Accidentally used wrong iCloud - help!

[BadPoet]

I was working on some documents on my own profile on iMac at home, then tried to access them on MacBook/iPhone when out at study day and realised that the original documents had gone to dh's iCloud, not mine.

I have dh's password so was able to access it but it has now backed up everything on my phone to his (naturally) and I want to move the documents to mine then re-sync the phone to mine. But how?

Thanks oh techy wizards!
