Affidavit

I recently recieved papers from Family court. I noticed the affidavit is not written in the handwritting or grammer used by my ex, but it is signed by her as if she wrote it. Is there any legality behind this?

An affidavit does not have to be in the handwriting of the affiant. It only has to reflect a true and accurate statement of the known facts. The affiant just has to acknowledge that he/she agrees and signs as such.
