JAFO to Hawkin: <<<Also, your solution does not address son and daughter both surviving OP and son dying and leaving his half (or what is left of it) to whomever sons desires. Seems son’s half should almost be in trust to assure that any left-over goes to daughter or her children, though son may need some limited power to invade corpus either with consent or for health, safety and welfare. BWDIK?>>>
“I get your point but in my case, I am not too concerned with controlling my sons slice after he receives it.”
“But I do have two considerations. First, if he predeceases me, , then I want his slice to go to my daughter. Second, if he is missing or uncooperative, I don’t want that to impact or delay my daughter receiving her slice.”
Understood.
“Note that am using the term slice rather than half. I am not clear if per stirpes will allow me to implement asymmetric splits.”
I am not familiar with the Vanguard paperwork, but generally speaking per stripes does not allow for asymmetric splits - it is usually 1/2, 1/3, 1/4depending upon roots/branches.
“That is another element that may drive me toward moving some assets to another custodian. I would prefer to just split into two unique account, both at Vanguard, but their system is clear, their beneficiary designations operate at the account TYPE level. So two Roths with them would not allow me the features I am looking for.”
If you do two accounts, just be aware of your investing strategy. I recall reading about a father who started a UGMA accounts for his two sons, and in one he bought Microsoft and some other then-hot tech stock and a few years later one son had stock worth $xxx,xxx.00 and the other son had stock worth $x,xxx.00 Dad did not buy each stock in both accounts to avoid two extra trade fees and was now looking for a way to legally equalize the values.
It was a shame it was not 529 accounts he owned because he could have moved the money easily, but they were UGMA accounts. Moving the money would be theft. And he did not have sufficient additional funds to contribute to the second son to equalize the accounts.
You do not want your son to hit the lottery with your best investment choices while your daughter gets the ones with average returns.
