How can I obtain a re-entry permit in Thailand if my landlord is registering me online?

I need to obtain a re entry permit for my trip out of Thailand. I reside in Phuket on a retirement extension. When I went to Phuket immigration, I was told that i was registered in another province(probably because of many recent hotel stays in Bangkok). They asked me to obtain a copy of my landlord's id card, a copy of her tambien baan and to fill out and sign the "notification from house master" form. When I informed my landlord, she was adamant that none of this is required and that she will register me online when she gets home from work tonight. Will i be ok to go in tomorrow and obtain the re entry permit, providing she registers me tonight. Or do I physically require the documents that i was told to obtain. I am panicking as i fly out in 2 days time.
