Quieting of Title

Dear PAO,

I inherited a piece of land in Pampanga, which was acquired by my husband through a free patent application. From the time we acquired that property up to the present, we have been occupying it. Sometime in 1998, I learned that the title to said property was cancelled by virtue of an Affidavit of Self-Adjudication executed by a certain Gina. To obtain an owner's duplicate copy of the title, Gina filed a petition in court alleging that it was lost, although it was not actually lost. Now, said property was again transferred to her son through a Deed of Donation. Are we barred from recovering said property?
