RULE 1.3: DILIGENCE

A lawyer shall act with reasonable diligence and promptness in representing a client.

Adopted July 1, 2009, effective January 1, 2010.

Comment

[1] A lawyer should pursue a matter on behalf of a client despite opposition, obstruction or

personal inconvenience to the lawyer, and take whatever lawful and ethical measures are required

to vindicate a client’s cause or endeavor. A lawyer must also act with commitment and dedication

to the interests of the client and with zeal in advocacy upon the client’s behalf. A lawyer is not

bound, however, to press for every advantage that might be realized for a client. For example, a

lawyer may have authority to exercise professional discretion in determining the means by which

a matter should be pursued. See Rule 1.2. The lawyer’s duty to act with reasonable diligence does

not require the use of offensive tactics or preclude the treating of all persons involved in the legal

process with courtesy and respect.

[2] A lawyer’s work load must be controlled so that each matter can be handled competently.

[3] Perhaps no professional shortcoming is more widely resented than procrastination. A

client’s interests often can be adversely affected by the passage of time or the change of conditions;

in extreme instances, as when a lawyer overlooks a statute of limitations, the client’s legal position

may be destroyed. Even when the client’s interests are not affected in substance, however,

unreasonable delay can cause a client needless anxiety and undermine confidence in the lawyer’s

trustworthiness. A lawyer’s duty to act with reasonable promptness, however, does not preclude

the lawyer from agreeing to a reasonable request for a postponement that will not prejudice the

lawyer’s client.

[4] Unless the relationship is terminated as provided in Rule 1.16, a lawyer should carry

through to conclusion all matters undertaken for a client. If a lawyer’s employment is limited to a

specific matter, the relationship terminates when the matter has been resolved

does not preclude

the lawyer from agreeing to a reasonable request for a postponement that will not prejudice the

lawyer’s client.

[4] Unless the relationship is terminated as provided in Rule 1.16, a lawyer should carry

through to conclusion all matters undertaken for a client. If a lawyer’s employment is limited to a

specific matter, the relationship terminates when the matter has been resolved. If a lawyer has

served a client over a substantial period in a variety of matters, the client sometimes may assume

that the lawyer will continue to serve on a continuing basis unless the lawyer gives notice of

withdrawal. Doubt about whether a client-lawyer relationship still exists should be clarified by the

lawyer, preferably in writing, so that the client will not mistakenly suppose the lawyer is looking

after the client’s affairs when the lawyer has ceased to do so. For example, if a lawyer has handled

a judicial or administrative proceeding that produced a result adverse to the client and the lawyer

and the client have not agreed that the lawyer will handle the matter on appeal, the lawyer must

consult with the client about the possibility of appeal before relinquishing responsibility for the

matter. See Rule 1.4(a)(2). Whether the lawyer is obligated to prosecute the appeal for the client

depends on the scope of the representation the lawyer has agreed to provide to the client. See Rule

1.2.

[5] To prevent neglect of client matters in the event of a sole practitioner’s death or disability,

the duty of diligence may require that each sole practitioner prepare a plan, in conformity with

applicable rules, that designates another competent lawyer to review client files, notify each client

of the lawyer’s death or disability, and determine whether there is a need for immediate protective

action. See Illinois Supreme Court Rule 776, Appointment of Receiver in Certain Cases.

Adopted July 1, 2009, effective January 1, 2010.
