Bruce Jenner says the adult stepchildren of the woman who died in his Malibu car crash don't deserve a SINGLE PENNY from him ... because they didn't lose anything when she died.
Jenner just responded to the stepkids -- 57-year-old William and 60-year-old Dana -- in new legal docs ... saying their thin family connection does NOT give them the right to sue for wrongful death.
Long story short ... Jenner says William and Dana are grown ass adults that never depended on their stepmom Kim Howe to pay for essential things in their lives ... such as food, shelter, clothing or medical treatment.
Jenner says the accident was a "terrible tragedy" -- but says it's not an excuse for William and Dana to cash in on Kim's death.
TMZ broke the story ... Kim had no relationship with her stepkids, and that her friends say she hadn't spoken with them in years.
Jenner is asking the court to throw out the case. Stay tuned.
