Negotiation for Lawyers: A Practical Skills Guide

Negotiation is one of the few skills that touches almost every area of legal practice, yet it's rarely taught with much rigour. Solicitors learn contract law, procedure and advocacy in detail, but negotiation technique is too often picked up by osmosis — watching a senior colleague, making mistakes on a live deal, or simply doing what feels natural under pressure. That's a gap worth closing, because a solicitor who negotiates well doesn't just win better terms; they close matters faster, avoid unnecessary disputes, and protect the client relationship in the process. This guide sets out a practical framework for preparing a negotiation, choosing between positional and interest-based approaches, recognising the tactics you'll meet across the table, and staying inside the ethical boundaries the SRA expects of every solicitor acting on a client's behalf. If negotiation sits alongside other client-facing skills you're developing, our advocacy fundamentals guide and our wider CPD courses for legal professionals cover the related ground in more depth.

Preparing to negotiate: BATNA, instructions and authority

Most negotiations are won or lost before anyone sits down at the table. Solicitors who walk in under-prepared tend to either concede too much because they don't know their own limits, or hold too rigid a line because they haven't thought through what happens if the deal falls apart. Three things need to be nailed down before you negotiate anything.

Know your BATNA — and theirs

BATNA — your Best Alternative To a Negotiated Agreement — is the single most useful concept in negotiation theory, developed by Roger Fisher and William Ury in their book Getting to Yes. It's simply the answer to: "If this negotiation fails completely, what happens instead?" For a client, that might be walking away and instructing a different supplier, proceeding to litigation, letting a limitation period lapse, or accepting a worse commercial outcome elsewhere. Your BATNA sets your real walk-away point — not an arbitrary number, but the point at which the deal on the table is worse than your next-best option.

Two things follow from this. First, you should never agree to a deal worse than your BATNA — if you would, your BATNA calculation is wrong or you've lost sight of it under pressure. Second, a strong negotiator also tries to estimate the other side's BATNA, because their walk-away point tells you how much room genuinely exists to move. A party with a weak alternative (an urgent cash-flow need, a hard deadline, no realistic fallback) will usually concede more than one with a strong alternative, regardless of how the conversation is framed.

Client instructions and the limits of your authority

A solicitor negotiates on instructions, not on instinct, and the two things every negotiator must clarify before the first exchange are what outcome the client actually wants and what authority you have to commit them to a deal. That means confirming, in terms the client has genuinely understood and ideally in writing: the client's priorities in order (price, timing, risk allocation, confidentiality, and so on aren't usually equally important); the client's real walk-away point, distinct from their opening ambition; and precisely what you can agree without going back to them versus what needs sign-off mid-negotiation.

Getting caught without authority mid-negotiation is one of the most common — and most damaging — errors. It either forces an awkward pause that hands the other side momentum, or tempts a solicitor to agree something they aren't actually authorised to bind the client to. Setting authority limits clearly at the outset, and getting a fast route back to the client for anything outside them, avoids both problems.

Positional versus interest-based negotiation

Most negotiations sit somewhere on a spectrum between two broad styles, and knowing which one you're in — and which one is likely to serve the client better — shapes almost everything else you do at the table.

Positional negotiation is the familiar back-and-forth over stated positions: one side opens high, the other opens low, and the parties trade concessions until they meet somewhere in the middle. It's intuitive, fast to run, and can work well for simple, one-off, purely transactional deals where the parties have no ongoing relationship and the only real variable is price. Its weakness is that it tends to produce worse outcomes on anything more complex, because it locks both sides into defending a number rather than exploring what would actually satisfy them, and it can damage relationships that need to survive the deal — a commercial contract negotiation that turns adversarial rarely produces the smoothest post-signing relationship.

Interest-based negotiation — the model popularised by Getting to Yes — starts from a different question: not "what position is each side taking?" but "what underlying interest is each side actually trying to satisfy?" A landlord's stated position might be "I want a five-year lease"; their underlying interest might be income certainty. A tenant's position might be "I want a two-year break clause"; their interest might be flexibility if the business doesn't grow as expected. Once you separate positions from interests, options open up that a purely positional trade-off would never surface — a longer lease with an early-exit payment mechanism, for example, can satisfy both interests better than either side's opening position.

In practice, most solicitor-led negotiations benefit from an interest-based approach even where the outcome is ultimately expressed positionally — you still need a final number or a final term, but understanding the interests behind each side's stated position tends to get you there faster and with a better deal for the client. Positional bargaining still has its place for straightforward, low-relationship, high-conflict scenarios, but it should be a deliberate choice, not a default.

Tactics to recognise — and how to respond

Negotiation tactics aren't inherently unethical; most are simply pressure techniques designed to move you off your prepared position. Recognising them for what they are is usually enough to neutralise their effect.

The common thread across all of these is preparation: a solicitor who has already worked out their BATNA, their client's priorities and their own authority limits is far harder to move off position with pressure tactics than one who is improvising in the room.

Ethical boundaries: negotiating within the SRA Principles

Negotiation is inherently adversarial to a degree — you are trying to secure the best outcome for your client — but that doesn't suspend your professional obligations. The SRA's Standards and Regulations set out seven Principles that apply to every solicitor at all times, and Principle 5 requires solicitors to act with integrity. That principle is central to negotiation practice specifically, because negotiation is one of the settings where the temptation to blur the line between robust advocacy and misleading conduct is highest.

Acting with integrity in a negotiation doesn't mean disclosing everything or negotiating without any strategic reticence — a solicitor is entitled to decline to reveal their client's bottom line, and controlled disclosure is a normal and legitimate part of negotiation. What it rules out is active deception: stating something you know to be false (about your instructions, your client's position, a fact material to the deal, or your own authority to agree terms), or creating a false impression through conduct rather than words. There is a meaningful difference between not volunteering your client's walk-away figure and telling the other side a number that isn't true — the first is standard practice; the second is a breach of Principle 5 that can also engage Principle 2 (upholding public trust and confidence in the profession) and, in serious cases, Principle 1 (the rule of law and proper administration of justice).

Practical boundaries worth keeping front of mind during any negotiation:

• Never assert authority you don't have — if you haven't been given sign-off to agree a term, say so rather than implying you can bind the client.
• Don't misstate facts to gain advantage, even where the other side hasn't asked a direct question that would expose the misstatement.
• Keep pressure tactics on your own side proportionate — robust advocacy for a client's interests is expected; tactics designed to mislead or exploit the other side's genuine confusion are not.
• Where the other party is unrepresented, take extra care that your conduct doesn't take unfair advantage of their lack of legal knowledge.
• Document material terms and instructions as you go, both to protect the client and to have a clear record if the integrity of the negotiation is later questioned.

Ultimately, the best negotiators in the profession treat integrity not as a constraint on effective negotiation but as part of what makes it effective — a solicitor whose word can be relied on builds a reputation that makes every future negotiation easier, while one who plays fast and loose with the truth finds counterparties increasingly unwilling to deal with them directly.

Bringing it together

Good negotiation technique isn't a single skill so much as a discipline of preparation, judgement and restraint. Know your BATNA and your client's real priorities before you sit down. Choose an interest-based approach wherever the relationship or the complexity of the deal rewards it, and use positional bargaining deliberately rather than by default. Learn to spot the handful of pressure tactics you'll meet again and again, and respond to them calmly rather than reactively. And throughout, keep the SRA Principles — acting with integrity above all — as the boundary that robust advocacy never crosses. These same habits of preparation and clear client communication carry through directly into commercial contract drafting, where the terms you negotiate ultimately have to be captured accurately on the page.

Frequently asked questions

What is BATNA and why does it matter in legal negotiation?

BATNA stands for Best Alternative To a Negotiated Agreement — what happens if the negotiation fails. It matters because it sets your genuine walk-away point: any deal worse than your BATNA should be rejected, and understanding the other side's likely BATNA tells you how much realistic room there is to negotiate.

Is positional or interest-based negotiation better for solicitors?

Neither is universally better. Positional bargaining suits simple, one-off transactions where price is the only real variable. Interest-based negotiation tends to produce better outcomes for more complex matters or where an ongoing relationship needs to survive the deal, because it looks beyond stated positions to what each side actually needs.

Can a solicitor withhold information during a negotiation without breaching the SRA Principles?

Yes. Choosing not to volunteer a client's bottom line or full strategy is normal and legitimate. What breaches Principle 5 (acting with integrity) is actively stating something false or creating a misleading impression — there's a clear line between controlled disclosure and deception.

What should a solicitor do if the other side sets an artificial deadline?

Test whether the deadline is genuine by asking what actually happens if it passes, and avoid agreeing to terms under time pressure that you haven't been able to check against your client's instructions or your own authority to agree them.

Negotiation technique, like advocacy and drafting, is a skill that sharpens with structured practice and honest feedback — not just experience on live files. Learnsignal's CPD courses for legal professionals cover negotiation, client communication and the wider professional conduct rules that shape day-to-day practice, giving you a practical way to build and evidence this skill as part of your ongoing development.
