Working in-house: what really changes from private practice and how to prepare the move to a company legal department

In-house lawyering is having a good moment: legal departments are getting involved earlier in business decisions and their weight inside companies is growing, as the ICAM dean and board member Ana Buitrago highlighted this very week at the opening of the III In-House Lawyering Meeting ICAM-ICAB. For many law firm lawyers, moving in-house is the natural next step. But it is not more of the same on a different schedule: it is a different way of practising the profession.

What actually changes

The first difference is the client: just one, internal and permanent. Gone is the ability to spread risk across dozens of other people's matters; your success is tied to a single organisation, with its cycles and its crises. The second is timing: at a firm you work against procedural or closing deadlines; in a company, against the rhythms of the business, which are less formal but no less demanding, and often require answers in hours, not weeks. The third is depth: the in-house lawyer ends up knowing one sector and one company like nobody else, at the cost of losing the variety of matters that external practice provides.

And a fourth, less visible one: how merit is measured. At a firm you bill; in a company, you prevent. The in-house lawyer's value is measured by problems that never happened, contracts that never went to court and well-informed decisions, which makes performance harder to demonstrate and forces you to learn to make it visible.

What legal departments look for when hiring

Selection processes for legal departments reward three things that do not always match the classic law firm CV. The first is solution orientation: knowing how to answer "how it can be done" before "why it cannot", while keeping the independence of judgement Dean Ribón called for this week: "Being a good lawyer does not mean always giving the answer our client expects to hear, but the one they need to know". The second is translation ability, as Buitrago put it: "There is little point in knowing all the risks of a transaction if we cannot convey them to those who must make the decisions". The third is vendor management: much of in-house work is selecting, briefing and supervising external firms, something best learned having been on the other side.

How to prepare the move from a firm

The years before the move matter more than the interview. Three useful moves: specialise in the sector you want to jump to (departments hire industry knowledge as much as legal knowledge), seek out recurring work from corporate clients at the firm to learn their internal logic, and build a professional network in the in-house ecosystem, which has its own forums and communities, such as the Aranzadi In-House Lawyering Congress or dedicated bar association spaces.

It is also worth adjusting financial expectations: the salary curve is flatter than at a large firm, with better predictability and, generally, better work-life balance, but a lower ceiling at junior levels. Our study of lawyers' salaries in Spain allows you to compare ranges.

The way back is not closed

The idea that those who leave a firm never return has aged badly: firms increasingly value lawyers with in-house client experience, because they know how legal services are bought from the inside. The key to keeping the door open is not losing the technique: keep training, keep the bar membership active and do not let too many years pass without touching your original practice area.
