Section 57 — Breach of probation conditions
English translation
When the offender fails to comply with the conditions referred to in Section 56, the court may admonish the offender, or may determine the punishment in the case where the court has not yet determined the punishment, or impose the punishment in the case where the court has already determined the punishment but suspended its imposition.

Firm annotation
Section 57 governs what happens when an offender granted suspension under Section 56 breaches the conduct conditions. The court has a graduated set of options rather than an automatic penalty: it may simply admonish the offender; where it had only suspended the determination of punishment, it may now determine the punishment; and where it had fixed the punishment but suspended its imposition, it may now impose that punishment. The provision mirrors the two suspension routes in Section 56 and makes the suspended sentence conditional on compliance. Committing a further offense of the same character is a common trigger for the court to revoke suspension and impose the penalty.
Why this matters in practice
A suspended sentence is not the end of the matter: breaking the conditions, and especially committing a like offense during the supervision period, can bring the suspended imprisonment into effect. The court is not obliged to jail on a first slip, since admonition is an option, but a serious or repeated breach usually leads to imposition of the penalty. Anyone under supervision should keep evidence of reporting and compliance, and get advice quickly if accused of a breach; a Thai lawyer can help respond before the court acts.

Frequently asked questions
What happens if you breach probation conditions in Thailand?
Under Section 57 the court may admonish you, determine the punishment if it was not yet fixed, or impose the punishment if it was fixed but suspended.
Does a breach automatically send you to prison?
No. Admonition is one option under Section 57, so a first or minor breach may not lead to imprisonment; but a serious or repeated breach, such as a new similar offense, often does.
