The POA on your deceased mother's name shall not be considered as title deed.
Generally, the principal has the right to terminate the Power of Attorney whenever he wills to do so. Some of the conditions for revocation are ( by virtue of Section 201 of the Indian Contract Act, 1872):
- If the principal revokes the Power of Attorney granted to the agent.
- If either the principal or the Power of Attorney holder or both become unsound of mind, die or is/are adjudicated as insolvent by the court.
- If the Power of Attorney holder renounces his powers.
- If the business for which the Power of Attorney was granted gets completed.
Power of Attorney may also be revoked if there is an implied revocation of the Power of Attorney or in case of time barred agency, the term of the Power of Attorney expires.
Your mother is the POA holder and she is reported to have died hence the POA deed stands revoked automatically, therefore the Will executed by her is not enforceable in law.
Section 202 of the Indian Contract Act, 1872 reads as:
“Where the agent has himself an interest in the property which forms the subject matter of the agency, the agency cannot, in the absence of an express contract, be terminated to the prejudice of such interest.”
Therefore, by virtue of this section, a power of attorney can not be revoked by the principal without the consent of the agent if the agent has an interest in the subject matter of the Power of Attorney. Moreover, such Power of Attorney is not deemed to revoked even after death or insanity of the principal.
However here the situation is that the power agent herself is died, hence section 201 (2) will be applicable to this situation.
