10.—(1) A person may convey property to himself jointly with another person, and has been capable of doing so—
(a)as respects personal property, including leaseholds, since 12th August 1859; and
(b)as respects freehold land and things in action, since 31st December 1881,
in like manner as he could convey it to a third person.
(2) After the commencement of this paragraph a person may convey land to himself; but in this paragraph “convey” does not include leasing or making a fee farm grant.
(3) Two or more persons (whether or not they are trustees or personal representatives) may convey, and have always been capable of conveying, any property vested in them to any one or more of themselves in like manner as they could convey it to a third person; but if the persons in whose favour the conveyance is made are, by reason of any fiduciary relationship or otherwise, precluded from validly carrying out the transaction, the conveyance is liable to be set aside.
(4) Without prejudice to Article 11, this Article does not affect any rule of law under which a covenant or agreement entered into by a person with himself is unenforceable.
