Q. A was able to register a mineral land under TCT No. 1 as early as 1950. After his death, his children B and C inherited it and sold to D. What is the remedy of the State if it chooses to recover it today? (Solved)

1. File a petition for escheat;

2. File an action for reversion which is imprescriptible (Rep v. Animas, 56 SCRA 499);

3. Cannot file any action anymore because the title has become indefeasible;

4. Cannot recover anymore because while A’s title was void, D has acquired it in good faith and for value.
