I've meditated on my sister's situation
and come to the conclusion that there are
presently no legal issues requiring attention,
and that future issues ought not be anticipated,
because they can and should be managed
when and if they occur.

There are two potential sources of difficulty:

1) Margrit's applying for and receiving public
assistance of any sort on the representation that
she was indigent. So long as we are in reasonably close
contact with her, this would come to our attention,
and as soon as it did, we would immediately intervene
by repaying any sums that she had received and by preventing
the disbursement to her of further public funds to which,
because of assets belonging to her, she was not entitled.

2) Margrit's applying for and receiving non-government
loans. Her liquid asset trust funds cannot serve as
collateral, because of the statement on the face of 
every accounting that third parties have no recourse
to the funds. Her real estate trust assets cannot serve
as collateral because they have no market value.
Because of her age and mental status any contract 
that she might make is subject to rescission, as was
Aunt Nannie's purchase of gold coins.

Given these circumstances, I consider the family
real estate assets to be absolutely safe. These assets
would be vulnerable only if she had received public
assets on the misrepresentation of indigence. This
is the one and only contingency which you and I must
not permit to happen.

What is most important to Margrit is her illusion of
being "independent" of her family, and of the fidelity
of the "friends" on whom she thinks she can depend.
It's not desirable and certainly not necessary
that she be disabused of these illusions at this time.
Everything that we say and do should be aimed at creating
and maintaining a relationship of trust that will provide us
with the information to enable us to intervene in her
affairs in timely fashion if and when the occasion arises.
