can my ma in law still able to sign cheques once she has made her son power of attony. there are cheques being paid to various people who we can not acount for, ma in law is 96 and finds it difficult to remember where the cheques have gone.
Once he has the power of attorney he can have the bank require either his or BOTH his and hers on the checks. That way she can't sign alone. The simpler solution is to not leave any blank checks and instruct the bank not to issue new ones without his approval.
Will she agree to give you all the checks? I am pretty sure power of attorney allows son to sign for mom without stopping her. Would need to have her found unfit, which I assume he would rather not do.
