I would recommend that you meet with an estates attorney to create a trust to accept donations.
The answer given does not imply that an attorney-client relationship has been established and your best course of action is to have legal representation in this matter.
People have a particular interest in a divorce case? As my colleague suggests, a trust, and MOST CAREFUL records.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
