Schizophrenia is a serious mental disorder characterized by irrational thinking, disturbing emotions, a change in personality of the affected person, changes in their emotional life, behavior and relationships with other people. This can affect people at any point in their life, including elderly people.

If a person who is deceased has left a legal will (i.e. signed by two witnesses, dated etc.), it remains valid even if one can prove that the person had been affected by schizophrenia at some point in their life. In order to invalidate the will, the person needs to prove to the court that the person was of unsound mind (for example, due to schizophrenia) at the time of writing the will.

The burden of such proof lies on the person who is contesting the will. In the absence of such proof, the will remains valid.
