In 2013 Smith signed a lease with Jones for a certain parcel of land. The lease stated that the lease was between Jones and WLS Inc. The signature line provided for signature by WLS Inc. by Smith as president. For 4 years the rent was paid on time with a check from WLS Inc. signed by Smith. Four years later Jones sued Smith for rent unpaid.

Is Smith a principal, agent, both or neither?

Is the principal disclosed, partially disclosed or undisclosed?

Is Smith liable for the rent? Why or why not?

Thanks!
