401k to Roth IRA conversion

[summer2007]

I'm trying my best to help my Dad out with his 401k to Roth IRA conversion.

He has both his 401k and Roth IRA with Vanguard.

Right now after talking to a few people at Vanguard they have him a little confused.

The guy he was talking to last was telling him that whatever amount that he wants to convert that they send my Dad a check for that amount and then he sends the check back in to Vanguard to be put into his Roth account??

I thought they would just transfer the shares that he holds in his 401k over to his Roth IRA?

Does this sound right to others that have converted from a 401k to a Roth to have a check sent to you and then you send it back to put in your Roth IRA?

Thanks

Jim
