Dear client,
Whether or not the previous will of 1980 becomes invalid depends on the language used in the 1992 will. If the 1992 will specifically revokes or supersedes the 1980 will, then the 1980 will may be considered invalid. However, if the 1992 will does not mention the 1980 will or the properties covered by it, the 1980 will may still be valid with respect to the properties covered by it. The exact interpretation of the two wills will depend on the specific language used in each document and the laws of the jurisdiction where the properties are located.
The question of whether the properties are self-acquired or joint family properties will depend on the specific facts and circumstances surrounding the acquisition and ownership of the properties. In general, if the properties were acquired through the efforts or earnings of one person, such as your father in this case, they would be considered self-acquired properties. However, if the properties were acquired through the joint efforts of multiple family members, they may be considered joint family properties. You may need to provide evidence of the source of funds used to purchase or maintain the properties, as well as the intent and actions of the family members involved, to determine whether the properties are self-acquired or joint family properties.
The validity of the 1992 will and its effect on the 1980 will will depend on the specific language used in each document and the laws of the jurisdiction where the properties are located. If the 1992 will revokes or supersedes the 1980 will, the 1992 will may be considered the valid will with respect to all the properties. Again, the exact interpretation of the two wills will depend on the specific language used in each document and the laws of the jurisdiction where the properties are located.
