Can you mark up a contract attorney's time? Billing rules for outsourced lawyers
The ethics of billing clients for contract lawyer time: what ABA Formal Op.
08-451, Model Rule 1.5(e) and one Illinois advisory opinion establish — and the markup number no source on record supplies.
A law firm can bill clients for contract attorney work, and the ethics opinions on record permit the outsourcing itself under conditions: an Illinois State Bar Association advisory opinion treats it as permissible when it contributes to competent representation, with reasonable confidentiality and conflict measures and client disclosure ordinarily required.
What you may charge the client on top of the contract lawyer's rate is a fee question: this page covers the disclosure rule, Model Rule 1.5(e) on dividing a fee between firms, and the supervision duties that follow the work.
What does ABA Formal Op. 08-451 say about markups?
Start with what is actually on record, because it is less than the citation suggests.
ABA Formal Opinion 08-451, dated August 5, 2008, is the American Bar Association's opinion on outsourcing legal or nonlegal support services.
The ABA distributes the original as a paid download, which this research did not obtain; everything this page says about the opinion comes through a second document — Illinois State Bar Association Opinion 19-04, which quotes and discusses it.
So the page describes 08-451 only as the ISBA records it, and quotes none of its text.
The conclusion the ISBA records is about responsibility, not pricing: 08-451 concluded that a lawyer may outsource legal or nonlegal support services to other lawyers or nonlawyers outside the firm, provided the lawyer remained ultimately responsible for those services under Model Rules 5.1 and 5.3.
Notice what is missing from that conclusion.
Nothing our research could verify says the opinion sets a markup percentage, endorses one, or forbids one — the markup question, meaning what a firm may charge a client over and above what it pays an outside lawyer, is not answered by anything on this page's record.
An article that quotes 08-451 directly on markups is quoting an authority we could not read.
The model-rule text has moved since 2008, and again the account is the ISBA's: the ABA's 2012 amendments to the Model Rules added outsourcing guidance to the comments to Rules 1.1 and 5.3, and did not adopt 08-451's standard of treating outsourced lawyers and nonlawyers as if directly affiliated with the firm.
The comments to the model rules carry the outsourcing guidance; the affiliation framing did not become model text.
Two standing caveats before the rest of the page.
An ABA formal opinion interprets the model rules — it is not itself the rule in your state, and it binds no state; the version your state adopted controls.
And outsourcing as a decision — which tasks travel well, the vendor diligence, the supervision file — is its own topic, covered in our guide to outsourcing legal work.
Cost vs fee: when the markup is allowed
Contract lawyer time can reach a client's invoice through two doors: as a cost the firm passes through at what it pays, or as part of the fee the firm charges for legal services.
The distinction matters because the rules this page cites attach to a fee: reasonableness and fee-division standards are written about fees, which is why the lane an invoice sits in is the first thing to identify.
The question has an ABA address.
ISBA Opinion 19-04 cites two earlier ABA formal opinions that bear on the question — Formal Opinion 88-356 on temporary lawyers, and Formal Opinion 00-420 on billing contract lawyers' costs.
Our research did not read either opinion, so this page will not tell you what they conclude; a title is not a holding.
If your firm is pricing contract lawyer time, those two opinions are the ABA documents this record points to on the question, and your state bar's ethics counsel can tell you how your state treats them.
What no source on record supplies is a number.
Our research found no source establishing a standard markup or origination-credit percentage for contract lawyer time — the split is set firm by firm, not by a rule of thumb.
The rules this page cites supply conditions, not percentages.
The engagement structure decides which rules reach the invoice.
A contract attorney engaged as a separate practice raises the fee-division question taken up below; a lawyer working inside your firm is a different structure with a different frame.
How to structure and staff the engagement in the first place is the hub's topic — our guide to hiring contract attorneys covers levels, screening and onboarding — and what the market pays is a separate question from what you may bill, covered in our guide to contract attorney rates.
Do you have to tell the client?
The clearest rule on this page's record is an Illinois one.
ISBA Opinion 19-04, an October 2019 advisory opinion from the Illinois State Bar Association, states: "Disclosure to, and informed consent by, the client will ordinarily be required."
Informed consent, the same opinion says, is "always required if the lawyer delegates or transfers complete or substantial responsibility for a matter to an unaffiliated lawyer" — and a matter handed to a contract attorney who is not part of your firm is that scenario whenever what moves is complete or substantial responsibility for it.
Scope that carefully.
It is one state bar association's advisory reading of the rules — persuasive reasoning rather than a statute, and Illinois's rather than yours.
The rules your state adopted control, and another state's bar may read them differently.
What the opinion establishes is the default posture: a client whose work is moving outside the firm is ordinarily told and asked.
What our research does not establish is the content of that disclosure.
Nothing on record specifies whether a firm must tell the client what it pays the contract lawyer, or how an invoice must present the difference between that and the amount billed; nothing on record fixes the timing of the conversation either.
Those are exactly the details to settle with your state bar's ethics counsel while you are designing the arrangement — not after the first invoice has gone out.
Fee-division rules (Rule 1.5(e)) when the contract lawyer is not an employee
When the contract attorney practices through a firm of their own rather than working as part of yours, the fee question can change shape: you may no longer be one firm pricing its own services, but two firms dividing one fee — whether paying the contract lawyer counts as a division is not settled by anything our research verified.
ABA Model Rule 1.5(e) allows a division of a fee between lawyers who are not in the same firm only if the division is proportional to the services each lawyer performed, or each lawyer assumes joint responsibility for the representation; the client agrees to the arrangement in a confirmed writing that includes each lawyer's share; and the total fee is reasonable.
Those are the model rule's conditions — the ABA writes model texts, and the version your state adopted is the one that governs your firm.
Note what the rule supplies and what it does not: three conditions, no percentages.
A firm looking for a standard origination split will not find one in the rule, and our research found no source establishing one anywhere else; the split between firms is set by the firms.
One condition is the one that exists only if someone drafts it: the client's agreement must sit in a confirmed writing that includes each lawyer's share.
A division that is proportional, reasonable and agreed in conversation — but never confirmed in writing — has not met the model rule's terms.
The engagement structure is the first thing to settle for that reason: whether the contract attorney invoices as a separate practice or works inside the firm bears on whether these conditions apply at all, and how your state treats a given structure is a question for your state bar's ethics counsel.
Conflicts and confidentiality duties for contract lawyers
Billing is one side of the arrangement.
The other side — who answers for the work — is where the opinions are clearest.
As the ISBA records it, 08-451 concluded that a lawyer who outsources services remains ultimately responsible for them under Model Rules 5.1 and 5.3 (the summary in the first section above; the ABA original stays unread here).
ISBA Opinion 19-04 works in the same register: outsourcing is allowed if it contributes to competent representation, with reasonable confidentiality and conflict measures.
Rules 5.1 and 5.3 are the supervision rules.
On the model text, Rule 5.1 asks partners and lawyers with comparable managerial authority to have measures giving reasonable assurance that the firm's lawyers conform to the rules of professional conduct, and asks a lawyer with direct supervisory authority over another lawyer to make reasonable efforts toward the same end.
Rule 5.3 carries the matching structure for nonlawyer services: on the model text, partners and lawyers with comparable managerial authority must make reasonable efforts to ensure the firm has measures giving reasonable assurance that nonlawyers' conduct is compatible with the lawyer's professional obligations (5.3(a)), and a lawyer with direct supervisory authority over a nonlawyer owes reasonable efforts to the same end (5.3(b)).
A contract attorney is a lawyer, so the lawyer-supervision rule bears on the outsourced lawyer's work — with Rule 5.3 in the picture whenever nonlawyer support travels with the engagement.
What those measures look like for a specific engagement — which conflicts check runs, what the confidentiality instruction covers, who reviews the work — is a mechanics question, and the sources on record state the standard rather than the checklist.
Our guide to outsourcing legal work builds the vendor file, and our guide to hiring for your law firm is the employer map this page sits inside.
Employer information, not legal advice. This page describes ABA model rules and ABA formal opinions as one state bar association's opinion records them, plus that association's advisory view; the rules your state adopted control. Confirm billing, disclosure and fee-division requirements with your state bar's ethics counsel before you structure the arrangement.
Questions to settle before the first contract attorney invoice
- Which lane the invoice sits in — a cost passed through at what the firm pays, or part of the firm's fee for services
- The engagement structure — your employee, or a separate practice whose fee Rule 1.5(e) conditions could reach
- If the fee is divided: proportional to services or joint responsibility, a confirmed writing that includes each share, and a reasonable total fee
- What the client is told about the arrangement, and when — per your state bar's position on disclosure and informed consent
- The conflicts and confidentiality measures for the engagement, documented before work moves
- How your state's adopted rules differ from the model text — confirmed with your state bar's ethics counsel
Questions employers ask
Can you bill a client more than you pay a contract attorney?
No source on record hands a firm a percentage.
What the verified record gives is the frame around the question: outsourcing is permissible when it contributes to competent representation with reasonable confidentiality and conflict measures, and client disclosure and informed consent are ordinarily required (ISBA Op.
19-04, an Illinois State Bar Association advisory opinion, persuasive only); and where a fee is divided between lawyers in different firms, ABA Model Rule 1.5(e) sets conditions, including a reasonable total fee — the version your state adopted controls.
Our research found no source establishing a standard markup figure — how a given arrangement is treated in your state is a question for your state bar's ethics counsel.
Does Model Rule 1.5(e) apply to a solo contract attorney?
It may.
The model rule governs divisions of a fee between lawyers who are not in the same firm, and a solo contract attorney practicing through their own firm is a different firm from yours.
Whether paying that attorney counts as dividing a fee is not settled by anything our research verified — ABA Formal Opinions 88-356 and 00-420 bear on contract lawyers, and we did not read them.
Where the rule does reach the arrangement, its conditions are that the division is proportional to services or each lawyer assumes joint responsibility, the client agrees in a confirmed writing that includes each share, and the total fee is reasonable.
Confirm how your state's adopted version treats the engagement with your state bar's ethics counsel.
Do I have to tell my client I am using a contract attorney?
The clearest statement in our research is ISBA Opinion 19-04 (October 2019, Illinois): disclosure to, and informed consent by, the client will ordinarily be required when work goes outside the firm, and informed consent is always required if complete or substantial responsibility for a matter is delegated or transferred to an unaffiliated lawyer.
It is one state's advisory opinion — persuasive rather than binding — so firms elsewhere should confirm their own state bar's position before relying on it.
What is ABA Formal Opinion 00-420?
It is the ABA formal opinion on billing contract lawyers' costs, cited by ISBA Opinion 19-04 alongside Formal Opinion 88-356 on temporary lawyers.
Our research did not read either opinion's contents, so this page cannot summarize what they conclude.
If your firm is pricing contract lawyer time, read them directly or ask your state bar's ethics counsel how your state treats them — a title is not a holding.
