Short answer. Yes, personally. Article 691 requires the consent of all co-owners before an easement can actually be imposed on shared land, so one co-owner's consent alone does not bind the property. But it does bind that co-owner and his successors — he cannot prevent the exercise of the right he agreed to.
What the law says
In order to impose an easement on an undivided tenement, or piece of land, the consent of all the co-owners shall be required.

The easement itself needs everyone's consent
Article 691 states plainly that imposing an easement on an undivided piece of land requires the consent of all the co-owners. One co-owner agreeing does not, by itself, create a valid easement burdening the whole property — the right to use the land in that particular way is not actually established until every last co-owner has given his own consent, however many of them there happen to be.
What happens while some co-owners haven't agreed yet
Where only some of the co-owners have consented, Article 691 says that consent must be held in abeyance until the last co-owner has expressed his own conformity. So a partial consent does not simply lapse or get discarded — it is kept pending, waiting on the remaining co-owners, rather than treated as either a completed grant or a rejected one.
But the consenting co-owner is personally bound
Even though the easement is not yet established against the property as a whole, Article 691 makes clear that consent given by one co-owner separately from the others still binds the grantor and his successors not to prevent the exercise of the right granted. In practical terms, the co-owner who agreed — and anyone who later takes his place, such as an heir or a buyer of his share — cannot turn around and block the other party from exercising the right that co-owner consented to, once the remaining co-owners eventually give their own consent too.
What this means for the party seeking the easement
For someone who has secured one co-owner's consent to use shared land in a particular way, Article 691 offers a partial but real protection: that consenting co-owner cannot later obstruct the exercise of the right, and neither can whoever inherits or buys that co-owner's share. What is still missing is the consent of the other co-owners, which remains necessary before the easement is actually imposed on the property as a whole rather than merely secured against the one co-owner who agreed.
