Mom's dementia is worse & has moved to a retirement center. I have just moved my mother to an apt in a retirement center--which is twice my mother´s social security benefits. My sibling has convinced my mother, who has recently suffered a mild stroke, that the best solution is for him to move into her house and pay her half of the going market rate for rent. I have expressed that I am not in agreement with this arrangement-- that mom needs to get going rent to offset her increased living costs and home maintenance. I would like to know what kind of professional &/or legal help to seek. thank you!!
