Anyone here familiar with "Family Trusts"...?

1. The trustee is the person who makes decisions about the trust.

So someone should be designated as the trustee. Generally, it’s husband/wife then someone else. If it’s still under your Dad you’d need to get something from his doctor saying he’s unable to make those decisions. At that point whoever is designated trustee can make those decisions. They are required to abide by the terms of trust as to who gets what.
Property in trusts can vary state by state. Florida, May it may not, recognize property in a trust. Seems to depend on who you ask.
