debt collection agency

I am negotiating with a collection agency and they have put a restraining notice on my mother's accounts. I have given them proof that the funds in those accounts are not mine, even though my name is on the accounts. The name was changed after my father died and only because if anything happened to my mother the family could handle the finances. Anyway, they said they would remove the restraining notice if I provided proof the funds were not mine. I did that by faxing them a copy of the bank books that clearly state that the name change took place 4/9/90. I have $5,000 to pay on my debt. It does not pay the entire debt, but I asked that they issue an income execution for the remained of the debt. They will not proceed with my check. I need something in writing stating they are goinfg to proceed to remove the restraining order and issue the income execution. Then I will send the check. How can I get them to do this. What should I write for a statement for them to sign. I think once they get my check they may not proceed in the way I ask. They have already gone back on their word. I cannot send the check without something in writing. What should I write? How do I proceed? Is it legal to hold these books?

Deceased father - no will

My father and I have been estranged for several years (I am an only child). I have just found out that he passed away in October without a will, and someone else (who I'm guessing is a relative I do not know) had already sold his house and I assume has claimed his belongings. I don't even know the circumstances under which he died or where he is buried. Do I have any rights?
