OPINION
Procedural History
This is appellant’s second appeal of this cause to this court. Originally, in 1991, we affirmed summary judgment on behalf of appellee in cause number 04-91-012-CV based on our finding that appellant failed to controvert the lack of proximate cause which we presumed was established in appellee’s affidavit, from which pages were missing in the record. On rehearing, the missing pages were found. We then reversed the summary judgment on the basis that the appellee’s summary judgment affidavits were legally insufficient because they were conclusory.
On remand, appellee moved for summary judgment on the basis of a new expert witness affidavit. The trial court again granted summary judgment, which appellant appeals on two points of error. Appellee replies with four cross-points.
Factual Background
Appellee Rutherford represented appellant Hall in a medical malpractice claim against the United States under the Federal Tort Claims Act, which was tried unsuccessfully to the bench. Appellant’s daughter Kimberly Hall was bom at Wilford Hall Medical Center and underwent emergency surgery to *424 correct a serious birth defect. Hall contended that Kimberly suffered vocal cord paralysis as a result of the negligence of the physicians or technicians during or immediately after the surgery. After losing in the federal district court, Hall sued Rutherford for legal malpractice, alleging three bases: (1) Rutherford failed to plead and prove a claim for informed consent; (2) Rutherford failed to designate certain fact witnesses and call a Dr. Kosoy to testify; and (3) Rutherford failed to properly investigate important information regarding Hall’s claims.
Analysis
The party moving for summary judgment has the burden of showing that no genuine issue of material fact exists and that it is entitled to judgment as a matter of law.

A legal malpractice action in Texas is based on negligence.
Cosgrove v. Grimes,
1. Affidavits
Affidavits supporting or opposing a motion for summary judgment must be made on personal knowledge and set forth facts which would be admissible in evidence. Tex.R.Civ.P. 166a(f). Statements in an affidavit which are mere conclusions or which represent the affiant’s opinion are insufficient.
See Wise v. Dallas Southwest Media Corp.,
Further, the testimony of a lay witness is not competent to controvert an expert witness’s opinion.

In his first point of error, appellant argues that the trial court erred because questions of fact were raised by the summary judgment proof. Appellee’s summary judgment proof consisted of an affidavit by an attorney, Clem Lyons, who is board certified in medical malpractice litigation. He stated that he gained personal knowledge of the claim and the underlying ease by reviewing the depositions, pleadings, discovery, statement of
*425
facts, opinion, and judgment in the underlying litigation. He stated that his expert opinion was based on this review and his experience in the field of medical malpractice. He stated that he is familiar with the applicable standard of care for practicing attorneys in Bexar County in both the state and federal courts. He specifically addressed each of the alleged negligent actions by appellee and explained why in his opinion the actions were reasonable and within the standard of care. For example, in his analysis of appellee’s alleged failure to plead a theory of informed consent, he stated that based on the facts surroundings the alleged medical errors and the child’s injury, the theory was not a viable one. He also placed this analysis within the context of presenting the case in federal court with a district judge, as opposed to a jury, as the trier of fact, and the prudence of not pleading alternate theories in this context. We conclude that this affidavit was sufficient to negate, as a matter of law, the malpractice claim, because it established that appellee met the standard of care of a reasonably prudent attorney and negated the essential element of causation.
See Anderson,
To oppose this summary judgment proof, appellant presented controverting affidavits of himself and of his expert, attorney Walter Mizell, which he contends are sufficient to raise a fact issue. We first note that the affidavits of Hall and Mizell included in this record are purported to be “true and correct” copies of the affidavits filed in response to appellee’s summary judgment motion in cause number 04-91-012-CV. The copies are not sworn to, lacking both signature and jurat. Instead, they are certified to be true and correct copies by a sworn affidavit executed by appellant’s attorney.
Rule 166a requires affidavits to conform to the provisions of section 312.011(1) of the Government Code and to be based on personal knowledge.
De Los Santos v. Southwest Texas Methodist Hosp.,
2. Deposition
Appellant’s remaining controverting evidence is the deposition of attorney Mizell, who is the appellant’s cousin, and a letter from Dr. Kosoy. Mizell’s deposition testimony was based on factual assertions contained in appellant’s affidavit and as told to him by appellant. An expert may rely on inadmissible facts or data in forming an opinion if they are of the type reasonably relied on by other experts to make opinions or draw inferences. Tex.R.Civ.Evid. 703;
Baylor Medical Plaza Seros. Corp. v. Kidd,
Moreover, Mizell’s testimony fails to raise facts issues regarding the specific instances of malpractice alleged. For example, regarding the alleged failure to pursue a theory of informed consent, he stated, “I am not saying that I have an opinion as to whether informed consent would have been a great theory or not. I based my statement upon [appellant’s] statement that it was a theory that you wanted to present to the judge but because it had not been properly pleaded, he wouldn’t let you present.” At other points he stated to appellee, “[I]f your version of the case is that informed consent was not a viable theory ... I’m not here to argue that”; and “So [informed consent] may have been a viable theory. That’s as far as I can take it....”
Regarding the alleged failure to call more fact witnesses, Mizell conceded that “there’s a judgment call there about how far you go before you get a diminishing return.” Regarding appellee’s failure to call Dr. Kosoy as an expert witness, Mizell stated that he did not know whether Dr. Kosoy, an ear, nose, and throat specialist, was the type of expert appellee should have used instead of an anesthesiologist. In summary, we find that the Mizell deposition failed to give the legal basis or reasoning for his opinions and failed to raise a fact issue that would preclude summary judgment.
Finally, the Mizell deposition wholly failed to show that the medical malpractice suit would have been successful but for the alleged negligence of appellee and failed to address damages, thereby failing to raise genuine issues of material fact concerning two elements of appellant’s cause of action, causation and damages.

3. Unauthenticated Document
Appellant also attached a copy of a letter from Dr. Kosoy as controverting summary judgment evidence. The letter is unauthenticated, unsworn, and unsupported by affidavit, and is therefore not entitled to consideration as summary judgment evidence.
Diaz v. Southwest Wheel, Inc.,
*427 Continuance
In his second point of error, appellant contends the trial court erred in not granting him additional time to take the deposition of Dr. Kosoy. Appellee’s summary judgment motion was set to be heard on May 12, 1994. Appellant had set Dr. Kosoy’s deposition for May 13, 1994. He asked the court for a continuance, which was denied.
Granting a motion for continuance is within the trial court’s sound discretion.
Villegas v. Carter,
Because we affirm the summary judgment, we do not address appellee’s cross points. The decision of the trial court is affirmed.
Notes
. The instant case provides an excellent illustration of the need for the rule outlined above. The purported affidavits offered in opposition to ap-pellee’s summary judgment motion in the record before us differ in several instances from the affidavits filed in cause number 04-91-012-CV, of which they are supposed to be true copies.
