The short answer
What Illinois families should know.
Losing a motion does not automatically make it frivolous. Illinois Supreme Court Rule 137 focuses on the factual and legal basis for signed filings and whether they were submitted for an improper purpose. The remedy depends on the actual violation and the procedure used to present it.
A signature carries a certification
Under Rule 137, an attorney or self-represented party signs pleadings, motions, and other covered documents. That signature certifies reasonable inquiry into the facts and law and that the filing is not for harassment, unnecessary delay, or needless litigation expense. A good-faith argument to change existing law is not forbidden merely because it is unsuccessful. The relevant questions include what was asserted, what could reasonably have been investigated, and the basis available when the filing was made.
Connect the problem to a specific paper
Identify the challenged allegation or legal contention and the evidence showing why it lacked a reasonable basis. Separate an unsupported claim from a genuine factual dispute that required a hearing. An insulting communication or difficult negotiation is not automatically a Rule 137 filing violation. Other rules and statutes may govern different conduct, including discovery misconduct. A sanctions request should identify the proper authority and attributable expenses rather than combining every frustration in the case into one demand.
Observe the sanctions procedure and deadline
Rule 137 proceedings occur in the same civil action, not as a new lawsuit based solely on the rule. The rule provides a filing deadline tied to final judgment or disposition of a timely postjudgment motion. Its ordinary period is 30 days, but the relevant triggering event must be identified accurately. The court may impose an appropriate sanction and must give specific reasons when it does so. A requested award is not automatic reimbursement for the entire divorce. Consider whether resolving the disputed issue directly will protect the client more effectively than expanding collateral litigation. If a factual error is discovered, tell counsel promptly and preserve the records explaining it. The response should address correction and procedure instead of defending an inaccurate statement after its basis is known.
