It's for my granddaughter who is a juvenile and my grandson who was a juvenile. My grandson got a one-year commitment. My granddaughter got into your commitment. And I'm not sure if they got charged at the youthful offenders cuz no one is letting me know anything about it and to see what I can do if they are can get credit.
Attorney Answer
Almost certainly not, if what your grandchildren received were one-year juvenile commitments. New Mexico courts have held that credit for time already spent in detention belongs to a youth actually sentenced as an adult — not to a child given a juvenile disposition.
The general credit statute, NMSA 1978, § 31-20-12, entitles a person who is sentenced as an adult to credit against the sentence for time already spent in presentence confinement. The limiting words there are doing real work.
The two juvenile tracks are different and the labels are not interchangeable. A "serious youthful offender" is defined by § 31-18-15.2(A) as a person fifteen to eighteen charged with and indicted or bound over for first degree murder; for that category, § 31-18-15.3(B) provides that time spent in a juvenile detention facility before trial shall count toward completion of any sentence imposed. A "youthful offender" is the separate category governed by § 32A-2-20, where the court has discretion either to impose an adult sentence — after findings that the child is not amenable to treatment under § 32A-2-20(B)–(C) — or to impose juvenile sanctions under § 32A-2-19. A one-year commitment of the kind you describe is a juvenile disposition under § 32A-2-19(B)(1)(a), not an adult sentence.
State v. Nanco, 2012-NMCA-109, 288 P.3d 527, decided this directly and decided it against the child. A youth charged with first degree murder at fifteen was found to have committed the lesser delinquent acts of voluntary manslaughter and tampering with evidence, and received a juvenile disposition. The Court of Appeals held the credit provisions of §§ 31-18-15.3 and 31-20-12 apply only to a serious youthful offender who is sentenced as an adult, and denied him credit for the twenty-five months he had already spent in juvenile detention. Because the credit statutes speak of a "sentence," the court held the Legislature did not intend that credit to reach juvenile dispositions.
What you can do
1. Find out which track each grandchild was actually on: an adult sentence, or a juvenile disposition. That single fact decides the credit question. 2. Get a copy of each disposition order. Ask the parent or legal guardian to request it, or ask the child's defense attorney directly. 3. If either child was in fact sentenced as an adult, have the attorney raise credit with the sentencing court — that is where the credit claim belongs. 4. If it is a one-year juvenile commitment, shift focus from credit to what is actually available: review of the disposition, release planning, and treatment placement, all through counsel. 5. For information, go through the parent or guardian or the child's attorney. Juvenile cases are closed proceedings, and that is why nobody has been telling you anything — it is not personal. 6. Ask the children's court clerk in the district where each case was filed what a family member may obtain and what the parent or guardian must request.

Holds that the presentence-confinement credit provided by NMSA 1978, §§ 31-18-15.3 and 31-20-12 applies ONLY to a serious youthful offender who is sentenced as an adult, and does NOT apply to a child adjudicated a delinquent offender and given a juvenile disposition. The child there — charged with first degree murder at fifteen but found to have committed the lesser delinquent acts of voluntary manslaughter and tampering with evidence — was DENIED credit for the twenty-five months he had spent in juvenile detention. The court reasoned that because the credit statute speaks of a 'sentence,' and § 31-18-15.3 grants credit specifically to serious youthful offenders who receive a sentence, the Legislature did not intend § 31-20-12 credit to reach juvenile dispositions.

Frequently Asked Questions
Why won't anyone tell me what happened in my grandchildren's cases?
Juvenile proceedings are closed, so the people entitled to information are generally the child's parent or legal guardian and the child's attorney. Ask the parent or guardian to request the disposition order, or ask the defense attorney directly with the parent's permission.
Is there any situation where a juvenile does get credit?
Yes. Section 31-18-15.3(B) provides that a serious youthful offender's pretrial time in a juvenile detention facility counts toward any sentence imposed, and § 31-20-12 gives credit to a person sentenced as an adult. The path to credit runs through being sentenced as an adult, which is not what a one-year juvenile commitment is.
Can the one-year commitment be shortened?
That is a different question from credit and a better one to ask. Section 32A-2-19 governs juvenile sanctions and the court retains authority over the disposition, so the child's attorney is the right person to ask about review, modification, or early release planning.
