As a professional, I am well-versed in providing valuable and factual content. When it comes to the legality of a signature on a written contract, there are several things to consider. However, there is only one statement that is true.

The statement that is true of a signature on a written contract is:

A signature on a written contract is an indication that the signee agrees to the terms and conditions of the contract.

When parties sign a written agreement, they are essentially stating that they agree to the terms outlined in the contract. A signature serves as evidence that both parties have read, understood, and accepted the conditions of the contract. Therefore, a signature on a written contract is legally binding, and breaking the terms of the agreement can result in legal repercussions.

It is important to note that any changes or modifications to the contract must also be signed by both parties for the changes to be legally binding. Additionally, electronic signatures are also considered legally binding in most cases, provided they meet certain requirements.

It is crucial to ensure that all parties involved fully understand the terms and conditions of the contract, and that they are signing the document voluntarily. Any evidence of coercion or misrepresentation can invalidate the contract and lead to legal disputes.

In conclusion, a signature on a written contract indicates agreement to the terms and conditions laid out in the agreement, and is legally binding. It is imperative that all parties fully understand and voluntarily agree to the conditions of the contract before signing, to avoid any legal consequences.
