Do all children HAVE to agree to POA?

In most cases, all adult children must agree to a Power of Attorney (POA) if it involves decisions about shared property or finances, particularly in cases where they are joint owners or beneficiaries. However, if the POA pertains solely to one child's authority to act on behalf of a parent without impacting the other siblings, then the consent of the other children may not be necessary. It's essential to check state laws and consult with a legal professional for specific situations.
