Pursuant to Article 1194 of the RA Civil Code:
A compulsory portion shall be considered the right of an heir to inherit, regardless of the content of the will, at least the half of the portion which would have been allotted to him in case of succession by law.
At the time of opening the succession, minor children, as well as children, the spouse, and parents of a testator who have been declared as disabled or having no active legal capacity as prescribed by law or have attained the age of 60, shall have the right to compulsory portion.
When determining the amount of compulsory portion, everything that the heir having the right to such portion receives from the succession on any ground, including the value of the testamentary trust established for the benefit of such an heir shall be taken into account.
