In addition, please kindly check the available time of your notary public lawyer during Jan. 20, 21 and 22.I ask you to check in advance because, if all of you decide to sign the power of attorney, I am afraid that he will not be at his office during Jan. 20-22.Any way, if all of you decide not sign, it is up to all of you.My father only would like to protect your interest before too late for correction.
