With AI, what should we do in-house and what should outside counsel do?
When it comes up
During budget planning, panel reviews, when AI makes a category of work much faster, or when the business asks for faster turnaround.
Your options
Bring routine work in-house with AI
Fits when: High-volume, playbook-driven work: NDAs, standard contracts, first-pass research, regulatory digests.
Watch out: Needs tools, playbooks and capacity; don't overload a small team.
Keep with outside counsel on new AI-aware pricing
Fits when: Specialist, high-stakes or surge work, where firms use AI and share efficiency through fixed or capped fees.
Watch out: Firms may not pass on savings unless you ask and measure.
Alternative legal service providers with AI
Fits when: Large-volume review, contract migration and data extraction projects.
Watch out: Check quality controls, confidentiality and supervision duties.
Hybrid on a shared platform
Fits when: Ongoing matters where in-house and firm teams work together on the same AI-assisted analysis.
Watch out: Agree data ownership, access and confidentiality on the shared platform.
How to decide
- Map matter types by volume, risk and specialism.
- Ask what AI changes for each: speed, cost, required expertise.
- Decide by tier: routine → in-house with AI or ALSP; specialist or high-stakes → outside counsel on AI-aware pricing.
- Update guidelines for AI disclosure, confidentiality, verification and billing.
- Measure spend and quality by matter type each quarter.
Trade-offs
In-sourcing saves fees but needs capacity, tools and supervision; outsourcing keeps flexibility and expertise but only saves money if pricing changes. Most departments end up hybrid.
