Team sizes at law offices in Maryland
69.6% of Maryland's law offices with employees had fewer than five people in March 2023, compared with 71.8% nationally. 85.5% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.
| Employment size | Establishments | Share | U.S. share |
|---|---|---|---|
| 1–4 employees | 1,819 | 69.6% | 71.8% |
| 5–9 employees | 416 | 15.9% | 15.1% |
| 10–19 employees | 228 | 8.7% | 7.4% |
| 20–49 employees | 107 | 4.1% | 4.0% |
| 50 or more employees | 45 | 1.7% | 1.8% |

What law offices in Maryland use the phone for
Prospective clients often call a law office at a stressful moment and contact more than one firm, so the first firm to respond has an advantage. Attorneys are frequently in court or meetings, which makes accurate message taking and routing to the right paralegal essential.
Calls a law office in Maryland might handle in a typical week include:
- Someone calls after a car accident to ask whether the firm handles injury cases.
- A court clerk calls about a hearing date.
- The firm calls a prospective client back after an online inquiry.
Texting clients
Firms use texting for appointment reminders and document requests, keeping privileged discussion off text.
Texting from a local number in Maryland requires carrier registration (10DLC), a one-time $49 fee on Callata.
