in general, if you have a lease

with one person signing the lease, your petition is against this person. the court notification should be addressed to this individual. However, when you get a warrant, it should be given to this person and all other occupants.

If the lease has two individuals, you need to have two separate services to deliver court paper. The warrant should be against to both individuals. But for the warrant service, you still have to have two separate services.

A lot of paperwork that you can make a mistake. Hire somebody to do all the work.
