Law Is Not Math — Except When It Is

Outcomes are not math. Competent litigation work often is.

I often tell clients that law is not math.

When a client asks, “What is going to happen in my case?” the honest answer is usually: “I can give you my best judgment, but I cannot guarantee the result.”

Litigation is not two plus two equals four. There is a lawyer on the other side. There are disputed facts, imperfect documents, witnesses with memories, judges with discretion, procedural rules, insurance issues, credibility issues, and opposing counsel looking for every possible argument.

That is why litigation exists.

But there is another sense in which law is math.

The work required to handle a case properly is often measurable. If a construction-defect claim requires document review, fact investigation, presuit notice, insurance analysis, party identification, legal research, pleading analysis, evidence preservation, expert coordination, and eventually discovery and motion practice, those tasks do not disappear because the client hired a solo lawyer instead of a large firm.

The work is the work.

A lawyer either performs the necessary tasks competently or does not. The lawyer either identifies the right parties, preserves the right claims, follows the rules, meets the deadlines, develops the evidence, and makes the best lawful arguments — or does not.

That part is much closer to arithmetic.

If the case requires 60 hours of professional work to handle a phase correctly, then it requires 60 hours. It may be 60 hours performed by a partner, two associates, and a paralegal at a large firm. Or it may be 60 hours performed primarily by one experienced lawyer at a smaller firm.

The staffing model may change. The hourly rate may change. The overhead may change.

But the work itself does not become 10% of the work simply because the client hired a solo senior litigator.

The threshold question is competence

The threshold question is not whether the lawyer has a large office, a marble lobby, or a dozen associates.

The threshold question is whether the client trusts the lawyer to handle the matter competently.

If the answer is no, the client should hire someone else. Hire the large firm. Hire the boutique. Hire the contingency firm. Hire whoever the client believes can do the job.

But if the answer is yes — if the client believes the lawyer has the experience, judgment, skill, and discipline to handle the matter properly — then the client should expect to fund the work at a professional level.

A serious commercial litigation matter does not become a small matter because the lawyer works in a smaller setting.

A condominium association pursuing an $800,000 or $1 million construction-defect claim still has an $800,000 or $1 million construction-defect claim. If the case involves multiple potential responsible parties, insurance issues, engineering issues, presuit statutory requirements, permitting issues, and disputed facts, those issues must be handled.

They do not disappear because the client hired a smaller firm.

A smaller firm can be a better value. It is not a magic coupon.

An experienced solo litigator can often be less expensive than a large firm. Sometimes significantly less expensive.

The client is not paying for multiple lawyers to attend internal conferences. The client is not paying for associate training. The client is not paying for large-firm overhead. The client may get direct access to the lawyer actually responsible for the strategy, judgment, writing, and advocacy.

That can be a very good deal.

But “less expensive than BigLaw” does not mean “nearly free.”

The discount comes from efficiency, experience, lower overhead, and a leaner staffing model. It does not come from pretending the work does not exist.

A serious commercial case does not become a fast-food item because the lawyer works in a smaller setting. The client may be getting a better price than the steakhouse across town. But the client is still ordering steak, not a cheeseburger.

That is the point.

If the matter requires 60 hours of legal work, it requires 60 hours of legal work. A large firm may spread those hours across a partner, several associates, and a paralegal. A solo senior litigator may perform most of that work personally. That may save money. It may reduce duplication. It may eliminate large-firm overhead.

But it does not turn a 60-hour litigation project into a 14-hour project.

Clients sometimes want five-star litigation work at McDouble prices. They want the lawyer to find the right claims, name the right parties, preserve the evidence, analyze the insurance, comply with presuit requirements, write excellent motions, meet every deadline, and push the case toward a good result. But they also want to fund it as if the lawyer is selling a fast-food sandwich.

That is not how litigation works.

A smaller firm may give the client a better price than the famous steakhouse. It may even be the smarter purchase. But it is still a steak dinner.

There is no discount version of professional responsibility

A lawyer’s professional obligations do not shrink because the client wants a smaller bill.

A solo lawyer still has to meet deadlines. A solo lawyer still has to research the law. A solo lawyer still has to review the documents. A solo lawyer still has to comply with presuit statutes. A solo lawyer still has to make good-faith factual and legal allegations. A solo lawyer still has to protect the client from procedural mistakes. A solo lawyer still has to prepare the case as if the other side will fight.

There is no discount version of professional responsibility.

The client can choose a narrower scope. The client can choose to handle the case in stages. The client can decide not to pursue a claim. The client can decide the risk or cost is too high.

Those are legitimate business decisions.

But if the client wants the work done, the work has to be done correctly.

And correct work takes time.

A serious case requires a serious budget

Clients are absolutely entitled to make cost-benefit decisions. Not every case should be litigated through trial. Not every claim should be pursued at any cost. Good lawyers should help clients think practically about budget, risk, insurance, collectability, settlement, and proportionality.

But proportionality is not the same thing as wishful thinking.

If a client is pursuing a six-figure or seven-figure claim, the client should expect real legal work. If the matter involves construction defects, insurance, experts, multiple parties, statutory presuit notices, and potential litigation, the client should not be surprised that the case requires more than a few phone calls and a demand letter.

The work can be staged. In many cases, that is the best approach. A client can fund an investigation phase, then a presuit phase, then a pleading phase, then discovery, mediation, motion practice, and trial preparation if necessary.

But each phase still has to be funded at a level that allows the lawyer to do the work correctly.

If the first phase requires document review, chronology development, legal research, insurance analysis, and strategy, then the lawyer has to be paid to perform that work. If the next phase requires formal presuit notices, claim development, communications with insurers, evidence preservation, complaint preparation, and filing, then that phase also has to be funded.

The fact that the lawyer is efficient does not mean the lawyer is working for free.

The fee rules recognize reality

Lawyers’ fees are not supposed to be random numbers pulled out of the air.

The rules governing lawyers’ fees recognize practical factors such as the time and labor required, the novelty and difficulty of the issues, the skill required to perform the work properly, the customary fee for similar work, the amount involved, the responsibility assumed, time limitations, the lawyer’s experience and ability, and the extent to which taking one matter may limit the lawyer’s ability to take other work.

That reflects reality.

A lawyer’s time is finite. If a matter requires 60 hours of focused work, those are 60 hours the lawyer cannot spend on another client’s case. If a matter involves serious damages, complex facts, statutory procedures, insurance, experts, or litigation risk, the responsibility is greater.

The fee should reflect the work, the responsibility, and the skill required.

Better value does not mean bargain basement

This is the real value proposition of the senior solo litigator:

You can often get serious, experienced, partner-level legal work at a lower total cost than a large firm would charge.

That is a meaningful advantage.

But it is not the same as saying the work should cost almost nothing. A senior solo litigator may be cheaper than a large firm. He may be more efficient. He may avoid layers of staffing and overhead. But he is still performing serious legal work, assuming professional responsibility, and taking time away from other matters.

If the client wants the large firm, hire the large firm.

If the client wants the contingency firm, hire the contingency firm.

If the client wants to spend nothing, do nothing.

But if the client hires an experienced lawyer to handle a serious matter, the client should expect to pay for serious legal work.

The bottom line

Law is not math when a client asks a lawyer to predict the result.

No honest lawyer can promise what a judge, jury, arbitrator, opposing party, insurer, witness, or expert will do.

But law is closer to math when we are talking about what competent litigation work requires.

The facts still have to be learned. The documents still have to be reviewed. The law still has to be researched. The claims still have to be preserved. The right parties still have to be identified. The arguments still have to be made. The deadlines still have to be met.

A smaller firm may be less expensive than BigLaw.

It should not be expected to be 90% cheaper while producing the same quality, assuming the same responsibility, and carrying the same professional obligations.

That is not how litigation works.

The work is the work.

And in that sense, law really is math.
