Short answer. No. Article 499 says partition shall not prejudice third persons, who keep the rights of mortgage, servitude or any other real right they held before the division. The bank's security survives the split intact, and personal rights against the co-ownership remain in force as well.
What the law says
The partition of a thing owned in common shall not prejudice third persons, who shall retain the rights of mortgage, servitude or any other real rights belonging to them before the division was made.

Partition is an arrangement among owners only
What a partition does is convert each co-owner's undivided share into a definite portion. It settles who owns which part as between the co-owners; it is not a transaction with anyone else and cannot bind anyone who was not part of it. A creditor holding a real right over the property took that right against the thing, not against a share in an abstraction, and the co-owners cannot improve their position against him by agreeing among themselves on new boundaries. The article states the obvious consequence, but it is one people are regularly surprised by.
What this means in practice for the mortgage
The security does not shrink to the portion allotted to the co-owner who granted it, and a co-owner who receives a clean-looking lot does not receive it clean. Nor does the encumbrance vanish because a new title issues on partition — annotations carry across, and a mortgage that was properly registered stays enforceable against the property it originally covered. The point matters most where a mortgage was constituted by one co-owner over the whole thing: partition does not retroactively confine it to his share, and the other co-owners' remedy lies against him, not against the bank.
The rule is not confined to mortgages
The article covers any other real rights and then adds personal rights separately. So a right of way, a right to draw water, a usufruct, a registered lease and a creditor's ordinary claim against the co-ownership all survive the division. A co-owner allotted the portion the servitude runs across takes it subject to the burden even if the partition papers say nothing about it, which is why the encumbrances existing over the whole property are worth listing before, not after, the shares are drawn up.
Deal with the encumbrance in the partition itself
Since it will survive whatever you agree, the sensible course is to price it in. Pull a current certified copy of the title and read every annotation on it, together with the instrument each annotation refers to. Where one co-owner created the burden, the partition can allot that portion to him or provide for how the others are made whole if the creditor comes against their land. And where the creditor's cooperation would actually release part of the property, that is a conversation to have with him before the division is signed.
