Short answer. Yes, possibly. Rule 74, Section 5 of the Rules of Court gives a person who was still a minor when the two-year period expired a further year to present a claim — counted not from the partition, but from the day the disability is removed, that is, from reaching the age of majority.
What the law says
If on the date of the expiration of the period of two years prescribed in the preceding section the person authorized to file a claim is a minor or mentally incapacitated, or is in prison or outside the Philippines, he may present his claim within one year after such disability is removed.

The two-year bar does not run against a minor
Rule 74, Section 5 answers this squarely. If, on the date the two-year period expired, the person authorized to file a claim is a minor or mentally incapacitated, or is in prison or outside the Philippines, that person may present his claim within one year after such disability is removed. The rule recognises that a child cannot be expected to police a partition made by adults around him. Your minority did not erase your share of the estate; it postponed the deadline for asserting it, and gave you a personal window of your own once you could finally act.
When your one-year window opens and closes
For a minor, the disability is removed on reaching the age of majority, and from that day you have one year to present your claim. The same extension covers the three other situations the rule names — mental incapacity, imprisonment, and absence from the Philippines — each ending when the incapacity lifts, the prisoner is released, or the absentee returns. What matters is your status on the date of the expiration of the period of two years: the extension protects only someone still under a disability at that precise point. If you had already come of age before the two years ran out, this particular rule does not lengthen your time.
What you will need to establish
Two sets of dates decide everything. First, when the two-year period began and ended — that turns on the settlement your relatives executed, so obtain a copy of the deed of extrajudicial settlement or partition and any annotation or registration details that fix its date. Second, your own birth date, proved by your birth certificate, to show you were still a minor when the period lapsed and to compute the day your one-year window opened. Expect also to prove your relationship to the deceased, since the rule speaks of a person authorized to file a claim — you must be someone with a genuine interest in the estate, such as an heir who was left out of the division.
Count carefully before giving up
Do the arithmetic before assuming the claim is lost. The two years must first have fully run, and only then does your personal one-year period start; a miscount at either step changes the answer entirely. If the extended window is still open, act within it rather than wait on a family accommodation that may never come. If both periods genuinely appear to have lapsed, the position becomes harder and depends on facts beyond the rule quoted here — for instance, how the settlement was actually carried out and who took part in it. That assessment is worth a lawyer's review of the deed, the dates, and your birth records.
