When a business should use a law firm instead of one lawyer

How to use this guide

The real choice is not firm brand versus individual personality. Compare the delivery model proposed for the actual work: who leads, who performs each task, what can happen at the same time, how decisions are supervised, and what the business pays for coordination.

Define the work before choosing the delivery model

Start with the business event and required outputs. A focused agreement review may need one experienced practitioner. A transaction involving company approvals, tax structuring, employment transfers, intellectual property and regulatory filings may need coordinated specialists. A commercial dispute may begin with one strategist and expand only if proceedings, evidence review or urgent relief become necessary.

List the expected workstreams, earliest fixed dates, document volume, stakeholders and decisions. Mark what must occur sequentially and what may need to run in parallel. This work map is more useful than selecting by firm size alone.

The Companies Act covers company organisation and relationships involving companies, shareholders and directors, as well as mergers, takeovers and business rescue. That breadth illustrates why a “company matter” may contain several distinct tasks, but it does not mean every company question requires a multi-person firm team.

One focused lawyer may be enough

An individual practitioner can be a strong delivery model where:

• one legal specialism clearly owns the task;
• the first deliverable is limited and well defined;
• the document set can be handled by the proposed person and support structure;
• there is no need for simultaneous negotiation, filing and specialist advice;
• the dates allow realistic review by that practitioner; and
• the business wants a direct line to the person exercising judgement.

Examples may include a contained contract review, a focused opinion, negotiation preparation, a discrete company-record question or an early dispute assessment. The suitability still depends on experience, availability, conflicts and the actual scope.

“Individual lawyer” does not necessarily mean a person working without systems or support. A sole or small-practice lawyer may use candidate attorneys, paralegals, counsel, correspondent firms, technical experts or referral relationships. Ask which resources are part of the proposed mandate and which require separate instruction.

A law firm team may fit multi-specialist work

Choose a broader firm team when the legal problem cannot be responsibly separated from several connected disciplines. A corporate transaction may need company, competition, tax, employment, finance or intellectual-property input. A technology contract dispute may combine commercial drafting, data protection, evidence preservation and litigation.

The benefit is access to coordinated specialisms, not simply a greater number of people. Ask the firm to draw a team map showing the lead lawyer, each specialist, the question they own, and the point at which their work is expected to enter.

Without that map, “full-service” may describe the firm generally rather than the resources included in your instruction.

Parallel deadlines may require more capacity

A team can be useful when several tasks must progress at once: reviewing a large record, preparing affidavits, negotiating interim arrangements, responding to a regulator, preserving evidence and advising business operations.

Test the claimed capacity. Ask how many workstreams can genuinely run in parallel, who is available, what depends on the lead lawyer, and where duplication will be controlled. Adding people late can increase orientation time and inconsistent drafting if the matter record and decision authority are unclear.

One capable lawyer may still coordinate external support effectively. The key question is whether the proposed structure can meet the actual concurrency and volume without compromising supervision.

Continuity can justify a wider bench

Long-running or high-dependency matters need a plan for leave, illness, conflicting hearings, staff changes and peaks in document work. A law firm may offer internal cover, shared records and established handover practices.

Do not assume continuity from headcount. Ask who can step in, whether that person already understands the matter, how the authoritative file is maintained, and which decisions remain reserved for the lead lawyer.

An individual practitioner may provide continuity through a documented cover or referral arrangement. Ask how urgent access and client records would be handled if the practitioner became unavailable.

Supervision and role separation may matter

Some businesses want senior judgement separated from high-volume review, project administration or routine drafting. A team can allocate work at different experience levels while keeping supervision visible.

Ask which tasks the lead lawyer will personally perform, which may be delegated, how delegated work is checked, and how the staffing model affects fees. Do not assume that lower-cost delegation is automatically efficient; unclear instructions or repeated review can erase the saving.

The LPC’s current Code of Conduct applies to legal practitioners, candidate legal practitioners and defined juristic entities. The regulatory framework does not remove the need for the client to understand the people and supervision attached to its own mandate.

More people can introduce coordination cost

A larger team may create additional meetings, internal communication, repeated reading and multiple billing roles. That cost can be justified where the work is genuinely parallel or specialist. It is harder to justify where several people attend without owning distinct tasks.

Ask for a coordination design:

• one client-side decision-maker and one lead legal contact;
• a clear owner for every workstream;
• a shared chronology and document index;
• a method for recording assumptions and instructions;
• rules for internal attendance and status reporting; and
• a review point before the team expands.

The business should know whether it is buying broader capacity, specialist input or simply more layers.

Use a hybrid model when the matter may expand

A practical alternative is to instruct one lead commercial lawyer for the initial classification and add specialists only at defined triggers. For example, employment input may enter if a transaction affects staff, privacy expertise if personal-information handling becomes material, or litigation capability if negotiation fails.

The lead should explain who selects and coordinates additional specialists, whether they are inside or outside the firm, how conflicts and confidentiality are managed, and who approves added scope.

A hybrid model can control early cost without forcing a complex matter through one person. It can also fail if the lead lacks authority, the specialist enters too late, or the handoff requires the business to repeat the file. Record the trigger and responsibility in advance.

Apply six capacity tests

Use the same six tests for an individual practitioner and a firm team:

1. Specialisms: How many distinct legal questions are already visible?
2. Concurrency: Which tasks must progress at the same time?
3. Volume: How much evidence, drafting and stakeholder coordination is expected?
4. Continuity: What happens if the lead person is unavailable?
5. Supervision: Who exercises judgement and checks delegated work?
6. Expansion: How will new expertise be added, approved and priced?

Score the proposed structure, not the theoretical maximum capacity of the provider. A large firm that assigns one unavailable person may offer less usable capacity than a well-organised small practice. A solo specialist with no credible cover may be unsuitable for a matter dependent on continuous urgent access.

Compare equivalent first phases

Give both models the same problem statement and ask for the same first deliverable. Compare who will do the work, estimated effort, assumptions, exclusions, handoffs, disbursements and scope-change process.

A team proposal may cost more because it includes specialist review or parallel preparation. An individual proposal may be lower because it excludes those components or expects later referral. Neither figure is meaningful until the work is aligned.

Ask what the business would need to manage itself. Some models require the client to coordinate several advisers; others place that function with a lead firm. Include internal management time and decision complexity in the comparison.

Make a short delivery-model decision

Record:

• the contained or multi-workstream nature of the matter;
• the expected specialists and parallel tasks;
• the proposed lead and support roles;
• continuity and supervision arrangements;
• the first-phase output and expansion triggers; and
• why the chosen model is proportionate to current facts.

Review the decision when the matter changes. A focused instruction can expand into litigation or a transaction; a complex enquiry may narrow after the first assessment. The delivery model should follow the work rather than becoming permanent because of the original booking.
