Dear Mr. Harish,
In my humble opinion it is not possible. However, a new company could be set up, under Sec. 25 licence, and the property of the trust could be acquired by the Company, with all the trustees becoming members of the section 25 Company.
Again, this will not in any way change the character of the trust, and all capital gain taxes and stamp duties will be applicable. Also, the trust will have to be dissolved, and regarding sale of property the provisions of the Trust Deed are supreme.
Request other expert members to also give their views.
Regards,
Ulhas
