Deed Lacks Grantor Signature
Sierra Santos prepared a deed conveying her cabin to Sean Steele. She wrote the names of the parties and the property description but never signed the document before handing it to Sean. Sean recorded the deed and later claimed title. The court held the conveyance invalid because the grantor never executed the required signature.
Revenue Bill Awaits Signature
The House passed a revenue bill and sent it to the Senate, which added amendments and returned it. Both chambers approved the final version and presented it to the President. The President took no action for nine days. The bill became law without his signature because Congress remained in session.

Sasha Stone, an unrepresented plaintiff, filed a complaint in federal court but omitted any signature. The defendant moved to strike the pleading. The court ordered Sasha to correct the omission within fourteen days. When she failed to sign, the court struck the complaint from the docket.
Contingent Fee Agreement Unsigned
Sarah Sullivan retained Sterling Manufacturing's counsel on a contingency basis for a products liability suit. The lawyer sent a written agreement stating the percentage fee and expense allocation but never obtained Sarah's signature. After settlement, Sarah refused to pay the contingent share. The lawyer could not enforce the fee because the client had not signed the agreement.
Lease Missing Required Signature
Steven Silva agreed orally to lease warehouse space from Southland Foods for three years at a fixed rent. The landlord prepared a writing identifying the parties, premises, term, and rent but signed only its own copy. Steven never signed. When the landlord later sought to enforce the lease, the court held it unenforceable against Steven because he had not signed the memorandum.
Removal Notice Lacks Signature
Sylvia Santos, defendant in a state-court contract action, filed a notice of removal in federal court. The notice contained a short statement of grounds and copies of all served papers but bore no signature. The plaintiff moved to remand. The court struck the unsigned notice and remanded the case because the removal statute requires a signature under Rule 11.
Common questions
Frequently Asked
4
Does an electronic signature satisfy the signature requirement?+
An electronic sound, symbol, or process attached to or logically associated with a writing and executed or adopted with intent to sign satisfies the requirement in most jurisdictions and under the cited rules.
Supporting sources
What happens if a required signature is missing from a deed?+
The deed fails to satisfy the statutory requirements for a valid conveyance, so title does not pass even if the document is recorded and delivered.
Supporting sources
Must every party to a lease sign the memorandum?+
Only the party to be charged must sign. The lease remains enforceable against that signer even if other parties have not signed.
Supporting sources
Can a president allow a bill to become law without signing it?+
Yes. If the president takes no action within ten days while Congress is in session, the bill becomes law without signature.
