If there are two properties situated then they should be mentioned in a single will only. If two wills are made, then in that case the second shall be operative by law and the first will be ineffective and shall be dealt with by the succession law. So it is recommended that all the properties should be covered by a single will only.
In any Will the person making it confirms and certifies that it's the latest and last Will. Hence, writing two wills, although relating to different properties is likely to create confusion besides giving rise to possible litigation rendering certain property being left out in the category of in-testate.
Therefore , you can make Will mentioning full details of all the properties in the Schedule, and you can Will each property to whomsoever you want giving a clear reference in as per the schedule.
