Do You Need a Person or a Function? Interim GC vs. a Fractional Legal Team

A founder called us a few weeks ago because her go-to counsel had just given notice and she had a financing set to close in six weeks. Her question was reasonable, and I thought it was aimed one layer too shallow.

“How fast can I find an interim GC?”

That’s not a dumb question. It’s just the wrong first one. Before you hire anyone to cover a gap, you have to know whether the thing you’re actually missing is a person or a function. Those aren’t the same problem, and they don’t have the same fix.

Here’s the short version, so you’re not hunting for it two thousand words from now. If the need is genuinely temporary, a vacancy, one big deal, a regulatory fire, then one senior lawyer stepping into the seat for a few months is the right tool. If the need is ongoing, even when it doesn’t yet justify a full-time hire, a team is the better structure, because one person has a ceiling, a calendar, and occasionally the flu. Most companies get this wrong by treating a structural need like a scheduling problem.

And the place they lose the most time isn’t the hiring. It’s the scoping. I’ll come back to that, because it’s where the weeks actually go.

Four options, not two

Most of the writing on this frames the decision as interim versus permanent, as if the only variable is timing. There are really four ways to cover legal leadership, and they solve different problems. Getting them confused is what costs companies money and momentum.

Outside counsel is what you’re probably using now. It’s good for discrete legal questions and bad at owning anything. A firm answers the question you bring them. It doesn’t tell you the question you forgot to ask, and it doesn’t sit in the room when the business decision gets made. At a certain point that gap stops being an inconvenience and starts being a risk.

An interim general counsel is a senior lawyer who steps into the seat full-time or close to it for a defined stretch, usually to cover a vacancy or run one big initiative like a financing round or a regulatory response. They report to the CEO or the board and typically hand off to a permanent hire when there is one. The value is speed and seniority: someone who can make senior calls immediately, without a six-month search first.

A fractional in-house legal department is the option people understand least, so let me be specific, because it’s the one the other articles skip. It is not a part-time solo lawyer. It’s a team. A senior lawyer, usually a former GC, leads the account and keeps the executive-level judgment, while attorneys, paralegals, and legal administrators handle the contract review, the filing deadlines, and the template work. You get the senior calls made by a senior person, and you stop paying senior rates for administrative tasks. The whole point of the structure is that the work doesn’t all sit on one desk, so no single person being out puts the company in a gap. It fits companies whose legal need is real and ongoing but doesn’t yet fill a full-time executive role, which describes most growing companies for a longer stretch than they expect.

A permanent GC is a full-time employee who builds and owns the function for the long haul, with authority to hire, set policy, and represent the company inside and out. That’s the right answer eventually, for most companies. It’s just rarely the right answer today, and hiring one in a hurry to solve a short-term gap is how you end up with an expensive mismatch you have to unwind in a year.

The trade-off that catches people off guard runs through all four: depth. A single lawyer, however senior, still has to personally review every contract, track every deadline, and manage every outside firm. There’s no bench. When that person is unavailable, the company has a gap, and the gap always seems to open during the week you could least afford it. Naming which of these four you actually need is most of the decision. The rest is execution.

Scope it before you call anyone

The single most useful thing you can do costs nothing and takes an afternoon: write down the trigger event and the expected end date before you post the role or call a recruiter. “Cover the GC vacancy until we hire permanently, target four months” gets you a different and better candidate than “we need legal help.” A two-week gap and a six-month engagement are not the same search, and the recruiters worth using will tell you so.

From there, a scoped brief prevents most of the friction that follows. Write down three things, in plain terms, before anyone starts.

The deliverables. Name the actual outputs. “Close this financing, run this investigation, cover contract review for four months,” not “ongoing legal support.” Vague briefs produce vague candidates, and later they produce vague accountability, which is worse.

The boundaries of authority. Can this person sign contracts? Hire and fire outside counsel? Speak to a regulator? Every one of those should have an answer before day one, not after the first time it comes up live.

The reporting line. Who do they report to, and who do they escalate to when something sits above their scope. If nobody’s answered that, the organization will answer it by accident, usually badly.

What to nail down in the contract

The contract is where scope creep either gets stopped or gets quietly built in. Before signing, get specific on the terms that actually govern the relationship:

• Scope of authority. What they can sign, approve, or represent without escalating.

• Hours and availability. A capped weekly hour count or a clear full-time commitment, stated explicitly, not implied.

• Fee model. Hourly, monthly retainer, or fixed project fee, with a clause for what happens when scope expands, because it will.

• Conflict disclosures. In writing, and updated if a new conflict surfaces mid-engagement.

• Termination terms. Notice period for either side, and what happens to work in progress if it ends early.

• Deliverables and reporting cadence. Specific outputs and a real schedule, not “ongoing support.”

• Handoff obligations. A written requirement to transfer files, contacts, and open matters to a successor. This clause reads like boilerplate right up until the week they leave, and then it’s the most important line in the document.

A couple of things make the engagement measurable instead of just billable. Set a few KPIs you’ll actually look at: contract turnaround time, open matters resolved per month, outside-counsel spend against budget, and whether the monthly report shows up on schedule. And require time transparency, whether that’s detailed invoices or a simple weekly summary of what got done.

The biggest red flag in the early conversations is a candidate or firm that resists putting hours, deliverables, or reporting in writing. That’s your answer. Vague terms upfront reliably produce vague accountability later, and by the time you notice, the engagement is half over.

Onboarding is the other place time leaks. Build the packet before day one: cap table, governance records, active contracts, pending litigation, the outside-counsel roster, and the five people they need to meet in week one, usually the finance lead, head of sales, board chair, existing outside counsel, and HR. Set up access on day one too, email, contract systems, e-signature, the data room if there’s diligence. Access delays quietly eat the first two weeks of a short engagement, and on a four-month clock two weeks is real money.

A 30/60/90 structure keeps the whole thing honest. In the first thirty days, inventory the open matters and flag anything urgent. By sixty, have contract review stabilized and a clear read on litigation exposure. By ninety, produce a written plan for either the permanent transition or continued coverage. Short measurable phases make progress visible and cut the handoff risk at the end.

What the person actually needs

Bar admission and a good resume are the floor, not the qualification. What separates an effective interim GC from a mediocre one is prior in-house experience, ideally as a GC, deputy GC, or senior legal director who has actually run a function rather than only advised one from the outside. Running a legal department and advising one are different jobs, and the difference shows up fast under pressure.

Look for someone who has managed outside counsel and can negotiate law firm fees, because that skill alone often pays for the engagement. Industry familiarity matters more than people expect. A lawyer who spent a career in healthcare regulatory work will ramp faster at a health tech company than a generalist, even a very sharp one, and ramp speed is most of what you’re buying in a short engagement. Comfort briefing a board and handling diligence questions under time pressure is another marker, because interim work often lands right on top of a fundraise or a sale, where that skill gets tested in week two.

Team management experience matters even when the role is nominally solo, because they’ll be coordinating paralegals, outside firms, and business stakeholders at the same time. A candidate who has only ever been an individual contributor inside a firm may struggle to run that coordination on a compressed timeline. And interview for judgment, not just credentials. Ask how they handled a messy vendor dispute or a board disagreement, not just what deals they closed. Ask for a time they told a CEO no. The ones who can’t name one either haven’t earned the seat or don’t remember using it, and neither is what you want. Get two references from people who worked under their leadership, not just alongside it.

What actually goes wrong

The most common failure point isn’t legal skill. It’s authority ambiguity.

If the board and the executive team haven’t made it clear that the interim GC speaks for the legal function, people route around them. They ask the CEO directly, or they default to whatever the departing GC used to say. The fix is a two-line internal announcement on day one that names the person’s authority out loud. It’s almost embarrassingly simple, and skipping it quietly breaks the engagement from the inside.

The second failure is the handoff that never happened. Departing GCs leave with a lot that never made it into a file, the informal side deal with a vendor, the verbal commitment, the dispute everyone agreed to stop discussing. An interim who doesn’t proactively interview the departing team and outside counsel in the first week can spend a month rediscovering problems that were already known to someone who’s now gone.

Timeline pressure creates a third. Interim engagements are temporary by definition, and some interims either rush decisions to show progress or freeze on calls they think belong to a permanent hire. Neither serves the company. The cure is the same written scope of authority from earlier: which decisions are theirs to make now, and which should wait.

And the last one is structural, not personal. A solo hire has no internal peer to sanity-check a hard call. That’s not a knock on the lawyer, it’s just what one desk means. It’s also the clearest argument for a team when the stakes are high, because the calls that most need a second set of eyes are exactly the ones a lone interim has to make alone.

Which companies actually need this

Technology and software companies are the frequent users, largely because growth-stage tech outgrows its legal function faster than its hiring plan accounts for. A company that just closed a Series B can suddenly need serious contract volume, IP protection, and privacy compliance handled by someone senior, with no time to run a six-month executive search. The legal need arrives before the org chart is ready for it.

Private equity portfolio companies are another strong fit. PE-backed businesses often need this kind of leadership during a hold, particularly around add-on acquisitions, and standing up dedicated coverage tends to make more sense than a portfolio company hiring its own permanent GC for what might be a three-year hold. The math and the timeline both point to fractional or interim rather than a full-time seat.

Healthcare and health tech lean on interim leadership during regulatory transitions, because compliance gaps in that sector carry real financial and reputational cost, and they carry it quickly. Nonprofits hit it too, usually around a governance overhaul or a major grant compliance requirement, where they need senior legal help for a defined stretch without the budget for a permanent hire. And any company mid-acquisition, on either side of the table, benefits from someone whose entire attention is on diligence rather than split between the deal and the day job. Diligence done in the cracks between everything else is how things get missed.

The real question

If your need is genuinely temporary, one competent interim lawyer is the right call. They stabilize the vacancy, run the project, hand off cleanly, and you’re done. That’s a good outcome, and I’d tell you to take it.

What a single person can’t solve is a structural need, because one person, however senior, has a ceiling on hours and attention. Companies that mistake “we found a great interim lawyer” for “our legal function is now stable” tend to find the gap the next time that lawyer is unavailable, which is reliably the worst possible moment for it to appear.

Most advice frames this as interim versus permanent, as if the whole thing turns on timing. It doesn’t. The more useful question is whether this company needs a person or a function. Diagnose that first. The timing question mostly answers itself once you have.

FAQ

Isn’t a fractional team more expensive than one interim lawyer? Usually it’s the opposite, once you account for who does what. With a solo hire you pay a senior rate for everything, including the contract review and deadline-tracking a paralegal should be doing. A team keeps the senior person on the senior work and moves the routine work to people suited to it, so your spend tracks the complexity of the work instead of the seniority of the one person doing all of it.

Can we start with an interim GC and convert to a fractional team or a permanent hire later? Yes, and that’s often the smart path. What makes conversion painless is documentation. If whoever’s covering you writes down processes and relationships as they go instead of scrambling in the final week, you can move from interim to fractional to full-time without rebuilding institutional knowledge each time. The painful handoffs are the ones nobody planned for.

We’re early and still rely on outside counsel. Is it too soon for any of this? Probably, and that’s fine. The marker isn’t revenue or headcount, it’s whether legal work is consistently landing on someone who shouldn’t be doing it, usually the CEO. When a founder is spending real weekly hours on contracts and legal questions instead of running the business, that’s the signal the need has turned ongoing. Until then, outside counsel is the right tool and you shouldn’t feel behind for using it.

If we bring in interim or fractional leadership, do we still need our outside law firms? Yes, and good internal leadership makes those firms cheaper, not redundant. Part of the job is managing outside counsel, scoping the work tightly, and pushing back on the bill. You keep the firms for specialized and litigation work. You gain someone internal who makes sure you’re not overpaying for it.

Who owns the files and open matters when the engagement ends? You do, and your contract should say so plainly. Require, in writing, that all work product, files, contacts, and open-matter status transfer to the company or the successor at the end of the engagement. This is the clause people treat as boilerplate and then regret, because the alternative is reconstructing your own legal history after the person who held it in their head is already gone.
