How to split money between kids/stepkid

Thank you everyone for your input! The only reason I would desire to split the house proceeds between all the kids is because my husband and I have BOTH put in money to renovate/upkeep the house. We took what all you said and my husband and I first had a discussion and then we had a discussion as a family. Every child is applying to schools of good fit that also span a variety of prices. We came to the agreement that we will match from the home sale the dollar amount that my ex will give to the triplets. (So if my ex gives 10 thousand per kid, then my stepdaughter will get ten thousand from the house sale). Once all the kids decisions get in, we are again going to sit down as a family and talk about it. If extra money is needed for some kids but not others, we can discuss possibly using the house sale to close the gap. If it is not needed, then it will go straight into our retirement fund! My husband 100% views the triplets as his own and wants to help fund their futures, we have been married long enough that it isn’t “his kids” and “my kids”. I only referred to it this way in this post to make it easier to keep track of which kids were being talked about. Hopefully our son and daughters all get in to a place where they will be happy. And I hope that all of your kids do the same!

@PoohNDisney I like your idea of 50% to the daughter and 50% to my husband to do as he pleases. Will for sure be bringing this up to my husband!
