Legal Costs Disputes & Billing Resolutions

Whether you’re a client challenging fees or a law firm defending them, Windsor Law provides expert advice to resolve costs disputes quickly and fairly.

Disputes over legal costs are stressful, especially when they arise after lengthy or expensive legal matters. Unclear fee agreements, unexpected invoices or poor communication can all lead to tension between lawyers and clients.

At Windsor Law, we specialise in resolving costs disputes through clear advice, negotiation, and formal assessment processes. We represent both clients and law firms, ensuring fairness, compliance and transparency under the Legal Profession Uniform Law (NSW) and related regulations.

What We Cover

Our team advises on a wide range of legal costs and billing issues, including:

  • Overcharging & Unreasonable Bills – assessing if fees charged were fair for the work performed. (lawaccess.nsw.gov.au)
  • Disputes Between Clients & Lawyers – handling negotiation, settlement and cost assessments.
  • Formal Costs Assessment Applications – lodging or responding to assessments with the Supreme Court Costs Assessment Scheme. (costsassess.nsw.gov.au)
  • Itemised Bills & Fee Disclosure – ensuring lawyers comply with disclosure rules and clients receive transparent invoices. (legalaid.nsw.gov.au)
  • Security for Costs & Inter-Parties Costs Orders – assisting businesses and litigants to recover or challenge court-awarded costs. (nsw.gov.au)
  • Professional Negligence Linked to Overcharging – pursuing damages where overbilling caused loss or breach of duty.

We also advise on ethical compliance for lawyers and law firms to avoid future disputes through clear fee agreements and proper disclosure practices.

Your Rights & Time Limits
Under the Legal Profession Uniform Law (NSW):
  • Clients are entitled to a costs disclosure before engaging a lawyer.
  • You have the right to request an itemised bill within 30 days of receiving a lump sum invoice. (lawaccess.nsw.gov.au)
