How to add someone to title after close of purchase

[Richard V.]

I am in escrow to purchase a condo. I wanted to add someone to title but seller forgot to inform his attorney and he says to do so now would delay close of escrow. He recommended I do a quit claim to add her to title after close of purchase. Is this ok? Did not want to trigger loan to be due in full if this were to take place. Any advice would be appreciated!
