A tenancy lawyer typically handles all matters related to landlord-tenant law, including the initiation and termination of leases and other similar tenancy contracts, evictions, issues regarding damage deposits, and other breach of contract issues. There are lawyers who specialize in commercial tenancies, in terms of leases by and for businesses, as well as lawyers who deal primarily in personal tenancy issues. Tenancy laws differ widely from state to state, so it is important that if you have a tenancy issue, you should consult a lawyer for your options. There tend to be certain strict deadlines for dealing with some aspects of tenancies, so it better to contact an attorney as soon as you become aware of a problem, rather than when it is too late to seek relief under the law.
