Changing the Terms Halfway Through
Rates rise, scope grows, teams change and matters outlive their letters. Four changes, and what each needs in order to be agreed rather than imposed.

Four things change during a long matter: the rates, the scope, the team and the arrangement itself. Each needs a different act to become agreed, and each produces a particular dispute when it is not.
The commercial boundary in “Changing the Terms Halfway Through” becomes more useful when estimated work, recorded hours and authorised scope can be compared without changing the signed terms. Teams researching how employee monitoring works can use review the official product overview to organise that operational evidence while keeping the engagement letter and approved change record as the contractual source of truth.
A change that appears first in a bill has not been agreed, whatever the engagement letter permits.

Changing the rates
Usually permitted on notice. The notice is the whole of the obligation and it is the part most often skipped.
- The rates — notice, in writing, before the period they apply to.
- The scope — an email at the time, with a rough price.
- The team — a name and a grade when it happens.
- The arrangement — a letter, because it changes every later bill.
An email in November about January rates costs nothing. The same rise discovered in a February bill costs a conversation and some goodwill.
What the notice should say
The new rates, the date they apply from, and which matters they affect — including whether work in progress moves to the new rate.
That last question is the one clients ask, and leaving it unanswered produces a query on every bill until it is.
Changing the scope
An email, at the time, saying the work is additional and roughly what it will cost. It is described in its own note here.
The important property is timing: the same email after the work is done is a request to be paid, not an agreement to proceed.
Changing the team
A name and a grade, sent when it happens. Where the new person is more senior, say why.
Nobody objects to a change announced; most people object to one discovered.
Changing the arrangement
From hourly to fixed, from capped to uncapped, from matter-by-matter to retainer. The largest change and the one most often done by conversation alone.
It needs a letter, because it alters every subsequent bill, and because the people who agreed it will both have left within three years.
The matter that outlived its letter
Engaged for a two-week piece of advice, still running eighteen months later with four workstreams.
Technically the original letter governs. Practically nobody believes it does, and neither side could say what the terms now are.
The annual review
One page, once a year, on continuing matters: current scope, current rates, current team, current arrangement.
It takes twenty minutes and it is the only reliable way a long relationship keeps a document that matches reality.
Changes the client asks for
A new reporting format, a different billing cycle, a requirement that bills carry codes.
These cost the firm real time and are almost always absorbed. Where they are substantial, they are a change of terms too.
Agreeing in an email
Entirely sufficient for most of these, and better than nothing by a wide margin. "Confirming what we discussed: from 1 March the rates will be X, and the Brighton workstream is additional at an estimated Y."
Two sentences, one record, no negotiation.
The record of changes
A single file per matter listing every change with its date. Four lines after two years.
It is what the firm reaches for when a bill is challenged, and the absence of it is why many challenges succeed.
What not to do
Put the change in the bill and wait to see whether anybody notices. It frequently works and it is the mechanism by which relationships quietly deteriorate.
Clients who notice later treat everything else on the bill with suspicion.
The change that is never written down
A gradual drift in what the firm does: a new workstream absorbed, a reporting obligation accepted, a standing call added.
No single step is worth a letter and the cumulative effect is a different engagement at the same price.
The annual review is the only thing that catches it, because it asks what the arrangement currently is rather than what changed this month.
Who notices the drift
Usually the person doing the work, who has no standing to raise it, and the billing team, who see the hours and have no context.
Giving either of them a route to flag it — one line, to the matter partner, monthly — costs nothing and is the only early warning available.
Changes the firm makes to itself
A merger, a new billing system, a different reporting format, a changed cycle.
These are the firm's business and they reach the client as unexplained differences on a document. A sentence before the first changed bill prevents a query that is otherwise certain.
The letter nobody wants to send
A rate rise in a difficult year, to a client who has already challenged two bills.
It is still better sent than absorbed into the figures quietly, because the alternative is a permanent undisclosed discount that nobody ever revisits.
The standing rule
Nothing that changes what a client pays appears first in a bill. Every such change is raised in its own message, in advance, in two sentences.
It is one sentence of policy and it removes an entire class of dispute.
