questions regarding leased owner opereators

I have some guys leasing onto my company and was curious about certain things i got the insurance all setup lease agreements signed the only thing left is to get the apportioned plates. they require truck registration do that have to register in the same state as the tags or can they register in there home state. can the registration state be different the apportioned plates

 

OK but if my company is in say louisiana and the owner operator is in Oklahoma can they register and get plates in Oklahoma if so does the owner operator get his own irp account or do I have to get one in that state also would I need a certain power of attorney to allow driver to do that

 

ok so if i understand correctly operating in LA if i purchase base plates i have to do it in LA but driver can purchase in his state with a power of attorney from me stating he can do it correct? or am i still missing something

 

ok so suppose i have to plate them in la for those that cant afford it that means i would also have to register there vehicle first so whose name to i do it in also if a lender is holding the title would i put it in there name the buyers name or my companies name how would i do that

 

ok so i wont need anything to register it in someone elses name?
