What is a Free Patent?
A free patent is issued where the applicant is a natural-born Filipino citizen; is not the owner of more than twelve (12) hectares of land; has continuously occupied and cultivated, either by himself or through his predecessors-in-interest, a tract or tracts of agricultural public land subject to disposition, for at least 30 years prior to the effectivity of Republic Act No. 6940; and has paid the real taxes thereon while the same has not been occupied by any person. Once a patent is registered and the corresponding certificate of title is issued, the land covered thereby ceases to be part of public domain and becomes private property, and the Torrens Title issued pursuant to the patent becomes indefeasible upon the expiration of one year from the date of such issuance. However, a title emanating from a free patent which was secured through fraud does not become indefeasible, precisely because the patent from whence the title sprung is itself void and of no effect whatsoever.
