Plain-English Summary

Rule 705 covers two different things that share a name.

Adjudicative facts

The court must take judicial notice as provided by law. It may notice a fact not subject to reasonable dispute because it is generally known within the court's territorial jurisdiction or can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.

The court may notice on its own; it must if a party requests and supplies the necessary information. Notice may be taken at any stage.

Court records must be identified

Subsection (b)(2)(C) is the provision that catches practitioners. When noticing records, exhibits, or transcripts from the court file — in the same case or another — the court must identify the specific documents or items noticed. And a party requesting it must identify the specific items, or offer to the court and serve on all parties copies of those items.

"The court file" is not a request. Family cases accumulate years of filings and often run alongside protection order and modification files; the rule forces a party to name what it wants noticed so the record on appeal shows what the court actually considered.

Being heard, and the effect

On timely request a party is entitled to be heard on the propriety of taking notice and the nature of the fact — and still entitled if the court took notice before notifying the party. Then the consequence: the noted fact is a conclusive finding. Not a presumption, not evidence to be weighed. That is why the opportunity to be heard matters.

The law of another state

A party intending to ask the court to notice the statutes or laws of a foreign state must submit a memorandum citing the foreign law to the court and opposing counsel at least 14 days before trial or hearing. The court may deny the request for failure to submit one. The opposing attorney may reply within 7 days of service.

This comes up constantly in family law — a marriage, divorce, custody order or support order from another state, or a foreign premarital agreement. Rule 705(c) is what makes it usable, and the 14-day memorandum is the price.

Frequently Asked Questions

What facts can the court judicially notice?

Rule 705(b)(1) allows the court to notice a fact that is not subject to reasonable dispute because it is generally known within the court's territorial jurisdiction or can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.

Can I ask the court to notice the whole file?

No. Rule 705(b)(2)(C) requires a party requesting judicial notice of records, exhibits or transcripts from the court file in the same or a separate case to identify the specific items, or offer to the court and serve on all parties copies of those items.

What is the effect of a judicially noticed fact?

Rule 705(b)(5) provides that the noted fact is a conclusive finding.

Can I object to judicial notice?

Rule 705(b)(4) entitles a party on timely request to be heard on the propriety of taking judicial notice and the nature of the fact, and preserves that right on request even if the court took notice before notifying the party.

How do I get the court to apply another state's law?

Rule 705(c)(1) requires a memorandum citing the foreign law to be submitted to the court and opposing attorney at least 14 days prior to trial or hearing, and allows the court to deny the request for failure to submit one. Rule 705(c)(2) allows a reply within 7 days.
