One sibling wants to contest guardianship plans. Any advice?

Co Guardianships are usually a bad idea. Offer him the one he wants, with the other as a standby guardian. If you cannot come to agreement, the Judge will appoint a guardian that HE likes and you will all be out in the cold.

not constitutions, petitions. How the heck do these spell checkers work anyway?!

USAPositive,
I filed the guardianship and conservatorship constitutions with the court because I had been trying to get siblings to agree to at the very minimum hire a geriatric care manager. They would not agree and would not respond to requests from my attorney even. So, I got fed up, changed attorneys to one known well in my area as an excellent litigator, she would have shredded sisters attorney. Once the petitions were filed, sisters attorney dragged her feet as long as possible, then two weeks before court, after hearing nothing for two months after the filing, wanted to go to mediation. In my area nothing will be heard in court if there has not been honest effort to mediate. So, off to mediation we went. Sisters finally agreed to impartial third parties to watch over mom's welfare. Then the mediated agreement had to be approved by the court, which went off without a hitch once sisters attorney stopped screwing things up. That was just a month ago but after two years things are finally beginning to happen.

The third party was not a friend or anyone any of us know. I would recommend that the person is not a friend because so many strange things could happen that would strain the friendship if not end it entirely. Strange things could happen with a stranger as well, but those that are usually appointed have good reputations with the court. And if evil brother does not like the person you have in mind maybe his objections would be lessened with someone completely neutral that is not familiar with your family.

gladimhere, was the impartial 3rd party you mentioned appointed by court (a stranger) or a family friend??
yes, we are working w/ a lawyer who is a good friend of one of my (good) siblings, he actually knows all of us, and would not be charging, he mentioned that there's a unit in court that mainly deals with these issues should one person contest, the evil brother sent him an email (copied all of us) noting that he does not give consent to what the rest of us have agreed to, this just happened, in the end the only people suffering are my parents, he's an utter disgrace

You must be working with a lawyer, right? Have you asked this question of him or her?

We needed an impartial third party because of issues between siblings in this case it was two that are in the area, but completely detached and do not understand mom's needs. In my state, by law, the POA is appointed unless there are compelling reasons not to do so. In our case there were many reasons and was the best thing to do for our parent. It will keep disagreements to a minimum.

honestly i don't know how he could live with himself knowing there's a possibility of an independent court appointed person making decision for our parents, so disheartening
