The power to mortgage or lease property generally must be expressly given, it will not be implied in a general power to manage the principal's business, neither would an authority to sell, carry with it the power of mortgage.

A power to mortgage property may be implied, however, where it is necessary to carry out the power originally granted, but the claim to such an implied power cannot safely be indulged in, unless there is a close connection between the power so granted, and the necessity of making the mortgage.29 An execution of a lease under seal by the agent in his own name, would not bind the principal, even though it be shown that the agent was in fact the agent of the principal sought to be charged.30 Where the lease to be made is not to be under seal, a parol authority to make the same is sufficient.31 The power to bind the principal for rent, would necessarily be implied as included in the power given where the agent is authorized to conduct a business at a particular place, and where to conduct the business it was necessary to rent a house.32 An agent with authority to lease for one particular period, could not lease for a longer period.33
