In Indiana, a notice of intent to seek habitual offender status is a separate charging document the prosecutor files alongside a felony case, alleging that the defendant has the prior felony convictions needed to trigger a sentencing enhancement under Indiana Code 35-50-2-8. If the allegation is proven, the court adds 3 to 20 additional years of prison time to the sentence for the current felony, and none of that added time can be suspended or served on probation.1Indiana General Assembly. Indiana Code 35-50-2-8 – Habitual Offenders
The filing is not a new criminal charge. It is an allegation attached to the current felony case that, if the state proves it, forces the judge to stack extra years onto the underlying sentence.
What the Notice Must Allege
To seek the enhancement, the state must allege that the defendant, after being convicted of the current felony, has at least two prior unrelated felony convictions. “Unrelated” has a specific meaning: the prior offenses had to be committed at separate times, not as part of a single criminal episode, and each later offense had to happen after sentencing for the one before it. The statute also references a separate tier involving three prior unrelated felonies, which may carry different qualification conditions.1Indiana General Assembly. Indiana Code 35-50-2-8 – Habitual Offenders
Not every old conviction counts. For prior felonies at the lower end of the severity scale (Level 5, Level 6, or the older Class C and Class D classifications), there is a ten-year lookback. If more than ten years have passed between the defendant’s release from prison, probation, or parole for at least one of those prior felonies and the date of the current offense, those lower-level convictions cannot be used. Higher-level prior felonies have no such time limit, so a decades-old serious felony can still support the enhancement.1Indiana General Assembly. Indiana Code 35-50-2-8 – Habitual Offenders
One important boundary: the state cannot seek the habitual offender enhancement when the current offense started as a misdemeanor and was upgraded to a felony solely because of a prior conviction. The enhancement applies only where the current felony stands on its own.
How and When the Notice Is Filed
The habitual offender allegation is not folded into the original charging instrument. The state files it on pages separate from the rest of the charges, and it must be brought by information or indictment with the same procedural safeguards that apply to any criminal charge, including the right to an initial hearing. The jury or judge deciding guilt on the underlying felony never sees the allegation during the guilt phase of trial.1Indiana General Assembly. Indiana Code 35-50-2-8 – Habitual Offenders
The allegation is decided in a distinct phase after conviction. If the defendant was convicted by a jury, that same jury reconvenes for a sentencing-phase hearing to determine whether the alleged priors qualify. If the conviction came from a bench trial or a guilty plea, the judge alone decides. The Indiana Supreme Court reinforced in Harris v. State (2023) that the jury in a habitual offender proceeding must be allowed to make the ultimate determination of whether the defendant qualifies, and that the defendant cannot be subjected to additional questioning by either side during this phase.2Indiana Courts. Harris v State
The state’s burden is the same as for the underlying charge: proof beyond a reasonable doubt.
What the Enhancement Adds to a Sentence
If the allegation is proven, the amount of extra prison time depends on the severity of the current felony conviction:1Indiana General Assembly. Indiana Code 35-50-2-8 – Habitual Offenders
- Murder or a Level 1 through Level 4 felony: an additional fixed term of 8 to 20 years.
- Level 5 or Level 6 felony: an additional fixed term of 3 to 6 years.
The enhancement attaches to the felony conviction carrying the highest sentence. It is not a separate crime and not a consecutive sentence in the traditional sense; the extra years are added directly to the sentence for that conviction.
The most consequential feature is that the enhancement is nonsuspendible. A judge cannot convert any part of it to probation or suspended time. Every year must be served. For someone convicted of a Level 3 felony who also receives a 15-year enhancement, those 15 years are locked in on top of whatever the base sentence requires.
Judges do keep meaningful discretion over where within the range the enhancement lands. The 8-to-20-year spread is wide, and factors like the defendant’s age, mental health, substance abuse history, rehabilitation efforts, the circumstances of the current offense, and the nature and age of the priors all shape the number. Nonviolent priors from years ago and evidence of rehabilitation tend to push toward the lower end; a pattern of violent, escalating conduct pushes toward the maximum.
Why the Notice Matters Before Trial
In practice, the notice of intent is one of the most powerful tools prosecutors have in plea negotiations. When a defendant has the qualifying record, prosecutors in many Indiana counties routinely file the enhancement even in cases where they might not pursue it at sentencing. The threat of 8 to 20 additional nonsuspendible years gives the state enormous leverage.
The allegation can be dropped or reduced as part of a negotiated plea. A defendant facing a Level 4 felony with a habitual offender allegation attached might agree to plead guilty to the felony in exchange for the state dismissing the enhancement. Strong pretrial advocacy can sometimes persuade prosecutors to withdraw the filing, especially when the supporting facts are weak or the combined sentence would be grossly out of proportion to the current offense.
This is why the filing shapes case outcomes long before any sentencing hearing. Defendants with viable defenses to the underlying felony may still feel the risk of an extra decade or more is too great to test at trial.
How to Challenge the Notice
Attacking the Prior Convictions
Indiana law generally bars collateral attacks on prior convictions during the habitual offender proceeding, but there is an exception for priors obtained in violation of constitutional rights. If a prior felony resulted from a case where the defendant had no attorney and did not validly waive the right to one, or where a guilty plea was not made knowingly and voluntarily, that conviction may be excluded from the calculation.1Indiana General Assembly. Indiana Code 35-50-2-8 – Habitual Offenders
Knocking out even one qualifying conviction can end the enhancement. If the state needs two unrelated priors and one is excluded, the entire allegation collapses.
Challenging the “Unrelated” Requirement
The priors have to be unrelated and committed at different times. If two prior convictions arose from the same set of events or the same criminal episode, they may count as only one for enhancement purposes. If the timeline does not show that the second offense was committed after sentencing for the first, the sequential requirement is not met. Court records sometimes rely on conviction dates that, examined closely, do not actually satisfy that sequence.
Lookback Arguments
For Level 5, Level 6, and the older Class C and Class D priors, the ten-year lookback is another avenue. If the defendant was released from prison, probation, or parole more than ten years before the current offense, those priors are too old to use. Pinpointing the exact release date can be complicated when someone served time in multiple facilities or had parole revoked and reinstated, and that is often where defense counsel focuses.
The Right to a Jury Determination
Under Apprendi v. New Jersey, any fact that increases a penalty beyond the statutory maximum must be submitted to a jury and proved beyond a reasonable doubt. Indiana’s procedure already reflects this when the underlying case was tried to a jury. The U.S. Supreme Court extended the principle in Erlinger v. United States (2024), holding that the Fifth and Sixth Amendments require a unanimous jury to determine beyond a reasonable doubt whether a defendant’s prior offenses were committed on separate occasions under the federal Armed Career Criminal Act. The Court noted that states should adjust to the implications of that ruling for their own habitual offender laws.3Supreme Court of the United States. Erlinger v United States
What Erlinger means for Indiana cases going forward is still developing. It could strengthen arguments that any factual dispute about whether priors were truly unrelated or committed on separate occasions must go to a jury rather than being resolved by a judge.
Arguing for the Low End of the Range
Even when the enhancement technically applies, the sentencing hearing is the last real opportunity to shape the outcome. Judges cannot suspend the enhancement, but they can set it anywhere within the 8-to-20-year or 3-to-6-year window. Evidence of rehabilitation, completed treatment programs, educational achievements, the defendant’s age and mental health, and the relative severity of the current offense all factor into where the judge lands. The difference between 8 and 20 nonsuspendible years is significant, and it is decided at that hearing.
