This is a criminal case in which defendant was convicted, after a trial to the court, of perjury. ORS 162.065 (set out infra). He appealed his conviction asserting, inter alia, that there was insufficient evidence that his admittedly false statement was a “sworn” statement to permit him to be convicted of that charge. The Court of Appeals affirmed the conviction. State v. Carr, 125 Or App 270, 863 P2d 1316 (1993). Defendant sought review in this court, again asserting that the evidence against him was insufficient to support a conviction.1 We allowed review and now affirm the decision of the Court of Appeals.
The following facts are undisputed. On the morning of April 26, 1991, defendant appeared before Hansen, a notary public, at her regular place of business and, while in her presence, executed a materialman’s lien claim form that was intended to burden the real property of a person named Sparks. In fact, defendant was not entitled to the lien. Defendant executed the form by providing proof to Hansen of his identity, signing the original of the lien claim form, and signing Hansen’s notary journal. Hansen then stamped the document with her notarial seal and signed it herself. In accordance with her uniform practice in such matters, Hansen did not administer an oral oath or affirmation to defendant before he signed the lien document.
On the same morning, defendant delivered the notarized lien claim form to the Clatsop County Courthouse and submitted it for recording. It was recorded. Defendant later personally served a copy of the lien claim form on Sparks. The hen claim form that defendant served on Sparks contained the following jurat:
“I, Brian L. Carr, being first duly sworn, depose and say: that I am the contractor claimant named in the foregoing instrument; that I have knowledge of the facts therein set *411forth; that all statements made in said instrument are true and correct as I verily believe.
/s/ Brian L. Carr”
(Underlined matters were filled in on otherwise pre-printed form.) The document also contained, adjacent to the jurat, Hansen’s notary stamp and signature.
As noted, the asserted basis for the lien was false. Defendant was indicted for, and convicted by the circuit court of, perjury. Perjury is defined in ORS 162.065(1):
“A person commits the crime of perjury if the person makes a false sworn statement in regard to a material issue, knowing it to be false.”
Defendant acknowledges in this case that the evidence adequately established that he executed, recorded, and served the lien claim, that statements made on the claim were false, that he knew of their falsity, and that the statements were material. Defendant’s sole argument in support of his motion for acquittal is that he did not make a false “sworn” statement, because the notary public before whom he executed the lien claim document did not orally administer an oath or affirmation to him when he executed that document.
ORS 162.055(4) defines the term “sworn statement” to mean
“any statement knowingly given under any form of oath or affirmation attesting to the truth of what is stated.”
(Emphasis supplied.) The jurat in this case recited that “I have knowledge of the facts therein set forth; [and] that all statements made in said instrument are true and correct as I verily believe.” Without question, therefore, defendant was attesting to the truth of the statements in the lien claim. The dispositive issue in this case thus is reduced even further to the narrow question: What does the phrase, “any form of oath or affirmation,” in ORS 162.055(4) mean?
The question is one of legislative intent. In interpreting a statute, our task is to discern what the legislature intended. That inquiry begins with the text of the statutory provision itself, because the text is the best evidence of the legislature’s intent. Also pertinent at that first level of analysis is the context of the statute under consideration. Context *412includes other related statutes. If the legislature’s intent is clear from that inquiry into text and context, no further inquiry is necessary. PGE v. Bureau of Labor and Industries, 317 Or 606, 610-11, 859 P2d 1143 (1993).
The question presented here, viz, what the legislature intended by the phrase, “any form of oath or affirmation,” is not answered by the statutory text alone. The text could mean what defendant argues that it means, although the inclusion of the words “any form of’ before “oath or affirmation” strongly suggests that the legislature was concerned with the substance of the act, rather than the degree of formality by which it was accomplished. We believe, however, that what the text itself leaves uncertain may be resolved by consultation with context.
Another clue to the legislature’s intent with respect to the degree of formality required for a violation of the perjury statute is provided by ORS 162.095(2), which provides: “It is no defense to a prosecution for perjury or false swearing that: * * * The oath or affirmation was taken or administered in an irregular manner * * The message of ORS 162.095(2) is that the legislature was concerned with the substance of the act of swearing, rather than with the formality with which the act was accomplished. This contextual provision strongly suggests, if it does not definitively establish, that the legislature did not intend to require an oral oath or affirmation.
Ranging somewhat farther afield in our examination of context, we find still more support for the proposition that the perjury statute requires no particular form of oral oath or affirmation when we consult the statutes that govern construction hens, ORS 87.001 et seq, and those governing notaries public, ORS ch 194. The construction lien statutes require that the claim of a hen be “verified by the oath of the person,” subject to criminal penalties. ORS 87.035(4). The notarial statutes provide for the taking of a “verification on oath or affirmation,” ORS 194.505(3), but define “oath” or “affirmation” to mean only “a notarial act * * * in which a notary certifies that a person made a vow in the presence of the notary on penalty of perjury.” ORS 194.505(6). (Emphasis supplied.) Finally, ORS 194.515(2) prescribes the *413manner in which a notary is to take a verification on oath or affirmation. It provides:
“In taking a verification upon oath or affirmation, the notarial officer must determine, either from personal knowledge or from satisfactory evidence, that the person appearing before the officer and making the verification is the person whose true signature is on the statement verified.”
The statute makes no mention of any requirement that the vow of the person (ORS 194.505(6)) be taken orally or with any particular form of ceremony.
When the text of the perjury statute is considered together with the range of contextual provisions that we have reviewed, we believe that the legislative intent becomes clear: It is not necessary, in order to be in violation of ORS 162.065(1), that the “sworn statement” of the person charged be one that was made after the formal, oral administration of an oath or affirmation. It is enough that the statement was a vow of the person making the statement and that the vow was made in the presence of the notary; that is, it was made with sufficient formality to impress on the person the seriousness of his or her act.
Defendant’s statement was sufficient to meet the foregoing test: The statement was of a kind that is required by law to be made under oath; defendant intended the hen created by the statement to appear to be legally effective in order to further his fraudulent scheme; he went before a notary in order to obtain what would appear to be a legally effective document; and he signed a statement before that notary that he had been “duly sworn” and that the statements that he made were “true and correct as I verily believe.” The trial judge was entitled to find defendant guilty of perjury based on those facts, and the Court of Appeals properly affirmed defendant’s conviction.
The decision of the Court of Appeals and the judgment of the circuit court are affirmed.
Defendant asserts a second claim of error, but that claim was not preserved at trial. The Court of Appeals declined to address it, as do we. See State v. Carr, 125 Or App 270, 271, 863 P2d 1316 (1993) (describing issue and explaining decision not to address it).
