Part-Time vs Full-Time Staff for Solo Attorney Practices
Compare part-time vs full-time staff for solo attorneys: costs, benefits, and practical steps to decide what fits your practice in 2026.
Deciding between part-time and full-time staff is one of the first major business calls you’ll make as a solo attorney. The right choice depends on your caseload, revenue stability, and how you work best. This guide breaks down the real costs, trade-offs, and steps to help you decide what fits your practice in 2026.
Why Staffing Matters for Solo Attorneys
As a solo, you wear every hat: lawyer, marketer, bookkeeper, and office manager. Adding staff frees you to focus on billable work, but it also adds fixed costs. The key is matching your staffing model to your actual workflow. A part-time hire might cost $20,000 to $35,000 per year, while a full-time employee runs $45,000 to $70,000 plus benefits. Getting this wrong can drain your cash flow or leave you buried in admin work.
Part-Time Staff: Pros, Cons, and Costs
Part-time staff typically work 15 to 29 hours per week. They are ideal for practices with variable caseloads or when you need specialized help without a full-time commitment.
Pros:
- Lower base salary: $18 to $28 per hour for a legal assistant, so $15,000 to $30,000 annually.
- Flexibility: Scale hours up or down as caseloads change.
- Fewer benefits: Part-time employees often don’t qualify for health insurance or retirement matches, saving 15% to 25% of payroll.
- Easier to terminate: Less commitment, simpler separation.
Cons:
- Limited availability: They may not be reachable for urgent client calls or court filings.
- Less continuity: You may need to retrain if turnover is high.
- Scheduling complexity: Coordinating hours can be a headache.

How to Decide: A Practical Framework
Use these three steps to make the right call for your practice.
Step 1: Track your time for two weeks. Log every hour you spend on non-billable tasks like scheduling, client calls, filing, and bookkeeping. If you spend more than 10 hours per week on admin, you likely need help.
Step 2: Calculate your break-even point. Estimate how many additional billable hours you could work if you offloaded admin tasks. For example, if you bill $250 per hour and can free up 5 hours per week, that’s $1,250 in extra revenue. Compare that to the weekly cost of a part-time hire (about $430 to $550). If the extra revenue exceeds the cost, hiring makes sense.
Step 3: Start part-time, then scale. Unless you have a guaranteed caseload, begin with a part-time hire. Many solos find that 20 to 25 hours per week is enough. As your practice grows, you can increase hours or convert to full-time.
When to Choose Part-Time
Choose part-time if you:
- Have a caseload that fluctuates seasonally.
- Are just starting out and need to control costs.
- Only need help with specific tasks like intake or billing.
- Prefer to handle client communication yourself.
When to Choose Full-Time
Choose full-time if you:
- Have a steady stream of cases that keeps you busy 40+ hours.
- Want a dedicated person to manage client relationships.
- Are spending more than 15 hours per week on admin.
- Have the revenue to cover the higher cost without stress.
Practical Steps You Can Take This Week
- Write a job description for the role you need, listing specific tasks and required hours.
- Set a budget based on the cost ranges above, and decide on a maximum monthly payroll.
- Post the position on legal staffing sites like LawJobs or local bar association job boards.
- Interview with a trial period in mind: offer a 90-day probationary period to test fit.
- Use a payroll service like Gusto or ADP to handle taxes and compliance from day one.
FAQ
Q: Can I hire a part-time employee and later switch to full-time? A: Yes, many solos start part-time and increase hours as the caseload grows. Just ensure your employee is open to the change and that your budget can handle it.
Q: What about independent contractors instead of employees? A: Contractors can be cheaper (no payroll taxes or benefits), but they must meet IRS criteria for independence. If you control their hours and work, they are employees. Misclassification can lead to penalties.
Q: How do I find reliable part-time staff? A: Use legal-specific job boards, local paralegal associations, or virtual assistant services that specialize in legal work. Ask for references and test their skills with a small project.
Q: What if I can’t afford any staff yet? A: Consider outsourcing specific tasks like bookkeeping or document review to freelancers. This costs $30 to $100 per hour but only when needed, keeping your overhead low.
The Bottom Line
For most solo attorneys, starting with part-time staff is the smarter move. It keeps costs manageable while giving you the support you need to grow. As your practice stabilizes, you can transition to full-time if the numbers justify it. Track your time, calculate your break-even, and make the decision based on data, not guesswork. Your goal is to maximize billable hours without overextending your budget.
