I just noticed a typo in the address on a rental agreement I already signed, and I only have my iPhone with me until tomorrow. The PDF seems locked now that my signature is on it, so is there any trick to making quick text changes directly from a phone without starting over? ---

had the same thing last month on a form i already signed. tbh i don’t think you can actually change the text on an iphone once the pdf is locked like that, files app markup just lets you scribble on it. i’d wait till tomorrow and fix it properly or just tell the other person about the typo. not worth messing with a rental agreement from the phone. ---

Editing the PDF after signing will usually invalidate the digital signature. Ask the landlord to correct and resend it, or add a signed amendment, then re-sign on the iPhone. Avoid covering the typo with Markup, since that only hides the text and can look like tampering. ---

A signed PDF is meant to lock the document, so changing the address will normally invalidate the signature. On an iPhone, I would avoid trying to edit the signed copy and ask the landlord or agent to send a corrected version for everyone to sign again. If it is genuinely urgent, you can add a note or annotation, but that is not the same as correcting the signed agreement. ---

I wouldn’t unlock the signed copy, since editing it can invalidate the signature and cause problems with a rental agreement. From your iPhone, ask the landlord or agent for a corrected PDF or a short addendum you can both sign, using Markup in Files or Adobe Acrobat. Markup can also add a quick note, but I’d treat that as temporary, not the correction. ---

I’ve had this with supplier forms. A signed PDF is normally locked to protect the signature, so I wouldn’t try to alter it; I’d ask the other party for a corrected copy or add a clearly agreed correction and have everyone initial it. ---

Editing text on a signed PDF usually breaks the signature anyway, so honestly the quickest fix is to not fight the lock. Make a backup copy of the signed file first, always. 1. Open it in Markup (Files app or Mail), add a text box over the typo with the correct address, flatten/save as new file. 2. Don’t try to delete the original text underneath, you’ll mangle the layout on mobile. 3. Best bet is still asking whoever needs it to let you send a short note or initial the correction rather than silently editing a signed document. ---

That locking feature is so annoying when you just need to fix one quick typo. We get this constantly with signed field reports at my construction job, and you basically have to strip the signature first. I usually open [pdfcap.com](http://pdfcap.com) on my phone and tap the flatten tool to save a new unlocked version. Then you can just change the address text and sign it again. ---

@guest_996848, I get why that works for quick field reports, but a rental agreement is different. I’d rather not strip the signature on a phone, since it could look like tampering later. Safest is a corrected copy or a short note you both initial. What device are you using? ---

@ClumsyRed honestly yeah, locked pdfs are so annoying once they’re signed. we run into this constantly with patient consent forms at work and the iphone files app just won’t let you touch the underlying text. definitely safer to have them send a fresh one to sign.
