make sure they both agree and you should be ok.
question: i have a long-term tax client who is going through a divorce and have been asked to meet with both spouses (soon to be ex-spouses) to perform tax and financial planning services. is representing both of them a conflict?
answer: it has the potential to be a conflict if not handled properly. here is an engagement letter that martin h. abo, cpa/abv/cva/cff uses in such circumstances. it is included here with his permission.
