Well, the facts relayed are a bit sketchy. No lawyer would advise a person to evade service, but a trial subpoena is normally not effective until and unless served; the party seeking to call a witness can offer alternative evidence (depositions, perhaps affidavits) for witnesses whose presence was attempted to be secured but who are "unavailable." If unsure, the best advice would be to actually consult with a family law specialist, explaining all the facts and circumstances, since items not mentioned could be very important to the question you seek to ask.
