I agree to have an agreement with the lawyer. See to it that you have an engagement agreement that would stipulate your mode of payment for things like acceptance, hearing & disbursement fees. Per my former boss who is now a Judge, it is best that in all stages of the proceedings, as a Petitioner in this case, you must be present at all times. Be careful when choosing a lawyer. Always ask for a hearing report & be furnished with all the legal documents that the lawyer files/receives.
