— Alan Dorenbos sought to vacate a restitution order, alleging that the order was untimely because it was entered more than 60 days after sentencing. But Dorenbos’ motion was also untimely as it was filed over seven years after the restitution order was entered, far beyond the one-year time limit for collateral attack. We thus affirm the superior court’s ruling denying Dorenbos’ motion.

Facts

Alan Dorenbos was found guilty of second degree murder for killing his wife and was sentenced for that crime on December 8, 1992. On December 3, 1993, the trial court entered an order imposing $9,364.56 in restitution. On July 23, 2001, Dorenbos filed a motion to vacate the restitution order, citing CrR 7.8(b)(4) and (5). The superior court denied the motion on October 16, 2001, ruling that it was untimely.

Analysis

Dorenbos challenges the restitution order, contending that the trial court lacked jurisdiction and statutory authority to enter it because it was untimely under former RCW 9.94A.142(1) (1995), which required that the amount of restitution be determined within 60 days of sentencing.1

*497 But motions brought under CrR 7.8 are expressly subject to the limitation period in RCW 10.73.0902 RCW 10.73.090(1) bars collateral attack brought more than one year after the judgment and sentence becomes final. Dorenbos filed his motion to vacate over seven years after his restitution order became final. He argues, however, that RCW 10.73.090(1) does not apply because the trial court lacked jurisdiction to set restitution beyond 60 days and, therefore, the exception of RCW 10.73.100(5) applied.3 This argument is without merit. Our Supreme Court has held that “untimely imposition of restitution as a condition of a sentence is not a jurisdictional defect.”4 A restitution order entered beyond 60 days is merely voidable, not void for lack of jurisdiction. The exception of RCW 10.73.100(5) thus did not apply.

Dorenbos also contends that RCW 10.73.090(1) applies only to collateral attacks on judgment and sentences. He argues that because he is attacking only a restitution order entered after the trial court entered his judgment and sentence, the statutory time bar does not apply. Contrary to this argument, a restitution order becomes part of the offender’s sentence once imposed.5 Since Dorenbos’ CrR 7.8 motion essentially attacks a portion of his sentence, the time bar of RCW 10.73.090(1) applies.

Dorenbos also argues that the one-year time limit did not apply because an untimely restitution order is facially invalid. RCW 10.73.090(1) forbids collateral attack beyond a year if the judgment and sentence being challenged is “valid on its face.” “[I]nvalid on its face” for *498purposes of RCW 10.73.090(1) means that the judgment’s infirmities are evident without further elaboration.6 The face of Dorenbos’ judgment and restitution order indicate that restitution was set more than 60 days after sentencing. A defendant, however, may waive the time limit of former RCW 9.94A. 142(1) or agree to continue a restitution hearing beyond the deadline.7 To determine whether the order in this case was truly untimely or whether it had been entered late by Dorenbos’ agreement would require us to look beyond the face of the restitution order and judgment. Because of this, we cannot determine “without further elaboration” that the restitution order is facially invalid.8 Dorenbos fails to show that RCW 10.73.090 does not apply and his challenge to his seven-year-old restitution order is time barred.9

Finally, we also note that Dorenbos is not entitled to relief on the merits of his motion.10 Rather than directly appealing his restitution order, Dorenbos opted to collaterally attack it under CrR 7.8(b)(4) and (5).11 A final yet untimely restitution order is not a “fundamental defect” that entitles a defendant to relief on collateral attack.12 In light of this, it cannot reasonably be characterized as an “extraordinary circumstance” warranting collateral relief under CrR 7.8(b)(5). And as mentioned above, an untimely *499restitution order is merely erroneous — it is not “void.”13 Mistakes of law may not be corrected by a motion for relief from judgment under CrR 7.8(b) but must be challenged on direct appeal.14 Thus, the trial court would have erred in vacating Dorenbos’ restitution order under CrR 7.8(b).

We affirm the trial court because Dorenbos’ motion was untimely and also because Dorenbos was not entitled to relief under CrR 7.8(b).
