Necessity of Resolution

Sir,

Can any one advise on the following:-

A private limited company is a partner in a firm registered with Registrar of Firms. All the directors are partners in the firm. The Partnership is willing to acquire a property in its name. Whether it is necessary to pass  a resolution of share holders or Board of Directors in a meeting at Gm or BOD Meeting for purchase of property by the firm?

Kindly provide suggestions / advice on the matter stated supra.

Thanks in Advance
