Outsourced Legal Department: Pros and Cons

By Christian Steinmetz and Maren Siegels

Short answer: Whether an outsourced legal department pays off depends on volume, confidentiality, the level of control you want and the cost model. There are four options: an outsourced legal department through a law firm retainer or a legal-as-a-service offering, a part-time fractional general counsel, an additional permanent legal counsel, or an interim legal counsel through staff leasing or freelancing. An outsourced legal department fits small, irregular needs; the more ongoing work should stay inside the company and be directed by it, the more an in-house or temporarily integrated lawyer makes sense.

This comparison is for executive boards, CFOs, general counsel and heads of legal in Switzerland and Germany who need to decide how to organise legal work. It sets out the pros and cons of an outsourced legal department, the three alternatives and the criteria for choosing.

Four models at a glance

The four models differ mainly in who directs the work and how it is billed. The table summarises the differences.

Model	Scope	Direction	Cost model	Best suited to
Outsourced legal department (law firm retainer, legal as a service)	Agreed service package or hour budget; requests as needed	The company instructs; the law firm or provider handles matters on its own responsibility	Monthly fee, hour budget or time spent; extra work billed separately	Small, irregular needs without an in-house legal function; external advice and representation
Fractional general counsel	Part-time, fixed days or an hour budget	The company sets the mandate and priorities; the person works with management and teams	Day or hourly rate × agreed scope	A regular need for legal leadership that does not yet justify a full-time role
Additional legal counsel, permanent	Part-time or full-time, open-ended	The company as employer	Salary, employer contributions, recruitment, onboarding	Permanent, predictable demand
Additional legal counsel, interim (staff leasing or freelancing)	Part-time or full-time, fixed term	Staff leasing: the company gives professional instructions; freelancing: independent within the mandate	Day or hourly rate for the agreed capacity	Vacancy, leave cover, peak workload, project or bridging until a permanent hire

The models can be combined. A law firm often handles specialist questions while an in-house or temporarily integrated lawyer covers day-to-day work.

Outsourced legal department: law firm retainer and legal as a service

An outsourced legal department is a model in which a law firm or a legal-as-a-service provider takes on a company's legal work for a fixed fee or hour budget. The company has no legal function of its own or supplements a very small one.

Pros

Access to several areas of law through one point of contact.
Independent advice and, with law firms, representation in court and before authorities.
Predictable base cost with a fixed fee or hour budget.
No recruitment or management effort.

Cons

Less integration into internal processes, systems and decision paths.
Knowledge about the company partly stays outside.
As volume grows, costs rise with every request beyond the budget.
The company still has to prioritise between requests itself.

Before signing, clarify which services the package includes, how extra work is billed and who coordinates the law firm's work internally.

Fractional general counsel: part-time legal leadership

A fractional general counsel leads a company's legal function for an agreed part-time share, for example on fixed days each week. Unlike an outsourced legal department, the person works alongside management and the business and knows their processes.

Typical tasks: prioritising contract requests, organising templates and approvals, coordinating outside counsel, preparing decisions.
Strength: leadership experience in-house without funding a full-time role.
Limit: outside the agreed scope there is no automatic standby. Specialist questions and court representation may still need a law firm.

How a fractional GC differs from a time-limited leadership role is explained in fractional GC or interim head of legal. Details of the model are on the fractional general counsel page.

Additional legal counsel: permanent or interim

An additional legal counsel fits when a legal function already exists and ongoing work should stay inside the company. The choice between a permanent and an interim hire depends on whether the need is lasting or temporary.

Permanent hire

A permanent hire is right when demand is lasting and predictable and knowledge should be built up in the team over the long term. It takes time to recruit and onboard and ties the company in through notice periods.

Interim legal counsel

An interim legal counsel covers a vacancy, an absence, a peak workload or a project. Under staff leasing, the company generally holds the right to give professional instructions and the professional is integrated into the organisation; in Germany this is Arbeitnehmerüberlassung (temporary agency work), in Switzerland Personalverleih (Swiss staff leasing). Under freelancing, the professional delivers independently within the agreed mandate. Alpinum Solutions provides legal counsel under both models, part-time or full-time, at every level from junior to senior. At Alpinum, an experienced profile (3–6 years) under staff leasing costs EUR 720–960 per day in Germany and CHF 800–1,200 per day in Switzerland (excluding VAT, as of 18 October 2026). All ranges are in costs in interim legal and compliance.

Decision criteria: volume, confidentiality, direction, cost

The choice follows from four criteria. Answer them honestly and the result is usually clear.

Volume and regularity: few, irregular requests point to an outsourced legal department. Regular work at a small scale points to a fractional GC. Full, ongoing workload points to an additional legal counsel.
Confidentiality and proximity to the business: the more the work touches internal data, systems and decisions, the more it belongs with an integrated person. For an independent outside view, a law firm remains the right choice.
Direction: if you want to set priorities yourself every day, you need an in-house person or one integrated through staff leasing. If instructing matter by matter is enough, an external model works.
Cost model: fixed fees and hour budgets are predictable as long as volume stays stable. Day rates for agreed capacity are predictable when the scope is fixed. A permanent hire pays off when demand is lasting.

Checklist: six questions before you decide

How many legal requests come in each month, and how evenly?
What share is routine, and what needs specialist knowledge or representation?
Who sets priorities today, and who should do so in future?
Which internal systems and data does the legal function need to use?
What does outside counsel cost today, and how is that developing?
Is the need permanent, or is there a foreseeable end?

A combination is often the most economical: an integrated person for day-to-day work and a law firm for specialist matters. The comparison with a permanent hire is covered in interim lawyer, law firm or permanent hire.

Limits and risks

Not a law firm: Alpinum provides legal professionals and leaders and does not give legal advice as a law firm. Independent advice and court representation remain with law firms.
Professional rules: in Germany, providing legal services in specific matters of others on a self-employed basis requires authorisation (sections 2 and 3 of the Legal Services Act, RDG). If you engage a freelance legal counsel, clarify beforehand how tasks and responsibility are structured. Under German temporary agency work (Arbeitnehmerüberlassung), the leasing provider counts as the employer for professional-law purposes, so admission as in-house counsel (Syndikusrechtsanwalt) for the assignment is ruled out (Federal Court of Justice, judgment of 20 March 2023, AnwZ (Brfg) 12/21). The court decided the case of a law firm as the client; that the same applies to corporate legal departments is a likely but not expressly decided conclusion.
Confidentiality in proceedings: since 1 January 2025, a party to Swiss civil proceedings may refuse to disclose documents from its in-house legal service provided, among other things, that the company is entered in the commercial register, the service is led by a person qualified to practise as a lawyer and the activity would be typical of a lawyer's work (Article 167a of the Civil Procedure Code). Whether this also covers a temporarily integrated professional has not been decided.
Responsibility: in every model the company takes the decisions; roles and authority should be agreed before the start.
Knowledge loss: with external and interim models, knowledge is lost if documentation and handover are missing.

FAQ: outsourced legal department pros and cons

At what size does a company need its own legal department?

There is no fixed size. What matters is the volume and regularity of legal work, the regulatory intensity of the sector and the cost of outside advice. When ongoing requests regularly keep one person busy, or spending on law firms for routine work keeps rising, an in-house legal function pays off. A fractional GC can prepare the transition.

What is an external in-house counsel (externer Justiziar)?

In German-speaking markets, an externer Justiziar is usually a lawyer who acts as the standing first point of contact for legal questions for a company without its own legal department, often on a retainer. The term has no statutory definition. It describes a law firm mandate, not employment within the company.

Can a fractional GC replace an outsourced legal department?

Partly. A fractional GC handles leadership, prioritisation and day-to-day work inside the company and directs outside counsel. Independent opinions, specialist areas and court representation still need a law firm. A combination often makes sense: the fractional GC channels the requests, and the law firm handles selected matters.

Which is cheaper: an outsourced legal department or in-house counsel?

It depends on volume. With few requests, a fixed fee or hour budget is usually cheaper. With regular, full workload, an in-house or temporarily integrated person becomes more economical, because there is no cost per request. Compare your total legal spend over the last twelve months with the budget for an integrated solution.

Can I use an interim legal counsel to test whether a permanent role is justified?

Yes. An interim engagement shows how much legal work actually arises and which profile is needed. Record volume and tasks during the engagement. A move into your team (temp-to-perm) is possible; the terms are agreed in advance.

Next step

Describe your volume, tasks and the level of control you want; the right model follows from that. Selected profiles are usually available within 48 hours; the start date is agreed between the company and Alpinum.
