Choosing Corporate Legal Counsel in Thailand: When to Retain, What the Agreement Should Say

A buyer-side guide — when a business outgrows hiring lawyers case by case, what scope a retainer agreement should define, how to tell whether it is paying for itself, and the questions worth asking a firm before signing.

The question in the wrong order

The question companies ask is "should we retain a lawyer?" — which cannot be answered, because it skips a step.

The answerable question is what has the business already committed itself to? Legal exposure does not scale with revenue. It scales with the number of promises made to other people: to customers, to suppliers, and to employees.

A company with high revenue that sells for cash, delivers immediately, and employs nobody permanently carries less exposure than a smaller one with thirty employees, credit terms with ten suppliers, and a contract template downloaded from the internet.

Three signals that the moment has arrived

One — legal questions are sitting unanswered. If, in a given month, sales or HR had to decide something without being sure it was correct and went with instinct, exposure is accumulating that nobody is counting.

Two — old documents are being used for work that has changed. The template written when the company only sold goods tends to survive into the period when it also sells services, even though the delivery, warranty and ownership clauses do not transfer between the two.

Three — things are arriving with deadlines attached. Demand letters, labour inspector orders, and correspondence from regulators all start their clock on the day they are received, not on the day the company finds a lawyer.

What belongs in the retainer agreement

Agreements that work in practice tend to be short, but they answer four things clearly.

Included scope — stated as categories of work rather than an exhaustive list of everything possible: answering queries, reviewing incoming contracts, issuing correspondence.

The line where separate work begins — drafting a full new agreement, attending off-site negotiations, filings with authorities, and appearing in court. Left unstated, the two sides will discover they disagree in month three.

Named responsibility and response times — a named lead, an agreed channel, and separate windows for routine and urgent matters.

Confidentiality and file return — including what happens when the engagement ends: return of the original file, a status summary of open matters, and revocation of powers of attorney.

Questions worth asking before you sign

Questions that force an answer about method reveal more than asking whether a firm handles a given area.

  • If we send a contract for review today, what happens next — who reads it, and what form does the answer come back in?
  • When a matter becomes litigation, does the team change?
  • Have you worked with businesses like ours, and what tends to go wrong in this kind of business?
  • If you act for another client who becomes our counterparty, how is that handled?

The last question matters more than most companies think, because conflicts of interest tend to surface mid-matter rather than at signature.

Start with three documents, not a full overhaul

Most companies do not need everything reviewed in the first month. The work that pays first is the three document sets used every day.

The template you send to customers, because it is the most repeated document you have — so a single defect is reproduced with every customer.

Employment documents — contracts, work rules, and warning letter templates — because this set decides the outcome of nearly every labour dispute.

How you collect when a customer does not pay, from the form of the demand letter through to the sequence of steps before deciding to sue.

Those three cover most of what sends a mid-sized business to court. Shareholding structure, governance, and investor readiness can wait until the business reaches that point.

Frequently asked questions

Does a small company with no disputes yet need retained counsel?+

Not every company does, and the useful test is not company size — it is how many commitments the business has already made. If you have employees who need work rules, suppliers you deliver to before being paid, or a template contract you send out every month, the business is accumulating exposure whether or not anything has gone wrong yet. A company selling for cash with no permanent staff can usually keep hiring per matter.

How is this different from hiring a lawyer case by case?+

The difference is when the lawyer arrives. Per-matter work starts once the facts are fixed: the contract is signed, the documents that should exist do not, and the only remaining option is to defend what happened. A retainer means someone reads before you sign and answers before you decide, while the options are still open. The two are not substitutes — many companies keep a retainer for day-to-day work and agree litigation separately when a dispute actually arises.

How detailed should the scope of work be?+

Detailed enough that both sides give the same answer to whether a given task is inside or outside it. The disagreements that surface later are few and predictable: whether drafting a new agreement from scratch is routine work or a separate engagement, whether attending negotiations off-site is included, where filings with government authorities sit, and how a matter is counted once it becomes court litigation. Define those four and the rest rarely becomes an issue.

Should response times be written into the agreement?+

Yes, because it is the term a client feels sooner than any other. What can realistically be agreed is the contact channel, a named responsible lawyer, and separate response windows for routine and urgent matters. This matters more than a long list of services: most companies change advisers because they could not reach anyone on the day they needed an answer, not because of the quality of the legal analysis.

How do we tell whether the retainer is paying for itself?+

Workable measures are the number of matters closed before reaching court, the number of contracts amended before signature, and how long trade debt takes to collect compared with the prior year — all of which you can read from your own records. A good adviser will provide a periodic summary, quarterly for instance, showing where the time went. The value of harm that never happened is inherently hard to quantify, and any figure offered for it should be treated with caution.

One firm for everything, or specialists for each area?+

It depends on how much specialist work the business generates. Most companies benefit from one principal firm that holds the whole context and brings in specialists when needed, because re-explaining the business to each new adviser has its own cost. Businesses with heavy specialist demands — patent prosecution, or complex tax litigation — are usually better served by separating those from the start.

External counsel or an in-house lawyer?+

An in-house lawyer understands the business more deeply and is in the room from the start, but one person cannot cover every field, and cannot appear in court for the company without a practising lawyer's licence. External counsel covers more ground and carries matters through to court, but needs more communication from the company's side. Companies often end up with both as they grow, with the in-house role acting as filter and coordinator.

What should be in place before changing advisers?+

Agree the handover terms when you sign, not when you leave. What you should get back is your original file, a list of open matters with their key deadlines, and the powers of attorney that need to be revoked. Written in advance this costs almost nothing; left unwritten it is always awkward.
