Transitioning In-House: Seven Common Mistakes Lawyers Make (and How to Avoid Them)
Many attorneys at law firms dream about moving in-house one day. They may want more predictable hours, or work that is closer to the business, or an ability to have a long-term impact on a company.
I’ve made two transitions: moving from Big Law to a publicly traded company; and from a publicly traded company to another one. My first transition was bumpier than expected as in hindsight I misunderstood what the in-house role actually required.
So I sought advice from mentors, spoke with in-house lawyers who had already made the move, and adjusted how I approached the job. My second transition went far smoother.
Below are seven common mistakes lawyers make when moving in-house and how to approach the role more effectively.
1. Mistake: Trying to clear your to-do list like you did at a law firm
At a law firm, the goal is often to finish everything on your list. You respond quickly, work late, and return work product to clients as soon as possible.
When you take that same approach in-house, you set a pace that is impossible to sustain. If you respond instantly to everything, people quickly come to expect it.
Mindset shift. In-house work is different. The tasks to be done are never-ending. Your job is not to complete every task as soon as possible but to prioritize what matters most to the business.
Do this instead:
Pace yourself. Focus on the three most important priorities each day.
Avoid responding late at night unless it is truly urgent.
Expect the unexpected. Urgent priorities often pop up at a moment’s notice and require your immediate attention.
2. Mistake: Being overly risk-averse
Many lawyers arrive in-house believing their role is to identify every possible legal risk and eliminate them all. They highlight every theoretical issue, deliver heavily marked-up contracts, and sometimes default to saying “no.”
Mindset shift. Your role in-house is not simply to identify and eliminate risk but to help the business achieve its objectives while managing risk appropriately. Business leaders rarely expect zero risk but they do expect thoughtful guidance.
Do this instead:
Understand the company’s business objectives and risk tolerance.
Choose your battles. Focus your energy on the risks that truly matter rather than every remote possibility.
Find a way to move forward in a legally compliant way that avoids as much risk as possible.
3. Mistake: Expecting a clear career ladder
Law firms have a well-defined structure: associate to senior associate to partner. Many lawyers expect a similar progression in-house, and end up frustrated when they see progress stall.
Mindset shift. In-house careers rarely follow a straight line. Growth often looks more like a zig-zag than a ladder. Advancement depends less on formal titles and more on how effectively you partner with the business and your colleagues in the legal team.
Do this instead:
Focus on becoming a trusted advisor across the organization.
Success in-house often comes from building strong relationships with stakeholders, helping teams solve problems, and supporting the company’s broader goals.
You succeed by helping others succeed.
4. Mistake: Writing long memos to demonstrate expertise
Law firm training emphasizes thorough analysis and detailed written work. Such training can lead lawyers to write long emails or memos that overwhelm busy business leaders.
Mindset shift. In-house communication should be concise, practical, and actionable. Your client is often a busy leader who wants clarity, not a long memo outlining every theoretical possibility.
Do this instead:
Always consider the audience. Someone from the business team may want a quick summary. Another member of the legal team may want more detail.
Use a simple structure to communicate: First, the key conclusion; second, supporting details if needed; and third, the clear task.
When in doubt, aim for clarity and brevity. If your non-lawyer neighbor could understand the email, then you are probably on the right track.
5. Mistake: Focusing only on hours worked and your work product
Success in law firms often depends on billable hours and producing excellent work. Many lawyers assume the same is true in-house.
Mindset shift. Value is measured differently in-house. What matters is how well you work with internal partners across different business units, how you are seen as a thought-partner and problem solver, and how you help further the business’ objectives.
Do this instead:
Invest time in building relationships with key stakeholders.
Schedule one-on-one conversations with colleagues across functions. Ask what keeps them up at night, what excites them about their work, and how the legal team can support them.
Take the time to understand how the products and services work. The more you understand the business, the better advisor you will be.
Communicate often. Communications help deepen relationships.
6. Mistake: Waiting for perfect information before acting
Law firm work often allows time for extensive research and thorough analysis before giving advice. In-house environments move faster.
Mindset shift. Business decisions often need to be made with incomplete information. Waiting for complete certainty can slow the organization down.
Do this instead:
Get comfortable making recommendations with partial information.
Sometimes you will need to move forward with only half of the required data and adjust as more becomes available. Your role is to help the business make thoughtful decisions, even in imperfect conditions.
7. Mistake: Waiting for the call from the business team
Work usually begins in law firms when a client calls with a legal problem. In-house roles require a different response.
Mindset shift. Your job is not just to react to legal problems but to help the business think ahead. The most effective in-house lawyers are proactive partners who help identify risks and opportunities early, before they turn into problems.
Do this instead:
Look for opportunities to engage before legal issues arise.
Treat every conversation, contract, and decision as a chance to think about both risk and growth. Ask questions about where the business is heading, what initiatives may come next, and where legal input may help the team move faster or more confidently.
When you show up early in the process, a legal person becomes a strategic partner rather than someone that slows things down.
Bottom line
The biggest adjustment when moving in-house is to realize that the role is not just about legal work but is also about partnering with the business. When lawyers make that shift, their work becomes more impactful and rewarding.
