I did a partial transfer in May. Within my LC account, I withdrew the funds to Strata. I filled out the transfer forms on Vanguard's website, printed them out, and mailed them off without being notarized. About a week later, Strata said they mailed the check to Vanguard. Vanguard shows they received it a week later, and then it was another week before the funds were available for investing. Took about a month in all. Fee for partial transfer was $25. Not sure how that affects taxes. I'm thinking it probably won't.
