If you pay off a mobile home and they will not give you a title is it legal for them to contact the Treasurer''s office/not dmv

I am having trouble understanding your question.  If you bought a mobile home and financed it through a credit union or a bank or similar financing company, they lender normally records their lien on the title, and holds the certificate of title in their possession .  Once the loan is paid in full, they should release the certificate of title to you with the original note marked paid.  I do not see how a Treasurer's office would have anything to do with this situation, unless they also filed a deed of trust on the home, in which case they may cause a release of the Deed of trust to be filed in the local circuit court records.  That method is often used once the wheels are removed and the home is attached to real estate.
