Fractional in-house counsel or fractional GC: which does your team need?

Choose a fractional general counsel when you need someone to own the legal function: set priorities, advise the executive team and board, and decide how work is split with outside counsel. Choose fractional in-house counsel when you already have that leadership and need an experienced lawyer to take on a defined body of work under it. If you have neither a GC nor spare capacity, you may need the leadership role first and the hands-on role later.

Seniority matters in both roles. The distinction is the mandate, including who sets priorities and who is accountable for the legal function.

What each role is for

A fractional GC is defined by mandate. They carry the responsibilities of a head of legal on a part-time basis: advising founders or executives, preparing for board conversations, shaping the operating model, managing outside counsel, and stepping in on hands-on work where the function needs it. Our fractional general counsel service gives companies senior legal leadership before a permanent GC is justified.

Fractional in-house counsel is defined by embedding. The lawyer works inside your team, in your tools, with your stakeholders, usually on execution: commercial contracts, employment questions, compliance projects, deal support. They typically report to an existing legal leader or to a business executive who holds the legal relationship. Our Fractional InHouse service follows this model.

Many teams need some of each at different points, which is why it helps to separate the two ideas before you write a brief.

A four-question test

When the label is unclear, ask these questions about the work rather than the title.

1. Who sets legal priorities today? If nobody does, and the business is deciding by whoever shouts loudest, you have a leadership gap.
2. Who answers questions from the board or the CEO about legal risk? If that person is missing or overstretched, the role needs executive judgment.
3. Who decides what goes to outside counsel, and who manages those firms? If it is unowned, a leader is needed. If it is owned but the volume is too high, you need capacity.
4. Is the work mostly defined and repeatable, or mostly ambiguous and strategic? A defined delivery gap points toward added capacity. Responsibility for setting direction points toward legal leadership; either role can involve complex judgment.

Use the answers to write the mandate. If they point in different directions, separate the leadership responsibilities from the delivery workload before deciding how to staff them.

When fractional in-house counsel fits

This is the better fit when there is already a head of legal, or a business owner who sets direction, and the problem is volume or specialism. Typical cases include a contract queue the team cannot clear, a project that needs experienced hands for several months, an area such as employment or privacy where you want depth without a hire, or cover for a gap in a small team.

The lawyer works within the agreed strategy and needs room to make judgment calls within defined limits. That means setting out up front what they can decide, what they raise with you, and what escalates.

When a fractional GC fits

This is the better fit when the legal function lacks an owner. A founder or executive may be quietly acting as the legal lead, or a general counsel may have left and the team has no one setting direction. It also fits when the business is approaching a moment that needs senior judgment, such as a financing, a first set of board materials, or a redesign of how legal requests come in.

The mandate matters more than the hours. Define whether the person is expected to run meetings with the executive team, own the outside counsel relationship, build policies and templates, and report on legal risk, or whether they are only there to answer questions. If the person is also expected to do hands-on drafting, say so, because it changes how many hours you need and which candidates are credible.

Titles can mislead

Buyers and providers both use "fractional GC" loosely. A role described that way may in practice be mostly hands-on transactional work, with the lawyer applying the team's known positions and pushing back where it matters. That can be exactly right, but it is a different job from owning the function. Read the scope, not the label.

The reverse also happens. A role titled as in-house counsel may quietly include setting up the legal function from scratch. If so, the work is closer to a GC mandate and the candidate should be assessed that way.

Specialism cuts across both. A strong generalist is not automatically a match for a role that leans on a specific field, and trade-offs that look small on paper can mean a long ramp in practice. Decide early which one or two areas cannot be left to learning on the job, and screen against them.

Moving from one to the other

The arrangement can change as the team’s needs change. A fractional GC may stand up processes and then hand day-to-day work to a fractional in-house lawyer. A fractional in-house lawyer who proves valuable may take on more scope, or the team may decide to hire permanently. Discuss these possibilities at the start and confirm how the terms handle a change in scope.

If a permanent hire is on the table, ask about the terms before you need them. Our permanent-hire conversion fee decreases with time in the engagement. Confirm the applicable terms for the arrangement you are considering. Whatever provider you use, get the equivalent terms in writing.

Decision checklist

1. What is the biggest gap: leadership, capacity, or specialism?
2. Who will the lawyer report to, and who sets their priorities?
3. Which decisions can they make alone, and which come back to you?
4. Is outside counsel management part of the role?
5. Is the work mainly execution, mainly advice, or both?
6. Which one or two experience areas are non-negotiable?
7. How will you review the scope after the first few weeks?
8. What happens if the need grows, shrinks, or becomes permanent?

Fractional GC or a law-firm retainer

A law-firm retainer can be sufficient when the business has an internal owner of legal priorities and needs defined advice or access to specialist resources. A fractional GC is relevant when the gap is recurring leadership: prioritizing work, participating in executive decisions, coordinating advisers and owning the legal operating plan. Neither label guarantees a particular level of access. Compare included work, decision ownership, response expectations, specialist depth, fees and exclusions. Some companies use a fractional GC and a firm retainer together.

What the existing GC retains

When adding fractional in-house counsel, the existing GC normally remains accountable for legal strategy, competing priorities, executive communication and the escalation framework. Define which risk exceptions and specialist or outside-counsel decisions remain with the GC. Delegate specific workstreams and decision limits explicitly; do not rely on a title to determine authority. A lawyer can own the commercial queue without becoming accountable for the entire legal function.
