In-house legal teams rarely have a constant workload. They have a baseline, and then they have spikes: a financing round, an acquisition, a regulatory inquiry, a product launch in a new market. Hiring for the spike leaves you overstaffed the rest of the year. Hiring for the baseline leaves you stretched every time something big happens.
Flexible legal resourcing closes that gap. Instead of adding permanent headcount, you bring in experienced lawyers for a defined period or scope, and they work inside your team, on your matters, to your standards. This guide explains how it works, the four main models, when each one fits, and how the cost compares with hiring.
What is flexible legal resourcing?
Flexible legal resourcing means using lawyers who are not permanent employees to cover work your in-house team can’t absorb. The lawyers are usually experienced, often ex-big-law or ex-in-house, and they choose project-based work. A provider vets them, matches them to your needs and handles the contract, so you get a lawyer without running a recruitment process.
It differs from instructing a law firm in two ways. The lawyer works as part of your team rather than as outside counsel advising on a matter, and you pay for capacity, by the day, the month or the project, rather than for hours billed at law firm rates.
The four models
Most flexible arrangements fall into one of four models. Many legal departments use more than one at the same time.
Secondment or interim lawyer
A lawyer joins your team full-time for a fixed period, typically three to twelve months. This is the model for parental leave cover, a senior departure, or a long project such as a system migration or a large contract remediation. The lawyer sits in your team, attends your meetings and works on your systems, like a permanent hire on a fixed-term contract.
Fractional or part-time counsel
An experienced lawyer works for you a set number of days a week or month. Startups and scale-ups use fractional general counsel when they need senior judgment but can’t justify a full-time GC salary. Larger teams use the same model for a specialist, for example a privacy or employment lawyer, two days a week.
Project-based support
A lawyer or a small team takes on a defined piece of work with a clear end: due diligence for an acquisition, a contract repapering exercise, a regulatory filing, a document review. You agree the scope, the timeline and the team in advance. When the project ends, the engagement ends.
Managed legal services
The provider takes responsibility for a whole function or workflow, such as commercial contracting or NDAs, and runs it to agreed service levels. You stop managing individual lawyers and manage outcomes instead. We cover this model in detail on our managed legal services page.
How the cost compares with hiring
A permanent hire costs more than the salary. You also pay benefits, recruitment fees, onboarding time, equipment and management overhead, and you keep paying through the quiet months. A flexible lawyer costs more per day than an employee on the same salary, but you only pay for the days you use, and there’s no recruitment fee, notice period or severance at the end.
The comparison usually favors flexible resourcing when the need is temporary, uneven or specialist, and favors hiring when the work is steady, full-time and core to the business for years ahead. Compared with outside counsel, a flexible lawyer is typically far cheaper for the same work, because you’re paying for a lawyer’s time without a law firm’s overheads and leverage model.
How onboarding works
Speed is the main reason in-house teams use flexible lawyers, so the process is built to be short. You describe the need: the work, the jurisdiction, the seniority and the timeline. The provider proposes vetted lawyers who match it, and you interview them as you would any candidate. Once you choose, the lawyer gets access to your systems and starts, often within days.
LawFlex matches vetted lawyers to a brief within 24 hours for urgent matters, from a network of more than 2,500 lawyers across 50+ jurisdictions.

FAQ
What is flexible legal resourcing?
It’s the use of experienced lawyers who aren’t permanent employees to cover in-house legal work, on a temporary, part-time or project basis. A provider vets and contracts the lawyers, and they work as part of your team.
How much do on-demand lawyers cost?
Rates depend on seniority, specialism, jurisdiction and the length of the engagement. Most providers charge a daily or monthly rate, which is usually well below what a law firm charges for the same lawyer’s time, with no recruitment fee or long-term commitment.
What is the difference between flexible legal staffing and legal process outsourcing?
Flexible staffing gives you a lawyer who works inside your team under your direction. Legal process outsourcing hands a defined task, such as document review, to an outside team that delivers the output. Many legal departments use both.
How fast can a flexible lawyer start?
With an established provider, you can usually interview matched candidates within a day or two of sending a brief, and a lawyer can start within days. Longer secondments may take a little more time to set up access and equipment.
