OPINION

ROBERTSON, Justice.

This is an appeal from a summary judgment granted in favor of appellee in a suit to collect a note. The issues before us concern Gose’s individual liability on the note and the sufficiency of the service of copies of pleadings. We affirm.

Appellants executed a promissory note to appellee in satisfaction of an outstanding account for drilling services. Appellee filed suit seeking recovery from Gose and Retamco, jointly and severally. Gose and Retamco filed a general denial and asserted no defenses to the execution of the note or the signature thereon. Appellee filed its motion for summary judgment with a copy of the note and an affidavit setting forth the necessary facts and elements for recovery on the note. Appellants filed a motion in opposition but it only contested the suffi *521 ciency of appellee’s summary judgment proof.

In their first point of error, appellants contend there is no support in either the pleadings or summary judgment evidence to support the liability of Gose, individually. We disagree.

Concerning the pleadings, appellee’s original petition alleged “Defendants jointly and severally executed and delivered to Plaintiff” the note in question, a copy of which was attached, and sought recovery against each defendant, “jointly and severally.” In the absence of any special exception by appellant, such allegations were clearly sufficient.

Concerning the sufficiency of the summary judgment evidence to support the liability of Gose, individually, we point out the following provisions of the note:

1. Only Retamco, Inc. is designated as “maker” in the heading of the note;

2. The body of the note provides:

(a) the “maker and each surety, endorser, and guarantor waive all demands for payment, presentation for payment, notices of intention to accelerate maturity, protests and notices of protest”;

(b) “Each maker is responsible for the entire amount of this note”;

(c) “The Terms Maker and Payee and other nouns and pronouns include the plural if more than one.”

3. The note was signed in the bottom right hand corner:

Retamco, Inc.

By Steve Gose (signed)

Steve Gose (signed)

Individually — Steve Gose

Appellants’ argument is twofold: (1) the note “imposes no obligation on any party other than the ‘Maker’, i.e., Retamco, Inc.” because “the clearly expressed terms of the Note is to obligate only the party identified as the ‘Maker,’ ” and (2) Gose was acting as an agent for a disclosed principal and is therefore not liable on the note. We disagree with both contentions.

Section 3.118(5), TEX.BUS. & COM.CODE ANN. (Vernon 1963) provides:

Unless the instrument otherwise specifies two or more persons who sign as maker, acceptor or drawer or endorser and as a part of the same transaction are jointly and severally liable even though the instrument contains such words as “I promise to pay.” (emphasis supplied)

Therefore, since the instrument did not specify otherwise, Gose is liable as a maker. Riley v. First State Bank, Spearman, 469 S.W.2d 812 (Tex.Civ.App.—Amarillo 1971, writ ref’d n.r.e.). If Gose signed in a capacity other than maker (since the note did not specify otherwise) he had the burden of proving such capacity. Caldwell v. Stevenson, 567 S.W.2d 278 (Tex.Civ.App.—Austin 1978, no writ). As stated by the supreme court in Seale v. Nichols, 505 S.W.2d 251 (Tex.1974):

Nichols’ asserted defense is that he signed the note, not as an individual, but as a representative of Mr. Carl’s Fashion, Inc. This defense is one of avoidance as it does not attempt to negative a necessary element of Seale’s cause of ac-tion_ Defenses in avoidance are expressly made affirmative defenses by Texas Rule of Civil Procedure 94.

In a summary judgment proceeding, the necessity of supporting a non-movant’s affirmative defense by proof raising a fact issue is well established in Texas..... Consequently, in order for Nichols to avoid a summary judgment for Seale, his affidavit must have presented evidence raising a fact issue on the ele-' ments necessary to his affirmative defense.

In this case neither appellant pleaded an affirmative defense or submitted any evidence which would raise a fact issue on the elements necessary to any affirmative defense. Consequently, summary judgment was proper. Appellants’ first point is overruled.

In their last two points of error, appellants contend the trial court lacked jurisdiction since 1) the copy of the pleadings served on them lacked opposing coun- *522 seis personal signature on the certificate of service and 2) the copy of the motion for summary judgment allegedly lacked a certificate of service. The filed copy of each instrument bears the signature of appellees counsel certifying a copy was delivered to opposing counsel. This is in compliance with the rules. Appellants’ last two points are overruled.

The judgment of the trial court is affirmed.
