Property owned by Partnership Firm - all partners dead

Hello, A partnership deed was made in 1992 with 2 partners X & Y. It is neither registered nor notarized. A MIDC plot held by X in his individual capacity first was transferred to this partnership in 1994. After the X died in 2002, no partnership deed was excecuted or registered between Y and legal heirs of X. Thereafter Y died in 2006 and no partnership deed was excecuted or registered for taking legal heirs of Y as partners. So the queries are as follows: 1) What is the status of the partnership firm? 2) What can be done further about the plot if none of the legal heirs of X & Y are partners in the firm?
