87 yo MIL hasn't been able to drive for 10 yrs. Family kept her car for her "because she loves it". Now a niece is caring for her (for pay) & has requested $25K for a new Jeep because she says it's easier for my MIL to enter & get out of...a JEEP?!?! (Niece has had Jeeps twice before & loves them). She says she will drive her to FL 2x/yr, but MIL's health isn't good enough to ride, she must fly. MIL has dementia & isn't competent to make a contract, yet they say the car will be in her name (she won't comprehend). My husband & the other trustee agree on sending the money to them (niece is home visiting her parents & buying there). I think the girl should buy herself the Jeep, then should charge the trust for expenses when using to transport my MIL else it 's unethical. Am I wrong?
