Since it is not possible to enjoy the property jointly, you can issue a legal notice to your paternal uncle to agree for an amicable partition to divide the property and to have separate possession of each individual's share in the property.
If he is denying or refusing to the concept of amicable partition yo may file a suit for partition seeking division of property in two equal shares by metes and bounds and to allot one such share to you and your mother and also you can file an application in the same suit seeking injunction order to restrain your uncle to not alienate or encumber the property in any manner till the disposal of the main suit for partition.
You may consult a local advocate and proceed as suggested.
