At some point in a company's growth, the question lands on the management agenda: should we hire our own lawyer? It rarely arrives in the abstract. It arrives as a contract backlog the sales team complains about, a legal bill that made the CFO look twice, or a financing round where nobody inside the company could hold the pen. The instinct is to treat it as a yes-or-no decision. It is more useful to treat it as a sorting exercise: which legal work belongs inside the company, and which never will.
Three tests: volume, recurrence, strategic weight
Volume is the obvious test, but the crudest. Annual external spend is a starting point, yet a single dispute or acquisition can dominate a year's bill without saying anything about the baseline. The better question: is there enough legal work, week after week, to occupy a good generalist, not in a peak month, but in an ordinary one?
Recurrence matters more. If the work is the same in kind (sales contracts, procurement terms, NDAs, employment questions, the occasional data-protection query) it rewards someone who learns the business once and applies that knowledge daily. If instead it is a sequence of one-offs in different fields, an in-house generalist will spend their time briefing external specialists anyway.
Strategic weight is the test most often missed. Where legal judgment shapes decisions (market entry, pricing models, partnerships, the relationship with a regulator) you want that judgment in the room early, not in a memo afterwards. A company negotiating its future in regulated territory needs a legal voice at the table; a company with heavy but routine contract flow may not.
If two of the three tests point inside, a first hire usually makes sense. If only volume does, a structured external setup is often the better answer.
What a first in-house counsel does well
The first hire's real product is context. Someone who knows the product, the deal flow and the company's actual risk appetite can turn a review that took a week externally into a same-day answer, because they are not reconstructing the business each time.
Just as important is triage: knowing which contracts deserve negotiation and which can be signed as they are, which complaint is noise and which is the start of a dispute. Add playbooks, templates and an orderly contract archive: institutional memory that belongs to the company. And a good in-house counsel becomes an intelligent buyer of external work: defining scope precisely, comparing offers, refusing open-ended mandates.
What stays external anyway
Three categories of work do not move in-house, however good the hire.
