My mom appointed me executor of her estate does this become effective after she passes on ?

My mom is currently very sick from a massive stroke. Her brother has power of attorney for all her medical decisions.My mom is not expected to recover or survive and I wish to make all the arrangements she indicated in her will. Since her brother has power of attorney will that switch over to me ( executor of her estate ) once mom passes on. I cannot do as she ask as they say I am not the power of attorney while she is alive,how does this work after she passes on ?

My mother's will appoints me she spelled it out what she wanted and who see wanted to fill that role which is me. - she could change the will anytime-She is brain dead -massive stroke and on life support I doubt she will change anything in that condition

After she passes away, it will be your responsibility to distribute her assets as she has requested.

You can make pre- arrangements, such as lining up whatever services you want to use for her funeral and so on.

It is better to do it in advance since you will not be as emotional and can make rational decisions regarding her funeral.

If you are the executor of a person's Last Will, you can not act in that capacity until the person is deceased and until you have been appointed to take that fiduciary responsibility by the probate (or similar) court. A health care proxy ends with a person's death. A financial power of attorney ends with a person's death and can not be transferred. Until you receive the official probate court appointment, you can not act on behalf of your mother's estate or manage, give away, take, transfer, dispose of or sell her property. You can, however, make arrangements as her daughter regarding her wishes that do not have to do with money or property from her estate.

Upon death, the duties of the executor begin. At this time, the power of attorney ceases to be effective.
As executor , you will work with the
administrator of the estate. Yes, your brother's responsibilities will end and your will begin.

It is a good idea to make the burial arrangements in advance rather than wait. I urge you to be prudent, only you know how much $$ and insurance there is that is available for a funeral. If the estate is large, then, be reasonable, but if the estate is small, be thrifty.

Remember, you cannot spend a dime without approval of the administrator, ( the attorney)
Having just completed this for my father, I guarantee you and the attorney will exchance many emails.

Actually, you are not the executor. You are nominated as the executor. Once she passes on, and the will is submitted for probate, the probate court judge will appoint an executor. It will probably be you, unless you are wholly unsuited for the task. That will give you certain powers over her estate. Until she passes on, however, you have no role. In fact, she could change the will anytime.

YOu can make no arrangements with the willl. Period. You execute the terms of it upon her demise. His POA is out of effect upon her death
