Short answer. Yes, it can be cut down, and yes, you generally have to ask. The Civil Code reduces testamentary dispositions that impair the legitime, but it does so on petition of the compulsory heirs, so the reduction is a remedy you must raise, not something the court applies on its own.
What the law says
Testamentary dispositions that impair or diminish the legitime of the compulsory heirs shall be reduced on petition of the same, insofar as they may be inofficious or excessive.
Civil Code, Article 907 — Reduction Of Inofficious Dispositions. Read the full provision →
Your legitime is not the testator's to give away
Philippine law does not give a testator a free hand. A fixed portion of the estate - the legitime - is reserved by law for compulsory heirs: legitimate children and descendants, in their absence legitimate parents and ascendants, the surviving spouse, and illegitimate children. Only what is left after that reserve, the free portion, may be given to whomever the testator pleases. So a will that leaves a large legacy to a friend, a caregiver, a church, or one favoured child is not automatically invalid. It becomes vulnerable only to the extent it reaches into the reserved portion, and the law's response is to trim it rather than to strike the whole will down.
Reduced only to the extent it is inofficious
The remedy is surgical. The disposition is reduced insofar as they may be inofficious or excessive - that is, only by the amount of the overreach. If a legacy exceeds the free portion by a fifth, that fifth comes back to the legitime and the rest of the legacy stands. The recipient does not forfeit everything, and the testator's wishes are respected as far as the law permits. Working out the excess requires the whole estate to be valued and collated, because gifts made during the testator's lifetime are brought into the computation before anyone can say whether what the will gives away was excessive at all.
Why you have to petition for it
The phrase on petition of the same is the practical trap. Reduction is a right belonging to the compulsory heirs, and rights of that kind can be left unexercised. A court settling the estate will not usually recompute a legacy downward simply because it notices a problem; someone entitled to the legitime has to raise it, and raise it in the settlement proceeding where the will is being probated and the estate distributed. An heir who stays silent while the estate is distributed, signs off on a project of partition, or lets the proceeding close without objecting may find that the moment has passed. Speak up in the case, in writing, and on the record.
What to gather, and what this does not fix
Assemble the will, the death certificate, proof of your relationship to the testator, an inventory of the estate with valuations, and evidence of any substantial gifts, advances or transfers made during the testator's lifetime - those often matter more than the will itself. Reduction addresses the size of a gift; it does not answer separate attacks such as forgery, lack of testamentary capacity, or improper execution of the will, which are raised on their own footing. Nor does it apply to someone who is not a compulsory heir. This is general legal information and not advice on your family's estate; given the deadlines that run in settlement proceedings, have the papers reviewed promptly.
