You can always sue, the real question is can you prevail. First, "asset protection" is not a recognized area of law, so you need to know if you were dealing with an attorney. Check with the New Mexico state bar association to see if the planner you were working with is an attorney. If she is, you can pursue a complaint to the bar association. If she isn't you might want to report her to the bar association for unauthorized practice of law and you might also contact your local Attorney General's office and file a complaint. If you paid her the $1,500, you should beable to press her to return your fees - but if you're out $1,500 because you had to pay for dental care, that will be difficult to recoup.
