The hard part of opening a firm is rarely the law. It is the order of operations. Which registrations come first. Which accounts must exist before you take a dollar from a client. Which choices lock you in later.
This walks through what to arrange, what it costs, and the sequence to do it in. If you are still weighing whether to go out on your own, start there instead.
Key Takeaways:
- Licensing comes first. You need admission in every state where you will practice, and in many states the firm itself registers too.
- Entity choice is restricted. Most states limit which business structures a law firm may use, so check before you file.
- Client money is separate money. Retainers and settlement funds go in a trust account, never in your operating account.
- Insurance is close to mandatory. Some states require malpractice cover. Others require you to tell clients you have none.
- Most costs recur. Software, insurance, and registrations renew. The one-time filing fees are the small part.
- Other people control your timeline. Bar and state registrations gate everything else.
What Does It Take to Start a Law Firm?
Starting a law firm takes five things. A plan for what you practice and who you serve. The licenses to operate. Your bank and trust accounts. The systems you run on. A way to reach clients. Each phase depends on the one before it.
Most people start at phase four because buying software feels like progress. Phase two is what actually takes time, and it is the one you cannot rush.
What Do You Need Before You Can Open?
Before you take a client, four things must be in place. Bar admission in every state where you will practice. A registered business entity. An EIN from the IRS. And any firm registration or trade name approval your state bar asks for. Some cities and counties add a local business license on top.
The usual list:
- Bar admission, in each state where you will practice law
- Firm registration with the state bar, where your jurisdiction requires it
- Trade name approval, since most states restrict what a firm may call itself
- Entity registration with the secretary of state
- An EIN, needed to open business and trust accounts
- Local business licenses, which vary by city and county
Rules differ by state, and they change. Your state bar is the authority on all of it. Call them before you file anything, not after.
How Much Does It Cost to Start a Law Firm?
What you spend turns on one choice more than any other: whether you take an office. The required items are small and mostly fixed. The expensive ones are optional. Space, staff, and advertising.
The pattern worth noticing: almost everything on this list is recurring. Filing fees are one-time and small. Insurance, software, and bar dues come back every year, so the question to plan around is monthly burn rather than startup cost. Our law firm budgeting guide covers how to build that out.
Can You Start a Law Firm With No Money?
Not for nothing, but for far less than it once took. A remote practice removes most of the old costs. No lease. Software billed monthly. Hourly support instead of salaried hires. What you cannot skip is registration fees, insurance, a trust account, and a website.
The practical version is that you trade fixed costs for variable ones. No office, no payroll, no long contracts. Scale what you spend to what you bill, and keep the commitments short until the caseload is steady.
What Legal Structure Should You Choose?
Most solo and small firms use a PLLC or a professional corporation. Many states bar lawyers from using a standard LLC. And no structure anywhere shields you from your own malpractice. Check what your state allows before you file.
This is about the legal entity, not about who reports to whom. For how a firm organizes its people as it grows, see how a firm is structured internally.
Entity choice has tax consequences that outlast the decision. Worth an hour with an accountant before you file, not after.
How Do You Handle Client Money?
Client funds never touch your operating account. Retainers, settlement proceeds, and advances for filing fees go into a client trust account, usually an IOLTA. Money moves out only once it is earned, and you keep records of every movement.
This matters more than almost anything else here. Mixing client money with firm money is one of the most common grounds for discipline. It does not take bad intent. A solo who pays a filing fee from the wrong account has a problem either way.
The principles are consistent everywhere:
- A separate account for client funds, opened as a trust account
- No firm money in it, and no client money outside it
- A record for every deposit and withdrawal, by client and matter
- Regular reconciliation, not an annual catch-up
The specifics, including record retention periods and reporting, are set by your state bar. Get those directly from the bar rather than from a template you found online.
What Insurance Does a New Firm Need?
Malpractice insurance comes first. Some states require it to practice. Others require you to disclose to clients that you do not carry it, which is its own kind of requirement.
Most firms add two more. General liability, if you meet clients anywhere. And cyber cover, now standard for anyone holding client data. Get quotes before you open, because cover can take longer to arrange than you expect.
Where Will the Firm Operate?
Three options: a leased office, shared or coworking space, or fully remote. Remote is now normal rather than unusual, and it removes the largest fixed cost a new firm carries. Shared space is the middle route when you need somewhere to meet clients occasionally.
The software is much the same either way. Practice management for matters and deadlines. Document storage. E-signature. Accounting that tracks trust balances. A business phone line that is not your mobile. Pick tools that work together. Moving later is painful.
How Do You Get Your First Clients?
Early work comes from people who already know you. Former colleagues, referral relationships, and local bar connections do more in year one than any campaign. Build the digital foundation alongside that: a website that answers what a client actually asks, and a Google Business Profile for local search.
That is enough to open with. When you are ready to plan properly, our law firm marketing plan goes deeper, and what a law firm website needs covers the site itself page by page.
How Long Does It Take to Open?
Sequence matters more than a week count. The slowest steps are not yours to control. Bar admission and firm registration run on the state's schedule. Entity formation runs on the secretary of state's. Insurance underwriting takes as long as it takes.
Everything else can run in parallel. Choose software, build the website, and set up accounts while the registrations are pending. Start the gating items first and the rest will not be what holds you up.

Frequently Asked Questions
How long does it take to start a law firm?
It depends on the steps other people control. Bar and firm registration, entity formation, and insurance underwriting each run on someone else's schedule. The work you control, software and website, can happen in parallel while those are pending.
Do you need an office to start a law firm?
No. Fully remote practice is common now, and it removes the largest fixed cost a new firm carries. Shared or coworking space is a middle option if you need somewhere to meet clients.
Can you practice in more than one state?
Only where you are admitted. Practicing without admission is unauthorized practice. The rules for work across state lines are specific, so check with the bar in each state first.
What does it cost to run a law firm each month?
Recurring costs dominate. Software, insurance, bar dues, hosting, and any space or staff. Most of the expense repeats, so monthly burn is a more useful number to plan around than a startup total.
Do you need staff on day one?
Usually not. Most solos start alone and add support when the admin work starts eating billable hours. The first hire is typically intake or an assistant rather than another attorney.
What is the most common first-year mistake?
Mishandling the trust account. It is rarely deliberate, which is exactly why it happens so often. Set the account up correctly before the first retainer arrives and reconcile on a schedule.
When the Admin Starts Eating Your Billable Hours
Most new firms hit the same wall. The caseload grows, the admin grows faster, and the person doing both is the one who should be practicing law.
Legal Soft places pre-vetted intake specialists and legal assistants who work only for your firm, so you can add support without adding a payroll line you are not ready for.
