Senility Law and Legal Definition

Senility refers to the mental feebleness or impairment caused as a result of old age. A senile person is recognized to be incompetent to enter into a legal binding contract. Such a person will not be able to execute a will. Senility is also termed as senile dementia.

In re Rodgers, 1980 Pa. Dist. & Cnty. Dec. LEXIS 458 (Pa. C.P., Orphans' Ct. Div. 1980)], it was observed that the term senility often brings to mind the elderly person who has become moody, cranky and even eccentric. It was the legislature's intent that such persons must not be committed involuntarily on account of those personality changes due to aging which are not tantamount to a severe mental disability.
