This is a very serious allegation and is apparently based solely on the fact that (in Texas), the affiants live at a distance from Tyler, Texas.
However, the entire argument is purely based on suspicion.
"If, as suspected, the Affiants did not appear before Mr. Beard, then the Fraudulent
Affidavits to the Response are inadmissible and constitute an attempt to commit fraud upon the
Court. See Allison v. Conglomerate Gas II L.P., 02-13-00205-CV, 2015 WL 5106448, at *9 (Tex.
App.—Fort Worth Aug. 31, 2015, no pet.)."
There's NOTHING in the record besides that supporting this allegation. Not even an allegation that one of the witnesses is known to have been somewhere else at the time. Nothing. Yet, it's somehow completely implausible that with a month's notice, a lawyer could get some witnesses together for a signing, even though this happens every day.
For just how ludicrous this argument is, imagine that I responded to a report of a court hearing by printing out the locations of the residences of everyone claimed to be in court and claimed the hearing never happened because some of them lived hundreds of miles away.
Nevertheless, the defendants call them "Fraudulent Affidavits" and otherwise make gravely serious allegations.
If they have no basis for these claims, their scandalous claims themselves should be stricken.
