The Bench Grows: Recalibrating an External Advisory Relationship After a First In-House Appointment

An external adviser usually learns the news in a short email: the client has appointed its first in-house lawyer, or perhaps a finance lead with a mandate to bring more work inside the business. The temptation is to reply warmly and carry on. That is a mistake. The appointment is not simply a new name on the distribution list. It is a change in the client's governance, and the external relationship needs to be recalibrated while the change is still fresh.

The risk is not that the work disappears overnight. It is that two advisers begin answering the same question, the client receives two slightly different versions of the same advice, and the external firm spends unbilled time defending a position it was never asked to take. A clean handshake in the first thirty days prevents that drift.

Why the first in-house appointment changes the weather

A first in-house appointment is usually a sign of maturity. The client has decided that some decisions should be made closer to the business, with someone who knows the operating rhythm and can hold the paper internally. For the external adviser, that should be welcome news. It can mean better instructions, faster approvals and a more sophisticated buyer of specialist support.

But it also changes the external adviser from default source of answers to one supplier among several. That shift is easier to manage if it is named early. The worst outcome is an unspoken rivalry: the in-house team believes the external firm is clinging to work, while the external firm believes it is being excluded without explanation. Both sides then over-communicate defensively, and the client pays for the confusion.

The correct response is neither to retreat nor to campaign for more work. It is to establish, in writing, how the relationship will operate now that a new gatekeeper sits inside the client.

Days one to ten: Confirm who decides what

Begin with a short conversation with the new appointment, not a lengthy pitch. Ask what they have been asked to take responsibility for, what remains with the board or the executive team, and where they expect external support to continue. Then convert the answers into a decision-rights map.

A useful map is one page, with four columns: the matter or decision; who instructs externally; who approves the external advice; and who holds the final internal decision. Add a fifth column for anything the client wants to keep entirely in-house. The map should cover routine matters, urgent matters and matters that are sensitive because they involve the board, a regulator or a dispute.

The map is not a contract. It is a working instrument that exposes assumptions before they harden. If the new in-house lead expects to approve every external letter, the external firm needs to know that before a partner sends one. If the finance lead expects to sign off fees above a threshold, that should be visible to everyone who instructs work.

At the same time, update the engagement letter. The addendum need not be elaborate. It should confirm the instructing contact, the approval route for new work, the scope assumptions, the fee authority, the confidentiality arrangements and the client's expectations around data protection and document retention. If the client now has an internal legal or finance function, the addendum should also record who may give instructions in an emergency and who may vary scope.

Days eleven to twenty: Rewrite the operating rhythm

Communication is where new gatekeepers and external advisers most often collide. The client may want everything routed through the new in-house lead; the business may still be used to calling the external partner directly. Both habits can survive for a while, but not indefinitely.

Agree a channel charter. It should say who is copied on what, which matters require a call rather than an email, how quickly urgent instructions will be acknowledged, and whether the client prefers its own systems for document sharing. It should also address the awkward question of direct contact with the business. If the new in-house lead wants to be the sole channel, the external firm should respect that, but it should also agree an exception for urgent operational matters.

This is also the moment to create a duplication register. List the tasks that have moved inside, the tasks that remain outside and the tasks that are genuinely shared. Shared tasks are the most dangerous. A contract review that both sides assume the other is doing is not collaboration; it is a gap. The register should be short, reviewed at the next monthly meeting and updated when responsibilities move.

Days twenty-one to thirty: Settle the paper and the handshake

By the end of the month, the relationship should have three artefacts: an updated engagement addendum, a decision-rights map and a file custody schedule. The third is often overlooked. A new in-house function will want to know where the matter file sits, who holds originals, how long records are kept and how documents are returned or transferred if the relationship changes.

File custody is not a bureaucratic detail. It affects privilege, regulatory requests and the client's ability to change advisers without disruption. The schedule should identify the client's retained records, the external firm's working papers and any third-party material. It should also confirm the client's rights over the file and the firm's retention obligations.

Close the thirty days with a short review meeting. Do not use it to sell additional services. Use it to confirm that the map still reflects reality, that the channel charter is being followed and that no work has fallen between the two teams. Record the conclusions in a brief note and send it to the client. That note is the handshake.

The cost of skipping the reset

The commercial argument for this discipline is straightforward. A recalibrated relationship produces fewer duplicate reviews, fewer surprised invoices and fewer conversations in which the external adviser discovers, too late, that a decision was taken elsewhere. It also protects the client from the quieter cost of confusion: advice that is technically correct but operationally irrelevant because it was framed for the wrong decision-maker.

A first in-house appointment should not be treated as a threat to be managed. It is a change of seating arrangement. The external adviser who accepts the new map early, and puts it in writing, is more likely to be retained for the work that genuinely needs specialist judgement. The one who pretends nothing has changed is more likely to be slowly excluded from decisions that once came automatically.
