LLC Member Dissociation, Withdrawal, and Expulsion Requirements in Illinois

At a glance

Requirements one by one

Management form changes the power to leave

Under 805 ILCS 180/15-5(a)-(b), the operating agreement governs internal relations and may modify most Act rules, but it may not restrict the power to dissociate under § 35-50. It may determine whether dissociation is wrongful.

805 ILCS 180/35-50 then splits management forms. A member-managed member may dissociate at any time by express will. A manager-managed member has no power, rightfully or wrongfully, to leave before dissolution and winding up unless a written operating agreement specifies the time or events for exit.

Notice sets the voluntary date for a permitted exit

Under 805 ILCS 180/35-45, the LLC's notice of express will causes dissociation on the notice date or the member's stated later date. The section states no universal signature, advance period, acceptance, or company-consent condition.

An LLC whose original articles were filed and effective on or before January 1, 2001 remains under the pre-2001 version of § 35-50 unless a written agreement provides otherwise. The current section does not reproduce that historical rule, so formation date and the applicable official historical text must be checked rather than silently applying the modern branch.

Member-managed wrongfulness is agreement-based

A member-managed exit is wrongful only if it breaches an express agreement term. The member owes the LLC and the other members damages caused, in addition to other obligations. If the LLC continues instead of dissolving and winding up, company damages must be offset against distributions otherwise due after dissociation.

Section 35-50 states no parallel statutory wrongfulness/damages formula for a manager-managed exit authorized by written agreement. This survey does not decide breach, cause, amount, or offset computation.

Full transfer, expulsion, and court order are separate routes

Transfer of all distributional interest itself causes dissociation, except for security transfers and un-foreclosed charging orders. The operating agreement may separately provide expulsion.

The unanimous-other-member route covers illegality; substantially all of the distributional interest; uncured corporate status after 90-day notice; and a dissolved, winding-up partnership or LLC. The LLC or another member may seek judicial expulsion for materially adverse wrongful conduct, willful or persistent material agreement/duty breach, or conduct making continued business with the member not reasonably practicable.

Automatic events are not limited to member management

The insolvency list applies without a member-managed limitation and includes debtor bankruptcy, creditor assignment, voluntary trustee/receiver/liquidator events, and an uncured involuntary appointment after the statutory 90-day period. Individual death, guardian/conservator appointment, and incapacity order also apply across management forms.

Trust/estate distribution, qualifying entity termination, merger, conversion, and qualifying domestication complete the event list. The current section does not list completed winding up as a separate event.

Governance ends while economics and some records rights remain

Under 805 ILCS 180/35-55(a)-(b), member management ends and the former member is treated as a transferee. Loyalty and care continue only for pre-exit matters unless the person participates in winding up. The distributional interest becomes solely transferee-owned, and prior debts, obligations, and liabilities are not discharged.

805 ILCS 180/1-40(c)-(e) gives the transferee a particularized written proper-purpose records route, a ten-day response, and possible inspection, cost, and fee relief. The Act creates no current automatic buyout, redemption, fair-value payment, or forfeiture.

Member status and manager office remain separate. 805 ILCS 180/15-1(a), (c) permits nonmember managers and keeps a manager until successor qualification, resignation, or removal; § 35-55 does not itself end that separate office. Authority filings and public manager rosters remain separate.

What trips people up

• Management form changes power, not merely procedure. Silence blocks pre-winding-up exit for a manager-managed member.
• Illinois uses agreement breach for member-managed wrongfulness. It does not make every voluntary pre-winding-up exit wrongful.
• Full transfer ends membership. That is the opposite of statutes that leave the transferor as a member until separate expulsion.
• Damages have a mandatory offset route. If the LLC continues, company damages offset distributions otherwise due the former member.

Common questions

Can an Illinois member-managed LLC member leave at any time?

The statute gives the power to do so, but an express agreement breach makes the exit wrongful and potentially damages-bearing.

Can a manager-managed member leave without an agreement clause?

Not before dissolution and winding up. The agreement must specify the time or events in writing.

Does transferring the whole economic interest end membership?

Yes, subject to the security-transfer and un-foreclosed-charging-order exceptions in § 35-45(3).

Does dissociation require a buyout?

No current automatic buyout appears. The distributional interest continues in transferee status, subject to the agreement and other law.
