Permanent alimony is insane, as is alimony over 10 years IMO. Especially when coupled with assets split 50/50. One, or the other perhaps, but not both.
10 years maximum alimony & 1/2 of assets acquired during the marriage in CA. As of 3 (?) years ago alimony is tax free. It’s hard to get both alimony and child support, but some do. Most don’t get it for all 10 years. Marriages that end in divorce last for a median of 8 years.
