(a) Signature. Every pleading, written motion, and other paper must be signed by at least one attorney of record in the attorney’s name—or by a party personally if the party is unrepresented. The paper must state the signer’s address, e- mail address, and telephone number. Unless a rule or statute specifically states otherwise, a pleading need not be verified or accompanied by an affidavit. The court must strike an unsigned paper unless the omission is promptly corrected after being called to the attorney's or party’s attention.

In one sentenceRule 11 requires every pleading, motion, and paper to be signed by an attorney of record or an unrepresented party, and treats that signature as a certification that the filing isn't made for an improper purpose and that its legal and factual claims are supported or have a good-faith basis.
Full Text of Rule 11
(b) Representations to the Court. By presenting to the court a pleading, written motion, or other paper—whether by signing, filing, submitting, or later advocating it—an attorney or unrepresented party certifies that to the best of the person’s knowledge, information, and belief, formed after an inquiry reasonable under the circumstances:
(1) it is not being presented for any improper purpose, such as to harass, cause unnecessary delay, or needlessly increase the cost of litigation;
(2) the claims, defenses, and other legal contentions are warranted by existing law or by a nonfrivolous argument for extending, modifying, or reversing existing law or for establishing new law;
(3) the factual contentions have evidentiary support or, if specifically so identified, will likely have evidentiary support after a reasonable opportunity for further investigation or discovery; and
(4) the denials of factual contentions are warranted on the evidence or, if specifically so identified, are reasonably based on belief or a lack of information.

Plain-English Summary
Every pleading, written motion, and other paper needs at least one signature — an attorney of record's, or the party's own if unrepresented — along with the signer's address, e-mail address, and telephone number. Unless some other rule or statute says otherwise, a pleading doesn't need to be verified or backed by an affidavit. If a paper comes in unsigned, the court has to strike it unless the omission gets fixed promptly once it's flagged.
Signing, filing, submitting, or later standing behind a paper is also a certification. The person presenting it is telling the court that, after a reasonable inquiry, it isn't being filed to harass anyone, cause needless delay, or drive up the cost of litigation; that its legal arguments are supported by existing law or a good-faith argument for changing it; that its factual claims have evidentiary support (or will, after a reasonable chance to investigate or take discovery); and that any denial of the other side's facts is grounded in the evidence or a reasonable belief.
