AI in Law for Legal Pros to Stay Relevant by Client Relationships and Business Thinking - Roger Bull
Law firms invest heavily in lateral partners, yet many hires fail to deliver the expected commercial or strategic return. With around 60% of lateral partner hires not seen as successful, the risk is too large to treat onboarding as administration.
The problem often persists because integration falls between recruitment, talent and learning teams. Once the contract is signed, the people closest to the original business case can lose ownership of the final stage.
Roger Bull, Managing Partner of Burges Salmon LLP, brings a useful law firm leadership lens to this issue. He has spent nearly 32 years at the leading independent UK firm, which has offices in Bristol, London and Edinburgh.
The sections below break down what senior law firm leaders can learn from that perspective, and how lateral partner integration can protect recruitment investment, partner confidence and long-term retention.
Why lateral partner integration belongs inside recruitment
The commercial case for a lateral partner is usually made before arrival. The integration plan should therefore be treated as part of that same recruitment decision, not as a later, optional exercise.
The hire is not complete at acceptance
A signed offer does not transfer relationships, internal trust or fee-earning momentum. Those outcomes depend on introductions, sponsorship, client planning and early confidence once the partner joins.
Ownership should follow the investment
Recruitment teams are closest to the business case, the sponsor's rationale and the risks identified during due diligence. That makes them well placed to retain ownership of integration strategy, while working closely with L&D, business development and practice leadership.
A confidential space reduces silent drift
Laterals may arrive with private concerns about expectations, internal politics, client transfer or the speed at which work will materialise. A safe, confidential space helps those concerns surface before they become disengagement or underperformance.
Confirm the commercial case before day one.
Assign a sponsor with defined responsibilities.
Plan internal and client introductions early.
Provide confidential support outside reporting lines.
Review progress against the original business plan.
IntoGreat Coaching Limited's position aligns with this approach: integration is the final step in recruitment, not a standalone coaching programme detached from the hire's commercial purpose.
A lateral partner should feel expected, supported and commercially relevant from the outset, because the recruitment investment is still being made after the signature.
Build the conditions before the partner arrives
Strong integration starts well before the first week. Effective firms use due diligence to design practical support, rather than waiting to see whether the partner finds their own way.
Turn due diligence into a plan
Roger Bull described Burges Salmon's focus on understanding a lateral partner's business plan in advance. That allows the firm to identify who the partner needs to meet, what support is required and where the strongest adjacencies sit.
Map relationships, not just offices
Multi-office firms need deliberate cross-office integration. If a lateral joins in London, Bristol or Edinburgh, for example, the plan must still connect them with the right teams, junior lawyers, sector specialists and client relationship partners.
Bring business services in early
A lateral hired to grow a less mature practice area may need marketing support, market-facing activity, event planning or sector positioning from day one. Business services should be part of the integration design, not a later rescue team.
Identify priority internal relationships.
Agree first six-month market activity.
Clarify client introduction responsibilities.
Plan cross-office working opportunities.
Set review points before arrival.
This planning gives the lateral a practical route into the firm and gives leadership a clearer basis for judging whether the original recruitment case is being supported properly.
Preparation reduces avoidable friction, particularly where a partner has moved for strategic growth rather than simply to continue an existing book of work.
Use leadership habits that make integration practical
Integration succeeds through behaviour as much as process. Listening, accountability and timely intervention turn a written plan into a working partnership between the lateral and the firm.
Listening makes strategy usable
Burges Salmon's strategy process included around 25 listening sessions across the firm, followed by partner engagement, town halls and team-level discussions. The lesson for integration is direct: people commit more readily to a plan they have helped to understand and apply.
Sponsorship needs accountability
A sponsoring partner should not disappear once the recruit arrives. Regular check-ins with the sponsor help confirm whether promised introductions, client opportunities and internal positioning are happening in practice.
AI does not replace client curiosity
Bull was optimistic about AI as a research and analysis tool, but linked success to enduring partner skills: understanding clients, asking better questions and applying judgement. Lateral partners need the same combination of tools, curiosity and relationship-building support.
What introductions have been completed?
Which client opportunities need acceleration?
Where is the partner blocked internally?
What support is needed centrally?
What has changed since the business case?
These questions keep the tone collaborative rather than punitive. They also make it harder for early warning signs to be missed until the partner is already detached.
Leadership habits matter because integration is a live management responsibility, not a document saved at the end of recruitment.
Protect the commercial return after day one
The commercial return on a lateral hire depends on sustained attention. Senior leaders should look beyond arrival logistics and test whether the partner is becoming productive, connected and confident.
Client focus sharpens recruitment choices
Bull emphasised client curiosity as central to partner success. For lateral hiring, that means understanding which clients value the recruit's expertise, where relationships may develop and what the market genuinely needs from the practice.
Market disruption creates opportunity and risk
US and UK law firm mergers can create pressure around rates, client fit and partner comfort. That may open recruitment opportunities, but it also increases the need to test cultural alignment and support partners through a major change of environment.
Learn when a hire underperforms
If a lateral does not progress as hoped, firms should review what happened rather than treating the outcome as the individual's failure alone. The useful question is what recruitment, sponsorship and integration should do differently next time.
Few meaningful internal referrals.
Delayed client introductions.
Unclear practice positioning.
Sponsor disengagement.
Private concerns left unspoken.
These signs do not prove failure, but they justify early intervention. A measured review protects the individual, the sponsor and the firm's wider recruitment strategy.
The return on lateral hiring improves when firms manage integration as a commercial discipline with shared responsibility and clear ownership.
Conclusion
Lateral partner integration is not a courtesy after recruitment. It is the mechanism that helps a major hiring investment become performance, retention and client value.
First, ownership matters. Recruitment should remain involved because the business case, sponsor commitments and expected return were created before the partner joined.
Second, preparation must start early. Due diligence, relationship mapping and business services support give the lateral a clearer route into the firm.
Third, leadership behaviour determines whether the plan works. Listening, sponsor accountability and confidential support help partners raise concerns before momentum is lost.
For senior law firm leaders, the practical step is simple: review the last lateral hire and ask whether integration was managed as the final stage of recruitment or left to chance.
