my atty mistakenly did a QDRO on my 401k, and not my pension plan... do i need another QDRO to get back the half of the 401k given to her? or do i just need some sort of signed affidavit from her  to get it back? ...   and to be sure, do i really need a QDRO to split my pension? or how else could it be done..we are not having the court do our property settlement..we are doing it ourselves...
