CEO Executive AssistantThe relationship between the managing partner and the Chief Operating Officer is the most important delegation relationship in a law firm. When this relationship is working well, the managing partner is freed to focus on strategy, client relationships, and partnership leadership, while the firm’s operational functions perform at a high level under capable COO leadership. When it is not working well, the managing partner remains trapped in operational management, the COO is underutilized or undercut, and the firm loses both strategic leadership capacity and operational excellence simultaneously.
Building this relationship effectively requires deliberate investment from both parties, but particularly from the managing partner, who sets the terms of the delegation through their behavior, communication, and consistent respect for the COO’s authority.
Tip 1: Define the COO’s Authority Scope Explicitly and in Writing
One of the most common COO relationship failures in law firms is ambiguity about what the COO is actually authorized to do without managing partner approval. COOs who are hired with an impressive title but find themselves seeking managing partner approval for routine operational decisions quickly become frustrated and either leave or reduce their expectations to match their actual authority.
When hiring or clarifying the role with an existing COO, the managing partner should invest time in defining the COO’s authority scope explicitly: what decisions does the COO make without managing partner involvement? What spending authority does the COO have? What hiring decisions are within their authority? What vendor decisions do they own? Document these authorities in writing and distribute them to department heads so they understand to whom operational decisions should be brought.
Tip 2: Avoid Undercutting the COO in Front of Staff
One of the most damaging behaviors managing partners engage in without realizing the consequence is overriding or second-guessing COO decisions in front of staff or other leaders. When a department head sees the managing partner override a COO decision, they learn that the COO’s authority is conditional and that the real decision-maker is the managing partner. From that point, they bypass the COO and escalate directly.
When the managing partner disagrees with a COO decision, the appropriate response is a private conversation, not a public override. Even when the managing partner’s judgment is right on the specific issue, the public override destroys the COO’s authority and creates an escalation culture that undermines the delegation structure.
Tip 3: Invest in a Weekly Alignment Meeting
The managing partner and COO should have a structured weekly meeting that keeps them aligned on operational priorities, emerging issues, and decisions requiring managing partner input. This meeting should be consistent, typically 45 to 60 minutes, and should follow a format that efficiently covers the COO’s updates, any decisions the COO needs from the managing partner, and any strategic developments the managing partner wants to ensure the COO is prepared for.
This weekly alignment meeting is the primary information exchange mechanism between strategic leadership and operational management. When it does not happen, communication becomes ad hoc, the managing partner gets pulled into operational detail to fill information gaps, and the COO is less effective because they are not consistently receiving the strategic context they need to make good operational decisions.
Tip 4: Let the COO Lead Operational Meetings
Managing partners who attend every operational meeting send a message that the COO does not really lead operations. The COO should chair and lead all operational meetings: department head meetings, budget reviews, operational planning sessions, and functional performance reviews.
The managing partner’s appropriate operational meeting attendance is limited to: an annual operations strategy review, quarterly business reviews where the managing partner receives an operational performance summary, and specific meetings where the managing partner’s presence is strategically important, such as the first meeting with a new major vendor or an operational meeting addressing a crisis.
For all other operational meetings, the managing partner should receive a summary from the COO rather than attending personally.
Tip 5: Back the COO When Partners Push Back
Law firm partners sometimes resist COO decisions on space allocation, technology requirements, billing policies, or administrative procedures. When a partner goes around the COO and brings an operational grievance directly to the managing partner, the managing partner’s response sends a critical governance signal.
If the managing partner overrides the COO’s decision to appease the partner, they undercut COO authority and encourage future bypassing. If the managing partner redirects the partner back to the COO and indicates confidence in the COO’s decision, they reinforce the delegation structure.
The managing partner should back the COO on operational decisions within the COO’s authority unless the decision was clearly wrong. Backing the COO in the face of partner pressure is one of the most important signals the managing partner can send about the delegation structure’s integrity.
Tip 6: Give the COO Strategic Context Proactively
COOs make better operational decisions when they understand the strategic context for those decisions. A COO who does not know that the firm is planning a new office opening cannot proactively plan the facilities implications. A COO who does not know that a major lateral partner is being pursued cannot prepare the operational integration planning.
The managing partner should proactively share strategic developments with the COO, including information about potential lateral hires, client relationship opportunities that will create operational demands, planned geographic expansions, and technology investments under consideration. This context sharing enables the COO to anticipate operational implications and prepare without waiting to be told when decisions are already made.
Tip 7: Conduct Annual Authority Reviews
Once per year, the managing partner and COO should review the COO’s authority scope and assess whether it should be adjusted. As the firm grows, some decisions that previously required managing partner approval may appropriately be delegated to the COO. As the COO develops their judgment and track record, additional authority expansions may be warranted.
Conversely, if certain operational decisions have produced consistently poor outcomes, the managing partner may need to reinvest in more oversight in those specific areas.
The annual authority review demonstrates that delegation is a dynamic relationship, not a fixed structure, and that the managing partner is investing in continuously optimizing the delegation architecture.

Tip 8: Evaluate the COO on Outcomes, Not Activities
The managing partner should evaluate the COO’s performance on operational outcomes, not on operational activities. Was the technology platform implemented on time and on budget? Are facilities costs within market range? Are attorneys satisfied with operational services? Are HR processes running effectively?
COOs evaluated on outcomes rather than activities are empowered to make the decisions and investments needed to achieve those outcomes. COOs evaluated on activity compliance, how many meetings they attended, how many reports they filed, become administrators rather than operational leaders.
Tip 9: Invest in the COO’s Professional Development
The COO’s professional development is a delegation investment. A COO who continues to grow in capability can absorb more complex operational challenges and make better decisions across a broader range of situations. The managing partner should ensure the COO has access to professional development: industry conferences, peer networks, executive coaching, and exposure to the strategic dimensions of firm management that help the COO understand the context for operational decisions.
When the COO is developing professionally, the managing partner benefits directly through improved COO performance and expanded delegation capacity.
Tip 10: Maintain the Relationship Through Transition and Conflict
The managing partner-COO relationship will face stress: operational failures, budget overruns, partner complaints, and strategic disagreements. How the managing partner handles these stresses determines whether the relationship remains a genuine partnership or degrades into a managed hierarchy.
In difficult situations, the managing partner should address issues with the COO directly and privately, maintain confidence in the COO’s overall capability while addressing specific failures, and avoid patterns of blame that erode the COO’s willingness to take initiative.
The managing partner who treats the COO as a genuine partner through difficult situations builds a relationship that is resilient, honest, and productive. This relationship is the operational backbone of every delegation system the firm builds.
See law firm delegation for a comprehensive framework that situates the COO relationship within the broader delegation and governance architecture of effective law firm leadership.
The managing partner who invests in building a genuine partnership with a strong COO multiplies their own effectiveness dramatically. The combined capacity of a strategic managing partner and a strong operational COO working in genuine alignment is far greater than the sum of their individual capabilities. Building this relationship well is one of the highest-return investments a managing partner can make.
