Hi
@Rayreadynow , you ask this question regularly. I think you might be confusing tax rules and gifting and POA rules and gifting. . Someone can gift their own money under tax rules . There are limits and rules but they are entitled to do so under those rules.
A POA can only gift if it is the donors normal gifting pattern and the amount is reasonable and in their best interest .So it could be acceptable and be said to be in their interest to make a small gift to,say grandchildren, for a birthday or Christmas gift or wedding present.in their interest to maintain a family relationship. But it is not permitted to gift large gifts. As a PWD is likely to need money for their care it would be deemed deliberate deprivation of their assets.
A POA has to spend in the best interest of the the donor and with dementia the donor is likely to need that money for their own care.
