Conveyance and other dealings by registered owner. An owner of registered land may convey, mortgage, lease, charge or otherwise deal with the same in accordance with existing laws. He may use such forms of deeds, mortgages, leases or other voluntary instruments as are sufficient in law. But no deed, mortgage, lease, or other voluntary instrument, except a will purporting to convey or affect registered land shall take effect as a conveyance or bind the land, but shall operate only as a contract between the parties and as evidence of authority to the Register of Deeds to make registration.

The act of registration shall be the operative act to convey or affect the land insofar as third persons are concerned, and in all cases under this Decree, the registration shall be made in the office of the Register of Deeds for the province or city where the land lies.
