If you’ve been arrested for grand theft auto in Murrieta, Temecula, or anywhere in Southwest Riverside County, your case will be filed at the Southwest Justice Center and prosecuted by the Riverside County District Attorney’s office — and the first thing worth understanding is that “grand theft auto” is not a single charge in California. It is two related but distinct offenses, and which one you’re facing changes everything about the case. A Murrieta grand theft auto attorney should be able to tell you early which statute applies, whether the charge can be kept a misdemeanor, and where the prosecution’s case is weakest.
Our office has defended vehicle theft and other theft charges at the Southwest Justice Center for more than 25 years, for clients across Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, and French Valley. These cases turn on details that aren’t obvious from the police report — which statute is charged, what the evidence shows about intent, and what the vehicle was actually worth — and those details are where the defense lives.
Two Different Charges People Call “Grand Theft Auto”
In everyday speech, taking a car gets called “grand theft auto.” In California law, the conduct is covered by two separate statutes with a crucial difference between them:
- Vehicle Code § 10851 — unlawful taking or driving of a vehicle. Often called “joyriding,” this statute covers taking or driving someone else’s vehicle without consent, with intent to deprive the owner of it either permanently or temporarily. The key word is temporarily — you can violate § 10851 even if you always meant to bring the car back. It also reaches someone who drives a vehicle knowing it was already taken.
- Penal Code § 487(d)(1) — grand theft of an automobile. This is the actual “grand theft auto” charge. It requires intent to permanently deprive the owner — meaning to keep the car for good, not just borrow it.
The difference comes down to how long you intended to keep the vehicle. The legacy version of this distinction is widely garbled — including in older material that quotes the § 10851 “permanently or temporarily” language and then describes the crime as requiring permanent intent. Those are two different things, and the gap between them is often the gap between a felony grand theft charge and a far less serious joyriding charge. The first thing we determine in a vehicle case is which statute the Riverside County prosecutor has actually charged, because the entire defense flows from that.
Is Grand Theft Auto a Felony or a Misdemeanor?
Both VC § 10851 and PC § 487(d)(1) are wobblers — a charge the prosecutor can file as either a misdemeanor or a felony. This matters, because a great deal of online information flatly states that auto theft is “usually a felony.” It isn’t automatic; the prosecutor’s choice depends on the vehicle’s value, the circumstances, and the defendant’s record. As a general guide:
- Misdemeanor: up to one year in county jail, plus fines and restitution (court-ordered repayment to the owner).
- Felony: 16 months, 2, or 3 years.
There is one enhancement worth knowing about. Under Penal Code § 666.5, a defendant with a prior felony vehicle-theft conviction who is convicted again faces an elevated felony term of up to four years. For someone with a record, § 666.5 — not the base charge — is often the real driver of exposure, and it’s one of the first things to assess.
Because these are wobblers, the felony-or-misdemeanor decision is discretionary, and at the Southwest Justice Center that discretion sits with the Riverside County prosecutors — which makes it negotiable. A significant part of defending these cases is keeping a charge that could be filed as a felony from being filed or resolved as one.
How Proposition 47 Can Make a Vehicle Case a Misdemeanor
This is the point the older information on this topic almost always misses, and it can be decisive.
Proposition 47, passed in 2014, made theft of property worth $950 or less a misdemeanor (petty theft), regardless of the general grand theft rules. California courts have applied that rule to vehicle cases: when a § 10851 or § 487(d)(1) charge is based on taking a vehicle by theft — that is, taking it with intent to permanently deprive the owner — and the vehicle is worth $950 or less, the charge must generally be treated as misdemeanor petty theft. Plenty of older cars fall under that threshold, so this is frequently the difference between a felony and a misdemeanor.
But there is a critical limit, and it’s the opposite of what most people assume. Proposition 47’s $950 rule applies only to theft-theory cases — taking with intent to permanently deprive. It does not apply to:
- Joyriding — taking with only temporary intent to deprive, and
- Post-theft driving — driving a vehicle you knew was already taken.
Those can be charged as felonies regardless of the vehicle’s value. So the same fact — an inexpensive car — cuts in opposite directions depending on the theory: it can reduce a permanent-intent theft to a misdemeanor, while doing nothing for a joyriding or driving charge. In our experience, the value of the vehicle and the precise theory the prosecution is using are two of the first things worth pinning down, because together they often determine whether a misdemeanor outcome is even on the table.
Where a Vehicle Theft Case Is Heard in Southwest Riverside County
A vehicle theft charge arising in Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley is filed at the Southwest Justice Center, the branch of the Riverside County Superior Court in Murrieta, and prosecuted by the Riverside County District Attorney’s office staff assigned there.
Local knowledge matters in these cases. How the SWJC and the local prosecutors handle value disputes and the joyriding-versus-theft charging decision, how particular judges weigh restitution and probation, and what a realistic resolution looks like there are things learned by working in that courthouse. Attorney Nic Cocis has appeared at the Southwest Justice Center on a near-weekly basis since 1999. There is also a collateral consequence specific to these cases: a VC § 10851 conviction can trigger a DMV review and potential license consequences, which is one more reason to take the charge seriously from the start.
What the Prosecution Has to Prove
To convict under either statute, the prosecution has to establish that you took or drove a vehicle that wasn’t yours, without the owner’s consent, and with the required intent. The intent element is almost always the battleground:
- For grand theft auto (§ 487(d)(1)), the prosecution must prove you meant to keep the vehicle permanently. If the evidence doesn’t show permanent intent, the charge may belong under § 10851 instead — a meaningful reduction.
- For § 10851, the prosecution still has to prove intent to deprive the owner (even temporarily) and lack of consent — and in a driving case, that you knew the vehicle had been taken.
What the prosecution often lacks is direct proof of intent. Many of these cases are built on circumstantial evidence — possession of a recently taken vehicle, a traffic stop, surveillance footage — and that evidence frequently supports more than one explanation. How witness testimony and circumstantial evidence get challenged is often central to the defense.
Defenses to a Grand Theft Auto Charge
The right defense depends on the statute and the facts, but several recur in the vehicle cases we handle:
- Consent. If the owner gave you permission to take or use the vehicle, there is no crime — even if they later claim otherwise. Disputes between family members, partners, and acquaintances over what was authorized are a common source of these charges.
- No intent to permanently deprive. Where the evidence shows you meant to return the vehicle, a grand theft auto charge under § 487(d)(1) may be reduced to the far less serious § 10851 — or defeated entirely if intent can’t be shown at all.
- Proposition 47 value reduction. On a theft theory, a vehicle worth $950 or less should be a misdemeanor. Establishing the vehicle’s actual value can take a felony off the table.
- Mistaken identity. Vehicle cases often rest on who was seen with the car rather than direct proof, and those identifications can be challenged.
- Claim of right. A genuine, good-faith belief that you had a right to the vehicle undercuts the intent the prosecution has to prove.
- Insufficient evidence. Where the proof of intent or knowledge is thin or circumstantial, it may not meet the standard required for a conviction.
When we review a vehicle-theft case, intent is usually where we focus first — because whether the prosecution can prove you meant to keep the car permanently decides both which statute applies and how serious the case really is.
Why a Murrieta Grand Theft Auto Attorney Matters Early
Vehicle theft cases are shaped early. Whether the charge is filed as grand theft auto or as the lesser § 10851 offense, whether it’s a felony or a misdemeanor, whether Proposition 47 applies, and whether a § 666.5 enhancement is in play are all questions that benefit from being addressed before a case hardens. So does the value of the vehicle, which can be the single fact that determines the outcome.
Most importantly, because intent is the heart of these cases, the early account of what happened — and what you say to investigators — can shape everything that follows. These are the questions a Murrieta grand theft auto attorney who knows the Southwest Justice Center should be working through with you in the first conversation, not at trial.
