no, your dad should NOT sign the papers.... you and your dad (and any other of your sibligs) should get a lawyer and come to terms with any of the issues here, and its easiest to do that with a representative that knows how to deal with it. its only fair. its not about trying to hurt them, its about trying to be fair, and just because your mother died earlier than others, doesnt mean that your family should lose out on family memorabilia, especially since the legal documents are already in place to pass down to your family whatever.... you know??
get proper representation, and go forward from there. in times of death, there is always issues like this, and it is more selfish of them to assume that your family shouldnt get anything simply because of your mother's death! this is a HORRIBLE way for them to treat your family.
just try to proceed legally, and simply. get representation, go through things legally and fairly. if possible, make sure that the legal representative gets you the things to which you are entitled before the situation is completely resolved.
i repeat DO NOT sign ANY document they may give you until you have proper, intellegent legal representation.
good luck, and im SO SORRY that you have to go through this now. what a horrible way to deal with death in the family but by having this kind of disagreement. my moms whole family hated her after their father's death and the quick claim handing over of the home to my mom. they paid the bills on the home, paid to have it cleaned up (over ONE TON of garbage hauled away) and they did all the work sorting through and separating and giving items to those who wanted different things.
when the house finally sold (it was a beautiful location on a secluded lake but it still wasnt much - i think 80,000 to split between 6 kids, and many grandchildren).... a few of the siblings chose to have hurt feelings and anger because of the amount they received.
when the house sold, my parents took record their dad had kept every time he borrowed money to all the kids, subtracted that amount from the appropriate kids... and gave them what was left - each grandchild got a smaller sum as well, all of the grandchildren got equal amounts - whether or not the CHILD actually got the money is unknown - but of course , if you only had one kid, there was only one kids share... blah blah.
anyway, i spent mine on college :P
either way, it was HORRIBLE, i have cousins now that i hardly know at all, and very tense relationships with aunts and uncles that i previously loved. i had nothing to do with the arguements, but i certainly was involved.
i guess the point in sharing this story is to help you feel better knowing that unfair hurtful situations happen a lot when there is a death. its SO unfair that you are trying to deal with your emotions when at the same time you have to deal with seemingly unemotional even hurtful reactions from family. i sympathize with you, ive seen what it does to family.
anyway.
ive blabbed long enough. i hope thigns turn out better for you - i hope you can get what you feel you are entitled to and resolve things. get a lawyer (which is in NO WAY an aggressive act - it is defensive - you are protecting your legal rights!!! your grandparents may very well have not removed your mother from their will BECAUSE they WANTED your family involved!!)
anyway.
good luck good luck good luck!
