice (E&O) insurance before you take a single client Legal malpractice insurance, sometimes called professional liability or errors-and-omissions (E&O) coverage, isn't legally required in every state, but a small number of states do mandate it or require you to disclose to clients that you're uninsured if you choose to go without it . Even where it's optional, taking on a single client without coverage is a significant personal risk for a new solo practice — one malpractice claim, regardless of whether it has merit, can be more expensive to defend than a year of premiums. Get quotes before you finalize your entity structure, since practice area, claims history, and firm size all affect pricing, and a broker who works with law firms specifically will know which carriers are comfortable insuring a brand-new solo practice. 4. Set up your trust (IOLTA) account and business banking If you'll hold client funds — retainers, settlement proceeds, costs advanced on a client's behalf — you need a separate trust account, commonly called an IOLTA (Interest on Lawyers' Trust Accounts) account, kept entirely apart from your operating account. Commingling client funds with firm funds is one of the fastest ways to draw a bar complaint, even when it happens through simple bookkeeping carelessness rather than intent. The specific recordkeeping requirements — how long you must retain reconciliation records, what counts as an acceptable accounting method, whether three-way reconciliation is mandatory — vary by state, so set this up with guidance from your state bar's trust accounting rules rather than assuming your bank's standard business account setup is sufficient . Open the trust account at a bank your state bar has approved for IOLTA purposes — not every bank offers an IOLTA-compliant account, and some require the bank itself to be on an approved list before you can open one there . Alongside the trust account, open a separate operating account for firm revenue and expenses, and if you've formed a PLLC or PC, keep a clean line between firm funds and your personal accounts — the same corporate formalities that protect your liability shield in any business apply here, and sloppy bookkeeping between the two can undermine that protection in addition to creating a compliance problem. 5. Decide how you'll manage cases, time, and billing Before you take your first case, you need a system for tracking deadlines, matters, time entries, and invoices — doing this on paper or in a general-purpose spreadsheet becomes unmanageable within your first few months of real caseload. Most new firms choose cloud-based practice management software that combines case management, time tracking, billing, and often trust accounting in one place. If you're comparing specific platforms, our comparison of Clio, MyCase, and PracticePanther walks through how the major options differ on pricing and features . Whichever you choose, the deciding factors are usually billing style (hourly vs. flat-fee vs. contingency), whether it integrates with your trust accounting setup, and how much client-facing portal functionality you want from day one. Don't underweight the client portal piece — a portal where clients can see billing, upload documents, and message you directly cuts down on the phone-tag and "what's the status of my case" calls that otherwise eat a disproportionate amount of a solo practitioner's day. Whatever system you choose, confirm it has reasonable security practices before you put client data in it — encryption at rest and in transit, and ideally two-factor authentication for your own login, since a data breach involving client files is both a confidentiality problem under Rule 1.6 and a reputational one. 6. Decide on office space — or whether you need any A growing share of new solo practices start as virtual or home-office operations, sometimes using a registered agent address and a shared conference room service for client meetings and depositions, which keeps fixed overhead low while you build a caseload. Some practice areas — litigation-heavy work with frequent in-person client meetings, or anything requiring secure physical file storage for sensitive records — push firms toward a physical office sooner. Either way, confirm your state bar's rules on advertising a business address and signage before you print anything, since a few states have specific requirements for how a law office must be identified at its physical location . If you go virtual, think through where you'll meet clients who expect an in-person option — a co-working space with bookable private rooms, a shared suite with other solo practitioners, or an arrangement with a colleague's office are all common solutions that don't require signing a long commercial lease before you have a caseload to support it. Whatever you choose, make sure the address you use on your Google Business Profile and bar filings is one you can receive mail at reliably and consistently, since a mismatch between your listed address and your actual practice location can create problems on both fronts. 7. Build an engagement letter and intake process before you need one Every new client relationship should start with a written engagement letter spelling out scope, fees, and what happens if the matter is terminated early — doing this consistently, from your very first client, is both an ethics safeguard and a basic business practice. A rushed, undocumented intake is where a lot of new-firm malpractice exposure originates, not from losing a case on the merits. Our guide on law firm client intake, scripts, and follow-up covers building a repeatable intake process, including the point at which you capture client feedback as a matter closes — which matters for the next section too. Build a basic conflict-check process at the same time, even as a solo practitioner — a simple, consistently maintained spreadsheet or the conflict-check feature in your practice management software of adverse parties and client names you've represented is enough at this stage, as long as you actually check it before accepting every new matter. 8. Decide whether and when to hire Many new firms start as a true solo operation and bring on help only once revenue supports it, typically in this order: a part-time or virtual paralegal or legal assistant to handle intake, scheduling, and document prep; then a bookkeeper once trust and operating account reconciliation becomes time-consuming; and an associate attorney only once caseload consistently exceeds what one lawyer can responsibly carry. Resist the temptation to hire ahead of revenue in the first year — overhead is the single biggest threat to a new solo practice's cash flow, and it's easier to add staff once you have a predictable caseload than to carry payroll through a slow stretch. 9. Budget realistically for startup costs Startup costs for a solo practice vary enormously by practice area, state, and whether you're renting office space, and any specific dollar figure quoted without a named source and year should be treated skeptically . The recurring cost categories to budget for are consistent regardless of practice area: bar dues and CLE, malpractice insurance premiums, practice management and e-discovery software subscriptions, a business phone and client communication system, basic marketing (a website and your Google Business Profile at minimum), and a cash buffer for the months before billing catches up to expenses. Build the budget around those categories rather than a single all-in number, since the mix shifts a lot between a solo immigration practice run from home and a two-partner litigation shop renting downtown office space. A conservative approach is to assume minimal revenue for the first three to six months while referrals and your reputation build, and to have a personal or business cash reserve that covers fixed costs for that stretch rather than counting on billing to keep pace from week one. 10. Set up a website, email, and basic technology before you open A simple, accurate website — practice areas, attorney bio, contact information, and a way to request a consultation — is table stakes before you take your first client call, and it doesn't need to be elaborate to do its job. Use a professional email address on your own domain rather than a generic free-email account; it's a small detail that affects how seriously prospective clients and opposing counsel take your firm from the first message. Set up secure, encrypted file-sharing for sensitive documents rather than relying on unencrypted email attachments, and confirm whatever video-conferencing and e-signature tools you adopt meet your state bar's guidance on client confidentiality for electronic communications . 11. Build your firm's reputation from day one Marketing a brand-new firm with zero track record is harder than marketing an established one, which is exactly why the reputation work should start with your very first client rather than after your first dozen. Claim and complete your Google Business Profile the same week you open — it's the first thing most prospective clients will check, and an unclaimed or sparse profile looks indistinguishable from a firm that isn't really open yet. Do the same for Avvo, Justia, and Martindale-Hubbell; a complete profile on each, even before you have any reviews, establishes that your bar admission, practice areas, and contact information are accurate and current. Pick your Google Business Profile category carefully — "Lawyer" is the broad default, but several more specific categories exist for practice areas like family law, personal injury, criminal defense, and immigration, and the more specific category tends to match search intent better once prospective clients start comparing firms in your area. Then build the review-request habit before you need it, not after a client complains that you never asked. The ABA Model Rules generally permit asking clients for reviews, with two firm boundaries regardless of state: never offer anything of value in exchange for a review under Rule 7.2(b), and ask every client the same way at the close of the matter — win, lose, settle, or withdraw — rather than only after a good outcome, since outcome-based solicitation is review gating and a separate problem under FTC and platform rules. Set up a direct link or QR code for your Google review page now, so the request is a one-click action you can send the moment a matter closes instead of something you have to look up each time.

Do you need malpractice insurance to open a solo law practice? In most states it isn't strictly mandatory, but a few states require either coverage or a written disclosure to clients if you're going without it, and going without it as a brand-new solo practitioner is a significant personal financial risk regardless of what your state technically requires . Get quotes before you finalize your entity paperwork, since the lead time on a policy is usually shorter than people expect, but it's one more thing to sequence correctly rather than leave for your first week of practice. How much does it cost to start a solo law practice? It depends heavily on practice area, state, and whether you rent office space, and there's no single reliable figure that applies across jurisdictions — treat any specific number you see quoted elsewhere with skepticism unless it cites a named, dated source. Budget by category instead: bar dues, malpractice insurance, practice management software, a business phone line, a basic website and Google Business Profile, and a cash buffer for the ramp-up period before billing catches up to expenses. Can I start asking for reviews before I have any client history? Yes — there's no minimum caseload or time-in-practice requirement for claiming your Google, Avvo, or Justia profiles and starting to request reviews once your first matters close. The same rules apply from day one as they do for an established firm: ask every client the same way regardless of outcome, and never offer anything of value for a review. Do I need a separate trust account if I only take flat fees? It depends on your state's rules and on whether the flat fee is treated as earned on receipt or held until the work is complete . Some states allow flat fees to be deposited directly into the operating account if specific conditions are met and disclosed in the engagement letter, while others require any fee that hasn't yet been fully earned to sit in trust regardless of whether it's structured as flat or hourly. Don't assume a flat-fee structure lets you skip the trust account question — confirm the rule with your own state bar before you take your first flat-fee retainer. Should I form my entity before or after getting malpractice insurance? Most lawyers get malpractice insurance quotes while the entity paperwork is still in progress, since the lead time on underwriting can take longer than expected and you don't want it to be the thing blocking your opening date. The entity itself is usually faster to form — in many states a PLLC or PC filing processes in days to a few weeks , while insurance underwriting can take longer depending on the carrier and your practice area.
