I am not represented by attorney. Ex's attorney presented me an option of making a single transfer of approx $286K from my 401K to my ex's account, instead of filing 8 separate QDRO orders. It states gains/losses for the $286k would be calculated from valuation date (Feb 2019) to date of segregation. Further, the proposed order only mentions my 401k account and not the other seven accts involved in the calculation. If states that gains/loss will be calculated from valuation date to segregation date, and based only on my 401k acct. All the CP and SP property was calculated previously. My ex has 4 of the CP accounts and I have the other 4 CP accounts. My ex's 4 CP accounts have 3 years of realized gains too, but they are not being calculated into the future $286K payment. My other 3 CP accounts experienced lower gains. The $286k represents an equalizing payment between both parties 8 CP accts (401k, IRA, etc), which included tracing. All experienced different rates of return. Should all CP accts with gains/losses after the "valuation date" be used to adjust the equalization payment vs just one CP acct? How should this be handled?
