Yes, there's likely more to the story.
What about ANYTHING--as relates to the mentioned autistic son---gave the daughter the right to transfer a home into HER name while her father was ill and fail to so inform him of the transfer (and REVERSE the transaction) when he recovered?
What about ANY relationship made it okay to withhold that information until the statute of limitations expired?
What made it okay for them to withhold the information that the man did not even own his own house until eviction was threatened?
Sorry. I don't care how intrusive the old man was, vis-a-vis his desire to be involved with his autistic son. Really, NOTHING about that relationship is germane to the situation.
They do not have the right to exploit the man, period. I'm rather shocked at the seeming, "Well,he must've deserved it" attitude.
I watched, hands tied, as my elderly and ill mother was egregiously exploited by her father and an adult nephew. The resources for elder abuse intervention are pathetically limited, and legal recourse grievously inadequate. Make the mistake of trusting the wrong person, and you're screwed, if you're an elder in this country. "Our hands our tied" is a piss-poor excuse; it's time for some REAL changes to be made.
