174 S.E.2d 627 (1970)
STATE of North Carolina
v.
John Lewis SIMMONS.
No. 7019SC239.
Court of Appeals of North Carolina.
June 24, 1970.
*628 Atty. Gen. Robert Morgan, by Asst. Atty. Gen. Bernard A. Harrell, for the State.
Thomas K. Spence, Concord, for defendant.
BROCK, Judge.
Helen B. Simmons testified that she and defendant were married in York, South Carolina, on 17 May 1952. Thereafter the State was allowed to introduce into evidence the marriage license for the restricted purpose of corroborating the testimony of Helen B. Simmons. Defendant testified that the signature on the marriage license was not his signature and offered into evidence his driver's license, his social security card, and a paper upon which he had written his name five times for the purpose of demonstrating to the jury his genuine signature. Upon objection, these items were excluded from evidence, and defendant assigns this as error. Defendant contends the jury should have been allowed to examine and compare the signatures offered by him with the signature on the exhibit offered by the State. Thus, defendant raised the issue of the genuineness of the signature on the marriage license.
"[I]n North Carolina, where the early view was that the jury could not, under any circumstances, make their own independent examination of handwriting, the courts, while finally relaxing this rule somewhat, still would only allow the jury to examine a disputed writing and an admitted or proved genuine specimen to the extent of having an expert witness, or witness acquainted with the person's handwriting, compare the papers in the presence of the jury and point out the similarity or difference, as the case might be; that is, the jury could only pass upon the genuineness of the disputed writing upon the testimony of witnesses." Annot., 80 A.L.R.2d 272, 279 (1961).
*629 In 1913 G.S. § 8-40 was enacted permitting witnesses to compare a disputed writing with a proved genuine writing and providing that the writings and the evidence of witnesses might be submitted to the court and jury as evidence of the genuineness or otherwise of the disputed writing. This changed the rule existing theretofore, and comparison by the jury has been approved. If the genuineness of a signature or writing is established to the satisfaction of the judge, a witness may compare the established writing with the disputed writing; and then the testimony of the witness and the writings themselves may be submitted to the jury. Newton v. Newton, 182 N.C. 54, 108 S.E. 336; In re Will of Gatling, 234 N.C. 561, 68 S.E.2d 301.
However, neither G.S. § 8-40, nor our rules of evidence, permits the jury, unaided by competent opinion testimony, to compare writings to determine genuineness.
Defendant next contends there was a fatal variance between the State's allegata and its probata in that the indictment charged defendant with bigamy in the marrying of one Mary Katherine Goodman yet the evidence introduced by the State was that defendant was presently married to one Margaret Catherine Simmons; and that this constituted prejudicial error.
There is no merit to this contention. Defendant admitted his marriage to Margaret Catherine Simmons. He did not question or object to her identity at the trial. This assignment of error is overruled.
Defendant further assigns as error several portions of the judge's charge to the jury. We have carefully examined these assignments of error in the light of the evidence and the charge as a whole, and, if it can be said there was some technical error, we find no prejudicial error. In our opinion the case was submitted to the jury in such a manner that there can be no doubt the jury understood the applicable legal principles.
In the entire trial we find no prejudicial error.
No Error.
