Best practices for using AI in financial planning
AI is reshaping how plans are built, reviewed and explained. It speeds up the grunt work-organizing data, surfacing issues and turning dense documents into something usable. What it doesn't replace is judgment, context or the conversations that make a plan real for a family.
If you work in finance, treat AI like a force multiplier. Use it to make analysis sharper and meetings shorter, while keeping control of decisions, compliance and client trust.
Where AI actually adds value
AI's upside is efficiency. It gets you to a workable draft faster so you can spend more time on strategy and client dialogue. Strong use cases include:
- Summarizing complex documents: Pull key provisions from wills, trusts, LLC/partnership agreements and POAs. Always review-models can miss details or invent them in dense legal language.
- Diagramming estate plans: Generate flowcharts that show asset flows, distribution terms and entity roles. Great for client education and internal alignment.
- Spotting gaps and mismatches: Flag outdated trustees, inconsistent beneficiaries or missing documents. Free up hours of admin work and direct attention to issues that matter.
Where AI falls short
Accuracy is the biggest risk. Wrong summaries or missed provisions can ripple into bad assumptions. Recent tests showed popular assistants giving incorrect details on 529 rules and estate tax exemptions-omitting items from new law or citing the wrong year.
AI also can't read intent or family dynamics. It doesn't understand "why" a client chose a distribution structure or how siblings actually get along. That's where your experience, process and client conversations matter most.
Security and confidentiality: treat data like a live wire
Planning files often include highly sensitive information:
- Social Security numbers and dates of birth
- Account numbers and balances
- Real estate holdings and business interests
One careless upload to a public tool can expose a client to identity theft, fraud or unwanted visibility. Even large platforms have had features that made shared conversations discoverable via search. Keep anything identifiable out of public models-full stop.
Use AI responsibly: practical guardrails for finance teams
- Pick the right platform: Favor closed systems purpose-built for financial and legal work, with clear data isolation, audit trails and enterprise controls.
- Zero sensitive data in public tools: No SSNs, account numbers, full documents or client identifiers. Redact or use synthetic examples for prompts.
- Always verify outputs: Cross-check AI summaries and numbers against source documents and primary references like the IRS estate and gift tax page.
- Keep a human in the loop: Require sign-off for any client-facing output. Document who reviewed, what changed and why.
- Create prompt templates: Standardize prompts for document summaries, plan diagrams and data checks to improve consistency and reduce errors.
- Log usage for compliance: Capture prompts, outputs, reviewers and final decisions. Store alongside the client record.
- Vendor due diligence: Review model provenance, data retention, fine-tuning policies, SOC2/ISO status and breach history.
- Minimize data exposure: Redact, chunk documents and share only what's needed for the task at hand.
- Train your team: Teach limits, failure modes and red flags (confident wrong answers, missing citations, legal nuance).
- Set clear client expectations: Explain how AI supports your process and where human advice leads.
A simple workflow you can implement this quarter
- 1) Intake: Collect documents, classify them and auto-redact sensitive fields before any AI touch.
- 2) Summarize: Generate structured memos (key parties, roles, distribution terms, control provisions, dates) and a one-page client brief.
- 3) Visualize: Create estate flowcharts and entity maps to clarify ownership and transfers.
- 4) Validate: Compare AI outputs to source docs; confirm tax figures against primary sources; note all corrections.
- 5) Advise: Use the summaries to focus your meeting on goals, trade-offs and decisions.
- 6) Record: Store final materials, reviewer notes and decisions in your system of record.
What to measure
- Cycle time: Hours from document intake to draft plan and to final sign-off.
- Error rate: Number and severity of corrections per plan before client delivery.
- Client clarity: Survey scores on understanding of plan structure and trade-offs.
- Advisor capacity: Time reallocated from admin to strategy and client work.
- Compliance findings: AI-related issues caught in QA and audits.
Final take
AI makes financial planning faster and clearer when it's used with guardrails. Let it do the organizing and pattern-spotting. Keep humans in charge of accuracy, intent and tough decisions.
