Well, first, you'd have to explain how the repossession was illegal. There really isn't any such thing as "illegal repossession"... repossession is a legal process by which a lien holder can recovery property which does belong to them in response to a delinquency of payment or violation of the contract.
A vehicle which has no grounds for repossession but was taken was not repossessed - that's theft, plain and simple, and if that's the case, then you'd file a police report, an investigation would commence, arrests would be made, and you'd either recover your vehicle or get an insurance payment if the vehicle was unrecoverable. I'm guessing that's not the case, since you're asking this question here.
State laws on time which a delinquency must continue for before seizure of assets can be made varies by state... if this law was violated, then you're going to have to lawyer up and take the legal route against the lienholder (the repossessor is not liable in this instance, as they are contractors following the instructions of the lien holder).
A criminal act on the part of the repossession agency has occurred if...
It depends on the legislation where you live
You rights are to GET IT BACK, PP is not subject to the security interest on the car.
No
They do not have to notify you. You have no legal rights regarding car.
First, you have the burden of proof it was in the vehicle. This is nearly impossible unless you have photos of it in there as they took it. Judges are not sympathetic to those repossessed as there are so many who claim valuables lost while in impound or when repossessed. You will likely not be paid anything. Sorry, but the way the cookie crumbles.
There is no way to get illegally married and then acquire any of the legal rights of marriage.
You have the right to reclaim personal property during the normal business hours of the establishment where the vehicle is impounded. The company storing the vehicle must take inventory of and proper protection of such property under the "in bailment" laws of the state where the vehicle was seized.
Not usually, but extenuating or complicated circumstances might apply. I suggest you see a lawyer or consumer rights group (like the BBB).
If the repossession occurred in a state that does not permit self-help repossession, report the car stolen; it cannot be legally repossessed. Louisiana and Wisconsin are two of these states. If you can show legal possession of the vehicle, and on time payment, report the car stolen. It cannot be legally repossessed in any state unless the debt is delinquent. If you do not wish to involve LEO's immediately, contact the private party who "repossessed" the vehicle and explain that if it is not returned within a reasonable amount of time, that you will report the vehicle stolen and give his name as the party responsible. There is no legal "personal reason" for repossessing a vehicle.
As long as you continue to make the payments, they would have no reason the instigate a repossession. When a vehicle is financed or leased, the creditor has an interest in the vehicle and rights under the contract you signed. If you are in default of the contract either by default in payment or otherwise (failure to insure or other terms) the vehicle can be repossessed.
Contact a local attorney for state/case specific advice. Please have all your paperwork and any proof of the "damages" when you do.
It depends on the state in which you reside. Most of the time, if the personal property is permanently affixed to the vechile (stereos, tires, etc), you have no rightful claim to them. Items that are loose in the vehicle such as cell phones, books, CDs, etc, have to be returned to you at no cost.
Very little ! If you default on the payments, the finance company are quite within their rights to confiscate the vehicle. The camper does not become your property until you have made the final payment !
