When a buyer and seller are close to an M&A deal, the easy part is often agreeing that the deal makes sense. The harder part is checking what each side is actually agreeing to. The price may already look settled, but the documents still have to deal with approvals, employee matters, customer contracts, liabilities, licenses, and obligations that may continue after closing.
That is where “What does a mergers and acquisitions lawyer do?” becomes a practical question. The lawyer checks whether the file matches the deal people think they are making. If the buyer expects certain contracts, assets, or software rights, the records need to prove they are really there. If the seller expects a clean exit, the agreement needs to show where future claims stop.
Why early deal terms need care
Many deals start with a short conversation and a rough commercial idea. The parties agree that a sale or acquisition seems possible, then a letter of intent appears. It may be only a few pages, but it can carry real weight. Exclusivity, confidentiality, access to records, price adjustments, and closing conditions often appear before the main agreement exists.
A company working with an m&a lawyer can review those early terms before they become difficult to change. That review does not need to turn the deal cold. It simply helps the client understand which points are harmless, which points need clearer wording, and which points could limit leverage later.
A seller may not want to stop speaking with other buyers too soon. A buyer may need enough access to records before spending more on advisers. A vague adjustment clause may sound minor until the final price changes. These are easier to handle while the deal is still flexible.
What happens during legal due diligence
Legal due diligence is where the buyer checks whether the company is as clean as it looked during talks. The seller may say the business has strong contracts, no serious disputes, clear ownership, and stable customers. The buyer still needs to see the records behind those claims.
What does a mergers and acquisitions lawyer do during this stage? They review the documents that could change the deal. That may include corporate records, customer contracts, vendor agreements, debt, leases, employee files, intellectual property, privacy matters, permits, and required consents.
Small details can matter more than expected. A customer contract may need approval before it transfers. A contractor agreement may leave ownership of work unclear. A lease may restrict assignment. A board approval may be missing.
How the main agreement carries the risk
The purchase agreement is the document everyone ends up caring about when the deal is no longer just talk. It says what the buyer gets, what stays out, how the money moves, and which promises each side is making. If something turns out to be wrong after closing, this is usually the paper people go back to first
A mergers and acquisitions lawyer reads that agreement with the client’s position in mind. Representations and warranties describe the condition of the business. Covenants explain what the parties must do before and after closing. Indemnities set out who covers certain losses. Closing conditions explain what must happen before the transaction finishes.
Buyers usually want protection if hidden problems appear. Sellers usually want limits, exceptions, time caps, and a clear end point for future claims. Both positions can be reasonable. The lawyer’s work is to make sure the terms match the facts, the price, and the amount of risk the client is willing to accept.
Why deal structure changes the outcome
A transaction can be built as an asset purchase, stock purchase, merger, or another structure. This choice affects more than the title of the agreement. It can change liabilities, tax planning, contract consents, employee transfers, approvals, and control after closing.
This is where what a mergers and acquisitions lawyer does goes beyond document review. The lawyer helps the client understand how each route works in practice. A buyer may prefer selected assets to avoid certain liabilities. A seller may prefer selling equity because it can create a cleaner exit. Investors, lenders, accountants, and tax advisers may also affect the final structure.
What needs to happen between signing and closing
Signing does not always finish the deal. Many transactions have a period between signing and closing. During that time, the parties may need financing, board approvals, shareholder approvals, third-party consents, updated schedules, regulatory steps, or closing certificates.
The business also keeps running during that period. That sounds simple, but some ordinary decisions may be restricted before closing. New contracts, hiring, spending, debt, or asset sales may need approval from the other side. A practical closing process usually follows this order:
- List every closing condition and required approval.
- Assign each open item to one responsible person.
- Track consents, certificates, and updated schedules.
- Check whether new facts affect the agreement.
- Confirm final deliverables before money and ownership move.
A lawyer keeps this part organized. They track closing items, prepare approvals, review consent language, update disclosure materials, and watch for facts that may affect the agreement. This work can feel quiet until something is missing. One late consent or unclear condition can delay a deal that everyone thought was nearly done.
The part clients usually remember
M&A legal work is not just about finding problems. It is about knowing which problems matter. Some issues are routine. Some need cleaner wording. Some can be priced, disclosed, or covered by escrow. Others should make the client pause.
That judgment matters because deals don’t leave people careless. A founder may be selling a company built over many years. A buyer may be moving quickly before another bidder appears. Investors may push for more protection. Employees may be waiting for answers. A good lawyer helps the client stay clear-headed without turning every concern into a crisis.
