Matter Budgets Clients Actually Accept

Fee disputes are usually not disputes about value. They are disputes about expectation: the client formed a view of the likely cost early, nobody revised it as the matter developed, and the final invoice arrived as news. The budget's job is to prevent that specific failure.

Budget by phase, not by total

A single number for a whole matter is either padded enough to be unattractive or optimistic enough to be exceeded. Phases give the client a series of smaller, better-informed decisions.

• Investigation and advice — scope known, estimate reliable.

• Pre-action correspondence and negotiation.

• Proceedings issued through to disclosure.

• Expert evidence, if required.

• Trial preparation and hearing.

Each phase carries its own estimate and its own assumptions. Later phases can be indicative, clearly labelled as such, and firmed up when the preceding phase completes and the facts are better known.

State the assumptions in writing

Most overruns are assumption failures rather than estimation failures. Write the assumptions down where the client will read them: the volume of documents, the number of witnesses, that the other side engages constructively, that no additional party joins. When one breaks, you have a specific, agreed reason for a variation rather than a general request for more money.

An overrun with a named broken assumption is a variation. An overrun without one is a dispute.

Set a notification trigger

Agree at the outset that the client will be told when recorded time reaches a set proportion of a phase estimate — 70% is a workable default. The conversation at 70% is about choices: narrow the scope, accept an increase, or change approach. The conversation at 110% is about blame.

Make it operational, not aspirational

A budget that lives in the engagement letter and is never compared to actuals is decoration. The phase codes have to exist in the time recording system, and someone has to look weekly. Where the practice management system supports a threshold alert, use it — the manual version depends on remembering during a busy week, which is exactly when it fails.

Report against it unprompted

Sending a short position statement with each invoice — spend to date by phase, remaining estimate, any variation and why — costs a few minutes and changes the relationship. Clients who receive it stop asking for it, and the small corrections happen along the way instead of accumulating into one difficult conversation at the end.

Costs rules, budgeting obligations in litigation and requirements for costs information to clients vary by jurisdiction; treat this as commercial practice and check it against the rules and any court-mandated budgeting regime that applies to you.
