How much time does a husband have to legally dispute a child's legitimacy?

Short periods, and residence is what sets them

The Code does not give a single deadline; it gives three, and which one applies depends on where the husband is. If he — or in a proper case any of his heirs — resides in the city or municipality where the birth took place or was recorded, the period is one year. If neither he nor, in his default, all of his heirs reside at that place, the period is two years where they are in the Philippines and three years where they are abroad. The logic is about opportunity to know: proximity to the registry is treated as proximity to the fact, so the closer you are, the less time you get.

When the clock starts running

The period runs from knowledge of the birth or its recording in the civil register, not from the birth itself and not from the date suspicion first arose. Two consequences follow. A husband who knew about the birth cannot extend his time by saying he only recently began to doubt paternity; doubt is not the trigger the article names. And registration matters independently of personal knowledge, because the entry in the civil register is a public fact. The distinction is worth pinning down early in any case, since the difference between one date and another is frequently the difference between an action that is available and one that is gone.

The concealment rule, and its sting in the tail

Where the birth was concealed from the husband or his heirs, or was simply unknown to them, the period is counted from discovery or knowledge of the birth — or of the fact of registration — whichever is earlier. That final phrase is the part people miss. It is not a rule that starts the clock when the husband personally learns the truth; it starts it at the earlier of two events, and learning that a registration exists can be enough even where the underlying facts are still unclear to him. Concealment therefore softens the deadline without removing it.

Two hurdles, not one

The deadline sits on top of a separate restriction: the Code allows legitimacy to be impugned only on a closed list of grounds, and a husband must clear both. That combination is what makes this area unforgiving in practice. A man who takes a year to gather scientific evidence may find the ground perfectly good and the action nonetheless out of time, since the period is measured from knowledge of the birth rather than from when the proof was assembled. Anyone considering this should fix three dates first: the birth, its registration, and the day he learnt of either — and take advice on that basis before doing anything else.
