As Mr. Fromm indicated the trust document would specify what events would lead to termination of the trust. I would advise that you meet with a local trusts and estates attorney, who is also experienced with business succession, to review the key provisions of the trust.
If the value of the assets you are attempting to collect is less than $30,000.00 then you may be able to file a small estate affidavit with the Surrogate's Court of the appropriate county. This is a much less complex process than probate and also less time consuming. You should be able to handle it yourself by visiting the courthouse and speaking with the clerk.
The suspension lift fees attached when you defaulted on the tickets and a suspension order was entered. They do not lift in the event you later answer the ticket and the charges are dismissed or negotiated down.
As you have already been advised, you should report this to your insurance company immediately. In addition, before you contact the police you should seek out an experienced local criminal law attorney. Leaving the Scene of an Accident with Property Damage may subject you to criminal charges.
As indicated by the other answers, you should contact the clerk of the particular court to determine the fine and suspension lift fee. If you are unsure what court the ticket was returnable to, you can contact NYS Department of Motor Vehicles to order a driver's abstract. That will provide you with the information on the court that put in the suspension order.
