Most law firm owners chase the practice areas everyone already knows how to run. The intake scripts exist. The referral networks are built. The fee structures are standard. But the real growth opportunity in legal services right now sits in the practice areas nobody has fully mapped yet — the ones where you have to build the playbook while you’re already representing clients.
That’s exactly the position civil rights attorney Caitlin Engstrand found herself in when she moved from public defense into a private practice handling trafficking, sexual assault, and platform liability cases. There was no established process for evaluating a decade-old trafficking claim against a compensation fund, no settled theory for holding platforms like Roblox or Meta liable when adults gain access to minors, and no template for running a civil case parallel to a criminal defense. She had to build it as she went. And that’s precisely why the practice works.
Why ‘No Playbook’ Is a Competitive Advantage, Not a Liability
When a practice area is crowded, you compete on price and marketing spend. When a practice area has no playbook, you compete on judgment and speed of learning. Firms that get comfortable operating without a template are the firms that end up writing the template — and owning the market position that comes with being first. If you’re evaluating a new niche and your hesitation is ‘nobody has done this before,’ treat that as a signal worth investigating, not a reason to pass.
Learn the Adjacent Doctrine Before You Build the Practice
Novel practice areas rarely stand alone. Engstrand’s cases pull from platform liability theory, Title IX and the special relationship doctrine in school cases, and Fourth and Fourteenth Amendment questions when school resource officers act under color of law. None of these bodies of law were written with her specific fact patterns in mind — she had to synthesize across them. Before you commit resources to a new practice area, map every adjacent doctrine your fact patterns will touch. That map becomes your actual competitive moat.
Build Referral Relationships With Attorneys Who See the Cases First
Criminal defense attorneys and family law attorneys routinely encounter facts that could support a parallel civil claim — they just aren’t set up to run with it. That makes them a natural referral source for a firm willing to take on the civil track. Rather than competing with generalist practices, position your specialty as the thing they hand off to, not the thing they lose business to. A single strong referral relationship with a busy criminal defense practice can outperform a paid marketing campaign.
Document Your Process As You Go So It Becomes Repeatable
The instinct in an undeveloped practice area is to treat every case as a one-off. Resist it. Every time you solve a new problem — how to overcome a school district’s FERPA objection, how to evaluate collectability before filing a spousal tort claim — write down the decision framework you used. Eighteen months in, that collection of frameworks is your firm’s actual intellectual property, and it’s what lets you bring on associates without losing quality.
Building in undeveloped territory is slower at first and faster later. The firms willing to operate without a map today are the ones setting the terms for their entire practice area tomorrow. If there’s a corner of the law your market is underserving, that’s not a warning sign — it’s an invitation.
