N.H. Rev. Stat. § 356-B:7
No condominium shall come into existence except by the recordation of condominium instruments pursuant to this chapter. No condominium instruments shall be recorded unless all units located or to be located on any portion of the submitted land, other than within the boundaries of any convertible lands, are depicted on site plans and floor plans that comply with RSA 356-B:20, I and II. The foreclosure of any mortgage, deed of trust, or other lien shall not be deemed, in and of itself, to terminate the condominium. Notwithstanding any provision of law to the contrary, if a rent increase is made in accordance with RSA 356-C:3, I(a)(12), application for condominium conversion shall not be made until 3 months after such increase.
