so i went to the doctor that my mother has been seeing for years, i asked the doctor of my mothers cognitive ability to sign any legal documents. The doctor stated that my mothers diagnosis under her care does not have the ability to do so for over 3-5 years of her care. Can my brother still try to execute his part to carry out the will due to my mothers cognitive inablilities
Do you care about what's in the will? Are YOU a beneficiary? I know so many piously write that "it's not about the money," which always puzzles me when most of them then describe their bad financial situations because of their caregiving slavery.
I hope your mother is compensating YOU for your caregiving now. And at a good rate. If not, then it seems like your brother has possibly pulled a fast one on you with the will.
Don't you want to extricate yourself from your caregiving situation?
Did you Mother also have prepared a Power of Attorney for her health decisions and finances? If not, it's too late to have that done due to your Mom's current dementia stage.
A Will cannot be put into effect until your Mom's passes, then it is up to the Executor to handle the Will. The only way your Brother can carry out whatever he feels needs to be done right now would be if he had Power of Attorney.
