RULE 11. SIGNINGS OF PLEADINGS.

Every pleading of a party represented by an attorney shall be signed by at least one attorney of record in his individual name whose address shall be stated.  A party who is not represented by an attorney shall sign the pleading and state his address except when otherwise specifically provided by rule or statute.  Pleadings need not be verified or accompanied by affidavits.  The signature of an attorney constitutes a certificate by him that he has read the pleading; that to the best of his knowledge, information, and belief, there is good ground to support it, and that it is not interposed for delay.  If a pleading is not signed or is signed with intent to defeat the purpose of this section, it may be stricken as sham and false and action may proceed as though the pleading had not been served.
