Making a will with a blended family

[~clover~]

My DH has told his father he doesn't want anything out of his will.
Out of the 4 kids only the 2 youngest are FILs, but he wants to give them all the same.
DH thinks its not fair & feels like he's taking away from his brother & sister.

But then if something happened to MIL & FIL, I'm pretty sure we'd take responsibility for the others anyway, so the money would go back to them in the end I guess.

BTW - FIL has always treated the kids equally. He is DHs father, & DH & his brother are FILs sons. & he is a very proud father of both of them. Always talking them up. You can just tell when he talks about them that they are just as much his world as his own 2 kids.
