Subsidiary imprisonment is a personal penalty served by a convict who has no property to pay a fine imposed as part of the sentence. It is not imprisonment for debt (which is prohibited), because it arises from a criminal penalty, not a private obligation. It applies only if the judgment expressly provides for it, or under the conditions the law allows, and it is subject to limits: the subsidiary imprisonment cannot exceed one-third of the term of the principal penalty, and in no case more than one year; it does not apply where the principal penalty is higher than prision correccional; and if the principal penalty is only a fine, the subsidiary imprisonment is limited (for example, up to six months for a grave or less grave offense, and up to fifteen days for a light offense). If the convict later acquires property, they may still be required to pay the fine, notwithstanding the subsidiary imprisonment already served.
What happens if a convict is fined but cannot pay? They may serve subsidiary imprisonment — but only under strict conditions.
What It Is
Subsidiary imprisonment is a personal penalty served by a convict who has no property with which to pay a fine imposed as part of their sentence. In effect, they “serve out” the unpaid fine in jail.
It Is Not Imprisonment for Debt
Although it looks like being jailed for not paying, subsidiary imprisonment is not the prohibited imprisonment for debt. The reason: it arises from a criminal penalty (a fine imposed by a court), not from a private civil obligation. The constitutional ban on imprisonment for debt applies to ordinary contractual debts, not criminal fines.
It Must Be Provided in the Judgment
Subsidiary imprisonment applies only if the judgment expressly provides for it (or under the conditions the law recognizes). A convict cannot be made to serve subsidiary imprisonment if the sentence is silent on it.
The Limits
Several limits protect against excess:
- The subsidiary imprisonment cannot exceed one-third of the term of the principal penalty, and in no case more than one year;
- It does not apply where the principal penalty is higher than prision correccional; and
- If the principal penalty is only a fine, the subsidiary imprisonment is capped (for example, up to six months for a grave or less grave offense, and up to fifteen days for a light offense).
If the Convict Later Has Money
Serving subsidiary imprisonment does not permanently erase the fine. If the convict later acquires property, they may still be required to pay the fine, notwithstanding the subsidiary imprisonment already served.
Practical Takeaways
- Subsidiary imprisonment lets a convict serve out an unpaid fine — it is not imprisonment for debt because it flows from a criminal penalty;
- It applies only if the judgment provides it, and is subject to limits (max one-third of the principal, never over one year, not for penalties above prision correccional);
- Serving it does not extinguish the fine if the convict later acquires property.
