Short answer. Yes. Contractual support is subject to adjustment whenever modification is necessary due to changes of circumstances manifestly beyond the contemplation of the parties. The figure you signed is not frozen — but the change has to be of that character, not merely inconvenient.
What the law says
contractual support shall be subject to adjustment whenever modification is necessary due to changes of circumstances manifestly beyond the contemplation of the parties.

An exception to the ordinary force of a contract
Contracts are normally binding on their terms, and a party who agreed to pay a sum does not escape it because paying has become harder. Support agreements are treated differently, because they are meant to answer a need over time and both the need and the ability to meet it move. The article therefore builds adjustment into the arrangement itself. It works in both directions: the same sentence that lets a payer ask for a reduction lets a recipient ask for an increase when circumstances change against them.
The threshold is high on purpose
Two words do the limiting. The change must be manifestly beyond what the parties contemplated — obvious rather than arguable — and beyond the contemplation of the parties, meaning something they did not and could not reasonably have priced into the figure when they signed. Ordinary fluctuations in income, a bonus that did not come, expenses that crept up, are the stuff any agreement anticipates. A genuine loss of employment, a disabling illness, a collapse of the business the support was drawn from, are the kind of thing the sentence is aimed at.
Stopping unilaterally is not the remedy
The article says support shall be subject to adjustment; it does not authorise the payer to set a new figure himself. Until the amount is modified, the agreed sum remains due, and arrears accumulated in the meantime do not disappear because the reduction is later granted. This is the mistake that turns a defensible application into a weak one: a payer who simply stopped paying arrives having already breached, and his good faith is the first thing questioned. Pay what you can, tell the other side why, and move promptly.
There is a floor beneath any reduction
Whatever the contract says, the law's own obligation to support the child persists independently of it, and the same article treats only the excess in amount beyond that required for legal support as ordinary property subject to levy. So an adjustment can bring a generous contractual figure down towards what the law requires; it does not release a parent from supporting the child. Bring proof of the change — the termination papers, the medical records, the financial statements — and a realistic account of your current means and the child's actual needs.
