KembaraXtra - Legal Terms - Solicitor and Own Client Basis of Costs

The solicitor and own client basis of costs is a method of assessing legal costs that determines the amount a privately represented client must pay to his or her own solicitor for legal services provided. Unlike costs assessed between opposing parties after litigation, this basis concerns the contractual relationship between solicitor and client. It aims to ensure that the solicitor receives reasonable remuneration for work properly undertaken while protecting the client from excessive or unnecessary charges. The assessment is therefore broader than ordinary party-and-party costs because it recognizes that clients often instruct solicitors to perform work that may not be recoverable from an opposing litigant.

Under this basis of assessment, the court or costs assessor allows all costs that are reasonably incurred and reasonable in amount. The solicitor must demonstrate that the work performed was necessary or appropriate for advancing the client’s interests and that the charges reflect a reasonable level of remuneration for the services provided. Time spent, complexity of the matter, urgency, responsibility assumed, specialist expertise, and the value or importance of the dispute may all be considered in determining whether the fees claimed are reasonable. Costs that are excessive, duplicative, or unnecessarily incurred may nevertheless be reduced or disallowed.

The solicitor and own client basis differs significantly from the standard basis or indemnity basis used when one litigant seeks to recover costs from another. Party-and-party assessments generally exclude work undertaken solely for the client’s private benefit or matters unnecessary for the litigation itself. By contrast, solicitor and own client assessments permit recovery of a wider range of work because the solicitor’s contractual duties extend beyond what may ultimately be recoverable from an opponent. Consequently, even where a successful litigant recovers legal costs from the losing party, the client may still remain liable for part of the solicitor’s bill under the retainer agreement.

The contractual relationship between solicitor and client is governed by both general contract law and professional regulation. Solicitors are required to provide clear information regarding likely costs, charging methods, and any significant changes in anticipated fees. Bills delivered to clients may, where appropriate, be challenged through formal assessment procedures if the client believes the charges are unreasonable. Courts therefore supervise solicitor-client costs to ensure fairness while recognizing that solicitors are entitled to proper remuneration for professional services competently performed.

Modern legal practice frequently employs alternative charging arrangements such as fixed fees, conditional fee agreements, damages-based agreements, or retainers specifying hourly rates. Regardless of the charging method adopted, the underlying principle remains that the solicitor may recover only costs that are reasonable and properly incurred. Professional conduct rules reinforce this obligation by requiring solicitors to provide transparent pricing information and to avoid charging clients unfairly or without proper justification.

The solicitor and own client basis of costs therefore provides the legal framework for determining what a client owes his or her own solicitor under the professional retainer. It balances the solicitor’s right to fair payment against the client’s right to protection from excessive legal fees through judicial supervision and professional regulation. The system promotes confidence in legal services by ensuring that legal costs remain both transparent and objectively reasonable.
