California brokers arranging private mortgage loans on multiple lender-investors operate under one of two statutory frameworks: §10238, which governs the fractional undivided interest model capped at ten investors, and §10238.1, which governs the series-note model for pools above that threshold. Which statute applies controls investor count, documentation, DRE registration, and broker fiduciary obligations from origination through servicing.

Note Structure

Under §10238, a single promissory note evidences the borrower’s obligation, and each lender-investor takes a fractional undivided interest in both the note and the deed of trust. All investors share one collateral instrument recorded against the property.

Under §10238.1, each investor holds a separate promissory note — a distinct borrower obligation — against pooled collateral. There is no single note in which fractional interests are carved; the series generates individual note instruments for each participating investor.

Investor Count Cap

The ten-investor cap is §10238’s defining constraint. It governs at origination and on every subsequent partial purchase or assignment. Any transaction that would push the investor count above ten triggers a statutory violation requiring a restructure or cure before it can proceed.

§10238.1 exists precisely for pools that exceed ten investors. The series-note filing with the California Department of Real Estate enables larger arrangements without breaching the §10238 cap, because each investor relationship is a separate note rather than a fractional interest in a single instrument.

Documentation Requirements

Both structures require the §10240 Mortgage Loan Disclosure Statement to the borrower. That obligation is common ground.

The §10238 documentation stack adds a §10232.5 lender disclosure to each investor, the single recorded promissory note, the single recorded deed of trust, and a fractional-interest assignment instrument for each lender-investor position.

§10238.1 replaces the fractional-interest instruments with separate notes for each investor and adds the series-note disclosure framework specific to that statute. The DRE registration filing is a §10238.1 requirement with no equivalent in the §10238 structure.

DRE Registration

A §10238 multi-lender arrangement carries no separate DRE registration beyond the broker’s existing license and threshold-broker reporting under §10232.4 where applicable.

§10238.1 requires a series-note registration filing with the DRE before the arrangement launches. That filing triggers a disclosure document review and DRE approval process. The registration governs the pooled-collateral arrangement and the investor disclosure framework for the life of the series.

Broker Fiduciary Obligations

Under §10238, the broker’s fiduciary duty runs to each lender-investor in proportion to that investor’s fractional interest in the single note. The broker is responsible for the full cycle: disclosure, underwriting, closing, and ongoing servicing of the fractional pool.

Under §10238.1, the fiduciary duty runs to each investor against their individual note, with the pooled-collateral arrangement creating an additional coordination layer. The series-registration disclosure framework defines the investor protection structure for the life of the pool.

Trust Account and Payment Distribution

Both structures require the broker to maintain a §10145 trust account for closing funds and post-closing borrower payments. The discipline is the same; the distribution mechanics differ.

Under §10238, distributions flow pro-rata to each lender-investor according to their fractional interest in the single note. Under §10238.1, distributions are allocated per investor based on the terms of each separate note. Neither structure permits commingling trust funds with the broker’s operating account.

Servicing Obligations

Servicing obligations run parallel across both structures. The broker must handle monthly payment collection, investor distributions, impound disbursements where applicable, §6050H Form 1098 reporting, §1024.35 error-resolution procedures, and — on residential consumer-purpose loans — §1026.41 periodic statements under Regulation Z.

§10238(k) codifies the servicing framework for the multi-lender structure. §10238.1 applies its own servicing framework, tied to the series registration. The underlying compliance obligations are substantively similar, though the statutory authority and reporting anchors differ.

Handling Structural Changes After Closing

In a §10238 structure, partial purchases, assignments, and lender-investor changes must always keep the investor count at ten or below. Any change that would breach the cap requires a restructure or statutory cure before it can proceed.

§10238.1 handles investor changes through the series filing framework. Because the series registration governs a larger pool without a fixed ten-investor ceiling, investor transitions operate under the registered document’s procedures rather than against a hard statutory cap.

The Structure Decision

The practical decision point is investor count at origination. For deals with ten or fewer investors, §10238 offers a direct documentation path with no DRE registration step. For deals above ten, §10238.1 is the required framework — and its upfront registration and disclosure review represent a material additional process that takes time to complete.

Brokers who regularly arrange private mortgage loans at portfolio scale — consistently bringing large investor groups into individual loans — generally find that establishing the §10238.1 registration infrastructure makes repeated execution more systematic than navigating the §10238 cap deal by deal.

Expert Take

The §10238 cap is not a paperwork technicality. It is a structural constraint that applies at every closing and every subsequent transfer. A broker who does not build investor-count tracking into their origination workflow will eventually breach it — typically not at origination but months later, when a partial purchase pushes an unmonitored deal above ten. The §10238.1 registration process exists to solve that problem at scale, but it requires planning well before the first closing. Brokers who discover the cap problem after the fact face a cure process that is far more disruptive than the registration step they skipped.
