Changing law firms: when it makes sense, how to do it well and the limits set by professional conduct

Average tenure at a first firm has shortened considerably: moving every few years is now a normal career path in the legal profession, not an anomaly. But a well-managed exit and a badly managed one leave very different traces in a sector where everyone knows everyone. This guide organizes the decision: when to move, how to do it and which lines must not be crossed.

Signs it is time to consider a change

One bad week is not a sign; a six-month pattern is. The indicators the sector recognizes as legitimate:

• Learning stalled: a year executing the same tasks with no new complexity and no client contact.
• Structural ceiling: the firm has no next stage for you (no promotion track, no opening in the practice you want) or promotion depends on variables you do not control.
• Persistent pay gap: earning clearly below market with no correction after raising it. Reference data is in the report on lawyers' salaries in Spain.
• Values misalignment: practices that clash with professional ethics or an environment that damages health. This signal admits no waiting.

How to search without burning your current position

Searching while employed requires operational discretion: interviews outside working hours and off firm devices, explicit confidentiality with interviewers (asking them not to contact your current firm is standard) and references chosen outside your direct structure. Preparation is the same as for any senior process: a results-oriented CV and interviews with technical tasks, as detailed in the guides to CVs and cover letters for law firms and job interviews at law firms.

Negotiating the exit

With a signed offer in hand, the exit is managed with three rules:

1. Notice and formality: the law firm's special employment relationship has its own regime (Royal Decree 1331/2006); reviewing the contract and respecting the agreed notice is the minimum, and enabling an orderly handover is professional.
2. The conversation: first to your direct supervisor, in person, without ultimatums or accumulated grievances. The exits that are remembered are the clean ones.
3. The counteroffer: if it comes, ask why announcing your departure was needed for it to arrive. Sector statistics are hard on those who accept staying for the counteroffer.

The lines that must not be crossed: clients, information and non-compete

This is where most problems arise. The Code of Conduct and professional secrecy rules draw clear lines: clients belong to the firm, documentation belongs to the firm, and nobody carries confidential information away in their personal email. Contacting clients before the exit to offer your services, downloading files or leaking the move halfway can end in disciplinary proceedings and litigation, as we detailed in lateral hires: professional conduct and non-compete.

The correct practice: clients freely decide who handles their matters once the departure is communicated through the firm's channels, and the departing lawyer cooperates in the orderly handover. Non-compete and non-solicitation covenants, if they exist in the contract, must be reviewed in detail before signing the new incorporation.

Frequent mistakes worth avoiding

• Leaving for a title, not a project: the jump pays off when it structurally improves learning, platform or compensation, not just the label.
• Burning the bridge on the way out: the sector is small; the partner you leave today is tomorrow's client or partner.
• Announcing the move too early: the news spreads on its own; do not let it spread through you.
• Neglecting the financial closing: variable pay, bonuses and pending amounts must be put in writing before the last payslip.

A note on the move in-house

Changing firms is not the only exit: moving to a corporate legal department is the other mainstream route, with its own rules. You gain predictable hours and closeness to the business, and you lose technical variety and, in many cases, long-term pay ceiling. The decision is less about salary than about work model, and it is best made with full information: talk to those who have done it, review the corporate market's offers and weigh reversibility, because returning from in-house to a firm is possible, but not automatic.

Changing firms well is another career skill. Those who do it in an orderly way gain reputation at two firms at once: the one they leave and the one that receives them.
