Protected and Registered Series LLC Formation Requirements in Idaho

Short answer Idaho's current Limited Liability Companies chapter provides for an ordinary LLC formed through a certificate of organization. The complete current Chapter 25 and Title 30 chapter index provide no domestic protected, registered, or designated series establishment procedure or statutory interseries liability rule. The chapter permits additional certificate terms but does not turn an internal division into a statutory protected series.

Ordinary LLC formation under current Chapter 25

Idaho Code § 30-25-101 names the LLC Act. Under § 30-25-201(a), one or more organizers form an LLC by delivering a certificate of organization for filing. Its ordinary LLC name is required under § 30-25-201(b)(1), and the LLC forms when that certificate becomes effective under § 30-25-201(d).

The current official Title 30 chapter index places the LLC Act in Chapter 25; the complete current Chapter 25 contains no domestic protected-, registered-, or designated-series establishment provision or statutory parent/series liability-segregation rule.

What trips people up

Under § 30-25-201(c), the ordinary LLC certificate may include additional terms within statutory limits, but the Secretary of State does not accept operating agreements for filing. Those ordinary-document provisions do not establish a protected series or provide a statutory interseries liability rule.

Common questions

Does an internal division become a protected series when the LLC forms? No. Section 30-25-201(d) concerns the ordinary LLC's effective formation. The current chapter has no separate domestic series establishment event.

Can an operating agreement be filed as a series designation? Section 30-25-201(c) says the Secretary of State will not accept an operating agreement for filing; current Chapter 25 supplies no domestic series designation filing.

This page gives general legal information about an ordinary domestic LLC's statutory route to establish a protected, registered, or designated series. It is not legal, tax, or financial advice. Governing documents, public filings, asset records, contracts, and the current statute determine which rules apply. The table does not determine whether a series is valid or its assets are protected in a particular dispute. Foreign-state, bankruptcy, tax, regulated-entity, and creditor rules may differ. Confirm current official law and obtain licensed advice for a specific structure or dispute.
