Why use an attorney to form my corporation?
Using a business lawyer to form your corporation ensures it will be done correctly and fully completed. This means you know your assets are fully protected and you won't have unpleasant surprises.
The reason to have the corporation in the first place is as an asset protection vehicle. Unfortunately, business owners only find out that they haven't properly formed a corporation (and protected themselves) when they need it most. No one tells you there's a problem until its too late - after a claim against the business has been made.
Assets have to be transferred to the corporation. The shares have to be issued and properly documented. The officers and directors have to know what they need to sign and how to sign to maintain that protection. Of course, the money has to flow properly as well - no commingling.
The key here is that an online form or "corporation formation company" are only selling stationary. Its real world business law advice that is key to making sure you're doing it right.
One simple mistake could cost you thousands more the the several hundred dollar fee to hire an attorney to form your corporation right in the first place.
