Short answer. Yes, in intestate succession. Where the deceased left no legitimate descendants and no legitimate ascendants, the illegitimate children succeed to the entire estate and divide it equally among themselves. A surviving spouse, if there is one, would share with them, and a valid will can direct the free portion elsewhere.
What the law says
In the absence of legitimate descendants or ascendants, the illegitimate children shall succeed to the entire estate of the deceased.

Why the two absences matter
Illegitimate children are compulsory heirs in every case, but the size of what they take depends on who else is standing. Legitimate children, and in their absence legitimate parents and ascendants, sit ahead of them in the intestate order and reduce their share to a fraction. Remove both of those groups and nothing is left to compete with the illegitimate children in the descending line, so the whole estate is theirs. Absence means absence at the date of death — a legitimate child who died before your father may still be represented by his own children, and a grandchild in that position counts as a legitimate descendant and changes the picture entirely.
How this article reads today
The rule was framed on the classification of children used when the Civil Code took effect in 1950, and it must be read subject to the Family Code. The Family Code provides that the legitime of each illegitimate child is one-half of the legitime of a legitimate child, and that "except for this modification, all other provisions in the Civil Code governing successional rights shall remain in force." It also recognises a single class of illegitimate child, so the older Civil Code labels — natural, acknowledged natural, spurious — no longer put one illegitimate child ahead of another. Where they inherit alone, they share equally, whatever the circumstances of each birth.
What can still cut into the estate
"Entire estate" means what is left after the estate's own obligations. Funeral expenses, the deceased's debts, administration costs and estate tax come off before any heir is paid. A surviving spouse is not an ascendant or descendant and is not removed by this article; she inherits alongside the illegitimate children. If your father left a will, this intestate rule yields to it for the free portion, though the will cannot cut the children below their reserved legitime. And the article confers rights against the estate of the parent only — it does not open the estates of the parent's legitimate relatives, who remain outside the line of intestate succession with an illegitimate child.
Establish filiation before anything is divided
The claim stands or falls on proof of filiation to your father. The usual evidence is a birth certificate in which he participated, a written and signed acknowledgment, an admission of parentage in a public or private document, or open and continuous possession of the status of his child supported by people who can testify to it. A name typed into a birth record without the father's participation is weak standing alone. Collect certified civil registry copies, together with the death certificate and an inventory of assets and liabilities, before any settlement is drafted. If relatives contest your status or have already begun dividing property, book a consultation promptly.
