912 A.2d 416 (2006)
STATE
v.
Edward VASHEY.
No. 2004-175-C.A.
Supreme Court of Rhode Island.
December 20, 2006.
Aaron L. Weisman, Providence, for Plaintiff.
Catherine A. Gibran, Providence, for Defendant.
Present: WILLIAMS, C.J., GOLDBERG, FLAHERTY, SUTTELL, and ROBINSON, JJ.

OPINION
Chief Justice WILLIAMS, for the Court.
The defendant, Edward Vashey (defendant), appeals a ruling of the Superior Court denying a motion to vacate his Alford plea to second-degree child molestation. The defendant argues that his plea should be set aside because he was not informed that he would be required to register as a sex offender for the duration of his fifteen-year probation as a consequence of his plea. This case came before *417 the Supreme Court for oral argument on December 5, 2006, pursuant to an order directing the parties to appear and show cause why the issues raised in this appeal should not summarily be decided. After hearing the arguments of counsel and examining the record and the memoranda that the parties filed, we are of the opinion that this appeal may be decided at this time, without further briefing or argument. For the reasons hereinafter set forth, we affirm the judgment of the Superior Court.

I

Facts and Travel
Between February 1 and May 31, 1999, defendant allegedly molested his then seven-year-old daughter. On December 8, 2000, defendant was indicted on one count of first-degree child molestation in violation of G.L. 1956 § 11-37-8.1.[1] Thereafter, at a hearing on December 4, 2001, defendant entered a plea in accordance with North Carolina v. Alford, 400 U.S. 25, 91 S.Ct. 160, 27 L.Ed.2d 162 (1970),[2] to the amended charge of second-degree child molestation in violation of § 11-37-8.3.[3] Despite ensuring that defendant acknowledged the constitutional rights he was forgoing by entering the Alford plea, the hearing justice did not explicitly inform defendant that, as a consequence of his plea, he would be required to register as a sex offender pursuant to Rhode Island's Sexual Offender Registration and Community Notification Act, G.L. 1956 chapter 37.1 of title 11. Once the hearing justice was satisfied that defendant made his plea voluntarily, intelligently and knowingly, the justice accepted it.
In addition to a no-contact order, defendant was sentenced to fifteen years imprisonment, the entire term suspended, with fifteen years probation. At the conclusion of the hearing, the following colloquy took place:
"[COURT:] All the statutory requirements, which I understand have been explained to the defendant, will apply. Am I correct?
"[ATTORNEY:] Yes, your Honor, you are."
*418 Shortly after entering his Alford plea, defendant filed a motion titled "Motion to Vacate Plea" on December 13, 2001.[4] Thereafter, defendant's attorney sought to withdraw his representation, which, according to defendant's attorney, was precipitated by correspondence from defendant expressing his dissatisfaction with his counsel. Before these motions could be heard, the judgment of conviction against defendant for second-degree child molestation was entered on January 14, 2002. Two days later, at the hearing on the two outstanding motions, the hearing justice granted defendant's attorney's motion to withdraw and then granted defendant's impromptu request to withdraw his motion to vacate the Alford plea.
With new representation, defendant filed a motion entitled "Defendant's Motion to Withdraw Nolo Contendere Plea" on August 22, 2003. At the hearing on this motion, defendant argued that his plea should be set aside because, before entering the Alford plea, he never was informed (1) that he would be under the supervision of the state's probation program[5] or (2) that he would have to register as a sex offender for the duration of his probationary period. After noting that defendant had signed the plea form indicating that he had discussed the form with his attorney and after recalling that defendant voluntarily and intelligently had entered his Alford plea, the hearing justice denied defendant's motion. The defendant filed a timely appeal.

Analysis
The defendant argues that his Alford plea was involuntary because, before entering the plea, he never was informed that, as a consequence thereof, he would be required to register as a sex offender for the duration of his fifteen-year probation.

A

Standard of Review
A motion to withdraw a plea "is addressed to the sound judicial discretion of the court and * * * a decision of the court thereon will not be disturbed by this [C]ourt unless there is a clear abuse of discretion." State v. Eason, 786 A.2d 365, 367 (R.I.2001).

B

Timeliness of the Motion to Vacate
We must first determine whether this appeal is properly before the Court. Rule 32(d) of the Superior Court Rules of Criminal Procedure provides that "[a] motion to withdraw a plea of guilty or of nolo contendere may be made only before sentence is imposed or deferred or probation is imposed or imposition of sentence is suspended." "Once a defendant has entered a plea of guilty or of nolo contendere and sentence has been imposed, any issue relating to the validity of the plea must be raised by way of postconviction relief." State v. Desir, 766 A.2d 374, 375 (R.I.2001). Furthermore, "[t]he proper avenue by which a defendant must proceed when attacking the voluntariness of a plea or when making a claim of ineffective assistance of counsel is an application for postconviction relief * * *." Id. *419 This requirement is not merely a superfluous technicality: "Unless a defendant complies with the procedure for postconviction relief, [this Court] shall not have the benefit of a full record and a decision of the Superior Court * * *." State v. Farlett, 490 A.2d 52, 54 (R.I.1985).
It is undisputed in this case that defendant was sentenced on December 4, 2001, and that the motion to vacate his Alford plea was not filed, at the earliest, until December 13, 2001, well after defendant had been sentenced.[6] Nevertheless, defendant urges this Court to treat his untimely motion to vacate the Alford plea as an application for postconviction relief pursuant to G.L. 1956 chapter 9.1 of title 10.
Although, admittedly, this Court previously has done exactly as defendant suggests, it was only when a complete record was available for appellate review. See State v. Williams, 122 R.I. 32, 36-37, 404 A.2d 814, 817 (1979) (treating a motion to set aside a guilty plea as an application for postconviction relief in part because "the necessary record [was] before [the Court]"). In the present case, the lack of a fully developed record from a postconviction relief proceeding is fatal. Without it, we are left with no way to ascertain whether defendant's counsel, in fact, made the omission defendant alleges or whether defendant actually did not know that, as a result of entering an Alford plea, he would be required to register as a sex offender for the duration of his probation. Instead, we would be forced to rely exclusively upon defendant's own self-serving averments made at the September 2003 hearing on his motion to withdraw the nolo contendere plea. Accordingly, we hold that defendant's appeal is not properly before this Court.

Conclusion
For the reasons set forth herein, we affirm the judgment of the Superior Court. The record shall be remanded to the Superior Court.
NOTES
[1]  General Laws 1956 § 11-37-8.1 provides:

"A person is guilty of first degree child molestation sexual assault if he or she engages in sexual penetration with a person fourteen (14) years of age or under."
Before this indictment was handed down, on February 8, 2000, a criminal complaint and District Court warrant were filed against defendant for the identical charge. At the time, defendant was on probation for a 1994 sentence he had received for felony assault: twelve years imprisonment, with one year and eight months to serve, ten years and four months suspended with probation. In July 2000, it was determined that defendant had violated his probation. Accordingly, defendant's previously suspended sentence was vacated and he was sentenced to serve ten years and four months; five years and four months of that reinstated sentence were suspended. This Court affirmed that adjudication in State v. Vashey, 823 A.2d 1151 (R.I.2003).
[2]  As we have explained previously,

"`The so-called Alford plea is a procedure approved by the Supreme Court of the United States under which a person charged with a criminal offense may plead guilty even though he maintains his innocence as long as the state presents a factual basis for such plea through evidence other [than] the defendant's own admission.' * * *. However, although a criminal defendant may be relieved of the embarrassment of admitting participation in the crime or comforted by the fact that he or she has maintained his [or her] innocence and the victim sometimes is left in a quandary about what occurred during the plea proceeding, the result is abundantly clear: the defendant stands convicted of the crime." Armenakes v. State, 821 A.2d 239, 242 (R.I.2003).
[3]  Section 11-37-8.3 provides:

"A person is guilty of a second degree child molestation sexual assault if he or she engages in sexual contact with another person fourteen (14) years of age or under."
[4]  It appears that the identical motion to vacate defendant's plea was filed in the Superior Court on December 18, 2001.
[5]  The defendant does not pursue this argument on appeal.
[6]  This is a generous reading of the record. As we explain above, a motion to vacate defendant's Alford plea was filed on December 13, 2001, but was withdrawn upon defendant's own request at a hearing on January 16, 2002. Subsequently, a motion, titled "Defendant's Motion to Withdraw Nolo Contendere Plea," was filed on August 22, 2003, and it was the motion justice's denial of this motion from which defendant takes his appeal.
