Costs assessor rules & contract remedies
Primary provisions and procedural rules for solicitor–client fees. Two different pathways: an assessor determines fair and reasonable legal costs; contract, equity and consumer-law claims can seek court remedies based on misleading conduct or breach. Their legal tests differ.
What a WA taxing officer must decide
Determine whether an agreement is valid and whether legal fees are fair and reasonable; examine disclosure and reasonableness of work/rates. The mere existence of a contractual hourly rate is not conclusive.
WA Uniform Law (official)Written reasons; mandatory regulator referral where charges or issues may indicate professional misconduct; assessment findings are admissible in disciplinary matters.
WA Uniform Law (official)Normally the practice pays assessment costs where required disclosure failed or bills are reduced 15% or more; express fairness exception applies.
WA Uniform Law (official)Functions, certificates, review, enforceability and recovery of fees paid above assessment. Review under s 149 is usually within 28 days.
WA Application Act (official)The Legal Practice Board may request a costs assessment during an investigation under Uniform Law s 284. An investigation-initiated assessment is generally conducted as if requested by a client.
Current WA regulations (official)A disclosure failure can avoid s 178 consequences only if the cumulative conditions are met, including timely rectification within 14 days of awareness and lack of material effect on client choice.
WA Legal Practice Board guidanceRepayment and enforcement powers
| Provision | Effect and limit |
|---|---|
| Uniform Law s 290 | Consumer complaint determination may include waiving or reducing fees or compensation (subject to jurisdictional prerequisites). |
| Uniform Law ss 291–293 | Costs dispute threshold and restriction on binding regulatory decisions for larger unresolved disputes; do not equate a conduct complaint with a large bill dispute. |
| Uniform Law ss 308(3), 309 | Compensation orders may prohibit fee recovery or require whole/partial fee repayment; proof of loss and interests of justice generally needed unless agreement. |
| Uniform Law s 310 | Regulator compensation order can be filed in court for enforcement. |
| WA Application Act s 151 | Recovery as a debt of paid costs above a completed assessment; not a pre-assessment automatic refund. |
Existing proceedings: The WA Legal Practice Board says it generally cannot help with matters already before a court. Costs complaints also have strict time limits. The refund power is not an automatic alternative to an existing court proceeding. Board limitations · Board costs complaint timeframes
s 308(2)'s ordinary monetary compensation limit is $25,000 in the WA Uniform Law; fee repayment under s 308(3) is differently worded and contains no express dollar cap. No route is automatic; complaint jurisdiction and proof matter.
The NSW assessment scheme and its distinct regulations
NSW Legal Profession Uniform Law Application Regulation 2025, Part 5 (ss 27 onwards) governs costs-assessment applications, fees, documents, responses and referral. Section 29 expressly requires applicant authority for the assessor to inspect documents held by the law practice. NSW Supreme Court states its assessors decide applications on the papers, are not officers of the Court when assessing, and do not apply ordinary civil procedure rules to administering the scheme.

Contract, misrepresentation and restitution
Misleading conduct: ACL s 18 and WA Fair Trading Act s 19; ACL ss 236–237 and 243 provide damages and potential orders including setting aside or varying contracts and repayment. Proof of misleading conduct, causation and appropriate relief remains necessary. A non-binding estimate is not necessarily immune if important known expenses are omitted.
Fiduciary rescission: in the presence of an undisclosed solicitor–client conflict, equity may support rescission, subject to restoration. This is a distinct cause of action from deficient statutory costs disclosure.
