This depends on who owns the property. If the property is yours then no registration required Do you have permission, Then no registration required. Other wise yes it must be registered
Yes
yes
Only if you have a lien on it.
The state doesn't repossess your car - private companies do that on behalf of the lienholder. They don't charge you for private property left in your car when they repossess it - that would be illegal. They charge a "storage fee" for the items they remove from your car. Underhanded, yes, but they can legally do it.
No, they are allowed to come and take it away.
YES, if there is no breach of peace
Used from a private party.
From my Experience All you really need is a written Contract on the said property, Dealers, Used car lots, and Banks register the property financed so it shows the lien on the title. Private sales with money owed if you have a written contract you can repossess on site. if this is an oral agreement, You will have to go through the small claims division of the county courts
That is a private matter.
As a private citizen, you can't.
It is against state law to open a locked gate.
