Legal assistants are hired by the people who run the firm's support staff, not by the attorneys they will support. At a larger firm that is the legal support manager (sometimes called the secretarial services or practice support manager), who assigns assistants to attorneys and balances the load. At a small or mid-size firm, usually an LLP or a professional corporation, it is the office manager or firm administrator, with the supervising partner meeting finalists. The attorney has a strong voice, often a veto, but rarely runs the search. Legal recruiting, where it exists, focuses on lawyers.

What Ad Call gives you for a legal assistant ad
For legal assistant ads Ad Call leads with the legal support manager at larger firms and the office manager or administrator at smaller ones. The signals help you connect the ad to an attorney move: how long the ad has been live, whether the firm is running several assistant ads, and which practice the ad names.
- An assistant ad that follows a lateral announcement is a seat the arriving partner needs on day one.
- Twelve days in, the manager is still screening and has not yet settled on anyone: the best moment to put one strong candidate in front of them.
- The ad names real estate and finance: an assistant who has handled closing documents and lender forms is an easy yes to an interview.
The announcement, then the ad
A mid-size Denver firm posts a short item: a real estate partner is joining from a competitor, bringing two associates and a book of lender clients. The legal support manager reads it at 8 a.m. and does the math. Her assistants already each support several attorneys. Three new lawyers arriving in a month means at least one more assistant, maybe two, and she needs someone who can handle closing binders and lender forms from day one.
By Thursday there is an ad. By the following Tuesday she has eighty applicants, most of them from outside law, and no time to read them because she is also setting up three new workstations, filing accounts and document-system access for the arriving attorneys.
The recruiter who calls her that Tuesday with one real estate legal assistant, already experienced in the document system the firm uses, gets a meeting. The recruiter who calls three weeks later, after the partner arrives, is competing with a candidate the partner brought along or an internal transfer. The lateral announcement is the start of the clock.
Why lateral moves drive legal assistant hiring
Legal assistants are the thinnest layer of law-firm staffing, so any attorney movement tips the ratio. In a 2020 column in the Association of Legal Administrators' Legal Management magazine, the author observed that the old one-lawyer-to-one-secretary model has been replaced at many firms by a leaner ratio of six or seven lawyers per secretary. The Thomson Reuters Institute's Staffing Ratio Survey reported secretarial and word processing roles declining 4.7% a year on average from 2017 to 2022. Fewer assistants per lawyer means each arrival or departure is felt immediately.
And lawyers are moving. Firm Prospects reported that lateral partner hiring in the AmLaw 200 market it tracks hit a five-year high in 2025, with 3,009 partner moves, a 10% increase over the prior year; litigation led at 26% of partner hires, followed by corporate at 16%. Each of those moves is an arrival at one firm and a departure at another, and both ends can create an assistant req: the gaining firm needs support, and the losing firm may lose an assistant who follows the partner.
The occupation as a whole is not growing. The BLS Occupational Outlook Handbook projects little or no change in employment of paralegals and legal assistants from 2025 to 2035, with about 40,800 openings a year, mostly from replacement. That is exactly why movement is the signal: in a flat market, openings follow people.
How to use it: watch firm news in your city for lateral arrivals and departures, note the practice group, and call the legal support manager or office manager within a week. Ask whether the arriving partner is bringing an assistant; if not, you have a practice-matched candidate ready.
What to confirm before you pitch a legal assistant
Legal assistants are judged on the firm's systems and the practice's rhythm. A manager will screen on these in the first five minutes; you should too.- Practice area. Litigation calendars and court filing are different work from real estate closings, estate planning or corporate minute books. Match it to the ad and to the arriving partner's practice.
- Document management system. Ask the candidate which system they profile, version and file documents in every day. A candidate who already knows the firm's system needs no ramp-up; say so in the first sentence.
- Time entry and billing. Many assistants enter or clean up attorneys' time. Confirm which time-entry and billing software they have used and whether they have handled prebills.
- E-filing and court rules. For litigation, ask which courts they have e-filed in, state and federal, and whether they have managed deadline calendars.
- Number of attorneys supported. Ask how many attorneys they supported at once and at what level. With lean ratios, this is the question managers care about most.
- Dictation and transcription. Some senior partners still dictate. If the arriving partner is one, it matters.
- Why they are leaving. If the candidate's own partner just left their firm, say so honestly; it explains the move and shows availability without drama.
- Law-firm experience versus in-house. Corporate legal departments run differently. If your candidate is coming from in-house, be ready to explain how they handled billable-hour pressure, or pick another candidate.
The call: legal support manager, the week of the announcement
Law-firm receptionists route recruiter calls to HR or legal recruiting by reflex. Ask for the staff side by name and title, and mention the practice group.Questions recruiters ask about legal assistant reqs
- Who hires legal assistants at a law firm?
The legal support manager at larger firms and the office manager or firm administrator at small and mid-size firms, with the supervising attorney meeting finalists and often holding a veto. Legal recruiting at big firms usually focuses on attorneys, not staff.
- Is a legal assistant the same as a legal secretary?
Many firms use the titles interchangeably for administrative support to attorneys, and some have renamed legal secretaries as legal assistants. Others use "legal assistant" for a paralegal-like role. Read the duties in the ad before you pitch: if it asks for legal research or drafting, you are really filling a paralegal seat, and the supervising attorney will want to decide.
- What is the best time to contact a legal assistant hiring manager?
Within a week of a lateral announcement, and mid-morning Tuesday through Thursday. Avoid month-end, when legal support teams are pushing time entry and bills out, and the first day or two after a big group arrives, when the manager is busy onboarding.
- How do I find the legal assistant hiring manager's email?
Ad Call hands back the legal support manager or office manager for each firm running a legal assistant ad, with name, title, email and office line, graded by confidence.
