Legal Question in Wills and Trusts in Texas

Not much of what you've been told is true. First, your brother isn't the Executor yet if your father is still living -- and he won't be until the Will is admitted to probate. Why he feels compelled to have an attorney advising him regarding a potential future fiduciary position is his problem. As for things that you gave to your parents as gifts -- you gave them away. Getting them back shouldn't exactly be expected, but I can understand that these items may have emotional significance to you that far outweighs their monetary value. Same with the things that your mother gave to you (assuming that you can prove the gifts were made.)

All in all, you're hearing what your brother interprets, and I wouldn't place too much stock in it. It demonstrates some pretty fundamental misunderstandings on his part, however, which should be a pretty clear signal to you that you'll want to retain your own attorney when the time comes.
