Change your Power of Attorney as soon as your divorce lawyer says its legal allowed.
If you have given your spouse the authority to make financial or medical decisions on your behalf, and you don’t create a new overriding POA even after you have divorced your spouse, they still have the authority to act for you.
General Power of Attorney. The person selected can perform almost any act as the principal, such as opening financial accounts and managing personal finances.
Medical Power of Attorney. This designates another person to act on your behalf and making medical decisions if the principal becomes incapacitated.
Remember to Revoke Your Old Power of Attorney
A Power of Attorney can be revoked in a few different ways. First, a new signed document must be drafted stating that the old Power of Attorney has been revoked. The new Power of Attorney must say that all previous such documents have been revoked. Give signed copies to the new Power of Attorney as well as a trusted friend or family member.
Also, change your will, living will, life insurance beneficiary, retirement plan beneficiary, and your legal guardian paperwork for the children.
