I guess it depends on the form of  the business entity; what is the form of  the business entity? Is it an S corp??? C corp??

I assume that your entity is an S corp, THEN,  If you intend to sell your shares to a third party, check with a lawyer to make sure the buyer won't cause the company to lose its S corp status.

There are legal restrictions on who can own shares of an S corp. If you plan to sell your shares back to the company instead, be careful:

Most states require a corp to meet certain financial requirements before it can legally redeem or purchase a shareholder's shares..

For instance, if the corporation can't pay its debts after it buys you out, the corporation (and its creditors) could come after you for that money

You should be able to handle the basics of your departure yourself, without the assistance of a lawyer.

But if you're ending your relationship with the corporation because of its shaky or questionable business practices, give your lawyer a jingle.

You and your lawyer should look closely at the company's debts and liabilities to see whether they could leap out of the past and bite you.
