Protected and Registered Series LLC Formation Requirements in Texas

Short answer A Texas LLC company agreement may establish a protected series without a series-level certificate; a registered series requires a certificate filed with the Secretary of State. For the statutory separation of obligations, the parent certificate must give notice, the company agreement must state the limitation, and records must account separately for each series’s associated assets. A registered certificate costs $300 and its name must include the parent LLC’s name and a registered-series indicator.

Requirements one by one

Protected versus registered route

Tex. Bus. Orgs. Code § 101.601(a) lets the company agreement establish or provide for one or more series. Section 101.602(e)-(f) treats a qualifying series without a filed registered-series certificate as a protected series. A registered series needs a certificate under §§ 101.602(c) and 101.623(a); the LLC executes it and files it with the Secretary of State. Section 101.623(b) requires parent and series names and a conversion/merger statement if applicable. Its filing fee is $300 under § 4.162(a)(1).

Parent notice, records, and liability limitation

Section 101.602(a)-(b) limits a series obligation to that series’s assets and excludes parent and other-series assets, and also protects the series against their obligations, only to the extent three conditions are met: separately accounted-for series assets, company-agreement limitation language, and notice in the parent certificate of formation. § 101.604(a) says parent-certificate notice need not name a particular series or use the words “protected” or “registered.” § 101.603(b) allows records to identify assets by specific listing, category, quantity, allocational formula, or another objective method; subsection (a) permits holding through the parent or a nominee. Section 101.602(d) allows specified express agreements making other assets answerable.

Registered-series name and later filings

A registered-series name must contain the parent LLC name and the registered-series phrase or abbreviation under §§ 101.626 and 5.0561. Changing a registered certificate requires a filed amendment under § 101.624, with a $150 fee under § 4.162(a)(2). Section 101.615 distinguishes termination: a protected series terminates after winding up, whereas a registered series also needs an effective filed termination certificate. § 101.625 supplies that certificate’s contents; § 4.162(a)(3) sets a $40 fee. § 101.616 lists winding-up events, including the parent’s winding up, agreement events, specified votes, and court order.

What trips people up

A filed registered-series certificate does not amend the parent certificate (§ 101.623(e)); the parent’s liability-limitation notice remains a separate § 101.602(b)(3) condition. A company agreement can also establish a non-protected, non-registered series under § 101.601(c), but that alone does not invoke § 101.602(a)’s asset limitation. § 101.622 says protected and registered series are not separate domestic entities or organizations for the specified Texas title and chapter.

Common questions

Does every Texas protected series require a certificate?

No. Section 101.602(f) identifies the qualifying series without a registered certificate as a protected series; the registered route uses § 101.623.

Must the parent certificate name each series?

No. § 101.604(a)(2) says its notice of limitation need not reference a specific protected or registered series.

Can a series end while the parent remains?

Yes, subject to the agreement and statutory winding-up provisions. § 101.614 permits a series to wind up without winding up the parent; § 101.615 adds a termination filing for registered series.

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.
