Section 65
SEC. 65. Whenever a deed or other instrument is filed for the purpose of transferring registered land in trust, or upon any equitable condition or limitation expressed therein, or for the purpose of creating or declaring a trust or other equitable interest in such land without transfer, the particulars of the trust, condition, limitation, or other equitable interest shall not be entered on the certificate; but a memorandum thereof shall be entered by the words "in trust," or "upon condition," or other apt words, and by a reference by number to the instrument authorizing or creating the same. A similar memorandum shall be made upon the duplicate certificate. The register of deeds shall note upon the original instrument creating or declaring the trust or other equitable interest a reference by number to the certificate of title to which it relates, and to the volume and page in the registration book where it is registered. If the instrument creating or declaring a trust or other equitable interest is already recorded in the land register of the Philippine islands, a certified copy may be filed by the register of deeds and registered.
