409A Valuation & Cap Table Audit Platforms4 min readUpdated September 2026

What an RIA's Client Consent Rules Mean for a 409A

Some RIA equity changes need client consent: under the Investment Advisers Act, an assignment of an advisory contract generally requires it, and a large enough change in who controls the firm can count as an assignment. Fee revenue that moves with market levels and a founder eyeing succession add documentation work on top of the valuation number.

Here's what actually drives the choice between Carta and Shareworks for registered investment advisors, and what to settle with compliance before either platform matters.

Criterion one: does this equity change count as an assignment

Ask your compliance team or outside counsel directly whether the specific ownership change you're planning, a new partner buying in, a founder transferring a controlling stake, crosses the threshold your advisory agreements and the Advisers Act treat as an assignment requiring client consent. The answer depends on the specific percentages and control provisions in your agreements, not a general rule of thumb, so get this confirmed in writing before you finalize a cap table change, not after clients start asking questions.

Criterion two: how to smooth AUM-driven fee revenue in the valuation

Advisory fee revenue tied to assets under management rises and falls with market levels in ways that have nothing to do with how well the firm is actually run, which means a single quarter's revenue can badly misrepresent the business. Ask your appraiser to build the valuation off a trailing period long enough to smooth normal market movement, and to note explicitly where current market levels sit relative to a longer average, so the number isn't quietly assuming today's conditions persist indefinitely.

Criterion three: what documentation an examiner actually wants to see

An SEC or state examiner reviewing a change in ownership wants a clean record: the valuation report itself, partner or board approval minutes, and evidence that client consent was properly obtained where required. Whichever platform administers your cap table, confirm it can export a complete audit trail on request, since a well-run equity plan with no accessible paper trail is nearly as much of a problem during an exam as a poorly run one.

Criterion four: key-person risk when one or two advisors hold most of the book

A firm where a founder or a small handful of senior advisors control most of the client relationships carries real key-person risk that should show up explicitly in the valuation's discount rate, not get glossed over. Document a concrete succession plan, who takes over specific client relationships, and how compensation and equity shift as that transition happens, since a documented plan meaningfully changes how an appraiser and, later, a buyer or examiner reads that risk.

Criterion five: matching the platform to your firm's structure

A single-location RIA extending its first options to a couple of senior advisors fits Carta's straightforward setup well. An RIA that's rolling up into or being acquired by a larger aggregator platform, common in wealth management right now, should ask what system the aggregator standardizes on before investing heavily in its own setup, since Shareworks' multi-entity handling tends to suit that kind of consolidated structure better once several advisory practices sit under one ownership umbrella.

What to put in writing before either platform matters

Get three things documented before you touch a cap table platform: written confirmation from counsel on whether the planned change is an assignment, a valuation built on a smoothed trailing period rather than one market-sensitive quarter, and a succession outline for your firm's most client-facing advisors. None of this is platform-specific, and skipping it to get to a faster valuation just moves the real risk later, usually to an exam or a diligence process where it's far more expensive to fix.

Have these documents in hand before you touch a cap table platform:

  • Written confirmation from counsel on whether the planned ownership change counts as an assignment that requires client consent.
  • A valuation built on a smoothed trailing period, not a single market-sensitive quarter of assets under management fees.
  • A succession outline naming who takes over specific client relationships and how compensation and equity shift as the transition happens.
  • A complete examiner-ready record: the valuation report, partner or board approval minutes, and evidence that client consent was obtained where required.
  • Confirmation that your chosen cap table platform can export a full audit trail on request.

A worked example: an aggregator standardizing across acquired practices

Say a wealth management aggregator has already acquired two other advisory practices in your region and is now in discussions to bring yours in as a minority-equity partner rather than a full buyout. The aggregator's own finance team may already have opinions about which cap table platform every acquired practice should eventually run on, and it's worth asking directly, before your firm signs anything, rather than assuming your existing setup will simply carry forward unchanged.

If the aggregator standardizes on Shareworks across its portfolio of practices, adopting that early avoids a second migration a year or two later once your firm's cap table has grown more complex with grants tied to the transaction itself. If no standard exists yet and your firm is one of the aggregator's earlier acquisitions, this is a reasonable moment to advocate for one, since your practice won't be the last advisory firm this aggregator brings in.

Either way, don't let the platform conversation get ahead of the compliance conversation. Confirm the assignment and client consent question first, get the valuation normalized properly for AUM-driven swings, and only then treat the platform choice as what it actually is: an administrative decision that follows the more consequential ones, not one that should drive them. A firm that reverses that order often ends up redoing paperwork it thought was already settled.

Executive Capability Standard

What Good Looks Like

A well-run RIA confirms with compliance counsel whether an ownership change requires client consent before finalizing it, and keeps a complete, exportable audit trail of valuations and approvals ready for an examiner.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Understand your advisory agreements' specific assignment and change-of-control provisions well enough to know when client consent is triggered.
2. Do Manually:Track AUM and fee revenue over a trailing period long enough to smooth normal market swings before any valuation conversation.
3. Delegate:Assign compliance counsel to review every planned ownership change against the Advisers Act's assignment rules before it's finalized.
4. Automate:Use Carta or Shareworks to keep an exportable, complete audit trail of grants, approvals, and valuation dates ready for an exam.
5. Buy:Document a concrete succession plan for client relationships tied to your most senior advisors, reviewed and updated as the book changes.

Frequently Asked Questions

Does every ownership change at an RIA require client consent?

Not every change, only those that count as an assignment of the advisory contract under the Investment Advisers Act, which depends on specific control thresholds in your agreements. Confirm the specific transaction with compliance counsel rather than assuming either a blanket yes or no applies.

Should our valuation assume current market conditions will continue?

No. A defensible valuation smooths AUM-driven revenue over a trailing period long enough to avoid overweighting a single strong or weak market quarter, and should note explicitly where current conditions sit relative to a longer average rather than extrapolating flatly.

What happens if we skip client consent on a qualifying ownership change?

That's a compliance and legal question with real regulatory exposure, not something either cap table platform addresses. Loop in compliance counsel before finalizing any ownership change large enough to plausibly qualify as an assignment, and document the consent process thoroughly if it applies.
