No, parents cannot delete or edit anything they post. All any parent can do is add to the Record. TalkingParents Certified PDF/Printed Records are intended for use in court and are not supposed to be altered in any way, and our admins cannot remove a file.
If you uploaded an attachment by mistake, please post a new message asking your co-parent not to download the file right away. Identify any attachments added in error and post a new message under them identifying them as such, so the matter is documented on your Records.
