Short answer. No — with one exception. A donation to your spouse alone is not collated from your share. But if your parent gave the gift to both of you jointly, you must bring half of the donated property to collation when you inherit.
What the law says
Neither shall donations to the spouse of the child be brought to collation; but if they have been given by the parent to the spouses jointly, the child shall be obliged to bring to collation one-half of the thing donated.

The basic rule: gifts to your spouse are not yours to collate
Collation is the process of adding back to the estate the value of donations a parent gave to a child during the parent's lifetime, so that the estate can be divided fairly among all heirs. Article 1066 of the Civil Code addresses a specific question: what if the parent gave the gift to the child's spouse, not to the child? The answer is clear — donations to the spouse of the child are not subject to collation. The gift went to a different person. You did not receive it, so it is not deducted from your share.
The exception: joint donations to both spouses
If the parent made the donation to both spouses together — to you and your spouse jointly — the calculation changes. Article 1066 provides that in that scenario, "the child shall be obliged to bring to collation one-half of the thing donated." The reasoning is that you received half of the joint donation, even though it was shared with your spouse. That half is treated as a donation to you and must be brought back into the computation of your share of the inheritance. The other half, received by your spouse, is not collated.
What collation is and why it matters
Collation exists to preserve equality among compulsory heirs. If a parent gives gifts to certain children during life — advances on inheritance — the estate division would be unequal if those gifts were simply ignored. Collation adds the value of inter vivos donations back to the estate's notional total so that each heir's share is computed fairly. Article 1066 draws a boundary: gifts to a spouse-in-law are outside this system entirely, unless those gifts were shared jointly with the child heir, in which case only the child's half enters the collation.
Practical implications for estate planning
From a planning standpoint, the structure of a donation — whether it goes to a child, to that child's spouse, or jointly to both — has concrete consequences at inheritance. A donation made solely to a son-in-law or daughter-in-law is legally isolated from the child's inheritance computation. A joint donation to the couple is half-isolated: the spouse's half sits outside collation, but the child's half does not. If precise documentation of the donation's recipients is not kept, disputes among heirs about how to classify the gift are likely to arise during settlement of the estate.
