Section 106. Sale of agricultural land; affidavit. No voluntary deed or instrument purporting to be a subdivision, mortgage, lease, sale or any other mode of encumbrance or conveyance of private agricultural land principally devoted to rice or corn or any portion thereof shall be registered unless accompanied by an affidavit of the vendor or executor stating that the land involved is not tenanted, or if tenanted, the same is not primarily devoted to the production of rice and/or corn.
If only a portion of the land is primarily devoted to the production of rice and/or corn, and such area so devoted is tenanted, no such deed or instrument shall be registered unless accompanied by an affidavit stating the area (size) of the portion which is tenanted and primarily devoted to rice and/or corn, and stating further that the deed or instrument covers only the untenanted portion or that which is not primarily devoted to the production of rice and/or corn. A memorandum of said affidavit shall be annotated on the certificate of title. The Register of Deeds shall cause a copy of the registered deed or instrument, together with the affidavit, to be furnished the Department of Agrarian Reform Regional Office where the land is located. The affidavit provided in this section shall not be required in the case of a tenant-farmer who deals with his Certificate of Land Transfer or Emancipation Patent in accordance with law.
