Quick answer
A signature usually means agreement to be bound by contract terms. In contracts, it matters because failure to sign can make the agreement unenforceable. Before signing, verify all terms are complete and acceptable.
Definitions
What is sign?
Legal Definition
A signature affirms agreement to a contract's terms. It creates binding legal obligations on the signatory. The method of execution—wet signature, electronic, or seal—may affect enforceability depending on jurisdiction and document type.
Plain-English Translation
Like signing a permission slip to go on a school trip, a signature tells everyone 'I agree to these rules' and can't later pretend you didn't know them.

| Seal | Formal authentication mark | Historically more formal than a signature, rarely required today |
| Initial | Marking first letter of name | Shows review but not necessarily full agreement like a signature |

Missing or vague
If sign is missing or vague
If the signing requirement is undefined, disputes may arise over whether electronic signatures suffice or if wet signatures are required.
Without clear signature instructions, parties may disagree on who needs to sign and whether authorized representatives can sign in place of principals.
Vague execution terms can lead to battles over whether a contract was properly formed, potentially resulting in unenforceable agreements.

Document context
How sign shows up in legal documents
Why does it matter?
Failure to properly sign a required document can render it unenforceable, with the non-signing party bearing the risk of losing contractual rights or protections.
When does it matter?
Signing typically occurs when parties reach agreement on terms but before performance begins. Execution must generally be completed within the statute of limitations period applicable to the contract.
Where is it usually seen?
Signatures appear in virtually all contract documents, deeds, and court filings. They are particularly critical in real estate deeds, loan agreements, and corporate resolutions under state law requirements.
Who is affected?
The signatory gains contractual rights but assumes obligations. Witnesses and notaries may bear liability for attesting to capacity or authenticity depending on jurisdiction and document type.
How does it work?
First, the party must have legal capacity to contract. Then, they must affix their signature to the document, either physically or through authorized electronic means. Finally, the document should be properly delivered to all parties to complete the formation of a binding agreement.
