Maryland law does not require that a sole member limited liability company (“LLC”) have an existing, enforceable operating agreement on file. Nevertheless, there is an excellent reason to draft and execute one: by executing an LLC operating agreement, the single member of the LLC has drawn a line of protection guarding that person against personal liability for the business debts and obligations of the LLC.

Specifically, Maryland courts have held that the protection from liability that exists by virtue of the LLC’s formation can disintegrate if the LLC fails to observe certain corporate formalities. One of these formalities is the existence of a valid operating agreement. Having an operating agreement in place can protect the single member from liability when a third party attempts to sue the individual member in order to satisfy an obligation resulting from a debt of the LLC.

Without an operating agreement, it may prove more difficult for the sole member to avoid liability. Courts sometimes blur the line between a sole member LLC with its protection from liability for its individual owners, and a sole proprietorship where such protection does not exist. However, this line becomes more clear cut, and courts will as a result hesitate to “pierce the corporate veil” and hold an individual liable for the LLC’s debts, when corporate formalities like having an operating agreement are complied with.
