Every client is entitled to a clear account of how legal costs arise before proceedings begin, and section 150 of the Legal Services Regulation Act 2015 requires solicitors to provide written notice of costs, or the basis on which they will be calculated, at the outset and as the case develops. What that notice cannot tell you is the single largest determinant of the final figure: how the case is fought.
What actually drives cost
Contested family litigation is priced by its battlefronts. Each disputed valuation means duelling experts. Incomplete disclosure means discovery motions. Every interim application is a hearing with preparation behind it. High-conflict children's disputes add reports and review dates. A case with three live fronts costs a multiple of a case with one, and a High Court case costs a multiple of the same dispute on Circuit. The most expensive sentence in family law is on principle.
What controls it
Cost discipline is mostly decision discipline: full early disclosure that removes the other side's grounds for motions, agreed single valuers where possible, honest early assessment of the realistic range of outcomes, and settlement engagement at the moments when information is complete, typically after affidavits are vouched and valuations exchanged. In the general jurisdiction costs follow the event, but in family proceedings each party commonly bears their own costs, and conduct of the litigation, including unreasonable refusal to engage, can influence costs orders. Funds spent on the contest come out of the same pool the court is trying to divide.
In contentious business a solicitor may not calculate fees as a percentage or proportion of any award or settlement, and clients should be wary of anyone suggesting otherwise. Clear scope, staged budgets tied to the phases of the case, and honest review at each phase remain the professional standard this practice works to.
