Definition
A special retainer is an engagement of an attorney or other legal counsel for a specific, defined purpose — most commonly, to handle a particular case, transaction, or legal matter. The attorney's authority and obligation extend only to that designated matter; upon its conclusion, the engagement ends. This distinguishes it from a general retainer, by which a client secures a lawyer's availability or ongoing services across a range of matters over time.
Common Language
Modern common usage (Wiktionary): A fee paid to counsel for work on a particular case.
Historical common usage (Webster's 1913): No entry found for "special retainer" as a compound term.
The common usage captures one dimension accurately — a special retainer does involve payment — but reduces the concept to a fee rather than a relationship. The legal significance lies not in the payment alone but in the scope of the engagement it creates: an attorney hired under a special retainer owes duties only within the defined matter, and the question of whether those duties attached (and when) has real consequences for conflict-of-interest analysis, privilege, and malpractice exposure.
Common Confusion
SPECIAL RETAINER vs. GENERAL RETAINER: These are the foundational distinction in retainer law. A general retainer secures the lawyer's availability or loyalty — often for a period of time or across recurring matters — whether or not specific work is assigned. A special retainer is tied to a particular task. Historically, courts and treatises used these terms with precision; modern practice sometimes blurs them by calling any upfront payment a "retainer," which can create ambiguity when scope of representation is disputed.
SPECIAL RETAINER vs. RETAINING FEE: A retaining fee (sometimes called a "classic" retainer) is paid simply to keep an attorney available and is earned upon receipt regardless of work performed. A special retainer fee is typically applied against fees for the specific matter. Conflating the two has practical consequences: a true retaining fee is generally non-refundable, while advance fees held against a special matter may be subject to refund of unearned portions under professional conduct rules.
Why It Matters in Research
The primary research value of this term is definitional and relational: understanding what a special retainer is requires anchoring it against its counterpart, the general retainer. Sources that address only one without the other are incomplete for research purposes.
In historical legal materials, "special retainer" appears frequently in attorney-client relationship cases and professional responsibility treatises. Researchers examining 19th- and early 20th-century case law will encounter the term as a technical distinction with jurisdictional bite — courts sometimes held that duties of confidentiality or conflict avoidance differed depending on whether the attorney had been specially or generally retained. This distinction has not disappeared, but modern professional conduct codes (particularly post-Model Rules) tend to analyze scope of representation directly rather than through the retainer classification.
A trap in historical sources: some older courts used "special retainer" loosely to describe any paid engagement, without intending the specific/general contrast. Context matters. Check whether the court is actually using the term technically or colloquially before drawing doctrinal conclusions.
For corpus researchers, the term appears most productively in: (1) professional responsibility materials, (2) attorney fee disputes and quantum meruit cases, and (3) disqualification motions, where the scope of a prior engagement determines whether a conflict of interest exists.
Historical Dictionary Support
Black's Law Dictionary defines a special retainer as "an engagement or retainer of an attorney or solicitor for a special and designated purpose; as, to prepare and try a particular case." This definition is stable across editions and accurately captures the core meaning. It is, however, brief to the point of being skeletal — it does not address the fee dimensions, the duration of the relationship, or the duties that attach.
Historical dictionaries generally treat the special/general retainer distinction as binary and well-settled, which it was as a formal matter. What the dictionaries understate is the doctrinal work the distinction was asked to do: courts in fee disputes, malpractice actions, and conflict cases often had to reconstruct what kind of retainer existed from the conduct of the parties, since written retainer agreements were historically uncommon. The dictionary definition assumes a clarity that practice did not always supply.
Jurisdictional Note
Modern professional conduct rules — including the ABA Model Rules of Professional Conduct — do not use the term "special retainer" as a formal category, instead addressing scope of representation directly under Rule 1.2. State bar ethics opinions vary in how they treat advance fee arrangements. Researchers working in any specific jurisdiction should consult that jurisdiction's professional conduct rules and ethics opinions rather than relying on the common law retainer taxonomy alone.
