The letter or form must be signed by the person whose case is in question.

Please be sure to sign the letter and include your contact information.

But it was decided to leave them in and we all signed the letter.

The letter was signed by the party leader of a foreign government.

This letter will be signed by the General major and myself.

His letter was signed by 42 people, including many scientists.

The letter is signed by the president of the moon university.
