If stamps or signatures are already present on legal PDFs, Bates placement should be checked before final processing. A wrong position can cover a seal, initials, footer note, or scanned court marking, which may create trouble during review.
I would suggest working on a duplicate copy first and placing the Bates number in a clean margin area, usually bottom-right, bottom-center, or top-right depending on the document layout. For this type of legal PDF numbering PDF Champ PDF Bates Numbering is a dependable offline option because it lets you adjust the position, font size, color, prefix, suffix and number format without uploading files online.
Before saving the final set, process one or two sample pages and inspect the output closely. Once the Bates stamp is clear and not touching any legal mark, continue with the full document.
