The short answer
Write down what you actually need when it comes to skills, experience, and tenure. Make sure you understand how the partner you're hiring for works, and hire the legal assistant whose working style is a fit, not just the one with the most credentials or who interviews the best. How someone handles a missed deadline, a last-minute pleading, or a conflicting instruction takes longer to see, and a small firm has no HR department to catch a poor fit early. By the time it becomes a problem, a partner has probably already lost billable hours to it.
Why this hire is hard right now
The pool of legal assistants is barely growing, so most hires are replacements. The US Bureau of Labor Statistics projects employment of paralegals and legal assistants to hold flat from 2025 to 2035 (about 404,900 to 403,800), yet it expects about 40,800 openings a year, mostly from people moving to other occupations or leaving the workforce. By our arithmetic, that is roughly one seat in ten turning over every year. For legal secretaries and administrative assistants, BLS projects a 5% decline. In Canada, Job Bank rates the outlook for legal administrative assistants in the Toronto region "moderate" for 2025 to 2027: a few new positions, several openings from retirements.
The work is changing as well. In a vendor survey of more than 1,300 legal professionals, 69% already use general-purpose AI tools at work, and 39% expect a reduction in paralegal or support roles. BLS makes the same point: AI is expected to make these workers more efficient and may soften demand.
If AI takes on more of the drafting and research, the human part of the job (judgment, communication, flagging problems) carries more weight, and that part runs on working style.
What a legal assistant does
The title covers at least three different jobs, and at a small firm one person often covers more than one. BLS counts paralegals and legal assistants as one occupation (files, research, drafting, court filings) and counts legal secretaries with administrative assistants in another, where legal secretaries prepare documents such as motions and subpoenas under a lawyer's or paralegal's supervision. In Canada, Job Bank files the role as administrative assistant, legal (NOC 13111). Ontario paralegals are a separate, licensed profession regulated by the Law Society of Ontario.
Before you write the posting, sort what you would hand off into three categories:
- Running the office: calendar, phones, client contact, billing entries, intake.
- Moving paper through a process: drafting from precedents, e-filing, tracking court and limitation deadlines.
- Handling a file: organizing productions, chasing documents, first-pass research.
The third category pushes the role toward paralegal or law clerk territory, and the pay with it. The second is where a missed step costs the most, so it matters most whether the person tells you early when something is slipping.
Working style: write it down first
Hand-off habits usually live in a partner's head, which makes them hard to screen for. Neither answer in the table is wrong. The trouble starts when two people with opposite answers share a desk.
Answer each row for every lawyer the person will support, separately.
| Moment | Write down, for each partner | What a mismatch looks like |
|---|---|---|
| Something goes wrong | Do you want to hear at once, or hear it with the fix already in hand? | The assistant fixes a missed step quietly for a day, and you learn about it from the client. |
| Instructions conflict | Who decides when two partners disagree, and should the assistant raise it or follow the one who asked first? | Work is done to the wrong instruction and surfaces at review. |
| Feedback | Do you mark up drafts line by line, comment sparingly, or redo it yourself? | Heavy mark-ups land as criticism, or silence is read as approval until a file goes wrong. |
| Speed against quality | Which files need fast and mostly right, and which need slow and exact? | Everything is treated as urgent, or everything is checked three times. |
Where partners answer differently, that difference is the brief.
The person you hire has to work with both, and a candidate who can describe how they adjust is worth more than one who says they are flexible.
What a bad hire costs
The most transparent estimate puts the cost of replacing an employee at about a fifth of their salary, and it is probably low. In a 2012 review by the Center for American Progress, the median across most jobs was 21% of annual salary, and 20% for jobs paying under US$50,000. Only 2 of the 11 research papers counted indirect costs such as lost productivity and lost clients. The data are historical and American, so read them as an order of magnitude. That doesn't count the cost of a partner's time and frustration, in the form of billable hours lost or business development time wasted, when there's friction or working styles clash.
What fit research does and doesn't show
Fit with a supervisor is a separate question. A 2005 meta-analysis of 172 studies found that it tracked how people felt about their supervisor (corrected correlation .46) and their job (.44), but much less how well they performed (.18) or how long they stayed (.09). Only 5 to 14 studies sit behind each of those four figures. The reasonable reading is that a mismatch is less likely to make someone bad at the work than to make the working relationship worse for both sides, and a partner lives with that every day.
How to screen for fit
Ask every candidate the same questions and score the answers against what you wrote down. A 2022 re-analysis of hiring research (Sackett and colleagues) ranked structured interviews first among the methods it reviewed, with a validity of .42, ahead of work samples at .33, as summarized by SIOP. Those figures cover job performance across occupations, not legal assistants specifically.
Questions that surface working style
Ask about a real past situation, then keep asking "what did you do next?" until you hear actions, not intentions.
- Something went wrong: "Tell me about the last time you found your own mistake after the work had gone out. What did you do first, and who did you tell?"
- Instructions conflicted: "Two lawyers gave you competing priorities on the same afternoon. What happened?"
- Feedback: "Which lawyer's way of giving feedback helped you most, and which was hardest to work with?"
- Speed against quality: "Describe a file where fast and exact pulled in different directions. Who decided, and how?"
A 30-minute work sample
Hand over a short mock file with two instructions that conflict and one fact missing. Watch whether the person asks, flags or guesses, and whether they tell you what they assumed. A guess said out loud is better than a silent one.
References
Ask a former lawyer: "What did this person need from you to do their best work?" The answer tells you whether you can supply it.
One last step: let the candidate meet the lawyers they would support, and ask each lawyer to describe how they hand off a file. You will see whether the answers in your table match what is said in the room.

FAQ
What is the difference between a legal assistant and a paralegal?
In Ontario, paralegals are licensed and regulated by the Law Society of Ontario and follow their own Paralegal Rules of Conduct. In the US, BLS reports legal assistants and paralegals as one occupation, so judge the job by its duties, not its title.
How much does a legal assistant cost?
Job Bank puts the Ontario median at C$26.44 an hour (2023 to 2024 data). BLS's May 2025 median is US$55,570 a year for legal secretaries and administrative assistants and US$62,890 for paralegals and legal assistants.
What should I ask in a legal assistant interview?
Ask about real past situations: finding their own mistake, conflicting instructions, feedback, and fast against exact. Use the same questions for every candidate and add a short work sample.
Should I hire for experience or for fit?
Both, in that order. Test the skills you need on day one with a work sample, then screen for how the person works with your lawyers. The supervisor-fit research links fit to how people feel about the working relationship far more than to performance, so fit does not replace skill.
Will AI replace legal assistants?
Nobody knows yet. BLS projects flat employment for paralegals and legal assistants through 2035 and says AI may reduce demand. In a vendor survey, 39% of legal professionals expected fewer paralegal or support roles and 22% expected more. Whatever happens, the person you want checks tool output instead of trusting it.
