A New Lawyer's First 90 Days: What the Firm Should Set Up

Chief Product Officer · Attornaid

A new lawyer's first 90 days measure the firm's capacity to teach more than the new lawyer's ability to learn. The firm should have five things in place: access and tools ready on day one, a named mentor, responsibility that grows in stages, written feedback at fixed points and a 90-day review that leads to a decision. Without them, the new lawyer learns by copying whatever work happens to be nearest, and that work is not always a good example.

Law firms usually manage hiring well and onboarding badly. The new person is given a desk and a file, and the rest is expected to follow. It does follow, but how long it takes and which habits come with it are left to chance. The plan below gives one framework for a trainee, a newly qualified lawyer and an experienced lateral hire; only the depth changes from person to person.

Day one: what must be ready

The aim of the first day is not to teach the work but to make the new lawyer able to work. Everything below should be ready before they arrive.

Item	Why on day one
Email account and signature	External communication is not held up
Practice software account and permissions	To open a matter file at all
Scope of matters they can access	Access is defined at the start, not later
Court e-filing access	Requests can take days; start them before the first day
Admission and registration formalities in your jurisdiction	Everyone knows what the new lawyer may sign, file or attend
Desk, keys, access card	To work without waiting for someone
Internal communication channels	The route for asking questions is known
AI usage policy	Read and acknowledged from the first day

Two of these items depend on outside bodies rather than the firm. Court e-filing access and the admission and registration formalities in your jurisdiction can take days or weeks, so they should be started as soon as the offer is accepted. Until they are complete, the mentor and the supervising lawyer should both know exactly which tasks the new lawyer can and cannot take on.

Common mistake: Opening permissions only as the need arises. It forces the new lawyer to interrupt someone at every step and wears down their willingness to ask questions. Define the scope of access at the start and widen it later.

The first month: a named mentor and a fixed rhythm

A named mentor

Name one person the new lawyer takes questions to. Saying they can ask anyone means, in practice, they can ask no one: a question that is nobody's responsibility goes unasked. The mentor does not need to be the most senior lawyer in the firm. They need time set aside for the role and a clear understanding that the role is theirs.

A fixed feedback rhythm

A fixed fifteen-minute meeting once a week is enough. What matters is not its length but that it happens every week and is not cancelled when the workload rises.

Week 1: do the tools work, who is who, where to find what.
Weeks 2 and 3: concrete feedback on the first pieces of work, based on examples rather than general impressions.
Week 4: the first-month review, written down, with the plan for the next stage of responsibility.

Beyond the weekly meeting, feedback should be written down at fixed points: the end of week 4, the end of week 8 and day 90. A few lines are enough: what is working, what should change and what responsibility comes next. Spoken feedback fades for both sides within weeks. Written feedback gives the new lawyer something to return to and gives the 90-day review a record to work from instead of memory.

Feedback should address the work, not the person. A note that the relief sought in a draft is unclear teaches something; a remark that the new lawyer is careless teaches nothing.

The first three months: responsibility in stages

Responsibility should be handed over in stages, not all at once. The staging below suits most firms.

Period	Responsibility	Check
Weeks 1 to 4	Research, summaries, file review	Every output is reviewed
Weeks 5 to 8	Drafting, attending hearings alongside a senior lawyer	Drafts are reviewed together
Weeks 9 to 12	Running simple matters independently	Weekly matter review

For an experienced lateral hire the stages can be compressed from weeks into days, but they should not be skipped. An experienced lawyer still has to learn how the new firm numbers its files, records its deadlines and talks to its clients. Moving from one stage to the next should be a decision taken at a written feedback point, not something that happens because the workload pushed it.

Five things to put in writing

What makes onboarding scale is being able to point each new person to a written source instead of explaining everything from scratch. Five documents are the minimum.

File organisation: numbering, folder structure, naming conventions.
Deadline tracking: where deadlines are recorded, who records them, how reminders are set.
Document templates: which template is kept where and when it is used.
Client communication: who calls the client, how often clients are updated, which matters are confirmed in writing.
AI usage policy: which work it may be used for and how its output is verified.

Documents that update themselves: Ask every new joiner to note, during their first month, whatever they found missing or unclear in these documents. The person who sees a gap most clearly is the one reading the document for the first time.

The 90-day review

The review at day 90 should end in a decision, not just a conversation. It works from the written feedback of weeks 4 and 8 and covers five points.

Which types of work the new lawyer can now handle independently, and which not yet.
Which questions kept recurring. They show where the written documents have gaps.
Whether the feedback rhythm held, and how many meetings were cancelled.
Whether the staged responsibility plan progressed as intended.
The new lawyer's own assessment. This is the point most often left out.

The answers lead to one of three outcomes, recorded in writing. The new lawyer moves to independent work on named types of matter; or a stage is extended, with the specific gap and a new review date stated; or the firm and the new lawyer conclude that the role does not fit and agree the next step. Where employment terms include a probationary period, the review should be scheduled early enough that this decision is not made under time pressure.

The review also covers the firm. If the mentor had no time, meetings were cancelled or the documents were missing, that is a finding about the firm's onboarding, not about the new lawyer.

Checklist

Have email, practice software, permissions and the scope of access ready before day one.
Start court e-filing access and the admission and registration formalities in your jurisdiction as soon as the offer is accepted.
Name one mentor and set aside time for the role.
Put a fifteen-minute weekly feedback meeting in the calendar for the first three months.
Write feedback down at the end of week 4, the end of week 8 and day 90.
Agree the staged responsibility plan and the point at which each stage begins.
Keep the five core documents in writing and ask each new joiner to note their gaps.
End the 90-day review with a written decision.

Frequently asked questions

What should be ready on a new lawyer's first day?

An email account and signature, a practice software account with defined permissions, the scope of matters they can access, court e-filing access, a desk and keys, the internal communication channels and the AI usage policy. The admission and registration formalities in your jurisdiction should also be confirmed, so everyone knows what the new lawyer may sign or attend. Opening permissions only as the need arises is a common mistake: it makes the new lawyer interrupt someone at every step and discourages questions.

Why does a new lawyer need a named mentor?

Without a named person to take questions to, a new lawyer tends not to ask them. Telling someone they can ask anyone means in practice they can ask no one, because a question that is nobody's responsibility goes unasked. A named mentor gives every question an address.

How often should a new lawyer get feedback?

A fixed fifteen-minute meeting once a week is enough in most cases, as long as it is not cancelled because of workload. At fixed points, the end of week 4, the end of week 8 and day 90, the feedback should also be written down. Feedback should address the work rather than the person and rest on a concrete example instead of a general judgement.

How quickly should a new lawyer's responsibility increase?

In stages: research, summaries and file review in weeks 1 to 4; drafting and attending hearings alongside a senior lawyer from week 5; running simple matters independently from week 9. For an experienced lateral hire the stages can be compressed from weeks into days, but they should not be skipped. An experienced lawyer still has to learn how the new firm works.

Which onboarding documents should a law firm have in writing?

At least five: file organisation (numbering, folder structure, naming), deadline tracking (where deadlines are recorded and who records them), document templates, client communication rules and the AI usage policy. Written documents let the firm point each new person to a source instead of explaining everything from scratch, which is what makes onboarding scale.

What should the 90-day review lead to?

A written decision, not just a conversation: which types of work the new lawyer now handles independently, which stage is extended and until when, or whether the role fits at all. The review works from the written feedback of weeks 4 and 8 rather than from memory. Questions that kept recurring during the 90 days also show exactly where the firm's written documents have gaps.
