Realistic Timeline: Moving a $250M Wirehouse Book to a New RIA in 6 Months
Realistic Timeline: Moving a $250M Wirehouse Book to a New RIA in 6 Months
A $250M wirehouse book can transition to an independent RIA in six months when pre-resignation prep starts at month one, the resignation lands at the end of month three, and ACATS runs in concentrated waves through months four and five. Most advisors miss this window because they treat resignation as the start of the timeline rather than the midpoint. The six-month plan below assumes 180 households, a single custodian, and a transition platform that automates document prep and NIGO triage.
What "Realistic" Actually Means
A 6-month timeline is realistic, not aggressive. Industry data from the Diamond Consultants 2025 breakaway survey shows the median wirehouse-to-RIA transition for $200M–$300M books takes 7.4 months from "decision to move" to "90% of AUM custodied at new firm." The slowest decile takes 13 months. The fastest decile finishes in 4.5 months, and they all have one thing in common: structured pre-resignation prep starting at least 60 days before the resignation date.
The 6-month plan is the median-plus-buffer scenario. It assumes a non-protocol wirehouse exit (the tighter constraint), a single primary custodian at the new RIA, and roughly 180 client households split across taxable brokerage, IRAs, and a small number of trust accounts.
The Six-Month Timeline at a Glance
| Phase | Months | Key Activities | Critical Milestone |
|---|---|---|---|
| Pre-Resignation Prep | 1–3 | Licensing, custodian onboarding, ADV, counsel review | All accounts pre-mapped to new custodian |
| Resignation Window | End of 3 | U5 trigger, day-1 calls, ACATS wave 1 | 30% of AUM authorizations signed within 7 days |
| Active Repapering | 4–5 | ACATS waves 2–4, NIGO remediation, billing setup | 80% AUM custodied by end of month 5 |
| Tail & Stabilization | 6 | Trust accounts, alternatives, ERISA cleanup | 95%+ AUM, billing reconciled, ops handed off |
Months 1–3: Pre-Resignation Prep
The first three months are the highest-leverage period of the entire transition. Nothing client-facing happens, but everything that happens here saves weeks during the resignation window.
Month 1 — Foundation. Engage employment counsel (estimate $8K–$15K for the full transition). File Series 65 verification or sponsor transfer paperwork. Sign the contract with the new RIA platform or finalize your own RIA's SEC/state registration. Begin Form ADV Part 2 drafting. Open the custodian onboarding workflow at Schwab, Fidelity, or Pershing — the custodian's transitions team typically needs 30–45 days to fully provision an advisor of this size.
Month 2 — Inventory and Mapping. Build the master account inventory: every household, every account number, every registration type, every annuity or alternative position. Map each account to the destination custodian and the destination registration. This is where most transitions hide weeks of work — the mapping needs to happen before resignation because the advisor cannot legally pull custodian-side data after they leave.
Month 3 — Document Templates and Communication Plan. Pre-populate ACATS forms, advisory agreements, and IPS templates with the client data captured in legally permissible exports. The transition platform should generate per-household packets ready to send within 48 hours of resignation. Draft the client communication script, the Day-1 call list (top 20 households by AUM), and the resignation letter. Set the resignation date for the last Friday of month 3.
End of Month 3: The Resignation Window
Friday afternoon resignation. The wirehouse files Form U5 within 30 days (some firms file same-day, others slow-walk it to day 28). The advisor cannot solicit clients until U5 is on file and state notification requirements are met — typically 5–10 business days post-resignation.
The first week post-resignation is for outreach, not paperwork. The top-20 households get personal calls. The next 60 households get a templated email plus a 15-minute scheduled call. The remaining 100 get a personalized letter and an inbound contact request.
By the end of week 2 post-resignation, 30% of the AUM should have ACATS authorizations signed. This is the leading indicator that the transition is on track.
Months 4–5: Active Repapering and ACATS Waves
This is the operational core. The platform's job is to run ACATS in concentrated waves, batch NIGO remediation, and stand up the new billing relationship.
Wave 1 (Week 1 of month 4): The top 20 households. These are usually the highest-quality data and lowest NIGO risk. Submit ACATS in a single batch. NIGOs come back within 5 business days; remediate within 48 hours.
Wave 2 (Weeks 2–3 of month 4): Households 21–80. Larger batch, higher NIGO risk because of edge cases (trusts, joint accounts, custodial accounts for minors). Expect a 25–40% NIGO rate on the first submission. AI-driven NIGO triage that auto-categorizes the rejection reason (signature mismatch, registration mismatch, missing Letter of Acceptance, etc.) cuts the remediation time from days to hours.
Wave 3 (Weeks 1–2 of month 5): Households 81–140. These are often clients who needed a second call or a printed packet. NIGO rates climb because data quality drops. The platform's role is to flag which households need a personal touchpoint before resubmission.
Wave 4 (Weeks 3–4 of month 5): Households 141–180. The long tail. Some clients delay decisions; a small percentage (typically 3–7%) churn. Plan for a 90% AUM retention rate as the realistic baseline — the wirehouse will be actively counter-pitching during this window.
By the end of month 5, 80% of AUM should be custodied at the new firm and producing billable fees.
Month 6: Tail and Stabilization
Month 6 handles the operational long tail: trust account re-registration (slow because of trustee approvals), alternative investments (slow because of GP signoff), 401(k) consulting accounts (ERISA paperwork requires plan sponsor signature), and any accounts held away that the advisor wants to consolidate.
The other major month-6 task is billing reconciliation. The new RIA bills in arrears or in advance; the wirehouse's last billing cycle creates pro-ration questions. Each client gets a personalized fee summary covering the transition period. Expect 30–50 hours of ops time on billing reconciliation alone.
By the end of month 6, the target is 95% of pre-transition AUM custodied, billing reconciled, advisory agreements signed and indexed, and the operational handoff to the new firm's ongoing service team complete.
Where Transitions Fall Behind Schedule
Five categories cause 90% of timeline slippage:
- Late pre-resignation prep. Starting at month 2 instead of month 1 pushes everything back by 30 days.
- Custodian onboarding delays. If the custodian's transitions team is backlogged, expect 60+ days instead of 30. Build this risk into the plan.
- NIGO compounding. Without AI-driven triage, each NIGO cycle adds 5–10 days, and a single account can hit 3–4 cycles.
- U5 delays. Some wirehouses file U5 at day 28 instead of day 7. Track this proactively and escalate at day 14.
- Client decision drag. 15–20% of clients take 60+ days to decide. Plan a structured re-contact cadence at day 30, 45, and 60.
The Honest Tradeoffs
A 6-month timeline assumes the advisor accepts a 5–10% AUM loss during the transition. Pushing harder for retention extends the timeline to 8–10 months but recovers maybe 2–3 percentage points of AUM. Most advisors find the 6-month/90% retention combination is the best economic outcome — the dark-period cost of an extra 60 days outweighs the marginal AUM saved.
The other tradeoff is operational headcount. Doing this without a transition platform requires 1.5–2.0 dedicated FTEs for six months. With a platform that automates document generation, NIGO triage, and ACATS tracking, the same book is manageable with 0.5–0.75 FTE plus the advisor's own time.
FAQ
How long does it really take to move a $250M wirehouse book to an RIA? A realistic median is 6 months from resignation date to 90% AUM custodied, assuming 60+ days of pre-resignation prep. Without prep, expect 8–10 months and a higher AUM loss rate.
What percentage of AUM should I expect to retain? Industry data shows 85–95% AUM retention is realistic for protocol wirehouse exits with strong client relationships. Non-protocol exits run 75–90%. Books with weak relationship depth (5%+ of AUM from clients seen less than annually) retain at the low end of these ranges.
When should I start pre-resignation prep? Month 1 of the 6-month plan. Engaging employment counsel, beginning custodian onboarding, and building the account inventory all take 60+ days and cannot legally happen post-resignation.
What's the single biggest accelerator? AI-driven NIGO triage. NIGO rejections compound — a single account with three NIGO cycles can take 30+ days. Auto-categorizing rejections and routing them to the right remediation path cuts the average ACATS-to-funded time from 21 days to 9 days.
Can a $250M book transition in less than 6 months? Yes, with two conditions: (1) protocol wirehouse exit so clients can be contacted day-1, and (2) a transition platform doing document generation and NIGO triage. The fastest decile of $200M–$300M transitions finish in 4.5 months under those conditions.
