Being mom's guardian/conservator will not stop APS from coming out every time your squibbling makes a report to them. APS is required by law to investigate all reports. APS cannot just ignore the law just because your squibbling keeps calling them.
Depending on one's state is what term(s) are used.
Guardianships/Conservatorships can be limited (over either the person or the person's property) or plenary (over both the person and the person's property).
The court ordered appointment will state guardian/conservator of the person, guardian/conservator of a person's estate (property), plenary guardian/conservator or guardian/conservator of a person and person's estate.
Some states use conservator of estate when the court appoints an entity (i.e. bank) rather than a specific person. Some states use conservator for adults and guardian when the person is a minor. Also in cases of minors, the minor will have appointed guardian of the person and consevator of the minor's estate (i.e. when the minor has assests awarded via being a beneficiary).
You stated on another thread that mom has dementia. Due to all the chaos and the judge dismissing a guardianship case your squibbling started, it is apparent that (at that time) the judge determined that your mother is competent.
You and mom can check into a voluntary guardian/conservator over her estate. Getting the deed changed back is going to require an attorney. Find one that specializes in elder abuse.
P.S. Squibbling = squabbling sibling.
Until you are appointed by a court, you are neither mom's guardian nor conservator.
