Short answer. Yes — four equal parts, but of the hereditary estate rather than of everything in her name. Article 980 provides that the children of the deceased shall always inherit from him in their own right, dividing the inheritance in equal shares. Debts come out first.

Civil Code, Article 980 — Children Inherit in Their Own Right. Read the full provision →

Always, and in equal shares

The provision leaves no discretion: the children of the deceased shall always inherit from him in their own right, dividing the inheritance in equal shares. Four children, four equal parts. The word always is doing real work — the division does not bend for the child who cared for the mother in her last years, the one who lives abroad and never visited, the one who already owns a house, or the one the family privately regards as having taken enough already. If a parent wants a different distribution, the instrument for that is a will, and even a will cannot cut into the legitime.

"In their own right" is not filler

Inheriting in their own right means each child takes as a child, personally, and the estate is counted by heads at that level. It is set against the other way of inheriting, by right of representation, where descendants of a child who died before the parent step into their parent's place and share the one portion that would have been his. So the four equal parts assume four living children. If one of the four had died leaving children of her own, the estate would still be divided into four, but her quarter would go to her children between them rather than being redistributed among the surviving three.

What exactly is being quartered

The inheritance is the net estate, not the gross list of assets. Debts, taxes and the expenses of the last illness and the funeral are settled first, and where the mother was married, the property regime of the marriage has to be liquidated before anything is divided — the surviving husband's own half of the community property is his already and is not part of what the children split. Only the balance is quartered. Working the other way round, dividing the visible assets and settling the debts afterwards, is how partitions end up being unwound years later.

If the father is also alive

The number of parts changes when a spouse survives. A surviving husband or wife inherits together with the children rather than after them, taking a share equal to that of one legitimate child, so an estate with four children and a surviving spouse divides into five parts rather than four. Establish the status of the marriage at the date of death before doing any arithmetic. The other point to settle early is who the children are: an illegitimate child of the deceased is also an heir, on a different fraction, and a settlement that leaves one out is vulnerable long after it is signed.
