How can I find out details about the Will and Trust fund?

In order for a will (with or without a trust inside the will) to be valid it must be "proved", i.e., "probated". That requires that the will be filed in the county probate court where the decedent was living. It is a public document and anyone--not just family or those named in the will--can go down to the probate court and have a look at the will and even request a copy be made for a nominal sum.
Once you have a copy of the will in hand, read it and see exactly what if anything you were left. If the language is too hard to read, you may need to find an attorney to help interpret it for you.

In America at least, what Garden Artist said about asking the probate court is a good idea. I'm surprised Mom won't let you see a copy of the will just to put it to bed for both your sakes. A lot of times it isn't the actual $'s that are important to the child, but more it is the one sweet, last thing, that the parent did because they loved you. Kind of like a last hug after the fact. I can't imagine Mom not understanding that you need that closure, either way.

Maybe there was a trust at one time that ended up getting used for your Dad's expenses or care along the way instead. Like a "revokable trust", I think the person who sets that up can also take $ out. I am supposedly on some sort of revokable trust of my Father's. I don't expect to see a cent though. He married a lady we hardly know in a different part of the country, she never comes back with him to visit family. He's made a ton, bought her a beautiful new paid for house, new car, cash, has a pile in savings, added my Grandparent's pretty healthy estate to that a year or so ago. They set up a trust with all my family's $, for me, and her 4 grown kids, (who I've never met), to divide equally. This is going to take place after he goes, and then she goes. Isn't that special? :-) This whole thing was cooked up right after my Dad had a brain bleed from a car wreck, he doesn't think right anymore, and she knows it. So at least I know my Dad didn't leave me out on purpose, which will help when the time comes. It would really hurt to think that he didn't think of me when I am missing him. I sure hope you find out something.

Almost wish there were a national "prepare you will, pass out several copies" day. :-) Would sure save a lot of grief if everything was above board and common knowledge for all involved. Take Care.

marcolorenzo: check with your local courthouse. they will be able to tell you if a will must be filed with them. I found out that my father filed my mom's 'original' Will at our country court house when my mom died 21 years ago, LONG before hey had acquired certain properties and received two huge cash settlements. Even her original will had items and cash going to me and my sister. No idea what her new will stated. I found out that both mom and dad had new wills made after buying real estate and getting large lump sums of cash. He knowingly filed the old will and only told me and my sister 'no need to see the will, you mom left everything to me'.
I found out too late after my dad accidentally said something about new wills being made. Statute of limitations had run out by then.
And I want to STRONGLY point out that this was your DAD's will, not your mom's will to do with what she pleased.
If you were left anything, even a token watch, a ring, a special coffee mug, it doesn't matter, because anything you dad's Will said was for you, then it is YOURS by rights.
That Will is HIS final wishes, not hers to determine yes or no.
Years later I confronted my dad and asked 'why did you lie to me and my sister? why didn't you honor your own wife's Will, why didn't you give us what mom wanted us to have?' and he simply said "Because I wanted it ALL".
For a spouse to knowingly disregard a deceased spouse's final Will is to disrespect those last wishes.
It is not for them to choose, that is WHY there is a Will.
I hope you get to the bottom of this quickly.
Not sure about your area, but a Will filed at our court house is public information and you only pay a small fee for a copy of the Will.
If you know your dad's attorney, get in touch and ask. They may know if they drew up the Will for him.

Marcolor......Unfortunately, we have to trust that the Will was carried out. If it was a Probate, you should be able to find something, but it does not sound to me that it was a probated estate. When my mom was dying her concern was that my siblings would be at the house at that very moment taking what she had wanted me to get. I felt so sorry for her. I trusted my siblings. For some reason, I was the Trustee until the last two weeks when my brother suddenly became Trustee. Well not to bore everyone, end result, I got a small financial piece but nothing in the way of my mom's precious items. My sister runs around with beautiful diamond rings and has no guilt in the matter. My brother will send me copies of photos of me growing up, but no originals from my mom's photo books. My husband wanted me to sue them, but I just put is aside and felt that God would take care of the matter. I did not need the added stress and I loved my mom SO much. I was alone with her and those were the most precious moments. I never saw the Will or the Trust.

When a person dies, everything goes into probate--a Will shortens the process. Now if the deceased's wife has access to the bank account, it's a moot point. It is saddening you see how greedy people are when someone dies they circle like buzzards waiting for a piece of the pie. ALL of them do it.

It doesn't sound like the OP is in the United States, from the writing style.

Normally in the US you could easily find this out. Those mentioned in the will/trust are notified as well. It's up to the executor to get them what they're entitled to. For example, if you're left $10,000, you're notified and you get the $10,000.

The cousin could be just talking.

my fil's estate was not probated; mil made granddaughter, who she considered as a daughter, even though they never adopd her, her POA, closed out fil's safe deposit box, which supposedly younger son also had access to but in waiting until after funeral to use, by then when it went had all been done and had been told there were papers in it with instructions for him and things to be left to him but had been moved to new box in mil's a gd's name, with him having no access. They also went to the attorney to finish the drawing up of the deeds for all the kids, except he'd made sure they had theirs without telling mil and gd, so they couldn't find theirs

Is it advisable to have a Pour Over Will along with the Trust?

Our wills are if I go first DH gets all and visa versa. Once one of us is gone the survior will get a new will. At that time things will be left.

OG, yes, that's my understanding. The Pour Over Will has language linking it to the Trust.
