Do I need a lawyer involved before I even start planning a sale?

Not to begin thinking about it — you can start considering timing, talking to your accountant, and forming a general picture without a lawyer involved at all. Where a lawyer earns their place earlier than people expect is once you start taking any action outside your own head: talking to a potential buyer, a broker, a family member with a stake in the business, or even doing preliminary preparation like reorganizing corporate records or contracts.

The nuance is that early legal involvement isn't about drafting a purchase agreement you don't need yet — it's about protecting information and options before you've decided anything. A confidentiality agreement before you share financial details with a prospective buyer, an honest read on what your corporate structure would actually require to sell, or a check on whether a shareholders' agreement or a spouse's interest affects your ability to act alone, are all things worth knowing early rather than discovering midway through a conversation with a buyer.

A useful rule of thumb is to bring a business lawyer in before you share anything meaningful with someone outside your own household or advisors, even if you're nowhere near ready to sign anything. That protects you without committing you to anything.
