What to do after a false-name citation or arrest

Write down the encounter while it is fresh. Record why the officer approached, what the officer said, each question asked, the exact answer, whether identification was requested or shown, who else heard the exchange, when the person’s true identity became known, and whether an interpreter was present.

Preserve body-camera, squad-camera, dispatch, 911, booking, jail-call, citation, and computer-aided-dispatch records. Government systems often overwrite recordings under retention schedules. Counsel can send a preservation request before important evidence disappears.

Keep the identification document in its existing condition. Do not alter, discard, replace, or destroy it. A worn, expired, corrected, foreign, temporary, or duplicate card may look unusual without being false or fraudulently altered.

Collect ordinary identity records: birth certificate, passport, immigration documents, driver’s license history, tribal identification, marriage or divorce documents, legal-name-change order, school and employment records, and proof that a claimed nickname is regularly used. The right documents depend on the disputed detail.

Do not contact the person whose identity was allegedly used to coordinate an account. Preserve lawful communications that already exist. A lawyer can investigate without generating an accusation that witnesses were influenced.

A person should not lie in a later interview to fix an earlier statement. It is lawful to ask for counsel and decline a voluntary custodial interview. The defense should first learn which subdivision is charged and what evidence allegedly proves intent to obstruct justice.

Section 609.506 creates three related offenses

Subdivision 1 applies to a peace officer’s qualifying inquiry. It covers three alternatives: a fictitious name other than a nickname, a false birth date, or a false or fraudulently altered identification card. With the required intent, any one can support the misdemeanor.

Subdivision 2 is more serious. It applies when a person gives a peace officer the name and date of birth of another person, again with intent to obstruct justice during a qualifying official inquiry. The statute classifies that conduct as a gross misdemeanor.

Subdivision 3 applies in a criminal proceeding when identifying information is given to a court official. A fictitious name other than a nickname or false birth date is a misdemeanor. Giving another person’s name and birth date is a gross misdemeanor. Court officials include judges, referees, court administrators, and court employees.

The statute’s title mentions a false name, but the actual text is broader and more precise. Prosecutors must charge and prove the correct act and setting. A case about an altered ID should not be tried as if the person spoke another individual’s full identity.

All three subdivisions require intent to obstruct justice. That phrase separates criminal identity deception from a mistake, informal nickname, clerical variation, misunderstanding, memory problem, or answer irrelevant to the officer’s work.

What prosecutors must prove beyond a reasonable doubt

For the ordinary misdemeanor, the State generally must prove: the defendant gave a fictitious name other than a nickname, a false birth date, or a false or fraudulently altered identification card; the recipient was a statutory peace officer; the officer was making inquiries incident to a lawful investigatory stop, lawful arrest, or execution of another duty imposed by law; the defendant intended to obstruct justice; and the act occurred at the charged time and place.

For subdivision 2, the State must prove that the identifying information was the name and birth date of another person. The text uses “and.” A prosecutor should not convert a fictitious name with a random date into the another-person gross misdemeanor without proof that the combined information identified a real other person.

For subdivision 3, the State must prove a criminal proceeding, a court official, the specified false information, and obstructive intent. A conversation with a courthouse visitor or private lawyer is not necessarily communication to a statutory court official.

Identity and attribution remain elements. Body-camera audio may be unclear, several people may be present, or an officer may copy a name from a third party. The prosecution must prove the defendant supplied the disputed information.

Venue and timing must be proved as in other criminal cases. When information is entered remotely, conveyed through an interpreter, or repeated from an earlier document, the State should identify where and when the charged giving occurred.

What counts as a fictitious name

A fictitious name is a made-up identity rather than the person’s true name or a genuine nickname. Invented first and last names are the clearest examples. A false spelling designed to prevent a records match may also be evidence of the offense when paired with obstructive intent.

Not every variation is fictitious. People use shortened forms, middle names, prior surnames, transliterations, cultural naming conventions, married names, professional names, and names appearing differently across records. The defense should determine how the person normally identifies and what the question reasonably called for.

A person may have changed names without every database being current. A legal-name-change order, marriage certificate, immigration record, or updated license can explain why the officer’s return did not match the spoken answer.

Spelling and hearing problems matter. Road noise, stress, accents, hearing impairment, a poor microphone, and phonetic spelling can make an accurate name appear false in an officer’s report. Native audio should be reviewed rather than relying only on a narrative.

The statute does not punish silence as giving a fictitious name. Whether a person must identify in a particular encounter is a separate constitutional and statutory issue. Section 609.506 addresses specified false information given with obstructive intent.

The statute expressly excludes a nickname

Subdivision 1 says “a fictitious name other than a nickname.” Subdivision 3 uses the same exclusion. A real nickname cannot be treated as fictitious merely because it is not printed on a driver’s license.

Whether a term is a nickname depends on facts. Longstanding use by family, work, school, social accounts, email addresses, records, or witnesses may show that the name genuinely identifies the accused. A spontaneous invented alias used once to hide identity looks different.

The nickname exception does not necessarily excuse a false birth date or altered card supplied at the same time. Each statutory alternative must be considered separately.

Nor does a nickname permit a person to appropriate someone else’s full identity. If the name and birth date together belong to another actual person, subdivision 2 can apply even if part of the name resembles a nickname.

Instructions should preserve the statutory exception. A jury asked whether a name was fictitious should be told that a nickname is excluded, with factual disputes left for its determination.

A false date of birth can support the charge by itself

The misdemeanor text uses alternatives. A person can give a correct name yet face a charge for intentionally giving a false birth date to obstruct justice. The State need not prove a fictitious name as well.

Dates are easy to mishear or transpose. Month-day conventions, interpreter errors, poor memory, age-related confusion, intoxication, cognitive impairment, and a one-digit mistake can create an incorrect record without criminal intent.

A corrected answer matters. Immediate clarification—“I said the 14th, not the 40th,” for example—can support mistake. A correction only after the officer discovers a warrant may support the State’s inference, though it does not make guilt automatic.

The State should prove what was actually said. An officer may infer a birth date from a database result, copy one from an old citation, or receive it from a passenger. The statute requires that the defendant give the false information.

For the gross misdemeanor, the name and date must be those of another person. A random date attached to a made-up name ordinarily fits the misdemeanor analysis, not subdivision 2, unless the evidence establishes an actual other identity.

False and fraudulently altered identification cards

Subdivision 1 covers a false identification card and a fraudulently altered identification card. A wholly counterfeit license, another person’s card presented as one’s own, or a genuine card with a substituted photograph or changed birth date are common allegations.

The document’s condition should be examined. Laminate separation, fading, damage, state-issued corrections, punched expiration marks, temporary paper credentials, or protective coverings are not necessarily fraudulent alteration.

Possession alone is not the charged act under this provision. The State must prove the card was given to the officer during a qualifying inquiry and with intent to obstruct justice. A card found in a wallet may implicate other law, but it does not automatically establish section 609.506.

Forensic examination can address printing, substrate, barcode data, photograph substitution, security features, and physical edits. Chain of custody matters when the document’s condition is disputed.

A person may mistakenly hand over an old, duplicate, or family member’s card. Location in the wallet, resemblance, immediate reaction, other documents supplied, and explanation may distinguish accident from intentional obstruction.

Using another real person’s name and birth date

Subdivision 2 protects both the justice system and the person whose identity is used. A false record can attach a citation, arrest, warrant, or investigation to someone who was not present. For that reason, Minnesota treats this alternative as a gross misdemeanor.

The statute requires the name and birth date of another person. Prosecutors commonly rely on database matches, testimony from the other person, prior access to that person’s information, or a later admission to prove the identity was real.

Shared names require care. Relatives may have similar or identical names. A suffix, middle name, birth date, address, physical description, and license record can show whether the defendant actually supplied another person’s identity or the officer matched incomplete information incorrectly.

Intent remains essential. Even a combination belonging to another person does not create strict liability. The State must prove the defendant intended to obstruct justice, not merely that a database happened to locate a match.

Correction and harm to the other person matter factually. Promptly clarifying identity before a citation or warrant issues can support mitigation or lack of intent. A delayed discovery after the other person is arrested can make resolution harder but does not eliminate the State’s burden.

Intent to obstruct justice is not optional

The statute does not criminalize every false identifying statement. It requires a purpose to interfere with the administration or enforcement of law. Avoiding discovery of a warrant, preventing a records check, evading a citation, concealing one’s role, or shifting blame to another can support that inference.

Intent is usually proved circumstantially. Repeating the false information, selecting a relative with a clean record, possessing memorized details or another person’s card, changing the account after a warrant appears, or admitting the reason can be significant.

But the inference is not automatic. Fear, confusion, language barriers, mental-health symptoms, intoxication, poor memory, uncertainty about an official name, or concern unrelated to justice can explain an incorrect response. Voluntary intoxication has limited use under Minnesota law and must be analyzed carefully, but the surrounding condition may still affect whether the State proves intent.

In an official but noncriminal task, the connection to justice may be weaker. The State should identify what investigation, arrest, process, or duty the person intended to obstruct.

A later true statement does not erase a completed offense, but timing can reveal the original intent. Immediate correction before any records check differs from disclosure only after fingerprints establish identity.

The officer’s question must arise from a qualifying duty

Section 609.506 does not apply to every conversation with a police employee. The officer must make the inquiry incident to a lawful investigatory stop, lawful arrest, or execution of another duty imposed by law.

Traffic stops, Terry stops based on reasonable suspicion, arrests supported by probable cause, service of legal process, welfare checks, crash investigations, and execution of warrants may present qualifying circumstances, depending on the facts and legal authority.

Casual conversation, personal curiosity, an off-duty dispute, or a request untethered to an official legal duty may not meet the text. The defense should identify the law imposing the claimed duty and the relationship between that duty and the identity question.

The inquiry need not use formal words. “What is your name?” or a request for identification can suffice if made in the qualifying setting. But an officer’s assumption based on a third party’s answer is not information given by the accused.

Timing matters. An encounter can begin consensually, become a detention, and later become an arrest. The defense should determine when the disputed answer occurred and what authority existed at that moment.

The statute expressly requires a lawful stop or arrest when that is the basis

If the State relies on an investigatory stop, the officer generally needs specific, articulable facts supporting reasonable suspicion of criminal activity. A hunch is not enough. The defense should review all facts known to the officer before the seizure.

If the State relies on arrest, probable cause and lawful authority matter. A defect in the stop or arrest can defeat the statutory circumstance and may also support suppression of resulting evidence.

Not every police contact is a seizure. A person may voluntarily speak with an officer. Section 609.506 can still apply when the inquiry is incident to another legally imposed duty, but the State must identify that duty rather than treating all officer questions as covered.

Body-camera video, dispatch information, witness reports, location, timing, officer testimony, and the point at which a reasonable person would feel unable to leave are important. A later-discovered warrant cannot retroactively create reasonable suspicion for an earlier stop.

Suppression and sufficiency are distinct. Suppression asks whether evidence resulted from unconstitutional police action; sufficiency asks whether statutory elements were proved. The same lawfulness problem can affect both, but remedies require careful briefing.

The recipient must be a statutory peace officer

Subdivision 1 incorporates Minnesota’s peace-officer definition in Minn. Stat. § 626.84, subd. 1(c) (2026). Licensed or otherwise statutorily recognized law-enforcement officers generally qualify.

Not every government employee, security guard, probation employee, corrections worker, dispatcher, or civilian police employee is necessarily a peace officer under that definition. Job title, licensure, employing agency, and assigned authority should be verified.

An off-duty officer may still be exercising a legal duty in some circumstances, but employment status alone does not answer whether the inquiry occurred while performing the kind of official act the statute requires.

When information passes through an interpreter, civilian clerk, or another officer, the State should establish to whom it was given and under what authority. Accomplice or agency arguments cannot erase statutory recipient language.

Subdivision 3 uses a different recipient: a court official in a criminal proceeding. A prosecutor should not blend the peace-officer and court-official alternatives.

False identity in a criminal court proceeding

The court-official provision applies “in any criminal proceeding.” That can include identifying oneself at an appearance, booking-related court intake, filing, payment, warrant process, or other step in a criminal case, depending on the circumstances.

The statute expressly defines court official to include a judge, referee, court administrator, or any court employee. Private defense counsel, prosecutors, spectators, and courthouse security personnel are not listed merely because they are in the building, though another role or statute may apply.

A made-up name other than a nickname or false birth date given with obstructive intent is a misdemeanor. Another real person’s name and birth date given with that intent is a gross misdemeanor.

Written information can qualify as giving. Forms, e-filed documents, payment records, and remote-hearing statements may be evidence. Authentication and authorship are critical when staff entered the data or an account was shared.

A clerical mistake by a court employee is not a defendant’s false statement. The defense should compare the original form, audio, register of actions, correction history, and any identification presented.

Evidence that commonly determines the case

Body-camera audio and video are often central. They can establish the officer’s question, the answer, context, warnings, confusion, correction, tone, language ability, and the stage of the encounter. A report is a summary, not a substitute for the recording.

Dispatch and database logs show what officers searched, what combinations they tried, when a warrant or record appeared, and whether a supposed false answer may instead be a transcription or matching error.

Identification documents should be photographed and preserved. Barcode scans, licensing history, state records, immigration documents, name-change orders, and issuing-agency testimony may confirm authenticity or explain discrepancies.

Intent evidence includes outstanding warrants, license status, probation conditions, prior knowledge of another person’s data, statements, repeated answers, and timing of correction. Such evidence may also be unfairly prejudicial or subject to limiting rules; admissibility must be addressed before trial.

Language and disability evidence can be essential. Interpreter recordings, proficiency records, hearing aids, cognitive evaluations, medication, and contemporaneous observations may explain why an answer was misunderstood or inaccurate. The defense need not prove a diagnosis to point out reasonable doubt.

In court-official cases, obtain hearing audio, video, forms in original format, electronic filing logs, clerk notes, account access history, and corrected entries. The source of each field should be documented.

Related charges are not interchangeable

Obstructing legal process under section 609.50 addresses physical obstruction, resistance, and specified interference. The Minnesota Supreme Court has limited its broad language to conduct that substantially obstructs or hinders. A false-name charge has its own precise elements.

Identity theft under section 609.527 generally requires transferring, possessing, or using another’s identity without consent with intent to commit, aid, or abet unlawful activity. Giving another person’s name and birth date can trigger both inquiries, but the offenses are not identical.

Forgery and identification-card statutes may apply to counterfeit or altered documents. Prosecutors must still prove the document and mental-state elements of each charged count.

False reporting under section 609.505 concerns knowingly false information about another person’s conduct supplied to an on-duty officer with intent that the officer rely. A lie about one’s own name does not automatically satisfy that offense.

Driving after revocation, warrant offenses, controlled-substance possession, or the underlying event that caused the stop may be charged separately. A false-name defense should not assume that dismissal of one count resolves all others.

Minnesota’s single-behavioral-incident statute can limit multiple punishment for conduct forming one incident, but charging and conviction questions depend on elements, objectives, time, place, and the final disposition.

Misdemeanor and gross-misdemeanor consequences

The subdivision 1 offense and the first sentence of subdivision 3 are misdemeanors. Under Minn. Stat. § 609.02, subd. 3 (2026), the maximum is 90 days in jail, a $1,000 fine, or both.

Subdivision 2 and the another-person alternative in subdivision 3 are gross misdemeanors. Under Minn. Stat. § 609.0342 (2026) and section 609.02, the maximum is 364 days and a $3,000 fine.

Those are ceilings, not automatic sentences. A court can consider criminal history, underlying purpose, harm to another person, correction, cooperation, acceptance of responsibility, employment, treatment needs, and other lawful factors.

Ordinary probation may extend up to one year for a misdemeanor and two years for a gross misdemeanor under Minn. Stat. § 609.135 (2026), subject to statutory rules and exceptions.

Immigration consequences require individualized advice. A label such as “misdemeanor” does not decide federal immigration treatment, and use of another person’s identity or an offense involving dishonesty may create issues beyond the jail maximum.

A record can affect employment, licensing, housing, and credibility assessments. The availability and timing of expungement depend on the disposition, sentence completion, statutory category, later history, and current law.

What Minnesota appellate decisions teach

In State v. Russell, No. C9-01-2215, 2002 WL 31455205, at *2–3 (Minn. Ct. App. Nov. 5, 2002) (nonprecedential), officers testified that the defendant gave his cousin’s name and birth date and later revealed his identity after police found drug paraphernalia; the true identity disclosed an outstanding felony warrant. The court upheld the subdivision 2 conviction and rejected an as-applied vagueness challenge. It explained that using a false name to avoid arrest or investigation or “to pass blame to another” can show intentional obstruction.

Russell is nonprecedential and fact-specific. It does not mean every database mismatch proves intent. It is useful because it identifies the statute’s limiting setting: an officer’s inquiry during a lawful stop, arrest, or another lawfully imposed duty.

In State v. Perkins, No. CX-97-905, 1997 WL 687681, at *2 (Minn. Ct. App. Nov. 4, 1997) (nonprecedential), the court observed that giving a false name is criminal only when done with “intent to obstruct justice.” The decision primarily concerned a search and did not announce a broad elements test, but its point about intent tracks the statute’s text.

In Morales-Reyes v. State, No. A05-959, 2006 WL 997711, at *2 (Minn. Ct. App. Apr. 18, 2006) (nonprecedential), the defendant sought to withdraw an old plea. The record included presentation of another man’s driver’s license and disclosure of the true identity only after officers found a warrant linked to the card. The court concluded the limited record supported the plea’s intent basis.

These nonprecedential decisions may be persuasive but are not binding in the same way as a precedential opinion. They should be cited honestly and not used to erase factual differences, constitutional questions, or the State’s burden of proof.

How a Minnesota defense lawyer evaluates the charge

No intent to obstruct. The answer may result from mistake, confusion, language, memory, a record discrepancy, or ordinary use of a familiar name.

Nickname. The statute expressly excludes a nickname from its fictitious-name alternative. Regular use can be documented.

Accurate identity. A legal name change, prior surname, transliteration, duplicate record, or database error may explain why the officer thought truthful information was false.

Wrong subdivision. A made-up name with a random date is not necessarily the name and birth date of another real person required for the gross misdemeanor.

Unlawful stop or arrest. When the inquiry rests on a detention or arrest, the express statutory lawfulness requirement and constitutional suppression law must be examined.

No qualifying duty. A casual or personal inquiry may not be incident to a stop, arrest, or duty imposed by law.

Wrong recipient. A security employee or civilian worker may not be a statutory peace officer; a private participant may not be a court official.

Did not give the information. Another person, old record, database, interpreter, clerk, or officer may be the source.

Document not false or altered. Damage, expiration, state-issued correction, or unusual appearance does not establish counterfeit or fraudulent modification.

Reasonable doubt from recording. Body-camera audio can contradict the report, show an immediate correction, or reveal that the question was never asked clearly.

The best defense connects the statutory language to a precise encounter timeline. What legal authority existed, what question was asked, what answer was heard, what records were checked, when any correction occurred, and what objective evidence shows the person’s purpose?
