Law Firm Client Onboarding Checklist: Conflict Checks to Kickoff

TLDR: A law firm intake is a sequence of compliance gates, and skipping any one of them creates real exposure. This checklist walks the onboarding in order (conflict check, engagement letter, identity and KYC, retainer and trust deposit, matter document collection, secure portal handoff, and internal matter setup) so every client moves through the same steps and nothing slips.

Every new matter starts the same way. Someone needs help, the phone rings, and there is pressure to get moving. The problem is that the fastest path to trouble in a law firm is starting substantive work before the intake steps are actually done.

A checklist fixes that. Not a mental checklist, and not a list that lives in one attorney’s head. A written, repeatable sequence that every new client runs through in the same order, every time. This is that sequence.

For the broader reasoning behind why a legal intake needs a system at all, see our overview of client onboarding for law firms. This article is the concrete step-by-step version you can actually run.

How to Use This Checklist

Work it top to bottom. Each step is a gate, which means you do not move to the next one until the current one is genuinely complete. The order matters because the early steps decide whether you can ethically take the client at all, and the later steps decide whether you can serve them well.

Do not let a step sit half-finished while you start on the next. That is exactly how an unsigned engagement letter and a cleared conflict check end up living side by side while real work is already underway.

Step 1: Run the Conflict of Interest Check First

Before anything else, run conflicts. Not after the intake call feels promising. Not once the retainer clears. First.

To run a clean check you need a short intake form that captures:

• Full legal name and any prior or alternate names
• Opposing parties and their counsel, if known
• Related entities, businesses, or individuals
• Referring party, if there is one
• A one-line description of the matter

Run that against your conflict database. If the check is clear, continue. If it is not, you stop here, and you document why.

Do not give substantive advice before this step clears. A missed conflict is not an inconvenience. It is an ethics problem and a potential disqualification.

Step 2: Send the Engagement Letter and Fee Agreement

Once conflicts are clear, the engagement letter goes out immediately. It defines the relationship and protects the firm, and no meaningful work should begin without a signed one on file.

The letter should spell out:

• Scope of representation, including what is expressly out of scope
• Fee structure, whether hourly, flat, contingency, or a retainer arrangement
• Billing terms, including invoice timing and what happens with unpaid balances
• Communication expectations and response times
• Termination provisions for both sides
• Client responsibilities, including what you need from them and when

Track it as three separate states, not one. Sent, signed, and filed are different things, and “I emailed it last week” is not the same as having a signature in the file.

Step 3: Verify Identity and Run KYC or AML Checks

Depending on your practice area and jurisdiction, you may be obligated to verify who your client actually is. Real estate, trusts and estates, immigration, and anything touching the movement of funds are common triggers.

At minimum, collect and record:

• Government-issued photo identification
• Confirmation of legal name and date of birth
• For entity clients, proof of authority to act (formation documents, an authorized signatory)
• Any source-of-funds documentation your obligations require

Do not treat this as paperwork you can backfill later. If a check reveals a problem after you have taken a retainer and started work, unwinding it is far messier than a clean gate at the front.

Step 4: Collect the Retainer and Fund the Trust Account

With the engagement signed and identity confirmed, collect the retainer. This is a hard gate for a reason: it confirms the client is committed and it keeps you on the right side of trust accounting rules.

Handle this step carefully:

• Deposit advance fees into your client trust account (IOLTA), not your operating account
• Record the deposit amount, date, and matter it belongs to
• Confirm the funds have actually cleared before you rely on them
• Note the replenishment threshold, so you know when to ask for more

Getting trust accounting right from the first deposit is far easier than reconciling a tangle of commingled funds later.

Step 5: Send a Specific Matter Document Request

Now collect the documents the matter actually needs. The single biggest failure here is vagueness. “Please send any relevant documents” produces a slow trickle of the wrong files.

Be specific and prioritized instead. Depending on the matter, you are likely requesting:

• Financial records (tax returns for named years, bank statements, financial statements)
• Prior filings and court documents
• Contracts, leases, or agreements at issue
• Correspondence, including anything from opposing counsel
• Insurance policies
• Any authorizations you need signed to obtain third-party records

Name each item precisely. “Federal tax returns for 2022 through 2024.” “The signed lease dated March 2024.” “Medical records from Dr. Smith for January through June 2025.” Then tell the client what you need first versus what can wait.

Step 6: Hand Off a Secure Upload Portal

Email is not an acceptable channel for legal documents. Client files routinely include financial records, medical records, and identification, and those cannot travel through plain inboxes.

Give the client one secure place to upload everything, with encryption in transit and at rest. One link, one destination, one status view. That does three things at once: it protects privileged material, it keeps every file for the matter in a single location, and it gives you a clear picture of what has arrived and what is still outstanding.

This is where a tool earns its keep. With OnboardMap, you describe the intake in a sentence and it builds the whole thing, the checklist, the intake forms, the document requests, and a branded upload portal. You send the client one link, and it tracks every step, reads what they upload, and sends the reminders so you are not the one chasing.

Step 7: Set Up the Matter Internally and Kick Off

Once the priority documents are in, complete the internal setup that turns an intake into a live matter:

• Open the file in your practice management system
• Assign the team, including lead attorney, associate, and paralegal
• Calendar every critical deadline, especially the statute of limitations and any filing or court dates
• Build the task list in the order work needs to happen
• Complete the client information record, so contact details and related parties are captured for every future filing

Then close the loop with the client. Confirm the engagement is active, introduce the assigned team, lay out what happens next, list anything still outstanding, and tell them when to expect their next update. That kickoff message is what makes a client feel represented rather than processed.

Make the Checklist Run Itself

A checklist only prevents mistakes if someone actually follows it on every matter. The firms that get burned are rarely the ones without a process. They are the ones with a good process that quietly gets skipped when things get busy.

That is the case for building the sequence into a tool instead of a document. OnboardMap turns this whole checklist into a repeatable flow, one link to the client, live tracking of every step, and reminders that go out on their own so no compliance gate gets left half-open. Your first onboarding is free, then it is a flat $12 per onboarding with no subscription, which makes it easy to run a client or two through before you commit.
